15 best primers

Such a paintwork material as a primer finds a wide range of applications. The main task of the soil is to create a special layer between the base and the finish. The formed substrate should have good adhesion (adhesion) with different materials. Today in the domestic market one may encounter abundance, expensive and cheap products are offered to the consumer, in small jars of 0.5-1.0 liters and in huge canisters of 10-20 liters. In order not to be mistaken with the choice, it will be useful to get acquainted with the recommendations of experts.

1. Purpose. First of all, before buying, you need to know on which surface the composition is planned to be applied, and what type of finishing will be used in the future. This is a very important point, because different materials are characterized by their ability to absorb. If it is important for metal products to create a good protective layer on the surface, then the primer should penetrate deep into the wood or concrete. After such an operation, the consumption of paint, glue and plaster will significantly decrease. The concept of versatility is not always an advantage for a primer, so it is better to give preference to specialized formulations.
2. Recipe Many different formulations of primer have been invented, they all have a common basis. The active substance may be of acrylic, alkyd, polymer or epoxy origin. Water or organic compound is most often used as a solvent. But the additives created a large number. Antiseptics prevent the appearance of mold and fungi, the introduction of silicones increases the water repellency of the soil, polymer additives increase the depth of penetration.
3. Penetration depth. One of the most important parameters of the primer is the degree of penetration into the base. Maximum impregnation depth is required for porous materials. This is concrete, cement-sand plaster, wood. The depth should be between 10-15 mm. But for metal parts it is more important to create an anti-corrosion layer on the surface with good adhesion. In this case, the penetration depth may be minimal (up to 1 mm).
4. Drying time Since the priming operation is an intermediate in the process of repairing premises, buildings or cars, the composition requires the fastest possible drying. The best option is 1-2 hours, this time can be used for lunch or preparation for finishing.
5. Cost and expense. The cost of a primer in the Russian market seriously fluctuates, even for products of one brand. The fact is that many well-known companies have established joint production in our country, where paints and varnishes are produced. The quality is not always comparable to the original products, but the low cost is pleasantly surprising. In addition to the price tag, it is important to know the primer consumption for each type of substrate. Often cheaper primer requires a 2-3-layer application, which leads to increased consumption.This point should be considered when comparing multiple products.
