BK-Beton Kontakt

Structural primer for smooth surfaces

USE
CHARACTERISTICS
PACKAGE

Structural primer designed to increase and even out the adhesion of poorly absorbent, smooth, high-density substrates prior to rendering with lime-cement and gypsum-lime mortars. BK-BetonKontakt is especially recommended for smooth concrete surfaces as well as prefabricated concrete surfaces. It is also used as a primer in tile installation systems.

Preparation and application :
The substrate to which BK-BetonKontakt is applied must be solid, dry, and dust-free. Prior to use, the product must be thoroughly mixed and homogenized, and if needed, diluted with water in a small amount, up to a maximum of 1% (0.06 liters of water for 6 kg of product; 0.20 liters of water for 20 kg of product). The primer is applied with a brush or a long-hair roller in one coat. Machine application with appropriate equipment is also possible. The required drying time before applying the render is a minimum of 4 hours. The air and substrate temperatures during installation should be in the range from +5 °C to +30 °C. Do not work in direct sunlight, rain or strong wind. High humidity and low temperatures can significantly extend the drying time.
Shelf life and storage :
Up to 18 months in original sealed packaging. Store at temperatures from +5°C to +25°C, protected from direct sunlight and frost.
Consumption :
About 0,5 kg/m².
