Since heavy nicotine tends to bleed through and yellow white pigmented water based paint materials, should the ceiling be primed first before applying ProCoustic?
No, the application of a primer will negate the restoration process. Primers will close the pores of the tile and leave the tile stuck to the t-bar system. Instead, ProCoat’s Acoustical Tile and Ceiling Cleaner should be used to chemically neutralize the nicotine. This will not have a physical effect on the tile and eliminates the bleed through problem prior to the application of ProCoustic.
