Bostik Waterstop Emergency Waterproof Coating - Grey 1kg

Details and Repair Benefits of Bostik Waterstop:

• All-Weather Application: Bonds firmly to wet surfaces and cures under pooled water, allowing you to stop urgent roof leaks during heavy downpours.
• High-Build Gap Bridging: Fills fine cracks, pinholes, and porous patches in a single coat, forming a flexible waterproof membrane that flexes with temperature shifts.
• Wide Surface Compatibility: Adheres securely to roofing felt, lead flashing, slate, zinc, masonry, corrugated sheets, and galvanised steel gutters without primer.
• Reinforced Elastic Seal: Resists cracking, shrinking, and weather erosion across freezing winters and hot summer spells, providing long-lasting joint protection.
• Straightforward Brush Application: Ready to apply straight from the tin with an ordinary paintbrush, helping you complete emergency repairs quickly and with minimal tool cleanup.
• Subtle Grey Finish: Matches standard leadwork, weathered felt, and cement mortar, ensuring neat outdoor repairs that blend in with existing roof materials.
