Fire performance, beauty and durability for interior residential and commercial spaces Plaster Systems

P laster systems offer a number of practical and aesthetic advantages over gypsum panels and other interior finishes. Plaster permits a great deal of design flexibility, combined with fire performance, strength and durability. These factors improve lifecycle economy when compared to drywall. Because plaster systems are truly monolithic, they provide surfaces that minimize or eliminate irregularities associated with standard drywall construction (ridging, boarding, nail pops, etc.).

laster systems provide improved fire and abuse resistance over Plaster conventional drywall systems. In addition, they allow for a variety of aesthetic applications and better acoustic performance. Depending on the application, either conventional or veneer plaster systems can be used. Conventional plaster systems use a thicker plaster coat over a metal lath and provide increased fire and wear resistance, while one- or two-coat veneer systems are faster and less expensive to apply. Plaster systems typically consist of a substrate, a basecoat plaster and a finish plaster. Substrates Substrates...

Conventional Three-Coat Plaster Systems Conventional plaster systems are the best choice to attain a uniform, monolithic, blemish-free, smooth surface good to excellent wear resistance based on the type of finish plaster. These systems make intricate architectural with details and ornamental shapes possible. Conventional plaster systems offer excellent acoustical performance, proven fire resistance, increased abuse resistance, design flexibility for curves and compound surfaces, and lifecycle cost reduction due to lower maintenance costs. A three-coat conventional plaster system consists of a...

Veneer Plaster Two-Coat Systems While less expensive than conventional plaster systems, two-coat veneer plaster systems provide distinct advantages over single-coat veneer plaster and drywall systems, including a more monolithic surface with improved appearance under oblique lighting conditions. Two-coat veneer plaster systems allow truer wall surfaces and greater resistance to nail pops, joint ridging and joint shadowing/banding, with a wider choice of finishing materials and texture options. Two-coat veneer plaster systems use a finish plaster on top of a basecoat plaster. finish basecoat gypsum...
