Question from Sandrine:

Answer: prepare the surface to be painted, apply an undercoat, sand and apply the paint

Hello Sandrine, first of all, know that if the plaster is new, I advise you to wait a few months before painting it so that it is perfectly dry. If it is dry, it will be important for you to prepare the surface to be painted, to dust it and if necessary to fill in and smooth the holes and cracks. If your wall is very porous, you can apply a background fixer on the surface. Then apply an undercoat of paint on your surface to nourish the support. Let dry and sand with fine-grained sandpaper. Dust the wall with a soft brush. Finally, you can apply the 2 coats of acrylic paint that you have chosen. You too, send us your decoration question
