Wallpaper Tips
What the steamer is actually doing is putting the hot steam through the wallpaper into the adhesive. When this hot steam mixes with the adhesive, it will begin to break up, or soften the glue, and allow the paper to be peeled from the wall. But, in this process, what happens is the glue is left behind on the walls. You really do not want to put the steamer directly on the wall, as you will start to peel the paint, or even bubble the paint up. This is where the vinegar comes into use.
To use the vinegar, mix the vinegar with water at a ration of 1 part vinegar to 4 parts of water. Get a bucket of warm water and a rag or sponge. Spray the vinegar and water mixture onto the walls, and wait a couple of minutes. This vinegar mixture will soak into the glue, and make it wet again, and easy for removal. Use the rag in the warm water to wipe off the glue. Continue like this until all of the glue is removed. You will need to change out the buckets of water periodically. Once you are done, and the walls are dry, double check the work. There are likely spots which will need to be washed again.
This 2 part method has proven to be the best method for removing wallpaper for me. This method will likely be the least expensive as well, as the only real cost is for the steamer. If you try one of the other methods, and you mess up your drywall, you will need to fix, or even replace this drywall. You do not want any part of this, as this will make much more work. Try the steamer and the vinegar mixture, and you will agree it is the best method getting started with house painting and wallpaper
