I am a complete newbie to the use of epoxy resins and now I fear that I have messed it up !! I mixed up the two parts as instructed on the bottles, and spread it liberally - probably too thickly actually. that was 2 days ago and now the surface remains slightly sticky, which worries me a lot ! I have a horrible feeling that it isn't going to cure properly, or will it eventually harden up enough for me get in there with some abrasive and prepare it for a final coat? If not, I guess I will have to scrape it all off and start again...that will the 4th time, having tried the primer/filler, topcoat, clear coat route 3 times and realised that the wood quality is so bad it was never going to cover well. Incidentally, Fender use epoxy resin as a grain filler so I was hoping to emulate the factory process. What say you? Cheers Dave Dave the Luthier Tags coating resin curing problems.guitar

EC coating resin often does that, if left to cure in a humid environment-- it will leave the surface slightly clouded and sticky /greasy to the touch. It can be wet-sanded off ... If it has really not cured totally yet, (Test by trying to press a nail into the surface, if it does not make a deep dent, then you are Ok to start sanding :w00t If your nail leaves a deep dent, then you need to let the Coat harden completely .. just have patience and leave it for a week at over 20 degrees C. Then come back and test again. "Sapere Aude"... Dare to KNOW! The written word is the only truly efficient vehicle for transmitting a complex concept from mind to mind... 103% of all people do not understand statistics... Do not adjust our mind, theres a fault in reality :-)

Epoxies are very sensitive to the right quantities and if the ratio is significantly off, it will likely not cure properly which would lead to a tacky surface with it getting softer the bigger the error. Excessive humidity is also a factor but bringing the part into a warm and dry environment can often solve the problem. Warren Penalver Easy Composites / Carbon Mods - Technical Support Assistant

Have now managed to rub it down quite a bit, back to hard and dry surface and applied a second coat. I think one more coat and it will be ready for paint D Dave the Luthier
