Topic tags/keywords: epoxy voids finishes west system systemthree

Hello!

Let me start by saying for some reason I have begun to overthink while making myself crazy and before I make this new purchase I need some guidance.

I’m up in the air about what epoxy to purchase for filling voids. I have used West Systems a while back and it did a nice job. I see many continuing to use it while now I see some using SystemThree. I like the West System process as it’s almost idiot proof with mixing. Looks like SystemThree fills voids as well but has a vast majority of many other types of products/applications/finishes which has their own place.
•West Systems vs. SystemThree?
•Pros vs. cons?
•Tinting?
•Etc.
•Any information or guidance would be greatly appreciated.

Thanks so much!
Ray

They are all pretty much the same… epoxy is pretty much just epoxy as long as it doesn’t have any fillers in it (like most of the syringe type things you find at the BORG). Some may have slightly less or more viscosity, but they all flow well when neat, and all can be tinted/colored.

Cheers,
Brad

PS: I use west system epoxy a lot for filling voids and cracks in wood… and the syringe stuff when I want to glue the sole back on my shoe :)

I use West System almost exclusively. Depending on the project I either use 205 or 207 hardener. 205 if the bond is not going to be seen, 207 if I need to tint or have a clear joint. It lasts forever and I really like the pump system. 2 years ago I needed to restore a chainsaw carving of “Bigfoot”. At 7’6” tall and 30” in diameter it is huge. The legs had rotted on the inside, and I needed a way to fill the legs and stop the rot. For that I used Abatron’s Liquid Wood and Wood Epox system. It worked very well, and was easy to use, except I had to use a measuring cup to mix and that was really messy. I tried to tint the Wood Epox, but it was inconsistent and I used the WS 207 for the visible part of the repairs.
I don’t think there is a huge difference between brands, for me it just boils down to what I am used to. Here is “Bigfoot” while waiting for repair:),

I have had success with both West System and System 3 T-88. The main difference is in viscosity, West system epoxy is a lot thinner and flows easier. T-88 is much thicker, I think it would be better at gap filling.

For small voids I use “Z-poxy” with colored powdered chalk for tint. It is actually a finishing resin and penetrates very well. It is thin and slow to cure.

West systems is very thin, but sometimes I add their filler product to make it thicker for the purpose of filling voids. With a little dye, it looks great.

Wood flour from a sander is excellent for coloring epoxy. The filled space will be a darker color, however, which could be a problem. I always thicken my epoxy because I think it makes a stronger bond.
