The Clear Liquid Builders Don’t Talk About.
This invisible waterproof coating seeps deep into hairline cracks and porous surfaces, quietly sealing the spots where leaks usually start. Just clean the area, brush it on and let it cure – it dries crystal clear, helps block rain and damp on walls, roofs and window sills, and keeps ugly stains, mould and peeling paint from ever appearing. One small DIY job today can save you from a noisy, dusty and expensive contractor visit tomorrow.
Waterproof Protection on Most Surfaces
Our Clear Polyurethane Waterproof Coating creates a tough, invisible barrier that helps stop water from seeping into roofs, walls, floors, balconies and more. Just brush it on and let it dry – it self-levels into a seamless film that seals small cracks and gaps, helping prevent leaks, damp spots and mould without changing the look of your wood, tile, stone or concrete. Easy DIY application with no contractor needed, and strong resistance to UV, heat and weather for long-lasting protection.
