Waterproofing Primer - the cornerstone for quality of repair baths

Why is it necessary?

Primer - a white opaque liquid that after drying, penetrates into the material and forms a film inside and out.In this way, there is the strengthening of the surface than the extended service life.In addition, it provides good adhesion between the top surface and the deposition material and constitutes the first layer of the multilayer coating, so it demands fairly high.Depending on the application, various types of the mixture.

water repellent coating, as mentioned above, is used in rooms with high humidity.Apply it on porous surfaces such as stone, brick, drywall, concrete, plaster, and so on.The aim of this treatment is to protect these materials from the damaging effects of moisture and wet inside and outside the premises.In addition, the water-repellent coating enhances the properties of concrete and cement mixtures.

Important!Use mixtures which can not withstand moisture, it is impractical, since they are no useful properties are not surface.

Kinds material

primer bath is divided into two groups:

• adhesive;
• firming.

first necessary in order to improve the adhesion between the layers of finish.Apply it on painted or plastered surfaces.Depending on what material is used as a basis mixture there alkyd, acrylic, minerals, phenolics, polystyrene primer.In the premises, you can only use the first three types.

Reinforcing mixture used to launch a surface treatment in order to strengthen and align it before applying the next layer.After priming topsheet material is glued to a depth of three centimeters.When using primers deep penetration of an adhesive layer can grow up to 10 centimeters.Use this mixture before applying thick coatings - artistic plaster or tile adhesive.

Important!Before buying a mixture with water-repellent properties is required to carefully read the information on the composition and conditions of use on the packaging.

waterproofing primer, or that it should be aware of?

Primer water-resistant must be placed on pre-prepared surface.For this last cleaned, degreased and skins.All major cracks should be eliminated with the help of plaster.After applying the mixture it water-repellent properties develop within 12 hours.If you need to add the primer mixes, it should be remembered that its share should not exceed 4% of the total weight of the solution.Before using the required composition mix thoroughly.It can be applied by spray, roller or brush in several layers at temperatures below 5 degrees Celsius.

Primer is flammable and explosive substances, so it should be kept away from sources of ignition.It is also prohibited to mix it with other types of compounds, solvents and diluents.Working with it, you should use personal protective equipment for the respiratory system, eyes and hands.Store substance is necessary to securely closed containers at a temperature not below 5 degrees, even though it is able to withstand up to five freeze-thaw cycles, after which will fully restore its water repellency.

Important!In the case of freezing the mixture should be thawed at room temperature for one day.
