Sanding and Re-Coating Guidelines for Applying Multiple Coats of Epoxy.

 

  • Re-coating or applying one product on top of another for most of our 2:1 epoxies (General Purpose, SilverTip, Clear Coat, MirrorCoat, RotFix, etc.) can be done without sanding if done within 72 hours of the previous coat. Beyond 72 hours, sand the previous coat or product with150 grit sandpaper to ensure the next layer adheres to the previous one. 

  • For S-1 Sealer and Cold Cure products, recoating can be done within 24 hours without sanding.  After 24 hours, sanding is necessary.  Sand S1 Sealer with 180-220 grit sandpaper.  Cold Cure Epoxy should be sanded with 150 grit.

  • For all System Three adhesives (Quick Cure, T-88, Gel Magic, MetlWeld, etc.) always sand with 150 grit prior to adding more adhesive or other epoxy products.

  • For QuikFair, allow to harden 4-6 hours then sand with 120-150 grit paper and apply more QuickFair.

  • For SculpWood Putty, more putty can be added without sanding if the first application is still tacky.  If SculpWood Putty has reached a hardened state, sand with 150 grit paper and apply RotFix Epoxy.  SculpWood Putty can be applied immediately to the wet RotFix Epoxy.

  • For SculpWood Paste, more paste can be added without sanding if the first application is still tacky.  If SculpWood Paste has reached a hardened state, sand with 150 grit paper and apply more SculpWood Paste.
