I want to do an end grain mesquite slab small table and fill the cracks with epoxy,glass,etc like I’ve seen others do. I’ve never used any kind of epoxy so am starting from scratch. Do you use 2 part stuff from HD or what? Buy it in qua rts,pints, or ? Any tips/pitfalls to avoid would be welcome. Thanks. ps I’d rather buy it locally rather than ordering if possible.

I just recently picked up a two part system made by Loctite sold at the orange box. Strong bond, but very yellow and seemed to bubble quite a bit, leaving air pockets. I have heard (or read) positive reviews for West systems epoxy, but I have never used it.

You want something that will be slow curing. Depends on how big before I could guess at how much. More likely at least into quarts for a table. They have some that is pretty liquid for self leveling but I don’t think it is that much of an improvement. You want thicker to fill gaps.

You will more than likely have to fill the gaps in layers and build up. (Along with making dams to hold it in.) Until you are used to it, mix the epoxy in SMALL batches. No more than 2 ounces total. The larger the batch, the faster it kicks off. Besides wasting it, it gets REALLY hot. Spreading it out in a thinner layer will let it not kick off so fast (I use styrofoam plates and bowls) As long as you are within a day (They say three days, but I don’t trust that much) each layer will still chemically bond with the previous layer without sanding. You can really start the next layer when it goes to the gel state.

I like System Three epoxy but the other brands are fine. Higher quality epoxy is less yellow than the cheap stuff. If you are going to have it outside, it will need to be varnished to protect the epoxy from UV light.

Once you get used to it, epoxy is really nice to work with and more forgiving than many types of glue. Just remember, you can always sand it off.

West Systems, for one, has a really neat dispensing system that’s nearly goof proof. It’s a slow setting formula. They sell thickeners if you need them. (colloidal silica)
No place anywhere near me sells it so I order from Jamestown Distributors.

this is a tray i made for my sister, i cut the flowers on the scroll saw and then insert them into the cut out i made with the router, i then took the epoxy with the red cedar saw dust mixed in and poured it over the wooden flower…after it hardened i sanded it and it came out beautiful…just a neat way to do this …it worked for me anyway…just a idea for ya…grizz

Grizz – You’re right, I Like it a lot. Does the addition of the sawdust alter the cure time/ workability appreciably?

no it didnt alter one thing…since they were a small area i did it with a 5 minute epoxy..but depending on how fast i think i can do a project..i would use something that cured slower if it was medium to large in size…i just did another one that im posting in the morning…i free hand cut with the router a fancy letter into the top of a box i made..its the letter R…and i mixes the saw dust from curly maple..it turned out pretty good…but next time i will use a softer white wood to mix in, as is gets into a finer dust then does a hardwood…but ill post it tomorrow and you can see it…good luck on your adventure…grizz

I have used a product called “Z-Poxy” I got at a local hobby shop and mixed powdered blue chalk (From the dollar store) with it, to fill in voids and cracks in Mesquite. Worked well for me. And the blue color looked nice in Mesquite.

Resin Research makes surfboard specific epoxy that is clear, will NOT yellow and is UV resistant. Most other epoxies will yellow in time.
