I was looking at places to order a sheet and my sweetie asked what I was doing. After I explained she brought me the one from the kitchen and said "use this it won't cost me a penny".
It's only been a couple of days and it's neither been hot nor cold, but so far the epoxy is holding fine. I cleaned the feet of the chairs with DNA before gluing. I used quite a lot of epoxy so it was almost squishing out because the inside of the feet were not flat, they had a weld spots. Rather than clamp I turned the chairs over and let the weight of the chairs hold them during the curing process. They set-up for 24 hours before moving to the deck.
