I have a house that was built in the 1950's and have plaster walls. I am taking down the wall paper in my kitchen and I don't know what do you next. I would like to paint it but do I need to prime it first?

You'll want to repair or patch any cracks or holes with stuff called joint compound first then paint over it with a geneous coating of Kilz primer. Kilz is about the best primer out there and is very tough and long lasting. Let it dry for at least 24 hours before you paint over it. Good luck!
We live in an old farmhouse with plaster walls. We are struggling with paint staying on the walls, especially the hallway walls and hallway ceiling. The paint is always cracking and chipping off. The last time we painted, it was only about 1 month before the cracking and chipping started. Any suggestions on what to try to get the paint to better stay on the plaster?

Well I'm your local paint department. To me, it sounds as if you are painting with a water based paint, or Latex, and going over an oil based paint. Water based can not go over oil based. It starts to peel and crackle within a few days. If you know you have not painted with water base over oil base, then the reason would be the surface you are painting over is not fully cured.
Peeling and cracking paint means moisture is still present under. Painting in rainy weather, high humidity, low temperatures outside can also cause peeling and cracking. You need to fully let what you have done dry. Dry for a week if need be then sand the surface smooth.
After use a oil based interior primer. I recommend Kilz Oil Base. Reason for that is because you can paint over a oil based primer using a water based paint, just not water based paint over oil based paint. The oil based primer will stick to any previous oil base paint it might come in contact with with no problems. Then your water based final paint finish will stick to the oil based primer.
But please, if it is at all humid outside, let the primer cure a few days longer then recommended on the can. It needs to be fully dry.
I own an old 4000 sq ft house, that is mostly plaster covered by wallpaper. The wallpaper is starting to come off in places and I want to take it all down and paint the walls. I (thankfully) started in 1 of the smaller hallways to find lots of cracks in the plaster. I bought some mud and tape and after quite a bit of practice, I fixed the walls in that small area.
I have a lot more wallpaper to strip. Does anyone have any advice on faster ways to prep the plaster or bypass it all together with painting techniques. I do not have much experience in this type of work, but want to learn. Plus it would be way to expensive to hire someone to do the work..

i've been working on early 1900's homes with plaster walls for25 yrs. I'd like to say one thing first. nothing replaces manual labor. Painting over wallpaper is just the biggest mistake any homeowner can do. It's typical and is done with success. But be warned..in the future if you decide to paint again and then again you will eventually degrade the glue underneath the paper and bubbles will form or the paper will start falling off the walls.
The proper way to fix and paint old plaster walls is to strip the old paper by any means you like. They all require hard labor. But hey, it's your house and you have a lifetime to finish it, so do it right. If the walls have not been primed or painted the go get yourself a good quality oil-based primer and seal the plaster.
Now you can go around and fix all the cracks and holes. Cracks should be gouged out and filled with plaster patch. If you like you could actually run some joint tape over the cracks and feather it back to the wall by applying 3 or 4 coats of joint compound.
After all the cracks and holes are filled to your satisfaction then you would sand and prime the patched areas with a Acrylic primer. Then lightly sand the whole wall with a 120 grade sandpaper and then caulk around baseboard, windows and doors.
Now you should re-prime the entire wall with an acrylic primer. Now you are ready for any type of finish paint you like. Jerry
What paint either gloss or matte do I use to paint a plastered wall? I know that you add water to it, but I can't remember what paint it is. Please can you help me by answering this question? Thanx.

I have a 1950's house with plaster walls and I prefer satin finish latex/acrylic paint. It reflects light without being shiny like semi-gloss. It is also easier to clean than flat paint. This type of paint also works well for the faux finishes I do for myself.
Prior to painting I removed a dated border. It peeled the paint underneath off revealing bare plaster which isn't covering with the paint. How can I cover this?
You will need to prime this. If the wallpaper lifted off chunks or chips of paint, you may need to fill that with plaster and sand smooth again. Then prime and paint.
I am living my mother's home, which was built in 1906. In 1993 my parents had the entire upstairs bathroom redone, removing wallpaper and using joint compound over the upper half of the walls. This was then covered with a latex semigloss paint. We had a ring support placed over the claw foot tub for a shower, which adds to the moisture in the room.
My question: For the past several years, nearly all of the joint compound has cracked and/or peeled off, revealing rough, but perfect plaster (no cracks) underneath. The joint compound will be very easy to remove, but now I wonder how this happened before restoring this. Was it the type of paint used or was it a bad match of joint compound over plaster? Should we skim coat with a thin layer of plaster to create a smooth finish before repainting? Should I use any special paint? My mother does not want to install a vent, so I realize that this will have to stand up to extra moisture. I should mention that the exact same problem with the joint compound is occurring in our downstairs back hall ceiling, which was also done in the 1990s.
I live in the UK but was born and raised in the US, and restored several early 20th century homes whilst living in the US.
From what I recall of how US homes were built in the early 20th century, your plaster under the joint compound is likely a plaster and lathe combination. If the painters who did the work in the late 20th century didn't understand how to properly prepare the plaster and lathe surface it's no wonder the bond has failed the way you are describing, especially with the high moisture in affected areas.
Also, the type of plaster used in US homes of the early 20th century wasn't consistent-each builder mixed his own because, lol, Home Depot or even Ace Hardware weren't around back then. Even the building materials one could order from Sears Roebuck Company were not necessarily consistent. So the joint compound made in 1993 may be reacting to something in the 1906 chemical compound of the plaster applied over the lathe wall framing.
There are several good 'this old house' type books and websites that can give you excellent advisement on the proper 'next steps' in solving your problem (starting with determining what makes up the original plaster and then proper surface prepping). Use a search term that includes the words early 20th century plaster wall surface preparation.
However, without the installation of a vent you will more than likely continue to have moisture related problems. Properly prepared surfaces can only go so far.
If you are asking about a UK home, my husband (a retired historic building conservation officer) says the Artex joint compound (used most in the UK until the early 2000s) has very likely reacted with whatever type plaster the wall was constructed with.
He said that asbestos is a very real concern considering the age of the building and that you should contact a joiner who is certified in sorting this safely and correctly.
He went on to say a vent needs to be installed; Xpelair ventilation products are reliable and reasonably priced.
