Hidden Gutter Process

Case Study

1. The patches are measured and cut to appropriate size. A release film is removed from the backside and they are primed with the appropriate contact adhesive.

2. The receiving membrane is cleaned and prepared for application of the adhesive.

3. The cleaned membrane receives the adhesive application. Proper curing time is critical in this process.

4. The patches are laid in, rolled with a steel roller and completed with a bead of compatible caulk.

The membrane used for the hidden gutter patches is not the typical material used for the rest of the built in gutter system. It’s a special rubber that is manufactured for the purpose of patching. Critical details such as substrate preparation, membrane selection, adhesive selection and caulking selection are where inexperienced contractors may fail.
