Can I paint directly on to plaster on a wall?

Question

If I have stripped paint off a wall back to the plaster, can I paint directly onto the plaster? When I stripped the paint, the plaster seemed to be covered in a light blue coating which came off with the old paint - do I need to put anything on the orange/brown plaster before painting?

Answer 1

You can paint on directly to the plaster but the plaster may absord some of the paint thereby making the whole process more expensive for you as you will certainly need 2 coats. Suggest you very quickly paint the plaster with a coat of watered down paint (emulsion) of the same colour before applying one very good coat of paint and you might give you a suitable finish. Hope that helps.

Use uni-bond mixed in with white paint. Always use a good quality paint you will get the best coverage that way. On freshly plastered walls use a mist coat which is very watered down paint and lightly roll over the plaster this will not have to be perfect as its just a sealant.(again a quality paint is a must) Hope this helps.

Answer 6

You can paint straight onto the wall. However make the first coat a thin coat of emulsion by adding water to it. About half and half would do the job. This seals the plaster and the next proper coat of paint will not soak in.
To save money use white paint as the sealer then paint with your chosen colour.
Use Dulux paint for your best result. It really is the best

Hi Im a decorator, please beforeyou listen to any of the above answers, you need to know this, im not saying there wrong but they arnt profesionals, what did you use to strip the paint, was it a chemical paint stripper, (nitro mors) or was it a water based 1, if it is the chemical 1, you 1st need to netralise the surface, in this case the plaster, the way you do this is by washing the wall with white spirit, really getting the wall wet, then leaving it to dry completely, then mix some paint up, with water either a 50 50 mix or somewhere close it doesnt need to me precise, then just paint the wall with what ever you want. if you have stripped the wall with a water based 1, do the same as above but with water. for the really profesional job, apply 1-2 coats of alkali resisting primer, then 2 coats of emulsion, good luck

Answer 8

Provided the plaster is in a good condition you should not have a problem. However, you might wish to seal the surface first. You should use a base of PVA mised 50/50 with water.
Then use an undercoat and probablt two top coats.
Don't bother using the one-coat varities. They are too expensive and not particularly effective.

When tyhe job is over and you are satisfied can you come over and do mine?

Answer 9

No you cannot you have to go over the wall with PVA sealant then you can paint on top if that, other wise the paint will get sucked into the plaster and be runined. You can buy PVA sealant at any DIY stores just ask someone for it and they should no what your on about. Hope this helps

Answer 10

You need to make sure that all loose plaster is off the wall, and the wall is dry.A decorators sealer,put on the wall, would help to stop the paint soaking in. You could first apply a small ammount of paint,to see how it looks.
