Ronseal One Coat Damp Seal White Paint 750ml

Permanently banish damp stains from walls and ceilings with One Coat Damp Seal. This clever solution tackles damp directly, even on slightly damp surfaces, allowing trapped moisture to escape without further damage. Once dry, it provides a perfect base for painting or wallpapering.
Before you begin, ensure the source of the damp is addressed. Good ventilation is key - open windows and doors and protect your surfaces with dust sheets. Give the sealant a thorough stir before applying with a brush or roller. For small damp patches, extend your coverage to at least 30cm beyond the affected area. Expect a touch-dry time of 2 hours, with painting or wallpapering possible after 4 hours.
Preparation is vital. Remove any existing wallpaper using a scraper and sand away loose or flaking paint. Clean the area thoroughly, eliminate mould with our 3-in-1 Mould Killer if necessary. While application to damp surfaces is possible, avoid soaking wet areas. For mould-prone areas, consider our 6 Year Anti-Mould Paint as a topcoat.
