Overview
KingCoat Primer S is a penetrating hydrophobic silane/ siloxane based primer. It is used as a primer for KingCoat S 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.

Very good reduction of water and chloride intrusion.
Breathable, allows for water vapour release.
Why use it
Highly durable and tough wearing marking paint.
Quick drying easy to apply (one component).
