Protect your walls and floors from water damage with the Bostik Aquaprufe damp proofer and waterproofer. You can apply this versatile formula using a roller or brush, whether you're working on a cosy living room or an airy outdoor space. It is designed for convenience, so you can apply it straight onto a damp surface. Just two coats are needed to create a fully waterproof seal. There's no need to buy a separate primer, which means you'll save valuable time and money. 
This Bostik damp proofer is free from solvents, so there's no need to wear a mask or open windows when you're using it. It covers up to 1.25 m² per litre if you're covering a wall, and up to 2 m² if you're doing a floor. You'll end up with a flexible emulsion coating that won't crack even with heavy usage. Once cured, you can overcoat it with plaster or flooring screed.
• Can be applied to damp surfaces
• Must be over-coated with plaster or flooring screed
• Does not need a primer
• Suitable for interior and exterior use
• Solvent-free
• Perfect for preventing water ingress in walls and floors
