- Dimetcoat Series

The following topcoats are recommended for use with PPG SigmaCover 2:

- Amercoat Epoxies
- Surface should be dry and free from any contamination
- A detergent wash with Prep 88, Sigmarite 88 or equivalent is required prior to application of topcoats after 30 days of exposure
- If maximum recoat time has been exceeded, roughen surfaces
- Alkyd coatings and waterborne acrylic coatings should be applied after the film is dry to handle and not greater than three times dry to handle time
- Maximum recoating time is highly dependent upon actual surface temperature - not simply air temperatures. Sun-exposed or
otherwise heated surface will shorten the maximum recoat window
