    Description

    GacoPatch is a flashing grade, standalone silicone roof patch designed to be installed in a single application without reinforcement on a variety of substrates. In most cases, GacoPatch may be installed in a one-step application, reducing labour time and eliminating the cost of additional products such as primers and topcoats.

    New and improved technology allows for GacoPatch to be a long-term repair solution. GacoPatch does not contain asphalts or acrylics, and is extremely durable. GacoPatch remains permanently flexible, even under ponding water, and is UV stable, so it will not chalk or crack.

    Recommended Uses

    • Use GacoPatch on surface cracks*, control joints*, coping joints*, gutter seams, membrane pinholes, rain collars and fish mouths*, or as pitch pan filler

    *May require the use of sacrificial tape
