Do I need to do anything to drywall before I paint it?

We recently bought an older home, in which the previous owner's hung wallpaper in the bathroom. We peeled it all off with ease (thanks to it being 50+ years old), %26amp; now are wondering if we can just go ahead %26amp; paint, or if we need to use a special primer first. I am thinking the drywall may soak up the paint, but I am no expert %26amp; could very well be wrong. I have only painted on top of paint, never on bare drywall before. Thanks!Do I need to do anything to drywall before I paint it?
yes use a primer tinted to match color you want to paintDo I need to do anything to drywall before I paint it?
I would want to find out if it's plaster or drywall. If the walls are truly plaster, the paper-like stuff you are feeling is the backing of the wallpaper, and has to be removed. If it's drywall, then a good primer won't hurt.





Have you tried banging a nail into the wall? If it's drywall, the nail will just go in. If it's plaster, the area around the nail will kind of, like, crumble. This hole can be patched, easily, and then continue with the priming.
You should take a lightly damp cloth and wash of all of the walls to remove any dirt/dust so the paint will stick better. It should be very lightly damp. It is always a good idea to apply a primer first as this will reduce the number of coats of paint that are required for good coverage. The last time I painted, I used a coat of white primer and two coats of tinted paint. Satin is good because it is washable and covers blemishes better than gloss or semi-gloss.
YES IT WILL. My step dad used to build houses and he did the whole drywall part. You need to prime it with white paint first. It might need two coats. Then go ahead and paint it with the color. I would also recommend using putty to fill in where the screws are and any holes. That will also help it look nice.
Yes best to prime it. Though you may not see anything left behind there may be some glue so I suggest also a light sanding before you prime. As well fill any holes if required. A good primer is zinser super adherent primer.
Paint the walls with a primer first, such as Kilz or Zap.


I would use a good quality interior laytex paint eggshell or semi gloss
Are you sure it's drywall at 50+ years old? Anyway, you must use a sealer coat to prevent any reaction between materials. Speak to your paint store about acrylic paint for bathrooms (steam).
just prime the wall,


but ask your local paint store to recommend one. I used new construction primer on new drywall...
nopeee
hi kristen





if your home is 50 plus years old you don't have drywall in it unless it has been completely renovated. if the wallpaper came off easy and the walls are not painted that also tells me you have plaster and not drywall. if drywall is not painted or just has a water based paint on it the wallpaper will be very difficult to remove. what ever it is you first must make sure that all of the paste is cleaned off before doing any painting try TSP and water and use a plastic scrubbing pad. rinse well and allow to dry. repair any damaged areas and prime with 1 -2 coats of drywall primer. if you can have it tinted to the colour of your finish coat. you can purchase paint specially formulated for kitchens and bathrooms but i think that it is a waste of your hard earned money. a latex semi gloss or eggshell will work just fine. do yourself a favour and don't buy the crap from the big box stores. pay some extra money and buy a top quality paint like benjamin moore or pratt and lambert and if you want the very best find a farrow and ball dealer.





it looks like you have a product on your walls that was known as beaver board. your walls most likely have an alkyd paint on them, that is why the wallpaper came off so easily. if it didn't you would really have had a major job stripping it. if it was me i would rub some methyl hydrate on it if the paint comes off it is a water based product. i would still reprime and finish coat. if it is an alkyd paint i would apply a coat of alkyd primer then your finish coat.
Paint companies make a primer that's specifically made for bare drywall. Use that. Also, when you put on the primer, don't expect it to cover completely. That is, you might see the shadow of the drywall patches and such through the primer. Don't worry about this. Unless you're using a thick stain-blocking primer like Kilz, the purpose of the primer is to help the paint adhere to the wall.





Also, don't use cheap paint. Cheaper paints don't cover as well and you'll just end up putting 2 or 3 coats on. So, in the long run, it's actually more expensive than better paints. I would recommend getting the paint at a specialty paint store (Sherwin Williams, Dunn Edwards, Frazee, etc) rather than just getting whatever's on sale at the Home Depot.





Before putting on the primer, inspect the wall for any bumps or ridges from the wall paper. These flaws will be very apparent on a painted surface, especially the semigloss that's recommended for bathrooms. Lightly sand down any imperfections with about 100 grit paper (or better yet a drywall sanding screen - these don't clog like sandpaper does). Then wipe down the entire surface with a damp terry cloth rag to remove any sanding dust.





Then prime and paint. Note that most primers are dry enough to apply a coat of paint over them after about an hour. Check the can for specifics.
