I have an apartment where there is projected plaster I would like to paint but the wall is smooth. How can I smooth this wall because sanding leaves traces?
There is a specific coating to smooth a plaster. All you need isapply on the old plaster until total recovery. It dries in 24 or 48 hours depending on the thickness. Then you can sand it easily and you will get a smooth wall ready to receive the wall covering of your choice (paint, wallpaper, etc.) in order to permanently cover the old interior plaster.
