Removing Wallpaper From Plaster Walls
Wallpaper removal can be as laborious process and the best thing to do is to do it properly which will speed it up. Certain papers come off different ways. There are some wallpapers that come off very easily and there are some that are very stubborn and just won’t come off without a fight.
The easiest wallpapers to remove are sometimes the most expensive ones. These are the older pattern wallpapers that are basically a paper with glue on the back. When these wallpapers get wet they are porous and will get wet always through straight to the drywall.
The way to remove this wallpaper is to soak it twice. The first coat or application of water will start the process. When the paper is not soaking wet anymore just damp looking it is time to put a second layer of water on it. Quick note >put a little bit of soap/dishwashing detergent into the hot water <
also make sure that you have some type of cloth or bed sheet or tablecloth on the floor to catch all the dripping water. Do not push hard on the roller squeezing at the water let the roller apply the water gently moving upward on the wall applying the water evenly on the upstroke then lift the roller off-the-wall go to the bottom again and was an upward stroke apply more water.
When you are able to remove the paper easily with your fingernail it’s time. If you run across a spot that the wallpaper is not easily separating from the wall you should give it some additional water soaking. The whole idea here is to let the water do the work.
Sometimes you run into wallpapers that are plastic coated and this is a real hassle. This type of wallpaper you have to gently trying to move the top layer in one piece if you can. We have tried to use the Rotary perforator that you can buy paint store but that is still just as much work using this as it is to manually try to remove the top layer of plastic coating. This is a job of patients. Another method is that we occasionally use is a sharp window scraper that you clean the paint after Windows with scraping the plastic layer off carefully not to dig into the drywall. Once you have all the bits and pieces of vinyl part of the wallpaper removed you can continue with soaking the wall as in the previous section to finish the job.
Most probably under average situations and conditions there will be some plaster repair to do on the wall because of scraper gouges and cuts on the wall from when the paper was double cut by the wallpaper hanger.
Once your walls are totally dry and dry enough to sand, they need to be sanded smooth. Visually check any spots now for the plaster repairs. When applying the plaster make sure that you do not leave large buildups of plaster on the seemingly flat wall. Apply the plaster sparingly just to repair the damage because the more plaster you put on the wall the more you’ll have to sand off to make it smooth.
Now that all your walls have been plastered dried and sanded it is time to prime all the spots that were plastered this prevents the plaster from bleeding through the paint job. Make sure that your priming is nice and smooth and even with no roller marks.
You are now ready to put one or two coats of finish coat paint on the wall.
