HB42 Simply Ultimate Silicone - White - 290ml - Box of 12

HB42 Ultimate Silicone – White, Box of 12 Cartridges

HB42 Ultimate Silicone in White gives a premium, high-gloss, professional finish to bathrooms and wet rooms. It's just as capable beyond sanitary work too — think kitchens, stone floors, granite and marble worktops, external brickwork, glazing, and connection and expansion joints. This box contains 12 cartridges.

This is an acetoxy-free, neutral cure silicone, so it won't stain delicate stone, granite or marble surfaces, and it's non-corrosive on metals — making it a safe option across a broad range of finishes. The crisp white finish gives clean, consistent lines that match white sanitaryware, tiling and trim. It also skins in just 8–10 minutes, so it's quick to tool and doesn't hang around.
