Sanding – System Three Resins, Inc.

Sanding guidelines for applying multiple coats of product.
- Recoating or applying multiple coats of one of our 2:1 epoxy products (General Purpose, SilverTip, Clear Coat, MirrorCoat, etc.) can be done without sanding if done within 72 hours of the previous coat. Beyond 72 hours, sand the previous coat with no higher than 120 grit sand paper to ensure the next coat adheres or properly levels out.
- For S-1 Sealer and Cold Cure products, the recoat window is 24 hours.
- For all System Three adhesives (Quick Cure, T-88, Gel Magic, MetlWeld, etc.) sand in between coats for best adhesion if a second application is desired. Please follow all instructions on substrate surface preparation prior to applying System Three adhesives.
- For fairing compounds, putty, and pastes, please allow to fully cure then abrade or sand if additional product is to be applied.
