  1. What is HPC Coating?
  2. HPC is a high-performance coating that is applied to acoustical melamine foam base. Our exclusive water based HPC formulation improves durability and protects the acoustical foam from dust and dirt, allowing the surface to be cleaned using a damp cloth. The HPC coating is especially appropriate for use high-traffic areas. HPC Premium extends the HPC coating further by offering a line of brilliant colors from which to choose.

    • HPC Coating for Wall and Ceiling Panels:
      • Coating is applied to the face of panels only.
    • HPC Coating for Hanging Baffles and Clouds:
      • The coating will be applied to all exposed edges and sides.
    • HPC Coating for Drop-In Ceiling Tiles:
      • All necessary edges will be coated to provide a finished appearance.
  3. Are custom HPC colors available?
