sjm1580 Posted February 12, 2017 Report Share Posted February 12, 2017 Working on a pecky walnut table top with a moderate amount of filling required. Went with West System 105 coupled with 207 hardener. Began filling the pecky voids with temperature in the shop in the mid 60's and some of the voids have cured fairly well, while a couple have the consistency of hardened snot after 36 hours of curing. Some of the inconsistent areas were filled with the same batch mixture (using the West System Pump setup). I have tried using a hair dry on low heat to induce the curing process in the areas not curing. Just scratching my head on what it could be, same batch, inconsistent curing in similar but different locations, same temperature for all areas. I can rule out mixing problems because I was very diligent about proper mixing. Maybe the epoxy is interacting with the feces left by the bugs in certain pecky areas? Just kidding but any help or suggestions would be appreciated. Steve Quote Link to comment Share on other sites More sharing options...
Just Bob Posted February 12, 2017 Report Share Posted February 12, 2017 All I can say is that I have had the same thing happen with 207 and that it cured, enventually. Quote Link to comment Share on other sites More sharing options...

Just Bob, do you remember how long it took to cure? Thank you! Quote Link to comment Share on other sites More sharing options...

When this happened to me I was working on a project with large cracks, my shop temp was in the 60's during the day and mid 40's at night. It took several days to cure. I tried to use a heat gun to speed up the process that helped some but I was almost at the point of giving up when it cured. Even though I tried to be diligent with my mixing process I am sure I screwed something up. West systems has great customer assistance either goon line or give them a call. 1 Quote Link to comment Share on other sites More sharing options...

If it doesn't cure by tomorrow I will give them a call. Between now and tomorrow I will keep up with the power of positive thinking, chanting and meditation!

wdwerker Posted February 12, 2017 Report Share Posted February 12, 2017 Can you keep the shop warmer tonight ? Or tent an electric blanket over it ? Not laying directly on the top. Quote Link to comment Share on other sites More sharing options...

I don't for tonight but come tomorrow if things don't change I will try some fashion of keeping the temperature higher. Quote Link to comment Share on other sites More sharing options...
sjm1580 Posted February 13, 2017 Author Report Share Posted February 13, 2017 No change in curing. Talked to the West System tech service and the word is, if it hasn't cured yet it probably isn't going to. Next step would be to try and remove all the non cured epoxy and start over. Not quite sure how this would work out. Quote Link to comment Share on other sites More sharing options...
drzaius Posted February 13, 2017 Report Share Posted February 13, 2017 When mixing epoxy, it isn't enough to just stir it lots, you've got to scrape thoroughly along the sides & bottom to make sure there's no unmixed resin or hardener there. 2 Quote Link to comment Share on other sites More sharing options...
wdwerker Posted February 13, 2017 Report Share Posted February 13, 2017 I just use the Devcon 4.5 ounce bottles but I mix by stirring and scraping the sides & bottom meticulously. I've been pleasantly surprised that partial bottles were still good after a couple years on the shelf in the shop. 2 Quote Link to comment Share on other sites More sharing options...
