Acoustical Ceiling Restoration includes the application of a specially formulated acoustical coating to an aged/discolored ceiling system. Ceiling tiles, t-bars, and air diffusers can be restored to a new-like appearance at half the cost of replacement and in one third of the time. ProCoat manufacturers and distributes products/supplies used in this process. New tiles can be installed in a standard white color and then be re-coated in place to provide designer colors at less expense than the upcharge for special colors required by the tile manufactirer. Utilization of ceiling restoration in a renovation project can earn LEED credits as well.
