epoxy for knot filling - recommendations3/14
we work with a lot of walnut and are consistently filling knots. we're trying to come up with a better method.
for small knots, or work that needs to be filled and finished in the same day - we use a five minute epoxy. often, we add black liquid dye to color it dark. this seems to upset the drying time a bit, so it takes longer to dry. typically, this means 10-20 minutes of dry time followed by sanding. some times the immediate sanding pulls some or all of the epoxy out, so we have to repeat the process. this is a bottleneck in our sanding process.
for overnight stuff, we typically use west systems epoxy. no complaints or issues here other than the dry time. we can, essentially, only use it for stuff that will sit overnight. this is not ideal as we seem to find new holes to fill throughout the finish sanding process.
would super glue or something else be a better option for getting work done? ideally, the alternative would be workable for 1-2 minutes, could take tint, and could be sanded level shortly after that. we could tweek our processes to allow for 1-2 hours of dry time but my preference is to ask for the moon first.
i don't work with cya "super glue" now because it is messy and the squeeze tubes seem to be one use only. maybe i'm just using the wrong brand.
any thoughts would be greatly appreciated.
Either bore out the knot and glue in a round plug, or inlay a butterfly key. I fill epoxy with dried, used coffee grounds, or toner powder. Your short 1-2 minute time repair isn't practical.
I use super glue (Fast Cap) for small stuff when in a hurry. Don't know how to color it. I spray activate down into the knot and then pour the glue on. I'd prefer not to spray activate over the top because this tends to make bubbles.
polyester resin. Boatbuilders resin. The resin that's in Bondo.
Quick, cheap, and dirty
Epoxy putty sticks is what I use. They look like a cigar with one part being the colour on the outside and 2 part in the middle. Cut off as much as you need, knead it together until mixed and apply. Bout 10 minutes and your sanding. They come in about 12 colours and can be intermixed if needed.
where is the best source for these epoxy sticks?
