Drybase Liquid-Applied DPM is a single-pack barrier coating that is supplied ready to use. It is available in black or white with a consistency similar to that of thick emulsion paint.
Once applied, the product cures to form a membrane that is flexible and elastic. Drybase Liquid-Applied DPM is water-based and can be applied to damp substrates by brush, roller, or spray. The applied product is typically touch-dry in one hour.
Once cured Drybase Liquid-Applied DPM provides a barrier to damp and ground gases (including radon, carbon dioxide, and methane).
All contact surfaces must be sound, clean and smooth with a trowelled or brushed finish. Any masonry should be flush-pointed and defects in existing surfaces made good. Remove any laitance, dust, loose material or surface water.
- Stir well before use.
- Apply at least two coats with each at 0.55 litres/m2 in order to comply with CP102:1973, Code of Practice for the Protection of Buildings against Water from the Ground.
- Always allow the first coat to become touch dry (typically one hour) before applying a second coat at right angles to the first. The first coat should not be allowed to dry for more than 24 hours before applying the second coat.
Black Drybase will go on as dark blue, and dry to black once it's cured. If the colour remains blue, then this is an indication that further drying is required.
Application of the membrane should not be undertaken if rain is expected before the coating can dry. Do not apply if the background or air temperature is 7°C or lower.
