Thoroughly clean and repair the surface.
Remove any wallpaper or loose paint. If mould is present, use Polycell Mould Killer. Allow new plaster to dry for 7-10 days before using this product.
Mask surrounding areas to protect from overspray.
Shake well until you hear the steel pellet rattling and then continue for 1 minute more.
Spray evenly over damp patch from a distance of 20-30cm (9″-12″) until patch is covered. Shake can occasionally during use.
Allow at least 2 hours to dry before painting or wallpapering. For heavier damp patches apply a second coat for best results.
After use, invert the can and spray until nozzle is cleared to prevent clogging.
