Almost every room in my house has a Wall paper trim, that the previous owners have painted over, I was wondering how to remove it.
This is so not a fun job!!!!!!
First, go to a wallpaper store, and get a perferation tool called a tiger claw. It has a roller in it that you just roll all over the exsisting wallpaper to perferate the paper!
Next, ask them for liquid wallpaper stripper. I’d get a few bottles( 3 or 4)!! You mix it with water. In your case, mix it 25% water to 75% stripper. Wear gloves and a mask. the stuff can be quite toxic.
You’ll need a 6" wide and 3" wide putty knife.
OK…take one section at a time. Roll the tiger claw over the wallpaper, until you see a whole bunch of holes all over the paper! Now, take a spray bottle and spray the stripper mix onto the wal, making sure to soak it real good! The paint is going to act as a blocker, but if you put a TON of holes in the wallpaper, the stripper will find a way in!
Make sure you have lots of plastic on the floor, and tarps, because this is gonna be a bit messy!
After you spray an area, move to another area, and do the same thing!
Take the 3" knife, and find an edge, and start working the knife under the wallpaper. Even if you can get the top layer of wallpaper off, you can respray the wallpaper left. It is totally going to soak up the stripper. AS it does, use the 6" knife to scrape away the remaining paper.
Once you clear one wall, take another sprayer and spray the wall with plain water, and wipe it down with a sponge. ring out the sponge often. You want it damp, not sopping wet.
This will be a bit of a pain, because of the paint. It will aslo be kind of messy, but it will come off, and expose the wall underneath!!
