PIG Ceiling Tile Absorbent Pad is a leakproof barrier that prevents minor nuisance drips from discoloring and destroying ceiling tiles. Heavy-duty, 8-layer absorbent pad discreetly rests on top of your ceiling tile to catch and retain minor drips. Poly backing prevents absorbed liquids from staining the ceiling tile. Low-profile and lightweight pads won't interfere with above-ceiling structures or cause tiles to sag. Prevents panel staining from minor drips.
