What is the best penetration primer? Types of primers. Specifications

In the construction and finishing works, intermediate preparatory stages are very important, since the service life and reliability of the finished surface will depend on them. One of these stages is priming. Since all materials are different, and there is no universal means of processing, in each individual case they select their own special coating. Consider primers of deep penetration. When are they used, how do they work, and what functions do they perform?

What surfaces need to be processed?

The surface to be repaired may consist of a variety of materials: wood, plaster, gypsum or cement-sand, concrete. All of them have different state and properties, which can affect the graspability of the finishing materials among themselves and the further quality of the finishing service. To minimize the risk of detachment from each other and to best prepare the working surface, it is necessary to coat it with a primer over the appropriate material.

Appointment and properties of deep penetration formulations

The primer of deep penetration is used to prepare surfaces that have different properties that can help improve the quality of the finish:

• Increased water absorption of the substrate;
• Fine surface porosity;
• Base, which includes sand and various mineral constituents;
• Chalk marble, dustiness, etc.

The primer of deep penetration lowers the ability of the working surface to absorb water, improves the surface properties of loose materials, making their structure stronger.

How to make a choice?

What is the best penetration primer? When choosing the material for surface treatment, you should not lean towards the cheapest options. This is the case when the miser will pay twice: practice shows that the compositions of the lowest cost do not provide the necessary qualities for further work, the applied construction materials do not have reliable adhesion to the base, the wallpaper is peeled off, and the plastering and other finishing coatings exfoliate from the walls, ceilings, Sexes. Reliable is the primer of deep penetration, the price for which starts from 400 rubles per 10 liters.

In addition to the price, you should pay attention to the manufacturer - the products of known brands usually correspond to a high level of quality. Increased demand among large and individual developers using the primer "Ceresite" and "Optimist." These compositions have high technical characteristics, as well as an optimal ratio of price and quality. To understand which primer of deep penetration is best, pay attention to the description of the material, you can even find and read reviews.

Priming composition "Optimist"

Primer "Optimist" of deep penetration is made in Russia, perfectly adapted to the materials used in the country, climatic conditions and other features of the treated surfaces. It is suitable for use both outdoors and indoors. The basis of the primer is an acrylic polymer that provides deep penetration into the surface and good surface-bonding properties. The composition includes antiseptic additives that prevent the development and growth of fungi, mold and other microflora.

Primer "Optimist" of deep penetration is used for the surface treatment of concrete, brick, cement-sand plaster, gypsum board, wood. And the composition should be applied before each subsequent stage of finishing, which will ensure reliable adhesion of materials. The applied primer layer after drying becomes transparent, colorless, equalizes the absorbing capacity of the surface and reduces the application of paint, varnish, water dispersion and plaster compositions.

This product is also used to dilute paints on a water basis.

Technical characteristics of a deep penetration primer "Optimist"

• Entering the surface: 1-5 mm.
• Consumption depending on the condition of the surface: 100-250 ml / m ² .
• Drying time: 2 hours.
• Without smell.
• Color of liquid composition: white.
• Conditions of application: in rooms with air temperature and working surface + 5 ... + 35 ^о С.
• Storage conditions: in the original packaging in closed form at a temperature of + 5 ... + 30 ^о С for 1 year.

The product has many quality certificates.

Description of the deep penetration of Ceresit

Primer "Ceresite" is also popular among builders. The products of this manufacturer are of high quality, have a complex, improved composition, are manufactured using German technologies.

The primer is used for all surfaces with an absorbent base: walls, floors, ceilings. Increases the adhesion of the working surface, binds the dust, strengthens the base. Prevents the drying of thin leveling compounds, promotes better spreading of floor coverings and eliminates the appearance of bubbles on the finished surface.

Primer "Ceresite" works well with strong porous substrates: it penetrates into their structure in the best way and strengthens it as much as possible. And for such cases, the emulsion is diluted with water in a proportion of 1: 1 and applied in several layers if necessary. Due to its composition and ability to penetrate deep into the surface, the primer dries for a long time (4-6 hours). When used on gypsum and wood boards, the drying time increases to 24 hours.

The main technical characteristics of the Ceresit primer

• The basis of the composition: copolymers of acrylate.
• Color of solution: light yellow.
• Consumption depending on the absorbency of the surface: 100-200 ml / m ² .
• Drying time: 4-6 hours (in some cases up to 12 hours).
• Application: at humidity of air no more than 80% at temperature from +5 ... + 35 ^о .
• Storage: in a closed container at a temperature of + 5 ... + 35 ^о С no more than 12 months.

Comparison of compositions "Optimist" and "Ceresite"

Which primer of deep penetration is better: "Optimist" or Ceresit? It is difficult to answer unambiguously, since for each specific application area, despite their universality, is suitable. Analyzing the technical characteristics of these samples, it's hard not to notice: "Optimist" is more suitable for surfaces that do not have high porosity, which the German representative will better handle due to his more complex adapted composition. For example, when preparing a concrete foundation for the device floors.

For ordinary surfaces of brick, blocks and plaster, any primer of deep penetration is suitable. The consumption per m2 is the same for one layer, if we compare the coatings with the same porosity. It is the structure of the base that affects this factor.

In many cases, one primer for deep penetration is applied to the whole object. The price in this case is important: "Optimist" costs from 400 rubles / 10 liters, "Ceresite" - an average of 550 rubles / 10 liters. These are the average indicators that imply the optimal quality of the goods. There are also expensive premium compounds.

Primer for metal surfaces and wood

Before painting of wooden elements and metal, it is also necessary to prepare the substrate. For this purpose, a special primer has been developed in Russia, GOST 25129-82 gives its description. The make grade is GF-021. It is made by different manufacturers, but they all adhere to the State Standard.

Primer GF-021 has a general industrial purpose, is a paint and varnish material. Provides uniform application of paint and varnish.

Main technical characteristics:

• Color: red-brown;
• Flow rate: 60-100 g / m ² for single-layer application;
• Drying time at a temperature of +20 ° C: 10-16 hours / layer.

Before use, the primer must be mixed, diluted with white spirit. During work, the room needs to be ventilated. The composition should be stored in tightly closed containers away from sunlight.

When choosing a primer GF-021, look for the inscription GOST 25129-82 on the package. In this case, you will purchase a product that is manufactured according to the standard. The inscription TU indicates that the manufacturer has made its changes in the composition, which may affect the final properties of the coating.

What is the best penetration primer? Choose compositions carefully, read the technical specifications, use your own or someone else's experience. Choose a material that is suitable for specific conditions, then the result is sure to please.
