Primer Choices

December 12, 2019


Today I was priming the backs of some bar cabinets. My preferred primer, Roman’s Ultra Prime Pro 977, which usually sticks to anything, was beading up and sweating off of the Formica surface. Even if it dried, it would leave beads and bumps under the wallpaper. I had to take a paper towel and wipe it all off.

Luckily, I had some Zinsser 123 in my van. This stuff sticks to just about anything. It rolled on with no problems.

It’s OK to hang wallpaper over 123, but I prefer to hang on a product made specifically for wallpaper. So, once the 123 was dry (it dries quickly, and for good measure, I set a fan blowing on it), I rolled on a coat of Ultra Prime.

This is all very timely, because I was looking at that can of 123 just the other day, which was bought exactly a year ago and which I virtually never use, and was about to toss it out. I’m glad I kept it.

I’m Scared Of This Blue Dot

I am going to hang grasscloth in this large master bedroom in the River Oaks neighborhood of Houston. To smooth the textured walls, I skim-floated the walls with “mud” (joint compound). As I was sanding the compound smooth, I discovered this small blue spot. It might be ink. Or maybe some cleaning solution, or a cosmetic or perfume, or some other agent. SOMEthing was on the wall before I applied the smoothing compound, and bled through.

Whatever it is, it worked its way through the smoothing compound and up onto the wall surface. If a substance works its way through the wall surfaces, you can be sure that it will also work its way through the new wallpaper.

To prevent this, there are a couple of options. One is to cover the area with a stain-blocking sealer. I love oil-based KILZ Original. Another product is BIN by Zinsser, or 123 also by Zinsser.

But in this case, since it is just a tiny dot, I decided to use a Stanley knife to dig out the stain. Gone. Done. No worries about anything bleeding through the wallpaper.

If the new wallpaper had a smooth surface, I would patch over the hole and sand the area smooth, and spot-prime. But since the new wallpaper is a rough-textured grasscloth, this 1/4″ dent in the wall will not be noticeable, so I’m going to leave it as it is. Tomorrow, before hanging paper, I will double check to be sure no additional blue stain has worked its way out from hiding.
