Definitions

  • Traditional plaster has a smooth monolithic appearance that is considered to be a model surface. It accepts a variety of decorative finishes, such as paint, wallpaper, and the new faux finishes. However, the plaster also reflects sound, thereby increasing noise pollution. Some sound frequencies are also distorted, making the reflected sounds even less desirable.
  • acoustical panels are well-suited for absorbing sounds.
  • the surface of the panel is treated to provide openings into which sounds penetrate.
  • the panel may be needled, that is, it is punctured with rows of needles that create pores in the panel surface.
  • the sounds enter the needle voids and pass into the panel pores.
  • the sounds reflect off the walls of the voids or pores, a portion of the sound is absorbed. This results in little or no sound exiting the panel.
  • the aesthetics of the panels are not widely accepted and consumers are looking for an acoustical panel without visible holes or fissures.
  • the present acoustical plaster system features a base layer mixture and a finish layer mixture.
  • the base layer mixture includes a first binder, a first thickener and a plurality of first particles, with the first particles being porous, lightweight, non-close packing particles having a first mean diameter.
  • the finish layer mixture includes a latex binder, a second thickener and a plurality of second particles, with the second particles being porous, lightweight particles having a second diameter.
  • the first mean diameter is larger than said second mean diameter.
  • the present system reduces the number and amount of supplies that must be transported to the job site. Only two packages, one of the base layer mixture and one of the finishing layer mixture, need be taken to the building area. At least the adhesive and panel can be omitted from the list of supplies that are needed.
  • the materials can be premixed with water at the production plant, further reducing jobsite mixing preparations allowing the applicator to use the product directly out of the packaging without the need to bring water onto the jobsite to mix the product.
  • FIG. 1 is a photograph of a base layer mixture applied to a cushion layer on a substrate
  • FIG. 2 is a photograph of the plaster system showing a finish layer mixture applied to a base layer mixture on a cushion layer;
  • FIG. 3 is a photograph of a cross section of the plaster system of FIG. 2 showing the relative thicknesses of the layers.
  • a plaster system includes a base layer mixture and a finish layer mixture. It is contemplated that the acoustical plaster system could be formulated with additional layers to optimize the acoustics for specific applications.
  • first binder Another component of the base layer mixture is a first binder.
  • Any typical adhesive binder is useful in the base layer mixture.
  • Starch and synthetic polymer binders such as polyvinyl alcohol and boric acid, homo and co polymers of polyvinyl acrylate, polyvinyl acetate and polyurethane emulsion latexes are examples of useful binders.
  • Liquid emulsions are used if a ready-mixed base layer mixture is desirable.
  • spray-dried powders of the corresponding emulsions can be used if a dry-mix formulation is desired.
  • the first binder is used in amounts of from about 1 to about 15% based on the total weight of the dry base layer mixture components or from about 2 to 20% based on the total weight of a ready-mixed wet formulation.
  • the finish layer mixture produces a finish layer that hardens to a smooth monolithic surface. It is applied to the base layer by any known means, including spraying and hand troweling.
  • the finish layer mixture generally includes a second binder, a second thickener package and the second particles.
  • a dry base layer mixture formulation is prepared using the components listed in Table III.
  • the dry components are mixed in a V-shell dry mixer for 5 about minutes to form a dry powder mixture.
  • the finish layer mixture was applied to a cured basecoat layer which previously had been applied onto a 10" x 7" inch gypsum wallboard panel coated with a cushion layer using a %" notched trowel.
  • the finish layer mixture was smooth and had moderately good application feel.
  • a dry finish layer mixture formulation is prepared using the components listed in Table Vl.
  • the dry components are mixed in a V-shell dry mixer for 5 about minutes to form a dry powder mixture.
  • Table Vl
  • a cushion layer about 1/4 to about 1/2 inch in thickness (6-12 mm) of USG DUROCKTM High Performance Tile Mastic was applied to a substrate. While the cushion layer was still pliable, the base layer mixture was applied to the surface of the cushion layer, as shown in FIG. 1.
  • a finish layer mixture was prepared from the components of Table VIII.
