![]() Cost ConsiderationsĬonvenience and quality increase the cost of a veneer plaster installation. There’s no three-day disruption for the occupants of the home and because there’s no sanding, there is no irritating and messy dust.Ī typical drywall job takes three or four days: One day to hang the boards and apply a first coat of joint compound, which then has to dry a second day to sand the first coat and apply a second coat (which also has to dry) then a third day to sand again, and, for a quality job, an extra day for a third coat of joint compound. In remodeling, this convenience becomes apparent. Plastering immediately follows the joint treatment, and a second (if needed) plaster coat is applied over the first after a brief period. Veneer plaster application is typically a one-day operation. It’s also possible to colorize the plaster coat itself, either by adding a high-quality paint to the plaster at the mixing stage, or by using proprietary coloring systems.Some people are happy with the plaster’s own natural off-white color, and consider the plaster’s smooth surface sufficient. 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.
