Good morning! Im stumped… I got a 42” round sycamore slab and need suggestions on filling cracks and finishing with a natural look. So far ive flattened, added 3 dutchmen, and sanded to 400. I do and dont want to use epoxy for cracks. I do because it would be the first time using it and i dont bcs its end grain and would just drink it costing me $. What other alternatives do you recommend? For finishing, im thinking of just using dewaxed shellac and MAYBE minwax poly as a final. What would you do? Your opinions and suggestions are appreciated. Thanks! |

Rev – surely that much epoxy to fill the crack will not send you to the poor house. jus my humble Dos Centavos . . -- I am a painter: that's what I do, I like to paint things. -- |

You can probably fill that with a pint, maybe up to two. Epoxy won’t soak into the end grain very much so I wouldn’t worry about that. It’s pretty viscous. Where you can run into real waste is trying to seal the bottom so it doesn’t run out. The weight will make virtually any tape sag and you’ll wind up with a pond of epoxy underneath. I work extensively with mesquite, so I have gallons worth of experience with epoxy. For starters, you’re lucky that the area is contained and not a bunch of checks out the edge. That makes confining the epoxy easier. I’ve tried everything, starting with painter’s tape, which adheres to the glue and makes a mess, then clear packing tape, which peeled off beautifully but didn’t adhere to the wood all that well. I finally found that a product called stucco tape is the answer. 3M makes one and Shurtape makes one that’s available at Lowe’s. The key is that it should look like vinyl, not woven like duct tape. I’ve seen both labeled as stucco tape, but the woven one will not work well. Apply the tape in a wide area, not just a strip along the crack. You need that to keep it tight. I find using a stiff brush to work it down onto the wood helps it to follow all of the contours. Finally, make your first fill about 20% of the space. Let it get firm, then finish the pour. That helps keep it from running out. If there are crevasses coming off the main openings, you’ll see the second pour drop. Just let it go, wait for it to firm up, then top it off. It takes patience, but it’s the best way to go with a piece of wood like that. I also like to use black pigment that System Three offers. Others on here say they’ve used things like TransTint dye, so I’m sure that works too. Good luck. I’m sure it’ll come out great. -- Half of what we read or hear about finishing is right.

I often use Alumilite casting resin to fill large voids a cracks. It’s also a wood stabilizer. |

Depending on the intended use, I would consider filling with resin at least part way. Possibly inlay some colored material. -- It is a sin to covet your neighbor’s wife, but his woodpile is fair game. |
