A highly flexible, water repellent, general purpose sealant that has excellent adhesion to all surfaces, even when damp. This product can be over-painted with certain paints and it will not crack or slump or become brittle with age. Suitable for use on brick, concrete, stone, all metals, painted or bare wood, glass, vinyl and most plastics. Being rubber based this sealant is compatible with bitumen, asphalt and roofing felt (all Rain-Mate colours will adhere to bitumen and asphalt but we only recommend black for this purpose as unsightly discoloration can occur with white and clear) and is ideal for roof repairs in damp conditions (remove any standing water before application). Can also be used to seal doors, windows, roofs, cladding and vehicle bodies.
