FAQ

What is the difference between silicone and PU sealant?

Silicone sealants are ideal for glass, ceramic and non-porous surfaces with excellent UV resistance. PU (polyurethane) sealants are better for concrete and masonry joints and can be painted over. Choose based on the substrate and whether painting is required.
