Description

Field of Application

 Repairing and renewing views of building and all pre-cast and cast in place concrete structures,
Repairing damages such as cracks, unevenness, ruggedness, breaks and flaws on surface in all kinds of concrete structures,
Repairing cement places, mosaics and units,
Repairing interior and exterior sub-floors prior to placing new cover,
Repairing and flattening spongy surfaces,
Usable for surfaces exposed to direct water,
In hydraulic structures,

Properties and Effects

 Ease of use,
Not requiring additional additives to increase bond strength,
Providing adequate tensile strength in repairing concrete facades,
Sufficiently adhesive to all kinds of cement bases,
No shrinkage and creeping,
Highly resistant to thawing-freezing cycles and destroying environmental factors,

Dosage

Depending on the quantity of pore and ruggedness of the target surface, use approximately 1 to 1.5 Kg of BC69 per square meter with 1 mm thicknes

Instruction for use

a) Base preparation:
The base surface should be completely clean and free from oil and 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 BC69 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 6 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
