Marker Bleeds Through Wallpaper – Prevention

February 19, 2020


Whoops! Whoever hung the mirror used an ink marker to indicate where the hooks would go. Ink bleeds through wallpaper – and paint and other substances, too.

I had not seen the stains on the painted wall before I started to smooth the walls. But, as you can see, in just a few hours, it worked its way through my rough skim-float, then after this was sanded and primed, the ink bled through again.

KILZ Original oil-based primer / sealer / stain blocker is my solution for this. I don’t trust any latex or water-borne products.

No “after” picture, but I daubed a fingertip full of KILZ on top of each green spot, and am confident that the stain will not come through the new wallpaper.

Air Bubbles from Latex Paint

June 13, 2018

The walls had a light texture covered with latex paint, so I skim floated over the walls to smooth them. When the wet smoothing compound got onto the wall, the latex paint absorbed moisture, expanded, and created these bubbles. It’s called “off gassing.”

After the mud dried and was sanded, most of the bubbles disappeared, but some rings were still visible. When I primed with Gardz, a water-borne penetrating sealer, many of the bubbles raised their heads again.

I will have to see if they dry flat over night, or if I will have to use my putty knife to knock them off in the morning. I don’t want bumps showing under the new wallpaper!
