Workin my f/g flares.. Laying some fiberglass and the resin doesnt want set.
Instructions say it should set in 20 mins.. Its been 2 hours, and its still wet. Some of it is hard, and some other stuff is hard as well, but most of it is pretty bad. Any suggestions? Im going to let it sit over night and see what it does. Andrew |

Ditto on the comments about expired resin / hardener, they do have a shelf life.
Suggest if it is not hardening correctly that you will have ot strip it all off, you don't want incorrectly cured resin as a base, as it will propably cause problem later, like lifting or bubbling, Sorry, good luck PS be sure you have good ventalation, some of that stuff is none too good to inhale. Also adding extra hardener (thats what you meant I assume) to speed up the reaction may not be too good a plan. It can speed it up, but, more heat is generated faster, so warping/expansion can be an issue, and often the end product is too hard, hence more brittle and may more likely crack later. really best to stay within the manufacturers limits on mix, shelflife and temperature. |
