For long, narrow gaps between window sills and tiled walls, we offer weather-resistant sealing grout. The material has elastic sealing properties, preventing rainwater or condensation from seeping into the room, while also accommodating the thermal expansion and contraction of the window frame.
Before application, old sealant residue will be cleaned, and the base layer will be treated with an anti-mildew primer before applying a high-adhesion grout. A topcoat matching the window frame color can be applied to the surface for overall harmony.
The package includes horizontal seams for two standard window sills and vertical seams on both sides, and includes a three-year waterproof warranty card.
