Alternative to store-bought primer with recipes

Among the huge number all kinds of building materials there is a product called primer. This is such a binder composition with which the surface is coated at one of the first stages of processing. Then, on the primer, perform putty, plaster, painting or wallpapering. The primer can be bought ready-made in a building materials store, or you can make it yourself according to your own recipes. And your own can be a good alternative to a purchased primer, and even with your own recipes.

What is a primer

The primer is a mixture of resins, polymers, pigments, water. It can be liquid or pasty, ready-to-use or diluted in water. It is needed to create a special film layer, which provides a stronger adhesion between the wall itself and the subsequent finishing material.

The primer makes it possible to increase the reliability of the coupling between the very plane of the wall (floor, ceiling, etc.) and the coating that will be applied to it. Good primer prevents the development of mold, reduces the negative impact of temperature changes and other unfavorable operating conditions. In addition, a good primer reduces material consumption, protects metal from corrosion, and wood from harmful insects.

Types of primers

Deep penetration primers are used when extra strong adhesion of layers is required. The composition is formed on the basis of acrylic and styrene. It evens out and hardens porous surfaces.

Universal primers reduce the moisture absorption capacity of walls. They are applied before sticking. ceramic tiles, painting walls, gluing wallpaper. This primer prevents the glue from drying out quickly when wallpapering walls.

Primers of the "betonokontakt" type are used when working with floor slabs. They protect well against moisture penetration deep into the structure. Also suitable for porous surfaces based on latex, silicone and silicate.

Primers for outdoor decoration are resistant to ultraviolet radiation, variable temperatures and mechanical stress. Alkyd primers are suitable for all surfaces, except metal, and special primers are needed for various metal products.

If the color of the primer is in stark contrast to the color of the surface being treated, it is very convenient to detect gaps in the treatment. If the color of the primer is close to the color of the paint, then the damage to the painted layer will be less noticeable.

When working with a primer, all personal safety measures must be observed. First, you need to choose the right set of working tools - brushes, long-handled rollers, fine-grain sandpaper or a grinder, spatulas, scrapers. You will need a putty and chemical remover, as well as a primer bath. To ensure personal safety, you need to have protective elements - glasses and gloves.

Priming process

The primer prepared for work should be poured into a special bath, into which a roller or brush is then dipped. When applying it is important to evenly distribute the primer over the entire surface to be treated; gaps cannot be left. The priming process takes a long time. The quality of the final result largely depends on its quality.

The liquid primer can be sprayed onto the wall.

DIY wood primer

A homemade primer does not provide any benefit either in terms of technical or economic indicators. Only in emergency situations, when you really need it, and you don't have a branded primer at hand, you can use a homemade product.

For example, for priming wood, you can make a primer based on PVA glue. The glue is diluted with water. Thick glue will be poorly absorbed into the wood, it simply forms a thick film, which after a while will slide off the product. It is better to smear the liquid composition several times, it will be well absorbed and gradually create a strong film. As a result, you can get certain advantages: adhesion will increase on the surface, paint will lay on it more evenly, and its consumption will decrease. Wood will be better protected from water. A homemade compound is inexpensive, so you can get some small savings. But such a primer is short-lived, it will turn yellow over time. It has no antiseptic properties, it is afraid of steam and water. By the way, this thesis is not unconditional. There are defenders of self-made soil, claiming the opposite. Before making a decision, it is necessary to collect more opinions from both defenders and opponents of such a mixture.

Conclusion

An inventive homeowner will figure out how to get out of a difficult situation in any situation. In any business, there are craftsmen who are sure that they can do everything better than the purchased one. And sometimes the purchased one is simply not at hand at the right time, you have to show ingenuity and ingenuity. In any case, the experience of homemade people needs to be studied, you can always find a lot of useful information in it.
