Paint Problem

May 30, 2020


Hard to see, but the paint on this wall is crackling. This is most likely because there are unstable and incompatible layers of paint underneath.

In an old house like this (1940’s), there will have been many treatments to the walls over the years. Original oil-based paint, covered by latex paint, gloss paint, dust, more colors and layers of paint. And virtually never does the workman prep the walls properly.

Latex doesn’t like to stick to oil, and most paints don’t like to stick to gloss, plus other factors. So what happens is that all these disparate layers rebel, and sometimes you end up with flaking or peeling.

If wallpaper is applied on top of these unstable walls, when it dries and pulls taught and puts tension on the wall surface, there is the potential for these layers to give way, and you can end up with a curled seam, under which are layers of delaminated wall.
