For machine application, the concrete contact can be brought to a spraying consistency by adding just a little water (where necessary).
Avoid contact with skin and eyes. In case of contact, rinse immediately with water. Wear safety goggles when working overhead. Store the container in a cool, dry and frost-free place. Keep the container tightly closed.

Datasheets(X)
Ready-to-use primer for smooth mineral surfaces. Concrete contact is a water-based, solvent-free primer for improving the adhesion of gypsum, cement and lime-based fillers and plasters on smooth, non-absorbent or low-absorbent mineral surfaces (especially concrete). Suitable for indoor and outdoor use.
Concrete contact is particularly suitable for smooth in-situ concrete or solid slab floors made of prefabricated components as well as for smoothed pre-cast concrete surfaces and expandable polystyrene hard foam boards. Surfaces that are already primed can be easily detected by the reddish colour of the product.
The surface must be load-bearing, dry and free from loose particles and release agents (formwork oil, post-treatment compounds, etc.). Moisture absorption and moisture migration through the substrate must be avoided.
Stir the concrete contact well before use and also after longer breaks, and apply with a roller, brush, wide brush or a suitable spraying device. For machine application, ensure suitable spraying consistency by adding a little water. For manual application, apply crosswise wet-on-wet. Protect areas not to be primed from splashes. The primed surface must be completely dry before applying plaster.
