No shrinkage or cracks,
Increasing tensile resistance during repair operation,
Increasing durability of concrete in thawing-freezing cycles.
Its thermal expansion is equal to concrete’s,
BC68 and concrete are very similar in color,
Ease of use.

Depending on the quantity of pore and ruggedness of the target surface, use approximately 1.5 Kg of BC68 per square meter with 1 mm thickness

a) Base preparation:
The base surface should be completely clean and free from dirt. To prepare base, use BC72. To increase the concrete bond strength to cement structures, moisten and roughen the base surface
b) Application
The powder shall be mixed with water at the rate of 30 to 40% by weight of BC68 and mix well to obtain a uniform pasty mixture. The prepared paste must be allowed to elapse for 15 minutes before use. To make a better mix use Beton Chimie mixer. The mortar can be applied in 5 mm thickness for each layer. To increase the thickness of layers apply the mixture in phases. Thickness of up to 20 mm is allowed. Use the mortar within 30 minutes
