Painting veneer plaster is not required.Veneer plaster is much less likely to display any sort of visible shading difference. Even the most skillfully made drywall joints may show up in certain lights. On a drywall surface, paint can dry differently on the paper surface than on the joint compound base at drywall seams. Veneer plaster’s continuous surface is also a better base for paint.The top surface of plaster veneer is continuous over the whole wall, so joints almost never show at all-and certainly never leap out at the eye the way drywall joints commonly do.Veneer plaster is much harder than a regular drywall surface, making it less likely to get unsightly dents and scratches.When finishing blue board drywall, instead of applying several coats of joint compound to the seams between boards, a quick tape-and-plaster treatment to the joints is applied, and then the entire wall surface is covered with one or two thin (1/8 inch thick) coats of plaster.Ī skim coat of plaster can be applied to regular drywall or an existing traditional plaster surface, but first the wall must be painted with a specially formulated orange-colored primer.īlueboard drywall and veneer plaster offer two advantages over ordinary drywall-quality and convenience. The difference is in the paper covering: blueboard’s characteristic blue face comes from the special paper on the board’s surface, which is treated to bond well to a skim coat of specially formulated plaster. It also has the same core material: Gypsum, known to chemists as calcium sulfate. ![]() Blueboard has many similarities to regular drywall gypsum board: Like drywall, it comes in 4-foot-wide boards at lengths of 8, 12, or 16 feet it cuts with a knife and it fastens to wood or steel wall studs with screws or nails. ![]()
