Thompsons Water Seal 1Ltr

Thompson's Water Seal is a high-performance waterproofing solution formulated with a unique micro-silicone emulsion. This advanced technology is designed to penetrate deep into the pores of mineral substrates, creating an invisible, breathable barrier that effectively prevents liquid ingress while allowing internal moisture to escape.

Unlike traditional sealants that require bone-dry conditions, this formula is engineered for efficiency. It can be applied directly onto damp surfaces, making it an ideal choice for the unpredictable British weather. Once applied, it begins to work immediately, providing a long-lasting waterproof seal within just a few hours.
