How to use
Surface preparation
Surface preparation is very important to get the highest performance of KingProof B100. Any surface to be coated must be clean, sound and free of oil or grease. Any oil or grease contamination should be removed with a chemical degreaser. All holes should be filled with a suitable cementitious mortar before application of KingProof B100.
Primer Coat
There is generally no need for primer coat. Dusty surfaces should be primed with a coat of KingProof B100, diluted with an equal quantity of cool, clean water and allowed to dry.
Application
It is recommended that two coats of KingProof B100 be applied. The second coat should be applied at a right angle to the first coat. Allow a minimum of 3 hours between coats. Stir well before use. KingProof B100 may be applied by brush, broom or squeegee.
Cleaning
Tools and equipment can be cleaned with water when still wet.
Dried KingProof B100 may be removed with KINGKRETE Solvent.
Coverage, packaging and storage
Coverage
3 - 5 m²/litre, depending on surface roughness.
Packaging
KingProof B100 is available in 18 and 200 litre drums.
Storage
Shelf life is 1 year when stored under cover, out of direct sunlight and protected from extremes of temperature.
