I want to paint a room that has the walls plastered?

The answer from "lightningiver" is about your best bet, except for one thing. You will have to remove all the plaster spots from the wall, then sand a great deal to remove the rest, alot of sanding, everything will have to be uniform as you can get it by eye.when the sanding is completed, you're going to have to wipe all the walls to remove the dust.(You said you didn't have the dough for a pro, to do it near right you'll have to put some effort into it) Once you've wiped the excess dust from the walls, you will have to prime with some kind of cheap paint. (lightningiver didn't mention this) If you're going to spend good money for a good Latex, I wouldn't put it on the walls without a primer. K-mart sells a very cheap white paint that might suffice as a primer, but you can look around for one that is within your budget. GOOD LUCK!!!

Unfortunatly, if the textured mud is coming off of sheetrock, the only way to make it look good is to scrape it all off. If you paint over it, what is left will eventually peel, taking the paint with it. The cheep thing to do is to take off the big stuff with a puddy knife and get some fine grit sandpaper or sandblocks to take the rest off. Just sand until uniform and smooth. This will also prime the wall for a good latex paint. If you do it this way, it should take many years for the paint to flake off, which will save money redoing the job in the long run. If there is something else that you havent mentioned, and are unsure about, go to the yellow pages and call Home Depot or Low's home improvement stores and see if you can talk to someone about the problem. Sometimes these places manage to hire a few people that know what they are actually doing. good luck.

a a million gallon backyard sprayer and some DIF. you'll get it at any abode progression save. i take advantage of a 4" scraper (razor blade) mix the DIF with warm water, pump the sprayer, spray it on the wall, wait a couple of minutes spray it lower back and it regularly comes properly off with little attempt. If the wallpaper has a vinyl coating or paint on it you may want to get what's termed a paper tiger, it really is scratches the wallpaper and helps the dif to penetrate more advantageous. you could also use a application knife once you're careful. provide the DIF a at the same time as to artwork and make optimistic you're not any more getting the pre-mixed stuff. A gallon prices about $15. i have finished this many cases to my residences and it extremely works tremendous the in uncomplicated phrases genuine difficulty you run into is the possiblity of the plaster being free yet that's an finished new set of complications in itself.

yes scrape off any loose chips of plaster

it may seem like alot of work but it isnt

just take a scraper and make one pass over the entire walls / ceiling that you will be painting

one pass is sufficient so it shouldnt take long at all

then you should use a primer and if you dont actually have primer you can use any white water based paint as a primer which will put a base and make the final paint look nice

Scrape off all the loose and flaking plaster, then paint a latex primer over it. It dries pretty quickly, about an hour.

If you don't prime first, the plaster will soak up the paint.

Your better scraping off what you can and going over the walls with thin coat of joint compound to smooth out any rough spots. There will be some sanding involved and it can get quite dusty so I would suggest being careful not to apply too much joint compound. After you sand your ready for paint.

Truth be told ........you can get some sand paper and sand it smooth. That will help get the flakes off. You can buy some filler to smooth out any rough surfaces.when its dry you just paint right over it.

It wont cost that much at your local hardware store to get the sand paper and the filler.

I hope this helps.

If I were you, so you don't paint it all then it all start flaking therefore wasting all your paint and efforts. I would sand it down to make it smooth then paint. Good Luck

sherwin williams sells an excellent bonding agent, if you want to save yourself a lot of work use it first, it's about 30 bucks a gallon, but worth every penny.....oh yeah it's not a paint....it's a bonding agent, use that before the priming and after priming then paint....you'll love it

go to your local Lowe's or home depot, talk to one of those guys, they're great. I would put a primer on the walls, that would probably do it, but ask a pro 1st.
