    Why do I need mesh on seams?

    • The Rust-Oleum Universal Patching Fabric is a nylon coated fiberglass mesh that helps reinforce seams, and prevent splitting and cracking. Temperature changes will cause some shrinkage in the membranes, and applying a threecourse mesh will provide additional strength along leak-prone areas.
