Before finishing any surfaces with such building materials as cement, concrete, gypsum, lime cement and others, it is necessary to process the base with a special compound. Then further finishing will turn out high-quality and will not require repair for a long time.
Primer "Concrete Contact": consumption per 1m2
The primer serves to strengthen the adhesion of the cladding and the machined surfaces, increasing their adhesion. In other words, this composition changes the properties of concrete, brick, slabs, which is very important, since the key to the success of any repair is precisely an increase in the adhesion of materials.
The composition required for use during repair work is the waterproofing and adhesive primer Betonokontakt. The consumption of this product directly depends on how porous the treated surface. More porous require coating in several layers and more thorough processing. Less porous ones are usually coated with a primer once or twice, and the consumption of Concrete Contact per 1 m2 is 0.2-0.5 kg.
"Concrete contact" is used most often before:
- Arrange concrete floors on magnesia concrete.
- Arrange polymer cement concrete floors.
- Arrange screeds on a Portland cement basis.
- Apply levelers, plasters, putties and other finishing coatings.
Considering the example of laying ceramic tiles on a wall or on a gypsum board partition, it is easy to make sure in practice that if the primer is plentifully coated with a primer before applying the adhesive, the tile will stick quickly and reliably.
Due to its technical characteristics, it is effectively used when working with expanded polystyrene, gypsum plasterboards, reinforced concrete, concrete and many other building materials. Concrete contact primer. Its consumption can be called very economical, which distinguishes it from the mass of similar materials.
In addition, this primer is indispensable in preparing for the repair of walls with the remains of old tiles or previously painted with any kind of paint. Sometimes it’s just not possible to completely remove the old tile and remove the paint layer. With the help of "Concrete contact" you can easily prepare the old surface for laying new tiles, while the adhesion quality of the materials will turn out to be quite high.
A distinctive feature of this primer is that it is ideal for poorly absorbent or non-absorbent surfaces.
Operating principle
The primer gives the old ceramic tile or painted wall roughness, in other words, a certain stickiness, which is necessary with such a repeated surface finish.
Why is it convenient to use a primer
Unlike many other primers, this one is sold completely ready to use. The manual only offers to mix the Concrete Contact mixture thoroughly. The expense for upcoming work is calculated according to the instructions. You don’t have to buy any special tools for work, and even a beginner will cope with it.
Primer Benefits:
- Vapor permeability.
- Moisture resistant.
- Ease in work.
- Quick drying.
- Great shelf life.
Performance of work
Work with a primer is divided into two stages. This is a preliminary preparation of the treated surface and the application of a primer mixture on it.
- Cooking surface. We remove dirt, dust, moisture and any oily or greasy stains and smudges, if any. There should be no cracks or chips on the surface. If necessary, the surface should be puttied.
Important: never apply a primer to dry putty!
- Thoroughly mix in the container "Concrete Contact". We calculate the consumption per m2, following the instructions, adding water if necessary.
Tip : using a spray gun, applying a primer will be much easier. Although it is also possible to apply the mixture with a brush or a paint roller.
When performing work, monitor the room temperature. It should not be lower than +5 ° C. However, too hot air is also undesirable. Since the primer is non-toxic and has no specific odor, special protective equipment will not be needed either.
- Apply a primer. It is available in pink, which is very convenient when working. All areas that have not been treated are visible, which is very important when priming large surfaces.
Once the composition is completely dry, you can begin decorating. The main thing is to prevent dusting of the primed surface, as this will cause a decrease in adhesion, and the quality of fastening of the finishing material will suffer.
Consumption of "Concrete contact" per 1m2 reaches 300 grams, which is considered the norm. You should know that after 1-2 hours the primer looks dry, although in fact it dries only 6-8 hours after application to the surface.
Specificity and Purpose
Acrylic primers are the most popular among builders. This is a mixture based on latex and acrylic. There are several varieties of primers.
Type:
- Deep penetration.
- Universal.
- Adhesive.
- Special and impregnating.
By content:
- Organically soluble - used for decoration of building facades. It is resistant to pollution, bacteria and parasites, to temperature changes and so on.
- Water soluble - used indoors.
When buying Betonocontact primers, you should definitely require a seller’s certificate of conformity, since there are many fakes.
The penetration depth of the primer can reach 10 cm, while fakes sometimes remain on the surface and do not contribute to increased adhesion of materials. Therefore, it is not worth saving, but it is better to purchase a high-quality primer "Concrete Contact", the consumption of which is even less than that of many other compounds.
When using a primer for interior decoration, you should know that it is resistant to ultraviolet radiation, as well as external primers. In addition, its use will protect the treated surface from parasites and germs. In addition, you can significantly save money, since putty and plaster lie more evenly on the primed surface.
An important property of the primer is its characteristic, such as a decrease in the absorbency of a brick, plaster, wooden or cellular concrete surface. The composition strengthens the pores of these materials. It also speaks of the cost-effectiveness and profitability of the Betonokontakt primer, the consumption of which is very economical, which makes it attractive for construction work of any complexity.
