Simple ways to make your own primer

The role of primer in construction and installation work is of great importance. Its main feature is improved adhesion of materials. In addition, it has a wide range of advantages in use. Depending on the requirements and areas of application, you can find different types of primer compositions in stores. But if you wish, you can make a primer yourself. It consists of affordable materials, glue is used as a base and this significantly reduces its cost.

Making your own primer at home

Before further finishing, the surface is treated with a layer of primer to create a reliable fastening. The construction market offers a large number of available ready-mix options. Do-it-yourself primer is in no way inferior in quality to store-bought counterparts if used correctly.

Is it possible to make your own primer at home?

The soil not only improves the adhesion index, but also extends the service life of the product as a whole. This is a liquid mixture that is distributed evenly over the surface. As it dries, a protective film is supposed to be created, on which other materials are then laid.

The answer to the question of whether it is possible to do primer at home at all will be positive. It is enough to study the composition of store options, and then get the components for free sale.

The only exception may be wood processing; in this case, it is better to refuse homemade options. Next, we’ll tell you how to make a primer from PVA glue.

Homemade primer versus store-bought primer, which is better?

Materials include simple substances in the composition. They are freely available and much cheaper than buying a ready-made mixture. All you have to do is follow the recipe and make sure the proportions are correct.

Materials include simple substances in the composition.

Classification and methods of cooking at home, what components are needed

Coatings without proper treatment do not retain any materials. Such compositions are especially important for bases where several materials are present at once. Each variety has its own purpose, but there are some differences when making your own primer for walls.

Coatings without proper treatment do not retain any materials.

For painting

Here you can also use PVA glue. If everything is done correctly, a film is formed that is almost invisible from the outside. The main thing is to make sure that there is not too much glue when adding to the water. Otherwise, over time, such a surface deteriorates, parts separate from each other. Even if it's drywall.

Quick priming is a must even for those who have no experience in such work. It is recommended to follow these tips for better results:

1. Before treatment, remove all dirt and old paint and varnish materials from the surface, if any.
2. The mixture is poured into a special container; application involves the use of brushes or rollers. Then the convenience will be maximum. The first step is to process corners and hard-to-reach surfaces. The craft gives results immediately.
3. Movements go from top to bottom.
4. The second layer is applied only when the first one is completely dry. Then the clutch will become more reliable, and it will be easier to move on to other decorative work. The paint spreads without problems.

If there is not enough solution, prepare a new one. Only the container needs to be thoroughly cleaned, otherwise lumps will appear. Priming will not work effectively. When applying primer, it is recommended to avoid using sprayers; this will increase the risk of damage to the primer.

The second layer is applied only when the first one is completely dry.

Any solutions prepared independently are stored for one day, no more. Otherwise, the original qualities are lost and painting is impossible.

The walls are covered with compounds after completion of all primary work. When repairing and restoring elevations, soils will be needed to increase the strength of the foundation. For preparation, you can use any of the recipes described above.

Such materials are suitable for bricks that have begun to crumble. Copper sulfate can be easily purchased by visiting gardening and gardening stores.

Hardware stores will help with the rest of the components; they can also be applied to the floor.

The walls are covered with compounds after completion of all primary work.

The need to visit stores does not always arise if the required type of primers is not available. It’s easier to gather available ingredients on hand to prepare the mixtures yourself.

Their quality is no worse than other analogues. The only drawback is the shelf life, which is only a day. Without its observance, one may not think about the long-term preservation of the original qualities.

Only the liquid form of the primer qualitatively fills all the pores on the surface, this should also be remembered.

Application Features

Priming walls can be done quickly even if there is no relevant experience. To ensure quality work, it is recommended to follow the following rules:

1. Before priming, it is necessary to prepare the working surface, namely, clean it of old coating, paint, dirt and dust.
2. For convenience, pour the mixture into a special container and treat the walls with a brush or roller. First of all, corners and hard-to-reach areas should be treated.
3. Movements should be from top to bottom.
4. After the first layer has dried, apply the second. This will ensure reliable grip and allow you to move on to decorative work.

If there is not enough primer, then before preparing a new one, you must thoroughly wash the container to clean it of the old mixture. If this is not done, lumps will appear.

Do not use spray when applying primer, otherwise all furniture and other interior items will be damaged.

If during the repair process you don’t have a primer on hand, then you shouldn’t immediately run to the store. Make the mixture at home. If you strictly follow the recipe, you will get a quality product. Easy to prepare – deep penetration primer based on PVA. The main condition in the process of its creation is compliance with the proportions specified in the recipe.

What materials to use after PVA primer

After applying a primer made from PVA glue, different types of finishing can be produced. A thin protective film seriously reduces paint consumption and makes it easier to apply. This primer is ideal for acrylic and latex paints, as well as alkyd enamels.

After priming the walls, you can paste them with wallpaper: paper, vinyl, non-woven, using any wallpaper glue. To increase the strength of the connection, PVA is also often added to the glue. The primer composition is suitable for ceilings that are planned to be finished with polystyrene foam tiles: the degree of adhesion will increase.

Choosing a base for priming

When performing construction work, the importance of priming cannot be underestimated. How to prepare a primer from PVA glue? A special composition penetrates into small cracks and crevices, makes the surface smoother and more even, and improves adhesion. After applying the primer, you can use any paint and varnish materials and glue wallpaper to the walls.

Thanks to the use of the base, it is possible to achieve savings in expensive paints and enamels.

Why use a primer

Before you start preparing this mixture, you need to figure out what exactly it is for and what it is. Yes, such a solution can be different - each type can be used to improve the properties of a specific surface. The main purpose of using a primer mixture is to enhance the adhesion of the finishing material and the base. If you carry out repair work without using a primer, the finish will last a significantly shorter period.

Moreover, some types of paints simply cannot adhere to an unprepared substrate, especially if it is smooth. This is why you need to use a primer - to give the base the necessary properties.

Priming is a mandatory stage of preparatory work, which affects the quality of the entire finish.

Regardless of their composition, all primers perform the following tasks:

• improve adhesion between the base and the material;
• prevent cracking of the bottom layer;
• reduce glue consumption during wallpapering;
• protect walls from excess moisture;
• allow you to level out deformed areas.

What destroys a tree?

Wood is an extremely unstable material that is destroyed due to exposure to external factors. We are talking not only about cases where houses are built entirely from wood, but even about furniture. The main reasons that contribute to the destruction of wood are:

• clay bacteria;
• fungi;
• grinder beetles;
• moisture.

Clay bacteria can weaken the structure of wood in a short period of time, and fungi, even after they are removed, leave dark spots. A humid environment produces mold spores that destroy wood products. In addition, mold can cause deterioration in human health.

Fortunately, you can increase resistance to such external factors with the help of special antiseptics. They must be used at every stage of house construction, as well as:

• during the production of lumber;
• during the production of furniture, building materials from wood;
• at high humidity.

Primer for walls. Kinds

The primer can be made on different bases and from different components. Based on this, there are several types of this building material: acrylic, mineral, quartz, alkyd, phenolic primer.

Let's take a closer look at each type of primer:

1. Acrylic. The main component is acrylic polymer. This mixture is suitable for bases made of brick, cement, concrete and wood. Acrylic primer can be water-based for treating walls with water-soluble emulsion paints and enamels. The undoubted advantage of this material is the complete absence of odor and good drying speed. In just 2 hours the surface will be completely dry and you can begin the next stage of repair work.
2. Mineral primer is made with the addition of lime, gypsum or cement. It is used for processing brick, concrete, gas silicate brick and plastered surfaces. The packaging should indicate for what type of substrate the mineral primer can be used. After treatment, the coating will dry in 2 hours.
3. Quartz primer. The main component is sand. An ideal product for improving adhesion, since after treating the wall a rough layer remains on the surface. An ideal material for working with decorative plaster and paint.
4. Alkyd primer - it contains phosphate and zinc chromate, which prevent the formation of rust on the surface. This primer is suitable for treating wooden surfaces, glass, metal and ceramics. Alkyd primer should not be used on plasterboard or concrete walls. It takes a long time to dry, so you will have to immediately be patient and take a break of 12-15 hours after applying the primer.

We have listed the main types of primer. In the construction supermarket you can see a large selection of different primer mixtures. Remember that they are all divided into 2 groups:

1. Adhesive.
2. Strengthening.

Therefore, in order to make the right choice, you need to decide on the type of finishing material.

Drying time

Many people are interested in the question of how long it takes to glue wallpaper after priming.
This directly depends on the percentage of water in the mixture. Other indicators are also important: the optimal temperature in the room is 20 degrees Celsius, atmospheric humidity is 70%. It is best to follow the drying times indicated on the label, since with a similar name from different manufacturers, the solution may contain special substances that affect the drying speed. Approximate drying times for different materials are presented in the table.

View	Surface	Time
Concrete contact	All	6 hours
Latex	All	40 min
Universal acrylic	concrete	from 1 to 3 hours
drywall	12 h
brick	from 6 to 8 hours
plaster	from 2 to 4 hours
Deep penetration primer	All	24 hours
Mineral	concrete	from 2 to 6 hours
Alkyd	tree	10-12 h
metal	10-15 h
Glyphthalic	metal	24 hours

The main mistakes made when drying:

• drafts - open windows and doors will cause uneven drying;
• using a hairdryer or heat gun - the outer layer of the mixture will dry faster than the inner one;
• temperature changes - the lower the temperature drops, the slower the material dries.

What soil is needed for seedlings: soil composition

The soil for seedlings often includes sand. It is best if it is clean river sand that does not contain clay. It is enough to sift it to clear it of stones. Soil containing sand never forms a surface crust, which is a big plus.

When preparing soil for seedlings, refrain from using quarry sand, since it always contains clay and may contain toxic impurities such as iron or manganese salts (the brightness of the color of the raw material indicates their presence), which negatively affect plants.

In recipes for mixtures you can find manure or mullein. If you grow seedlings in an equipped greenhouse, there are no contraindications to their use. In the event that we are talking about residential premises, this issue must be approached with knowledge of the matter.

Manure happens:

• fresh, in which the straw is clearly visible;
• half-rotted, the straw is still visible in it, but it has already darkened and is easily torn;
• rotted, representing an almost homogeneous (homogeneous) mass;
• in the form of manure humus. This is the best option, since in such manure the nutrients are in the form that is most accessible to plants.

What kind of manure for soil is better when growing seedlings in a residential area? At home, only manure humus can be used as a component of the soil mixture, which is good not only from the point of view of hygiene and aesthetics, but is also beneficial to plants.

When preparing soil for seedlings, compost is also used, which still needs to be properly prepared, since the pile in the corner of the plot, consisting of food waste and weeds, has absolutely nothing in common with a real compost pile. If heating is not provided during its preparation, then plant debris and everything else that is usually put into compost will simply slowly decompose, losing nutrients and accumulating harmful microorganisms.

Coconut substrate for seedlings

Gardeners have recently been willing to use home-made coconut substrate as seedling soil, which is environmentally friendly, consisting of 70% coconut fiber and 30% recycled coconut palm husk. For seedling soil, coconut substrate can be mixed with peat in a 1:1 ratio. If you do not include peat, you will have to periodically fertilize with a weak solution of fertilizers.

Using a coconut substrate, a favorable breathable environment is created for the formation of a powerful root system of seedlings. The coconut mixture gives clay soil looseness and increases the moisture capacity of sandy soil. This substrate can also be used as mulch, protecting the soil from overheating and drying out.

Seedling soil from coconut substrate is prepared according to the instructions on the package: 1 kilogram of substrate is designed for 15 liters of water.

To obtain, for example, 4 liters of soil, you need one and a half liters of warm water, where you should put a briquette of the substrate and give it 10-15 minutes to swell. After this time, the briquette will increase many times in volume and become loose and porous. It can be used as soil or included in seedling potting mix.

How to make a primer with your own hands?

Surface priming is a very important process in construction and repair. Don't forget about him. Sometimes you can make your own primer. This way you can save your money.

Peculiarities

Primer mixtures are auxiliary finishing materials. Their purpose is to modify the properties of the surface on which they are applied. In this case, various goals can be pursued, such as improving the protective properties of the material, for example, moisture resistance, protection against corrosion, or enhancing adhesion between the surface and the finishing material subsequently applied to it.

Thus, the use of a primer significantly affects the quality of finishing work, their strength and durability. Moreover, the various properties of primer mixtures depend on their composition.

Primer requirements:

Strengthening adhesion. Different types of surfaces - wood, brick, metal, concrete - have different properties, as a result of which the strength of the connection with different finishing materials varies greatly. To ensure strong adhesion of the decorative finish to the base, a primer is used. It strengthens the bond between materials at the molecular level, creating an “alloy” of contacting surfaces and the primer mixture in the boundary layer.

Increased moisture resistance. Some materials are porous in structure, such as wood or concrete. Moisture can accumulate in their pores and eventually lead to the destruction of the material. To prevent such phenomena, the working surface is treated with a primer solution, which fills these micropores and saves the material from damage.

As a result, two positive effects are achieved at once:

1. waterproofing increases, since water can no longer penetrate the surface,
2. the consumption of glue, paint, varnish or other finishing material applied to the treated surface is reduced due to the clogging of micropores with a primer.

• Strengthening. The primer mixture creates a protective layer on the surface that absorbs the effects of an aggressive environment. The nature of the protective properties is determined by the specific composition of the primer and can vary depending on needs.
• Antiseptic protection. To prevent fungus and mold from multiplying in places with high humidity, the primer mixture includes an antiseptic that prevents the activity of harmful organisms.

Homemade primer mixtures are divided into several types according to their main purpose. Unlike factory primers, homemade ones do not contain additional synthetic additives that expand their functions in several directions, but perform one main task. Thus, all homemade primer mixtures can be divided into the following types:

Strengthening. This type of mixture is designed to increase the strength of the surface being treated, such as a plasterboard wall or ceiling. Such primers are widely used in old houses, especially with wooden supporting structures, where it is not possible to replace beams or wooden floors that have begun to deteriorate over time.

How to make a primer with your own hands?

The primer can be made at home with your own hands. How to make a primer for walls using PVA glue? What are the requirements for a primer? What types of primers exist on the construction market?

What is a primer and its composition

Experts recommend using a primer to improve the quality of the repair. The material is also used to ensure that the finishing fits better, so that mold and mildew do not form on the walls in the future, and damage to the external coating does not occur. Compositions can vary significantly depending on the type of soil and its purpose.

What types of primers are there?

Manufacturers offer several different primer options. Most often, specialists take into account the composition of the material when choosing.

If a person has insufficient experience in construction, then it is best to take into account the purpose of the solution.

In addition, mixtures may differ in additives that provide the primer with additional characteristics or enhance those that are initially present. Next, we will consider the most popular soil options that will help improve the results of the repairs.

If you select the material yourself, then you should definitely take into account the condition of the base and what type of finishing will be used in the future.

This will allow you to choose the most suitable mixture option, which will help make high-quality and durable repairs.

If there is a need to save money or you need very little composition, then you can prepare it yourself at home. To do this, you will need a minimum number of simple components and follow the instructions provided below, adhering to certain proportions.

Making your own primer

Preparing a primer with your own hands will require a minimum amount of time and materials.
In this case, it is very important to follow the instructions and maintain the proportions in order to obtain a solution with the desired characteristics. Composition for deep penetration

The simplest and most popular option for homemade soil today is considered to be a deep penetration mixture. The main component of the solution is PVA construction adhesive, which can penetrate quite deeply into the base and protect it from moisture and damage. The composition, after application and complete drying, creates a thin waterproof film, binds dust particles together and does not negatively affect ventilation. It is very important in this situation to maintain the proportions correctly. Otherwise, the film from the adhesive solution will begin to peel off in the future along with the finishing materials.

To prepare, you will need 8 liters of clean water and a cement trowel per liter of PVA glue. If possible, cement can be replaced with ordinary powdered chalk. First, thoroughly mix the glue and water together. Next, add cement and stir the solution until smooth. Lastly, the homemade primer must be carefully strained through cheesecloth to remove any lumps that might remain in the mixture.

The resulting composition should initially be tested in one area. After the soil dries, no film should appear. If it has formed, then a little more water is added to the solution. Walls covered with the mixture should have a slight whitish tint.

Strengthening

Such compositions are in most cases used for repairs or restoration of old premises. They can be used quite often during insulation. Such homemade soils are needed to make the foundation more durable. The material is especially often used for treating brick, concrete or porous substrates.

The recipe for making a strengthening primer is quite simple. It will take a minimum amount of time to prepare, and the result will pleasantly surprise everyone. You will need to take 100 grams of copper sulfate, half a liter of wood glue, and a bar of laundry soap. All components can be purchased at any specialized store, and their cost is more than acceptable. The preparation of the primer should be carried out in accordance with the following recommendations.

First, bring 7 liters of water to a boil. After the water boils, the fire should be made as low as possible. While stirring the water all the time, grated soap is added to it. When the mixture becomes homogeneous, you can add glue, and then vitriol. The resulting solution is boiled over low heat for another half hour. If it was not possible to prepare a primer without lumps, then they must be thoroughly broken up using a construction mixer. After partial cooling, the resulting composition is filtered through several layers of gauze and left until it reaches room temperature.

Such a homemade composition will be an excellent solution if you need to not only strengthen the base, but also protect it in the future from the formation of fungus or mold.

Advantages and disadvantages

Construction stores offer a huge selection of high-quality primers, but they have a considerable price. How to prepare a primer from red lead? It will be much cheaper to prepare the primer yourself.

A homemade primer solution is based on the use of PVA construction adhesive.

PVA glue provides the following functions of a regular commercial primer, such as:

• increased adhesion;
• sufficient water resistance;
• If antiseptics are added to the solution, antibacterial properties will also be present.

But, despite these advantages, such a primer solution may peel off from the surface over time due to improper mixing of the glue with water. Also, the glue turns yellow after a while, and these spots appear on the front side of the decorative coating. This can be avoided by applying a thick layer of finishing coat (such as paint).

Thus, if external beauty is not very important, or if expensive wallpaper or paints will not be used, then a self-prepared primer based on PVA glue will be very useful.

The best option for wallpaper

The most effective method, which will significantly save time and provide a high-quality result, is mixing wallpaper glue with a regular primer. This composition ensures maximum penetration depth and firmly fixes the wallpaper.

The main advantage is that after applying the composition to the wall, you can immediately glue wallpaper onto it. Before applying the primer, you must thoroughly clean the wall of any debris. It is better to apply it with sweeping movements from bottom to top using a roller.

Alternative primer substitutes can be very useful because they can save you money without sacrificing quality. Each analogue has its own characteristics, which must be taken into account before making a choice.

The base can be ordinary wallpaper glue. This is a replacement for regular PVA for the composition. Protects and penetrates into the pores of the material as deeply as possible. There is no need to wait for drying; the wallpaper is immediately applied to the primer.

Adhesive-type compositions allow for independent preparation. The description of the components is as follows:

• 30 grams of drying oil. Plaster is not needed;
• 2 kg chalk;
• 250 aluminum alum;
• 200 grams of dry chalk for painting group;
• 200 grams of soap from the farm. This is the answer to the question of what primers are made of.

Cooking will not cause problems if you follow the instructions. Only at first glance the composition seems complex. Manufacturers, including well-known ones, use the same components for their developments. The cooking algorithm is as follows:

1. Pour alum into 1 liter of water.
2. Take a separate bowl and dilute glue in it.
3. Make sure to keep the fire low. With constant stirring, add soap, alum and drying oil.
4. Pour in chalk and mix well.
5. Water is added when needed. Nobody is against this option.

Why do you need a primer for walls?

When getting involved in renovations for the first time, people do not pay enough attention to the primer, because they do not know the characteristics and do not suspect how big its role is in finishing. Therefore, the building mixture is often ignored, but in vain. If the base prepared for wallpapering is left without a primer layer, it will be rough; this flaw can only be noticed upon close examination. Such defects are the reason for the violation of the smoothness of the wallpaper and the unpresentability of the premises.

But the purpose of the building mixture is not only to achieve a flat surface. It is successfully used for other purposes, depending on the type and composition of the material used. The advantages of primer are that it:

• gives a smooth and high-quality base;
• makes the surface strong and durable;
• facilitates easy application of coloring and other substances;
• masks wall defects;
• Makes glossy finishes shine.

A well-executed wall primer eliminates the smell of paint and prevents the appearance of mold in the future.

Tips for preparing primer

The use of certain substances can significantly improve the properties of home-prepared wall primers. For example, you can add crushed chalk or a small amount of resin to the building mixture. The composition obtained as a result of such manipulations is ideal for treating walls if they are covered with wallpaper.

A distinctive feature of PVA adhesive-based mixtures is that it is not absorbed into the base and does not make it possible to get rid of microcracks. Preparing a primer for walls at home is best done in a warm room, with the balcony and windows closed.

When mixing, it is necessary to simultaneously work with a stick or a special spatula so that the glue mixture can be completely dissolved in the liquid.

Making a primer

Components for homemade primers are available on any construction market. This composition is made quickly, it is immediately ready for use

The most important thing in the manufacturing process is the correct proportions. Each recipe written below will help you understand how to make your own primer.

Deep penetration composition

You can make a deep penetration primer as follows:

1. Pour glue into the container, add water to the glue and mix until smooth.
2. Add cement or chalk powder to the suspension.
3. Strain the resulting mixture through a gauze bandage.

In the video: primer made from PVA glue.

Strengthening

The primer composition is made as follows:

1. Bring water to a boil and add grated soap into it.
2. Reduce heat and pour glue and copper sulfate into the pan.
3. Keep the mixture on the fire for 30 minutes and stir.
4. Strain the mixture through a gauze bandage.

Wood mixture

Preparation method:

1. Pour alum into 3 liters of boiling water.
2. Dilute the glue with the remaining water.
3. Put the water with glue on the fire and add soap, drying oil and water with alum to it.
4. Mix thoroughly, add chalk and mix again.

Technology

I have good news here. Priming walls for painting, unlike other stages of repair, does not require special skills and is the least labor-intensive process. Primers are sold in cans of various sizes in liquid form. Usually these are 1L, 3L, 5 and 10L.

Their consumption is small, and the remains can always be applied with an additional layer. How many coats of primer should be applied to the walls before painting? Nothing bad will come of this. The tools you will need are a convenient container (usually a paint tray or bucket), a roller (preferably with long pile), a brush and a brush.

For high walls, prepare a comfortable handle. This could be a long branch, a mop, a fishing rod or any other handy item.

A small amount of primer for walls for painting is poured into the selected container. Then, dip a brush or roller into the liquid and carefully apply it to the wall. Don't forget about safety rules.

The primer splashes a lot, so take care of your face and wear work clothes and a hat. Washing primer from your hair is not the most pleasant thing. It is much easier to wash it off from areas of the skin with a small amount of water or by wiping it with a wet cloth.

When applying primer to a wall, you will most likely experience drips. This is not very scary, but still try to avoid them so that the work looks neater. A brush can be used to treat corners and other narrow areas.

For priming high walls, place the roller or brush on the holder and continue working.

It is important that the roller sits firmly on the holder, otherwise you risk getting injured from it falling. After the primer for walls for painting has completely dried, you can apply a second coat.

Before carrying out further work, make sure that the wall is completely dry.

If painting begins with a wet primer, it will begin to fall off along with pieces of plaster and mix with the paint right on the roller. Then it will stretch along the entire wall. Then you will have to start all over again, completely cleaning the wall.

Enjoy your renovation, easy preparation and excellent results!

Useful tips

Recommendations from experts on the use of homemade soil composition.

1. It is best to treat the wall surfaces with the solution using a roller, dipping it into a special plastic tray, which, due to the presence of a large number of ribs, will not allow the roller to absorb a large volume of the liquid composition.
2. When wallpapering walls, you can use a composition made from wallpaper glue to prime the surfaces. The properties of PVA and wallpaper glue are almost identical. They can provide good strength and sufficient penetration. Moreover, when using wallpaper glue as part of the primer, you do not have to wait for the composition to dry out. The wallpaper is glued directly onto the primer.
3. Professional builders advise applying the primer layer in one wide motion from bottom to top. It is necessary to try to apply the primer so that the roller does not pass over one area several times, otherwise the layer will turn out to be uneven. To make the overall layer as dense as possible, you need to let the first layer dry completely, and only then apply the next layers on top of it.

Taking into account all the advantages and disadvantages, all that remains is to determine whether a self-prepared primer is suitable in each specific case or not. Professional solutions can provide protection against the effects of fungi; they do not separate, but the cost of purchasing them is much higher, in contrast to similar mixtures made at home.

How to prepare walls for primer application?

Walls should be carefully prepared before treating with a primer. So, no old finish should remain on the surfaces - it is better to remove wallpaper, paint and plaster. You should carefully inspect the walls for protruding nails or screws, remove baseboards, etc. If necessary, you can plaster or putty the surfaces. In this case, individual areas subject to additional treatment should first be treated with a primer composition, and only then applied to all other surfaces. In some cases, it is necessary to prime not once, but twice, but it is necessary to allow time for the first layer to dry. You can begin the final stage of finishing - painting or wallpapering - after the last primer layer has completely dried.

If the technology is followed, a home-made primer will turn out no worse than its factory counterpart. However, it will allow you to save money, make the wall surface ready for final finishing and achieve a very high-quality result.

How to prepare soil with agroperlite and vermiculite

Perlite is a rock of volcanic origin in the form of small white granules. Vermiculite is a mineral made from mica, a gray friable powder. Due to the similarity of properties, it is necessary to use either one or another useful substance to prepare seedling soil. When preparing home base soil to improve it, you can add one of the named minerals up to 20-25% of its volume.

Both of these mineral soil additives make the soil looser and more permeable. They can even be added to a ready-made purchased soil mixture, because they will give it the very important property of remaining evenly moist for a long time.

Perlite and vermiculite are designed to make the soil for seedlings looser and more breathable. It is useful to add them even to store-bought soil. This will give it additional positive properties, for example, the ability to remain evenly moist for a long time, which will allow you to water less often and will become an obstacle to the plant disease “black leg”.

100 grams of perlite can absorb up to 400 milliliters of water, and vermiculite - up to 500 milliliters of water. After water is absorbed, the process of slowly returning moisture containing fertilizers to the soil occurs. This will allow the seedlings to go without watering for 5-7 days - if necessary, you can leave for such a period.

In addition, both minerals included in the seedling soil, having the property of smoothing out temperature fluctuations, can help the development of seedlings even with the contrast of cold air from the window and hot air from the heating system. At the same time, even warmth is maintained at night. Seedlings of eggplants, tomatoes, peppers, cucumbers and large-seeded flowers grow well with the addition of these minerals.

How can I replace store-bought analogues?

You can not only apply the primer to the wall yourself, but also create it. Usually the composition of mixtures from different manufacturers is similar. On the building materials market you can purchase the components mentioned on the factory product label. From these ingredients you can easily create a product that will not be inferior in quality and characteristics to store-bought counterparts.

Why create a primer with your own hands if there is a huge assortment of them in stores? Firstly, this will save money. You won't have to overpay for packaging and branding. Instead of a store-bought primer, you will get a homemade one, which is no worse. And, secondly, someone will find this idea tempting - making a building mixture with their own hands.

The components for preparing the composition can be purchased on the construction market. The product is made in a matter of minutes, after which it is immediately ready for application.

The only important condition is to check the correct proportions during the manufacturing process

Tips and tricks

Self-prepared primer retains its technical characteristics and provides high-quality coverage only within 24 hours from the moment of preparation. Therefore, you should not make a large amount of primer solution at once. In general, it is advisable not to delay treating the surface with a homemade mixture.

If you don’t have PVA construction glue, you can purchase carpentry or office glue. But it is still recommended not to experiment and use construction adhesive suitable for these purposes.

To stir the primer solution during the manufacturing process, it is better to use a special construction mixer. If you have to work with a regular mixer, then after stirring it must be washed immediately, as it may become unusable. In addition, a construction mixer will help achieve the desired homogeneity of the composition without using much effort.

Before treating the entire surface, it is advisable to make sure that the solution is made correctly and will not peel off. To do this, you need to apply the primer to a small and inconspicuous area.
