MASTIC & SILICONE SEALANT SPECIALISTS

Rainbow Coloured Silicone Sealants are high-performance frame sealants designed to accommodate a wide variety of building and construction joint applications. Their versatility makes them suitable for sealing glazing units in materials such as powder-coated aluminium, ceramic, PVC, painted wood, metal, and brickwork.

Formulated to handle high-movement joints, they are particularly effective between differing substrates, including timber frame constructions. The sealants provide excellent adhesion to both porous surfaces—such as brick, block, and wood—and non-porous materials including ceramic tiles and glass.

With built-in anti-mould properties, they are ideal for use in high-humidity environments such as bathrooms, showers, wet rooms, and kitchens. In addition, they can be used as an adhesive for cosmetic trims in sanitary, bathroom, and cleanroom settings, while also delivering reliable adhesion around internal window and door frames, particularly onto emulsion-painted surfaces.
