Sticks great

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.

This tape works great, has great adhesion and thickness for the money. It is a large roll, more than seems in the picture. The color is white as it should be.
