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.

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.\n• Can be applied to damp surfaces\n• Must be over-coated with plaster or flooring screed\n• Does not need a primer\n• Suitable for interior and exterior use\n• Solvent-free\n• Perfect for preventing water ingress in walls and floors

Effective barrier -applied externally and internally to prevent rainwater seepage between concrete garage side and concrete deck. Brushes easily - less sure about brush cleaning instructions!

Excellent stuff, great for creating a DPC on concrete floors that don’t have DPM already installed. Also used on brick walls, where waterproofing is required. Just brush on.

Goes on well

Should make clearer Product should be applied to flat surface and requires 50mm screed to work as DPM/DPC. that said, I used as DPM layer on very uneven concrete base (Having removed cement screed that had breached dpc in old outhouse/wc. Applied sprinkling of dry sand before applying 20 - 40mm self-levelling screed (mapei) before applying tiles. Screed bone dry and no rising damp issues. Use cheap brush as almost impossible to clean off. No bitumen/bad chemical odours flexes better than bitumen/resin/acrylic being rubber bitumen mix. Goes on like treacle, dries jet black so astetically pleasing under dpc level.

Creates a rubber like seal. However, is susceptible to mould growth.

Just paint it on and leave to dry

Used it to cost the back of plasterboard before re-plastering a sloping ceiling where there has been an intermittent leak. Think the leak is fixed but added this just in case.
