How to Paint new plaster
This is often an area of confusion and malpractice, so here is the definitive guide to the do’s and don’ts of painting new plaster.
- Allow the plaster to fully dry to a nice pink colour before even considering paint, this of course can take anything from 48 hours to a week depending on weather conditions and heating.
- New plaster is highly absorbent and so needs to be sealed before hand, sealing the plaster will not only save you money in terms of paint but also your arms in terms of effort.
- Professional decorators generally seal new plaster by applying a light slightly watered down white matt emulation, DON’T use one coat or any expensive paints for this first ‘mist coat’ , in fact the cheaper the paint the better as its thin. If you however are using a thicker quality paint for sealing then you will need to water it down a tad, our decorator suggests 1 part water to 5 parts paint.
- Don’t use pva glue to seal your nice new plaster as it will seal in moisture as well.
- Once this seal is dry any imperfections in the plastering will now show, these can now be filled and sanded if needed.
- Now you can apply TWO coats of quality emulsion in any colour you like, again for best results avoid one coat paint.
-Generally when it comes to painting less is more, several nice thin coats are far better than fewer thick coats.
