Topic tags/keywords: question tip finishing

A customer ordered a slab coffee table top and hand picked a specific slab for me to use. It finally came in the mail today and it has a LOT of cracks and punky spots. My question is what brand or type of pour on resin would you recommend to fix this? the outer portion of the slab is very porous and would require a decent quantity of resin to repair. I don’t care so much about the big crack but the small ones could be a problem with the table top long term since the outer edges move just from my pushing on it with my fingers.

I would use System 3. But, you might contact the folks at Jamestown Distributors. They have a lot of expertise as they offer epoxy products for the repair of boat hulls.

System Three S1 sealer. it is about as thin as diesel, will penetrate and harden. If you have soft punky wood, it will fix it and end any rot that is taking place. It will also seal out (and in) moisture so apply it after the piece is at a stable moisture content.

Never heard of S1 sealer, Paul. Just googled it and it looks like just the ticket.

it looks like system three only comes in 2 quart kits which is a tad pricey since I’m already going over budget by having to fox the rotted slab. if it’s the best option I will buy it if need be.

It lasts a very long time and you will find many uses for it. Just be sure to follow the instructions. It need a an hour gestation time before you apply it.

Man, I’m sorry you have to deal with a punky cookie like that! I’m afraid that thing will continue to split down to the pith.

it seems pretty dry I think I will buy the system 3 rot formula since i don’t have to ship it and I’ll buy some bar top finish to go on top. Worst case I can buy another slab of a similar size from the local architectural salvage yard.

I got the legs most of the way done today.

Hope the S1 works for you. Let us know how you like it.
That’s going to be a really nice piece.

How dry is it currently? I only ask because I had a log bench dried to 7.5% moisture content, then filled all the cracks. Couple months later a few cracks were continuing to open so I left it now for two years and the crack has doubled in width from when I originally filled it with epoxy. That doesn’t look too terribly thick so you shouldn’t have the same problems I did, provided it’s already very dry throughout.

it feels pretty dry the entire thing only weighs 12 lbs. the rotted portions feel like burnt toast just extremely brittle not bendy at all.

this is some of the nastiest material i’ve worked with in a long time. There is so much sap in the outer ring of wood that it clogs my sandpaper in seconds. I stabilized the cracks with some screws so they do not move while I am sanding it. The big crack was filled with rock hard putty and then regular stainable filler on top of that. It was a hellish experience trying to dam up the gap so i could pour the rock hard putty because tape would not stick.

The project has been a pain is what I’m saying. I will begin pouring the resin in the next day or so.
