Painter's tape features edges that are treated with PaintBlock technology that forms a micro-barrier to seal the edges of the tape for super-sharp paint lines. It also prevents paint-bleed for clean, consistent results. Remove the tape cleanly from most surfaces for 14 days. High-quality adhesive is recommended for cured painted walls and trim, glass and metal.Painter's tape features edges that are treated with PaintBlock technology that forms a micro-barrier to seal the edges of the tape for super-sharp paint lines.
