Primers and impregnations  

Structural. For smooth surfaces/concrete – contact.
This primer is used as a primer for smooth concrete surfaces before applying façade materials, and it is particularly suitable as a bonding bridge while gluing new ceramic tiles on old ones. The application of this primer produces a relatively rough substrate (contains particles of the size of up to 700 microns) enabling a better-quality adhesion for material such as concrete paint, adhesive, façade and similar.

Substrate has to be hard, dry, free of dust, grease and other impurities. Cement and cement-lime mortar should dry for at least 1 day for each mm of thickness (T=20°C, rel. humidity 65%), whereas concrete surfaces should dry for at least one month. Uneven surfaces should be evened out using appropriate materials. Hot water jet or steam wash is recommended to perform additional cleaning. Surfaces contaminated with algae and fungi should be remediated before the primer and finishing material are applied. (treat the entire wall surface with ALGOSTOP, not only the spots with algae and fungi).

Before use (and if necessary, also during use) the material should be thoroughly mixed and, if necessary, diluted with water up to 5%. It is applied using trowel with long fibres or brush in one coat 24 hours before the next material is applied (T=200C, rel. humidity 65%). Optimal air and wall temperatures during work and drying should be from + 50C up to + 300C, and relative humidity should be under 80%. Use protective sheeting for scaffolds during application. Do not work in wind, rain, fog or in direct sun. Wash tools with water immediately after use. Primer in its original, well sealed and undamaged packaging that is not diluted with water may be kept for a subsequent use.
