Accordingly, can I use cement board outside? It can be used on the exterior of buildings as a base for exterior plaster (stucco) systems and sometimes as the finish system itself. IMPERIAL veneer finish is applied as indicated above for a one-coat system. Allow the basecoat to set to provide proper suction for the finish coat. Leave the surface rough and open for the proper bond of finish coat. You want it to dry fast so the next coat adheres.Secondly, can you plaster over durock? Note that only two-coat veneer plaster may be used over DUROCK cement board.

Then use brown bag durabond with a handful of plaster of Paris and skim the area. It's a pinkish primer that gives you a base to Spackle to. Regarding this, can you skim coat over cement board? Re: Plaster Over Cement Board You can use plaster weld to prime the surface.

Apply stucco to cement boards with the help of a fiberglass mesh for adherence.Click to see full answer. Extensive preparation is necessary, but once completed, you'll have a beautiful surface, suitable for further finishing by painting or left as-is for a raw plaster look. In addition, choosing a one-coat or two-coat veneer system can affect the final cost, reflecting the greater skill needed to apply veneer plaster.One finish you can use on cement boards is stucco. Veneer plaster, including blueboard and plaster, can run anywhere from 20 to 30 percent more than a drywall installation. 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.
