Wall panel silicone sealant seals joints, edges, and panel-to-surface transitions to a watertight, professional standard, available in transparent and black finishes across Mapesil AC products. Formulated from high-performance silicone, each cartridge delivers a flexible, mould-resistant, and waterproof seal on both porous and non-porous substrates, including plaster, tile, glass, and stone, with a clean, grout-free finish that resists movement and moisture long term. Transparent silicone suits any panel colour, while black silicone pairs specifically with noir black and dark-finish Trepanel® installations for a seamless, colour-matched result.

Essential for bathrooms, shower rooms, wet rooms, kitchens, and hallways, wall panel silicone ensures every panel edge is fully sealed and installation-ready. Get expert advice and enjoy fast UK-wide delivery with Bathroom Mountain.
