DON’T Write in INK On the Walls!

January 11, 2019


Today I was prepping a room in a home in Kingwood (far northeast Houston) that was damaged during the flooding from Hurricane Harvey in 2017. Look at what some contractor did – he went and wrote on the wall in INK!

Most EVERY workman of any type knows that you NEVER write on walls with ink – nor crayon, Sharpie, lipstick, or other.

Reason being, that these substances will work their way through wallpaper (and paint, joint compound, and other substances, too). It may happen quickly, or it may take a few years, but these materials will show themselves eventually, as ghost-like stains on the wall.

Other things will cause staining, too, like blood, water, rust, oil, grease, food, wood sap (knot holes), and more.

Luckily, there are dependable stain blockers on the market that can be brushed on. I like oil-based KILZ Original, but shellac-based BIN is good, too. Water-based products don’t perform as well, no matter what the label or salesman says.

I like to be extra sure, so, when I can, as in this case, I will take a knife and cut around the stain, then dig into the drywall and remove the top layer, taking the ink with it. This way it is GONE, not just covered up.

Of course, the remaining exposed / torn drywall needs to be sealed, skimmed over, sanded smooth, and then prepped for paint or wallpaper.

But all that is worth it, when you can be assured that no stains will bleed through the finish coat.

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.

Don’t Mark The Walls With Ink

The two holes in the wall are from picture hooks. See the little “X” under the holes? That’s from whoever was hanging the hooks. He was measuring and marking the wall, so he would know where to hammer in the nails for the hooks.

The only problem is that he used a ball point ink pen to make his marks. Ink is bad because, diminutive as this “X” is, it will bleed through wallpaper. It will bleed through paint and other materials, too.

Other substances that can bleed through wallpaper include water stains, oil, grease, wax (crayon), tar / tobacco, blood, rust, and more.

There are special stain-blocking sealers that can be used to cover these types of marks. KILZ Original is one that I like, and BIN is another.

Since this was tiny, and since I was skim-floating the wall to smooth it anyway, I just used a putty knife to dig the mark out of the wall. Gone! That way I don’t have to worry if a stain blocker will do its job sufficiently. Then I skimmed over the gouge with joint compound to smooth the surface.
