Setup, Compatibility & Care
Surface Preparation: Before application, ensure the wall or ceiling surface is clean, dry, and free from loose particles, mould, or mildew. Remove any existing wallpaper or loose paint. For a smooth finish, fill any cracks or holes with an appropriate filler, such as Polycell Polyfilla, and sand down the area. Mask off surrounding surfaces to protect them from overspray.
Compatibility: Polycell Damp Seal is suitable for use on plaster, cement, stone, and brick surfaces. It is intended for indoor use only and should not be used where condensation is a problem, at ground level, or on surfaces with efflorescent salts.
Application: Shake the can vigorously until the steel pellet rattles, then continue shaking for one minute. Hold the can upright and spray evenly over the damp patch from a distance of 20-30cm. Allow the first coat to dry fully. For more significant damp patches, a second coat may be beneficial. Allow at least 24 hours between coats and before decorating.
Tool Cleaning: To prevent the nozzle from clogging, immediately after use, invert the can and spray for a few seconds until only clear propellant emerges. Store the can in a cool, dry place, away from extreme temperatures and frost.
