![]() 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. 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 walls are much harder and a smooth finish ceiling than a regular drywall surface, making it less likely to get unsightly dents and scratches. This allows plaster to bond with the boards, while the internal gypsum core remains protected from moisture damage.Ī veneer plaster finish offer two advantages over ordinary drywall - quality and convenience. These specially designed gypsum boards are coated in two paper layers, one of which absorbs moisture and another that resists it. Later developments led to larger sheets of this gypsum board, which were essentially just drywall with a different exterior layer. Most commonly known as Drywall J-Bead, the Veneer Plaster J-Mold offers an even greater bevel for joint compound than typical drywall trims provide. Instead of wood lath, thin strips of gypsum board were used to anchor the plaster in place. The first plaster veneer techniques were very similar to the old lath and plaster method. Drywall began to replace lath and plaster in the 1950s, though plaster veneer was also introduced as a combination method. The first coat of plaster would be pressed through the gaps in the lath material, and then the second coat could provide a smooth, durable surface. About 13 millimeters (0.5 inches) of plaster was then applied to the lathing in two coats. Two-coat veneer plaster is applicable to a. This was a very labor intensive method that involved nailing horizontally orientated lathing strips to interior wall studs. These problems can be avoided simply by applying a continuous rock-hard layer of plaster over the entire surface. Prior to the 1950s, the lath and plaster method was the most common technique used to create interior wall surfaces in the western world. To ensure optimum performance from veneer plaster systems, it is critical that good application techniques be followed when applying the veneer plaster. Tints can be mixed into the plaster prior to its application if some type of color is desired, though it is also possible to apply paint or wallpaper at any point after the material has dried. ![]() ![]() The process of creating a veneer plaster finish begins with specially formulated gypsum boards, a thin coating of plaster can then be applied to the gypsum, resulting in a smooth, seamless finish. Plaster veneer is a method of finishing interior walls.
