Covering the wet poultice with a sheet of plastic wrap slows the drying process of the active chemical. Hueston fastens the edges to the countertop with blue painter's tape. (Regular masking tape is too sticky and may remove sealer or even dull the stone surface when it's pulled up.) Then he pokes several small holes in the plastic wrap so that some air can circulate around the poultice, allowing it to dry and to draw the stain out as it does. When the poultice is dry, Hueston removes the tape, and the plastic with it.
