Detailed Product Description

A quartz-sand bonding agent (Betokontakt) designed to transform extremely smooth and non-absorbent surfaces (like exposed concrete and glazed tiles) into rough, high-grip surfaces ready for plastering or tiling.
Heavy-duty acrylic polymer dispersion reinforced with carefully selected quartz sand grains to maximize surface roughness.
Clean the surface thoroughly, removing old flaky paint or loose materials. When applying over existing glazed tiles, degrease completely.
Ready to use. Must be stirred vigorously in the bucket before application to ensure uniform distribution of the quartz grains.
Apply an even coat using a roller or brush. Do not dilute. Wait at least 12 hours for the layer to dry completely into a hard, rough surface before proceeding with plaster or adhesive.
Non-toxic and non-flammable. Clean tools with water immediately after use. Avoid eye contact; if contact occurs, rinse with clean water.
Store in original unopened containers at temperatures between +5°C and +35°C. Protect from direct sunlight and frost. Shelf life is 12 months.

Frequently asked questions

What is EuroFix Contact Primer (Betokontakt) used for?

A ready-to-use contact primer loaded with quartz-sand grains, applied to smooth, non-absorbent concrete surfaces (formwork-cast concrete, precast columns and soffits) to create a rough, keyed surface that provides excellent mechanical anchorage for subsequent plaster and render. It eliminates the laborious hand-scabbling (hammer-chipping) normally needed to roughen smooth surfaces.
