Hi there. I really hope there's something I can do to save my project. I made a penny mosaic countertop and used the Tabletop Epoxy on it (pennies had already been glued down with craft glue 24+ hours earlier). It has been 60 hours and while some areas of the counter are nice and hard, there are sections where touching it leaves the impression of my fingerprints and it's gooey to the touch, but no so soft that it can be mushed around. Here are the details of what we did: The room we were working in is usually around 60 degrees so we put a space heater on high in there before starting. The bottles of epoxy were stored in that room. The space heater was not on in the room for more than an hour before we started mixing (so the ingredients were probably still very cold) Mixed the 1:1 batch gently by hand for 8-10 minutes with a thin paddle. It was thicker and more gooey than expected, but we used it to brush over the layer of pennies anyway and in hitting it with a MAPP-gas torch in places it seemed to cover adequately and make no bubbles 5 hours later we mixed another batch for the pour-over (same thing, 8-10 minutes slowly by hand). It was thick and gooey again, and it didn't do much by the way of self-leveling. However, we were able to spread it around with a thin laminated piece of cardstock and hit it with the torch in quick flashes. It wasn't as smooth as we had hoped when we were done, but it was evenly distributed so we anticipated it may need a sanding/topcoat upon drying to get a mirror-smooth finish in the end Now, here we are 60 hours later and the space heater has been running in the room the whole time. The table top is tacky in some spots. I grabbed all the thermometers I could find in the house and put them in the room. I discovered that the room itself is between 61 and 67 degrees and 41% humidity after 60 hours of space-heater supplement (so it was probably only in the upper 50's when we did the job). In retrospect and with the benefit of additional research, I speculate that everything must have been too cold. My main question is this: is the project ruined, or will it just take a longer time to cure? Thank you so much in advance for your help and advice. Chris from (chilly) Philly
