Overview

KingProof B20 is a dark brown emulsified bitumen liquid reinforced with rubber, formulated from selected raw materials to form a high build elastomeric water proof and protective coating for concrete and masonry.

Applications

KingProof B20 provides a water proofing and protective coating for:
Retaining Walls
Shaded or tiled roofs
Underground concrete foundations
Wet floor areas such as bathrooms and kitchens
Where minor live crakes may occur in concrete substrates, KingProof B20 will bridge such minor cracks
Basement walls
Concrete slabs

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 B20 complies with ASTM D1227 Type II, Class 1
KingProof B20 complies with ASTM C309 as a curing compound when applied with two coats at a rate of 4 m2/litre per coat
