Great stick and easy to work with!! It is my go-to for all crawlspace work.
Arthur – December 18, 2025
This isn’t just any tape. The quality is immediately noticeable – it’s a premium polyethylene-backed tape with a strong, aggressive adhesive that bonds seamlessly to plastic sheeting. The 4-inch width effortlessly covers overlaps, for precise, mess-free application in tight spaces, creating waterproof joints that lock out moisture and air infiltration.
Aesthetically, the white hue matched my plastic sheeting perfectly, creating seamless, professional-looking bonds that elevate the whole setup from DIY to polished. While it is too soon to speak about its durability, you can tell it’s built to last a long time.
This tape paired perfectly with the butyl tape from the same seller – two indispensable essentials that brought my DIY crawl space encapsulation project to a seamless finish.
