KingCoat Primer A®
Silane/siloxane based hydrophobic primer.
Overview
KingCoat Primer A is a penetrating hydrophobic silane/ siloxane based primer. It is used as a primer for KingCoat acrylic based protective coating. When applied, it reacts with concrete and masonry surfaces producing a clear hydrophobic barrier that prevents the passage of water and hence protects exposed reinforced concrete structures from attack by chloride ions.
Advantages
- Deep penetration into substrate
- Very good reduction of water and chloride intrusion
- Breathable, allows for water vapour release
