Review: Excellent Seam Tape for Vapor Barrier Joins – Flawless Seals Every Time! - 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.
Review: Great Tape. Does Its Job Well. - I used this tape to connect/seal the moisture barrier that I laid under my basement floor. The tape was easy to apply and was very sticky and secure. I like that it was very wide, so it was a bit forgiving on being straight. The tape is very durable and is also moisture proof, which is a requirement for a vapor/moisture barrier installation. The tape is easy to cut with a razor blade or pair of scissors.
