PS250: size: 2" x 50'. seam taping is an easy process and an important step in properly preparing your surface before applying Ames coatings and paints. Why is it important? hot and cold temperature changes will cause a roof, wall, or deck to expand and contract. Over time, cracks and leaks can develop. The purpose of seam taping is to provide reinforcement over areas prone to splitting, such as seams or joints, and create a "bridge" that ties the surfaces together so water cannot seep through. Seam tape is used around roof vents, on flashings, over cracks and gaps, along the seams on metal or rv roofs, and in many other applications. Features Ames Peel Stick Seam Tape is a contouring, self-adhesive, heavy duty, fleece-backed butyl-rubber seam tape to use with any of our coatings. Changes in temperature cause the vulnerable areas in your structure to expand and contract, Ames Peel Stick Seam Tape reinforces these areas. Use this strong tape on wood, concrete, metal, and most types of roofing including RV?s. This flexible tape has 500% elongation to reinforce and create a barrier over roof vents, flashings, seams in metal, or any crack or gap. Peel off the backing, line it up with the seam or crack, and press firmly over entire surface. Must be top coated for exterior applications.
