Using the CP 27® 14 - Day ShurRELEASE® Blue Painter's Tape is easy. First, clean the surface you want to mask to make sure there's no dust or dirt. Then, carefully apply the tape along the area you want to protect. Press it down firmly to ensure good adhesion and prevent paint seepage. When you're done painting, you can remove the tape within 14 days for the best results. Simply pull it off slowly at a 45 - degree angle to avoid any damage to the surface. For temporary indoor floor marking, it can stay on most surfaces for up to 60 days. However, don't use it on hardwood floors. After use, store the tape in a cool, dry place to maintain its quality.
