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

Drying Times


  • At ⅛" (3.2 mm) thick, in 24°C temperatures and 55% relative humidity, GacoPatch will be tack-free in 4 hours, fully cured in 40 hours, but can be rained on within 60 minutes
  • Product is moisture cure; low humidity will result in longer cure times



Surface Preparation


  • Remove loose material, dirt, and other debris from the application area with a stiff bristle brush
  • Cleaning of single ply membranes and other smooth surfaces with a solution of 9 parts clean water to 1 part GacoWash Concentrated Cleaner per its instructions is recommended for best results
  • Allow the area to dry thoroughly. [Note: Do not wash asphaltic roof substrates prior to application.]
  • Remove rust and scale from metal sur faces with a wire brush
  • Slick, prefinished metal surfaces should be abraded with a wire brush or sandpaper and wiped with a clean, dry rag
  • GacoPatch may be applied to damp horizontal surfaces to serve as a temporary waterstop, but any standing water should first be removed
