Overview

KingProof B400 is a dark brown emulsified bitumen liquid reinforced with latex rubber, formulated from selected raw materials to form a high build elastomeric waterproof and protective coating for concrete and masonry.

Applications

KingProof B400 provides a waterproofing and protective coating for:
Retaining walls
Shaded or tiled roofs
Underground concrete foundations
Wet floor areas such as bathrooms and kitchens
Where minor live cracks may occur in concrete substrates, KingProof B400 will bridge such minor cracks
Basement walls
Concrete slabs
Suitable for use as curing compound for fresh concrete
KingProof B400 can be used as protective coating for normal and galvanized steel plates

Advantages

Elastomeric will bridge minor cracks which may occur in concrete substrates
Resists attack by chloride and sulphate ions present in ground water
Single component
Easily applied by brush, roller, broom or squeegee
Economical
Solvent free, non flammable
Asbestos free
Rot resistant
STANDARDS KingProof B400 complies with ASTM D1227, Type III, Class 1
KingProof B400 complies with ASTM C309 as a curing compound when applied with two coats at a rate of 4 m2/litre per coat
KingProof B400 complies with ASTM D3747, Type I and II
