Seal leaks and cracks with one clear, invisible coat

Stop drips and seepage before they spread. This transparent waterproof paste brushes on like a clear gel and cures into a tough, flexible film that locks water out of walls, roofs, gutters, pipe joints, window frames and tile gaps. It dries colourless, so the repair disappears into the surface and your home stays looking clean and finished.

Brushing on transparent waterproof sealant

Why you'll love it

Completely invisible finish – cures clear with no trace, no yellowing and no ugly patches.
Powerful waterproof barrier – forms a dense, flexible seal that blocks rain, damp and standing water.
Sticks to almost anything – bonds to concrete, brick, metal, wood, glass, ceramic and PVC.
Brush-on simplicity – just clean, coat and let it set, no primer or special tools needed.
Long-lasting protection – resists cracking, weather and temperature swings season after season.
