## Overview

My DIY Center Vapor Barrier Seam Tape is a 4-inch wide, 55-yard roll of commercial-grade polyethylene tape designed to create durable, waterproof, and UV-resistant seals on vapor barrier seams. Ideal for professional contractors and DIY enthusiasts, it ensures long-lasting protection against moisture and weather, making it essential for crawl space encapsulation, marine applications, and any project requiring reliable waterproof sealing.

## Description

When encapsulating, you will find that you have many overlapping seams from your vapor barriers. This tape effectively connects and welds the liner seams, creating a waterproof seal. Each roll of seam tape is 4 inches wide and 18 inches long.

Review: Sticks great
Review: 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.

## Features

- SEAL WHEN YOU NEED IT - My DIY Center Seam Tape binds and seals the seams to each moisture barrier for a water and weather proof seal.
- DURABLE AND RELIABLE - This multi-purpose and commercial grade polyethylene tape measures 4 inches wide and each roll has 55 yards of tape.
- HEAVY DUTY - Vapor barrier seam tape is also UV resistant, meaning it holds the seal in harsh weather and remains stable and sticky in the sun.
- APPLICATIONS Ideal when you need to make a waterproof seal in crawl space encapsulations or underlay seams, for marine use or when you need it to keep and maintain a seal on leaks.
- IDEAL FOR: Any contractor or DIY enthusiast will tell you that you always need a sturdy roll of tape. Get a roll along with great scissors for the perfect edge and length.

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.
