Mildew, Bleach, KILZ

June 7, 2018


Whooah! I stripped off wallpaper from this wall around a window in a home that had some water damage from Hurricane Harvey, to find this black powdery stuff – mildew. You don’t want to put wallpaper over a wall that has mildew, because the black stuff will continue to grow. And because it’s chalky / powdery, it the wallpaper will not stick to it. And it will also work its way through the wallpaper and create a stain on the surface.

I use bleach to kill the mildew and remove it from the wall. Once dry, I use KILZ Original oil-based stain blocker to seal the surface. In this case, I also skim-coated the wall, to make it nice and smooth. I will follow that with a coat of Gardz, a penetrating sealer that is also a good product to hang wallpaper on.
