Customer Questions & Answers

Can I add hardener after the resin has been applied?

It has been over 24 hours since I applied a coat of resin to the live edge of a wood slab. The resin did not harden and is still tacky. Can hardener be applied to this coat of resin to make it harden? If not, can you suggest anything that will remedy the situation?
Asked by: Woodworker
You can, and your application, that is exactly what I'd try. But I have found that it doesn't work as well as mixing it up first.

How much resin will this 0.74 oz tube treat? Will be buying resin by the gallon (118 oz.) and want the most economical size of hardener available. Am familiar with body filler/hardener and the small amount needed, but believe there may be a difference with fiberglass resin. This tube does not seem like it would go very far. Are there larger sizes.
Asked by: al
The directions are on the back, drop by the store and read the back of the package. That will determine the large Qty. of resin you need.

Could this be used to make crafts like to suspend something so that it appears to float?

Asked by: Bookworm
Yes and no. When dry, the resin/hardener is a bit transparent, but a dull brown.

can this ResinLiquid Hardener repair a crack in a house window? Would it appear clear when done?

Asked by: Deb
Yes, you could use a mix of resin/hardener like glue, but it does NOT dry clear like glass, and it's brown when dry.

Bondo Home Solutions 0.74 fl. oz. Fiberglass Resin Liquid Hardener is rated 4.4 out of 5 by 13.

The whole BONDO Fiberglass deal from Home Depot ain't perfect, but it solves a lot of problems in the workshop. After years of watching people do fiberglass manufacturing on "How It's Made," I decided to try it myself. I initially bought a BONDO kit which had resin, hardener, cloth and a mixing cup. It was easy and fun, and, like I said, fiberglass solves problems. And yeah, you never get ENOUGH hardener in the kit, so hence this purchase, I'm happy with the BONDO products and have bought them over and over again.

Rated 4 out of 5 by from Good resin, very fast set The resin seems to work well, but it sets very quickly. You only get about 10 minutes working time, at most.

Rated 5 out of 5 by from Very satisfied with Bondo epoxy resin I used the Bondo resin to repair my lawn mower leaf pick up attachment.. Bondo worked well, strong, easy to use. You have to clean up with Lacquer thinner.
