Do you need to be careful when painting new plaster?

You should never paint on any surface new or old any where inside or out that is wet. To paint new plaster dilute emulsion by approximately 30% clean cold water to 70% matt emulsion and apply 1 coat. Then 2 coats of normal emulsion matt or silk it does not matter.I find if you put a fine film of water over your emulsion ie 10 mm and give a really good stir it goes on a lot smoother and you don't get the thick orange peel affect like you do with straight emo out of tub.And it is always best to use a good brand of paint Dulux / Crown. Hope you find this helpful. Regards Tom Ok but I think you are going a bit deep now so if you are not sure the plaster is dry when it is turns uniform pink or grey depending on which colour you put on wait another week to be on the safe side. but in my experience (40 years decorating) when colour is uniform plaster is dry.

Hi Agree with T.M. Decor, also using a trade paint might give you a better finish.

Never paint over wet plaster even if there are just wet spots is better to let it dry completely so you don’t get into trouble when painting the second and third coat of paint.

Hi, Never paint anything that is still wet, you need to let the walls or any surface prior to painting completely dry and be free of any condensation or mostiour that may lie underneath the surface, plaster - board takes on adverage 2 - 3 days to dry once plastered where as backing plaster can take up to 4 - 6 days its advisable to wait at least a week before considering painting it. On some acassions new plaster can take up to a month to completely dry in certen enviorments. Once it is dry completely, depending on the quality of the finish of the plastered walls you may need to very lightly sand the surface with 120 grit sand paper to remove and nibs and grit that may be on the walls then dust off. The next process would to be to apply 2 coats of mist coats this is watered down emulsion of a 60 - 40 % ratio which will sink into to new plaster and this acts a primer for the plaster so the base coat and tops coats have something to grip to because if you paint directly onto new plaster after a period of time it will begin to peel off revealing fresh patches underneath Agian you need to let it dry completely before moving on the next stage. Once you have applied your two coats of mist coats and it has dried you are then going to move on to applying a base coat of straight emulsion making sure when doing so you have cut in all the edges top and bottoms and corners of the room leaving no misses and have rolled an even coat, Again once dried you will need to go over it agian with some 120 grit sand paper to remove and imperfections you may of accumulated alonged the way. Then dust off throughly before moving on to your top coats. Top coats are most important to get right and again need to be cut in well and rolled evenly, when rolling a cieling it advisable to roll in the same direction as the light meets the cieling, I would recommend a vynl matt emulsion to give the walls a slight sheen to them and a more brighter finish. IF ROLLED CORRECTLY you should not need to sand between these coats and you should use a proffessional sleeve of a medium or short pille for a smooth finish preferably Hamilton or Purdy. Hope this info helps and good luck :) J.C.A DECORATING

Once the plaster is dry, apply a mist coat (50% water: 50% emulsion). A mist coat is made of watered down paint and applied in a thin layer. You should put a mist coat of paint on new plaster on your walls to seal it and prevent peeling.

never painting if the plaster is still wet

Hey there! You're right on the money with your painting plan. Just remember, before you start painting new plaster, it needs to be totally dry - this can take up to 2 weeks. Start with a breathable matt paint as a mist coat, it lets the plaster keep drying even after painting. For the top coat, you can use vinyl or silk-based paints, but make sure the plaster is fully dry, or else you might have issues with peeling or flaking. For humid areas like bathrooms, go for something like mouldtec. For less humid spots like hallways, a standard matt emulsion should do the trick. Just remember, you get what you pay for with paint, so cheaper options might not give you the best finish or durability. Good luck with your painting project!
