Plaster should normally dry within four days ready to paint depending on heating / weather/circumstances Also the surface that’s been plastered like New plaster boards /painted surface’s Of previous plastered surfaces It’s best to leave a window open for ventilation Never forget to apply mist coat of paint before painting on new plaster.

I would wait minimum one week before painting new plaster .Normally the surface would be pinky white when ready for paintwork,similar if using grey plaster.Plasterboard surfaces normally take 3/4 days where as backing plaster normally take 5/7 days to dry .You should ensure there are no dark patches on the plaster finish before painting,uniform light colour is a key sign that your plaster has dried thoroughly.The time it takes plaster to dry will have numerous factors eg;time of year,central heating,thickness of plaster.You should make sure that the room is well ventilated,opening windows and doors where possible to let natural ventilation dry the plaster.

depends on heat of roof and ventilation but I would give it 2 week to be safe, sometimes it can be dry within a week and this is not uncommon, painting whilst wet can put it at risk of mixing in the plaster with the paint and changing the colour of the paint once dried, so I would wait until it's all the same colour.

this would depend on air flow and temperature. the plaster will reach a very light pastel pink colour when fully dried. painting plaster before fully dried can lead to paint flaking off.

I usually tell the customer to wait a minimum of a week before they can paint or if they are not in any rush to leave it has long as possible. Plus to leave a window open so it gets airflow so it drys better.

Plasterboard takes on average 2-3 days to dry when plastered, whereas backing plaster takes 4-6 days. No matter what material you have used, it is advisable to wait at least a week before painting new plaster and always follow the paint you using instructions to get the best result.

This depends on the time of year the ambient temperature the substrate which plaster is going on and whether it’s just a re-skim or float and sets. If it’s a re-skim or on plasterboard normally it would be dry within 2 to 3 days max. if it’s float and set which is an undercoat plaster skimmed with a finish plaster it could take up to a week. As it sets the plaster will go very dark and when it’s dry it will go very light with no dark patches. It can then be sealed with a watered-down PVA or emulsion paint prior to the application of two full coats of emulsion.

The answer to this can vary on many factors. If the plastering was carried out on new plasterboard then 3 / 4 days and the plaster should be dry enough to apply a watered down matt emulsion. If the top coat of plaster has been completed over the top of bonding or hard wall plaster then the drying time could be 5 / 6 days. Once the plaster has dried a light pink colour all over then your ready for decorating. It is not advised to try and dry out plaster quicker with use of heating as this can lead to plaster cracking and causing future problems.

Depending upon time of the year, central heating on or off, windows and doors open for airflow 3-4 days on average for a top coat skim. This time however is only when the plaster changes colour from a dark pink to light pink if gypsum based. It will still have some water in it at this stage and ideally should be given longer to dry fully. If you are going to paint it using vinyl paint it must be given at least two weeks because the vinyl seals in any moisture still present which can then cause the plaster to fail, i.e blow off the wall. If you are going to get a lot of plastering done it's a good idea to leave as many doors and windows fully open to allow the moisture out I have known door frames to warp due to the high humidity in the air because customers did not vent the rooms.

Plaster drying times can very on many factors. Main ones are temperature and the thickness the plaster has been applied and also how much moisture is in the air and also air movement plays a part in the time it takes. On average it takes up to three weeks with gypsum plaster.trying to speed drying will normally introduce crazing or poor adherence and lead to fail You can however use airless plaster which is normally dry within 48 hours

It depends on multiple factors which include the background that has been plastered onto, the temperature of the room(during the work and after), the size of room and amount of plaster used. If the work is onto of plasterboard or ontop of existing plaster I would say 2-4 days to dry completely in an averagely heated house. If the work includes a backing plaster (onto blocks or brick) and then a skim coat I would say 4-7 days to dry completely.
