Thompson’s Stain Block Damp Seal 250ml is a specialist interior paint designed to permanently block and seal damp stains on walls and ceilings before decorating. Its advanced stain-blocking formula prevents unsightly marks caused by water, smoke, nicotine, grease, and rust from bleeding through paint or wallpaper. The quick-drying coating creates a tough barrier that isolates stains and prepares surfaces for finishing coats, helping to achieve a clean, even appearance. Ideal for use on plaster, cement, stone, and previously painted surfaces, this compact 250ml tin is perfect for treating smaller problem areas around the home.
Application and limitations:
Thompson’s Stain Block Damp Seal 250ml is an aerosol primer designed to seal and cover interior stains such as damp marks, water stains, smoke damage, grease, and pen or crayon marks on surfaces like plaster, cement, stone, brick, and previously painted walls or ceilings. It is typically applied as a quick-drying base coat before repainting, helping prevent stains from bleeding through the final paint layer. The surface should be clean, dry, and free from loose material before spraying, and the product is usually applied in light, even coats from a short distance. However, it is important to note that this product does not treat or stop the source of damp, and it should not be used on persistently wet surfaces or areas with active water ingress. It is also not suitable for exterior use or as a finishing paint, and proper ventilation is required during application due to its solvent-based aerosol formulation.
