Thompsons Damp Seal is a high performance interior coating which permanently covers damp, water and other household stains. The micro-porous, breathable formula can be applied directly to damp walls and ceilings, allowing trapped moisture to evaporate over time and preventing paint flaking or wallpaper peeling.
