Proof That Primer Protects the Wall

December 8, 2021

This is the wall anchor that holds the toilet paper bracket. When I hung wallpaper in this powder room a few years ago, to save time and allow more time for the primer to dry, I left the towel bars and other hardware in place and primed around them. Then, as the primer was drying, I removed them.

In this photo, I have stripped off the wallpaper, using water to reactivate the paste and loosen the paper backing. The primed area of the walls held up beautifully.

But as you can see in this photo, the area that was not protected by the primer allowed the water to penetrate into the surface. You can see the original builder’s grade paint delaminating from the wall.
