CT1 Multipurpose Waterproof Construction Adhesive & Sealant is the ultimate all-in-one solution for professional sealing, bonding and construction applications. Available in six versatile colours, include black, brown, and grey, CT1 combines exceptional adhesive strength with superior sealing performance, making it the preferred choice for builders, tradespeople and DIY enthusiasts alike.
Designed using advanced hybrid polymer technology, CT1 delivers a permanent, high-strength bond on virtually any material without the need for additional fixings. Whether you're working with metal, glass, mirrors, fibreglass, plastics, stone, concrete, wood or ceramics, CT1 creates a durable bond that withstands extreme loads, pressure and tensile strain. Unlike conventional adhesives and sealants, it contains no solvents and remains flexible after curing, helping to prevent cracking and shrinkage over time.
One of CT1's most impressive features is its ability to perform in challenging conditions. It can be applied directly to wet surfaces and even underwater, making it ideal for emergency repairs, marine applications and outdoor projects where moisture is present. As a waterproof sealant, it provides a long-lasting seal around baths, showers, windows, doors, roofs, gutters and countless other applications, helping to protect against water ingress and weather damage.
Successfully bonds to metals (including lead), glass, mirrors, all woods, polystyrene, plastics (excluding polypropylene), fibreglass, tiles, concrete, most stones (without staining), most synthetic materials.
