Potassium Silicate Primer and Water Glass Sealer for Masonry

Mineral primer for absorbent masonry

This potassium water glass is a pure mineral binder and ready-to-use potassium silicate solution. It strengthens mineral substrates, reduces absorbency and prepares surfaces for later wallpapering and painting work.

For sealing brickwork and mineral impregnation, it can be used on masonry, cellar walls, concrete, natural stone and sanding plaster. It also serves as a primer for silicate paints and lime paints.

Breathable silicification

The primer works without film formation through silicification. It is weather- and moisture-resistant, very breathable and supports good adhesion on mineral substrates.

Areas of use

✓ Sealing and impregnating masonry and concrete
✓ Cellar walls, natural stone and sanding plaster
✓ Primer for silicate paints and lime paints
✓ Indoor and outdoor use

Product properties

✓ Pure mineral binder
✓ Ready-to-use potassium silicate solution
✓ Consolidates and impregnates substrates
✓ Reduces substrate absorbency
✓ Weather- and moisture-resistant, vapour-open

Application

The substrate must be dry, free from dust and grease, and free from old coatings. Apply with a brush, roller or suitable spraying device and avoid inhaling spray mist. Determine consumption by test area depending on absorbency. Clean tools with water immediately after use.
