Product Description:

CT1 is a hybrid polymer sealant and adhesive in one cartridge, bonding and sealing almost any combination of building materials. Supplied in a 290ml cartridge in brown, it is used for bonding and sealing around windows, doors, and frames, fixing trims, skirting, and panels, sealing gutters, roofing joints, and flashings, bonding stone, metal, glass, timber, and plastics, and general repair work across construction, plumbing, roofing, and DIY.

CT1 covers a wide range of jobs without a change of product. It bonds and seals on wet and damp surfaces and will even cure underwater, so outdoor repairs can go ahead without waiting for dry weather. Once cured it remains permanently flexible, moving with temperature change and vibration without cracking, and it does not shrink, so the seal holds its shape over time. It is free from solvents and isocyanates, has very little odour, and is suitable for indoor use.

The brown finish is designed to blend with timber, woodgrain uPVC, brown window and door frames, brown guttering and downpipes, and brick and stone in warmer tones, so the joint sits quietly against the surrounding material rather than standing out as a white or grey line would. The cured sealant is UV resistant and will not break down or discolour in direct sunlight. Apply with a standard sealant gun, tool the joint smooth before it skins, and clean off any excess while still wet. Once cured, CT1 can be overpainted with most paints.
