KingCoat WR®
Water repellent impregnation based on water borne Silane/Siloxane.
Overview
KingCoat WR is a water based, ready for use, single component, water repellent impregnation for application on vertical or steeply sloping concrete, mineral-based natural and artificial stone, cementitious substrates, mineral plasters and mineral paints.
Applications
- KingCoat WR provides excellent water repellency and protection from weathering to vertical or steeply sloping concrete, mineral-based and artificial stone, cementitious substrates and mineral paints
- KingCoat WR can also be used for injection into walls to prevent rising damp
- KingCoat WR can be used as moisture barrier primer that is recoatable with water and solvent borne paints
Advantages
- Good penetration into substrate
- Good reduction of water and chloride intrusion
- Excellent resistance to alkalis and UV light
- Increases freeze thaw resistance
- Minimizes efflorescence
- Breathable, allows for water vapour release
- Very good resistance to dust and dirt pick-up
- STANDARDS KingCoat WR complies with the requirements of EN 1504-2 Surface Protection Systems for Hydrophobic Impregnation (H) Principles 1.1, 2.1 and 8.1
