Stains from Wood / Furniture Polish Bleed Through Wallpaper

November 24, 2018


Originally, the walls in this West U. living room were smooth and painted. I didn’t notice anything or any stains when I started priming the walls. But almost immediately after the wallpaper primer was applied, I saw some brown stains work their way through the primer. The wall paint must have sealed them adequately, or perhaps I just had not noticed them, but something about the wallpaper primer activated the stains and brought them to the surface.

A large, old (antique) piece of wooden furniture had sat against this wall, and probably leaned against it. I figure the stains are from either wood sap (yes, even after decades) or from oily furniture polish that came into contact with the wall.

Either way, these stains could work their way through the new wallpaper, just as they had worked their way through the primer. They needed to be sealed with a stain blocker.

Many people use a shellac-based stain blocker, like BIN by Zinsser. But I like KILZ Original, the oil-based version (not the newer water-borne).

Once I applied the KILZ to the stains, they did not reappear. Now I am good to go to get the paper up!

Wallpaper on a Window Valance

June 12, 2018


I hung a beautiful grasscloth in the West U. living room of this empty-nester couple a month ago. They were putting the room back together, including hanging the curtains. This window valance had been covered with padded fabric which matched the drapes. Since the drapes are being changed, the valance no longer worked. The couple thought that the valance would look better covered in the same material as the walls.

So … I brought the valance home, along with some left over wallpaper scraps, and covered it.

The photo is deceptive – the thing is about 7′-8′ long. At first I thought I could take it to work with me and do it while I was waiting for primer to dry, for instance. But it’s way too big and loppy to haul into someone else’s home and, would, of course, take more time than anticipated.

So it sat in my garage for a couple of weeks, until I finally found a spare moment (three hours, actually) to pull out my tools, set up my table, get out the measuring tape, and slap some paste on that puppy.

The homeowner had removed the upholstery and the padding, and hammered the staples down as flat as possible. Then I sealed the wood with oil-based KILZ Original stain blocker, to prevent any wood sap from bleeding through the wallpaper. Since wallpaper paste won’t stick to most oil-based products I followed that with a coat of wallpaper primer (Ultra Prime, Pro 977 by Roman’s). On the driveway under the June Houston sun, that didn’t take long to dry. 🙂

Then some careful measuring to get panels of equal width, pasting, and applying the grasscloth to the wooden frame. I used a special “super glue for wallpaper” (clear silicone caulk 🙂 ) for the edges, to be sure the grasscloth would be able to grip on to the uneven and rough wooden surfaces.

I was pleased with the way it turned out. And I know the homeowners will be happy to get the valance up on the wall, their curtains up, and their room put back together and ready to enjoy.

You Can’t Just Slap Wallpaper on Top of Paneling

May 5, 2018

Today I am hanging grasscloth on wood paneling. You can’t just slap wallpaper on top of wooden paneling. Even old wood has resins, and these can bleed through wallpaper. So the paneling had to be treated with a stain blocker. I used KILZ Original (their water-based version is not as dependable), a wonderful oil-based primer that seals off a multitude of problems – wood sap, water stains, tobacco, rust, blood, grease, ink, etc.

In addition, the grooves in the paneling had to be filled in, to prevent the wallpaper from drying, pulling taught, and sucking down into the grooves, revealing a visible vertical line. So once the KILZ was dry, I skim floated the paneling, both to bridge the grooves, and to fill in the light wood grain, and, to add a second buffer layer to seal off any wood resins. This was sanded smooth and followed by a coat of a penetrating primer called Gardz.
