How do I correctly prepare the surface?
See Technical Data Sheet or container for surface prep information.
What is the approximate surface area coverage for the product I am considering?
See Technical Data Sheet or container for coverage areas.
What is the minimum application temperature for epoxy?
Different products have different minimum tolerable application temperatures. Please see the individual product pages on the website or the Technical Data Sheets for the product.
Can I use the hardener from one of your epoxy systems with the resin from another?
No. Epoxy resin systems are two-part products where each part is designed to go with the other in the specified proportions.
How much clamping pressure do I use for an epoxy glue joint?
Epoxy adhesives, being gap-filling glues, need only enough clamping to close the joint. Unlike other glues, epoxy requires low pressure and a proper film thickness of resin to make a proper glue joint.
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.
