Removing wallpaper is a tedious task, Sometimes it is easy, sometimes not, depending on the wallpaper to be removed.
Here I will tell you a way of removing wallpaper that has been painted over from plaster walls.
Here are the tools you need for an effective job at wallpaper removal
1- Roll of plastic ( 1 ml ) thick
2- A couple rolls of 1 1/2″ masking tape
3- Wallpaper scraper
4- A few packs of wallpaper scraper blades
5- 2 gallon sprayer bottle (garden bug sprayer type)
6- A bag of TSP(trisodium phosphate)
7 -Some dry rags
8- 2 gallon bucket
10- Putty knife
11- N-95 dusk masks
12 A step ladder
13- Trash bags
So first things first !
1- Make sure the heat and air conditioning are turned off. If possible, turn off the electrical power to the room.
2- Its best to have the room emptied of furniture if possible, for that make it easier to maneuver around the room. (If not push all the furniture to the center of the room and cover with a plastic drop cloth).
3- Wipe off the baseboard with a dry rag to get the dust off. (This will help the masking tape stick better).
4- Go around the room, tape the baseboard with the masking tape, leaving the bottom edge of the tape not stuck to the baseboard.
5- Roll out the plastic the length of the room (adding on about 2 extra feet)
6- Unroll (open) the plastic. It is usually 9 feet wide.
7- Tuck the plastic under the edge of the masking tape that is not taped to the base board. Press the plastic to the tape so the plastic adheres to the tape.
8- Now we need some elbow grease. Start by scraping off the layer of paint off the wallpaper. Scrape as much wallpaper (dry scraping) as possible.You probably will have to change the scraper blades a few times. They dull pretty fast.
9- Fill up the 2 gallon spray bottle (garden sprayer) with hot water and about 4 tablespoons of TSP. (TSP acts as a water softener, so the moisture penetrates behind the last layers of wallpaper faster).
10- Pump up the sprayer and start spraying walls from the bottom up. Do the 1st spray around the room lightly, then spray the walls of the room a 2nd time. Wait about 15 minutes and spray the room a 3rd time. Depending on the wallpaper, type of paste used, etc., the walls may have to be sprayed multiple times.My experience is sometimes it is ready to be scraped off in 10 minutes, other times a few hours.
11- When the wallpaper is saturated enough, it should scrape off the wall with ease using the wallpaper scraper. If when you start scraping the wallpaper and it leaves bits of wallpaper, it means the wallpaper is not ready to come off the wall yet and need to be sprayed again and let soaked for a while more.
12- Scrape off a section of the wallpaper and wipe the wall down with warm water & a sponge >that gets off any remaining wallpaper paste.
13- Use a putty knife to clean up the edges around the ceiling lines, doors, windows baseboards, etc. (any place where there is trim)
14- Make sure all the walls are wiped clean.
15- Pull the tape off the baseboard , plastic included. (That is why always tape the plastic to the baseboard. the plastic collects the water, scrap paper and the paste, etc. and you end up with a clean floor)
16- Wrap up the plastic (with the trash),throw in the trash bag.
17- Now you have a room with the walls completely removed of wallpaper.
