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.
