Bob Smith Finish-Cure 20 Minute Epoxy

Bob Smith’s Finish-Cure 20 minute epoxy is an excellent, low odor substitute for polyester resins. It can be used for applying fiberglass cloth to wood or by itself to give wood a surface ready for primer and paint. Finish Cure can be sanded the easiest of all our epoxies and is excellent for the sheeting of foam core wings. Allow 8 hours for full curing.

For best results, Finish-Cure should be heated to a temperature above 85 degrees F or applying light weight fiberglass, lay cloth on balsa first, then brush on Finish-Cure. When fully saturated, go over the surface with a heat gun, and then squeegee off excess epoxy with a playing card from an old deck. Heat and remove excess several times for a light weight finish. If room temperature is below 70 degrees F use a heat gun on the surface several times for the next 2 hours. When dry, lightly sand, then fill surface with a low weight spakeling compound, scrapping off excess with a playing card. Sand to a smooth finish ready for primer. For heavy weight fiberglass, apply the epoxy before and after laying down the cloth. Finish-Cure is best mixed in a disposable cup.

Bob Smith’s Finish-Cure 20 Minute Epoxy is has the least discoloration over time.

Directions

FINISH-CURE™ is and excellent substitute for polyester finishing resins. It can be used for applying fiberglass cloth to wood or used by itself to give wood a surface ready for primer and paint.

FINISH-CURE™ IS NOT A STRUCTURAL EPOXY. FINISH-CURE™ is primarily used for Coating and Finishing. It is also the best choice for applying cloth to the inside of epoxy fiberglass fuselages. It’s also commonly used for the sheeting of foam wings.

When an ounce or more is mixed in a cup the working time (pot life) is 20 minutes. When spread into thin layers the working time is approximately 40 minutes.

THE FINISH AREA MUST REMAIN ABOVE 75° FOR 8 HOURS FOR PROPER CURE. If ambient temperature is below 75°, heat FINISH-CURE™ Epoxy and Hardener bottles with tops removed in the microwave for 20 seconds (use less time for partial bottles). After applying, you can occasionally apply a heat gun during the curing time or cover project with a large cardboard box with a lamp placed inside to maintain a higher temperature.

For applying to lighter weight fiberglass, lay the cloth on the surface and brush FINISH-CURE™ through the cloth.  For heavier cloth, apply the epoxy on the surface first, then brush FINISH-CURE™ through the cloth. When using FINISH-CURE™ for the sheeting of foam wings, make sure to apply FINISH-CURE™ to the wood and not the foam. Acetone and isopropyl alcohol work as the best solvents for cleaning uncured epoxy from surfaces
