New Plaster

[Shaun-UK]

Hi there, I have just had a porch and small bedroom re skimmed and have a couple of questions please.

There is a small area in the porch that was plastered that has dried out too quickly which I guess is either due to being plastered over the sandy render stuff or me forgetting to turn the central heating off. I have been left with lots of cracks. It does look aweful but the plaster is stuck solid to the wall so can I just filler the cracks and paint over as normal?


What paint should I buy to use for the mist coat and a 2nd coat? I will be finishing off with Dulux Brilliant white Matt. The stores I have available are Wickes, Homebase or Jewsons.

How much should I water down the mist coat and the 2nd coat?

Thanks in advance

i would use easy fill, to fill the cracks and rub down after. get matt white paint for a base coat with about 30/40% water, give it two quick coats then paint over normal. make sure you leave the plaster for as long as possible to dry out.

OK thanks, plaster has been drying for a week already

As long as the plaster has not de-laminated, a little Easyfill should cover them but you won't know till you try it; leave a skim 10-14 days before painting. Cheap own brand matt is fine for misting but I thin 25-30% (40% is rather on the thin side!) & apply 2-3 coats in quick succession. Leave to dry thoroughly before applying your finish coats.

Sorry to be thick but what do you mean by this?

The cracks have come to the surface and are open but the plaster is stuck to the wall well enough. A couple of hollow sounds but hardly any to be honest. Was going to just fill and paint over and see what happens

Delaminated = blown = not stuck; if it sounds hollow when tapped or you can pick it off with your finger nails, it’s delaminated. Try the Easyfill, you’ve got nothing to loose.
