"Bostik Water Seal is a high performance waterproofer for trade use, that penetrates deep below the surface to provide a water resistant barrier on porous exterior surfaces. It is suitable for concrete, brick, stone, slate, terracotta, render and timber.The surface remains permeable to water vapour, allowing it to ‘breathe’, preventing water being trapped. Water Seal is transparent and should not alter the appearance of the treated surface. Some surfaces may darken very slightly, so always carry out a test on a small area before full application. Water Seal also helps to prevent condensation, efflorescence and frost damage. Fast drying, exterior masonry and wood protector. Prevents water penetration in a single coat. Protects against rain, damp and frost. Increases life of most building materials."

"Bostik Feltfix Bituminous Roof Felt Adhesive is a cold applied solvent-based bituminous adhesive. It has high initial grab for bonding bituminous roofing felts to asphalt, felt, metal, timber and concrete.

"Bostik Integral Waterproofer is a liquid additive that provides long-term water protection to mortar, non-structural concrete and rendering. It is an alkaline soap of mixed fatty acids, which reacts chemically with cement to form hydrophobic salts, which reduce water penetration.Bostik Integral Waterproofer helps reduce efflorescence and lime bloom by restricting moisture movement and helps reduce crazing in rich mixtures by controlling the rate of evaporation.It waterproofs and plasticises mortar for external or basement renderings, pointing and in swimming pools, sewers and tank linings as part of the overall waterproofing system specification. It will not corrode reinforcing metalwork, but is not suitable for use in structural concrete. Waterproofer and plasticiser for mortar. Ideal for renders. Reduces efflorescence and crazing."
