Just wondering if any body has made anything using epoxy, I have a slab that is approximately 3’ long and 2’ wide
wth “live” edges on both sides and a couple of smaller pieces with edges just on one side. The larger piece I am going to cut some groves in and place some stones in and cover the hole thing in epoxy. The ather pieces I want to put the live edges facing one another and make a river going down the middle. My question is how do I make a frame around the two pieces to keep the epoxy from running all over, what do I use under them also. I plan on having the river boards be the bottom shelf so I want the river to be clear. Thanks in advance

Lots of things, but I don’t make thick, large pours because of the heat it produces curing. Other resins don’t have that problem though and some cure very quickly.

I’ve poured gallons of it for covering posters and prints, as well as using it for a super finish on several projects, since a coat of it is akin to fifty coats of poly.

Over the past year, I’ve been using it to fill large cracks and things in things I turn, to make jewelry for the wife using live edge and so on.

I’ve used resin epoxy from UScomposites for several live edge jobs. It works, and is a lot cheaper than some of the other brands, but I don’t have anything to compare to. It does get warm when curing. Exopoxy supposedly doesn’t do this and it is less prone to bubbles but again- I have not used their product yet. Tips- 1st coat is a seal coat. Just brush the wood pieces to seal off the pores. 2nd coat is a flood coat. Pour about an inch thick at most. Sweep over the area with a propane torch at moderate speed to pop the bubbles. Let it cure, then pour another coat to build up your thickness. Important- have a few containers on hand. Make accurate measurements when mixing. Too much or too little hardener WILL affect the cure rate and final cure of the product. Mix thoroughly, then pour the mixed product into a secondary container. Pour from secondary container to workpiece. The reason for this is that inevitably some of the product against the bottom corners and walls of the first mixing container won’t be adequately mixed. By pouring into a second container and then to the workpiece, u ensure that all the epoxy resin is equally mixed. Maybe a lil anal but I haven’t had a problem doing it this way

Mayday, if you leave a beer type cup full of epoxy and let it set, it’ll start smoking and melt the cup (early on lesson (back around 78)). However, just sloping it all over live edge won’t pose much, if any, problem.

As to bubble issues, even thin pours can be problematic with epoxy, thus the torch and the tricks mentioned below.

I used to buy my epoxy in five gallon buckets of A and B. I learned sealing the wood helped some situations because air in the wood would come up through the epoxy. Often, I just used the same glue (Elmers) I’d attach photos and such with as the sealer. The glue would not cause bleed through, like poly or the resin would.

Keep your resin warmed to make it easier to let it release bubbles. A 40 watt bulb (use the usual fire precautions) in a box may be enough to get things up to steam, so to speak.

For mixing small batches, say around a pint, I use tongue depressors. You can square the edges to get the corners better. I also use the depressors to lay the epoxy onto projects by breaking it about an inch back from the working end. It breaks, but does not separate. This allows the stick to be used as a ladle/spoon to scoop up the resin from the table.

I always covered my pouring table with visquine (clear window plastic) because the epoxy didn’t stick to it well and I could scoop the run off back off it.

I ALWAYS vacuumed myself, including my hair, before entering my pouring room. One fleck of anything will show on a large, flat surface and you’ll have to be quick to pick it out (keep toothpicks around).

And….mayday’s tips can make the difference between success and failure.
