Product Description Need to fill or seal an expansion joint between two different materials? Everbuild Tecnic 825 Silicone Sealant is a low modulus formula designed with a long skinning time to give you a longer tooling time and the flexibility you need to finish the job. It's neutral cure and odourless, so you can feel confident using it indoors, and it's weatherproof for external use, as well. The adhesion is top tier as it suits both porous and non-porous surfaces, including brick, PVCu, glass and more.
