Filling cracks from bad glueup

If you want to fill them you will need to do so before putting on BLO. The oil will make glue-ups very difficult.

If these are really 1/32 inch gaps then either yellow glue and re-clamping could work. But I would be tempted to use epoxy and a heat gun. The epoxy will become very loose under a heatgun and will set very quickly. Thus it will get deep into the cracks. You may need multiple applications of epoxy to completely fill it, but you will know relatively quickly.

Glue and fine sawdust. Use it all the time.

I also use glue and saw dust. You can turn it into a paste for larger cracks with yellow glue. For tiny cracks i put crazy glue and sand right over it to mix saw dust and crazy glue.

5 minute poxy and sanding dust. Tougher and able to withstand wood movement through humidity cycles.

I’m a big fan of West System epoxy however it is rather expensive. I use the slow setting and it gives me about 10 minutes before it starts to harden. You can use mineral spirits to thin it out. Mix 4 parts epoxy to 1 part MS. A friend of mine makes it much thinner and fills the cracks. You might want to put tape on the bottom of the cracks and prevent the epoxy running all the way through. Since the cracks are so small I’d suggest not adding sawdust.

If you go the West System route I suggest getting the mini-pumps, one pump with each is the correct mixture. If you want smaller quantities get some syringes. When I need to replenish my supply I get one quart of 207 hardener and one gallon of 105 resin. This amount cost about $150 including shipping.

I also use the LOCTITE, see http://www.lowes.com/pd_192926-69-1365736_0__?productId=3218759&Ntt=epoxy+glue&pl=1&currentURL=%3FNtt%3Depoxy%2Bglue&facetInfo= but it does set rather fast. You can also thin it as well.

White/yellow glue will work and you can thin them a bit. When you sand don’t use a high speed otherwise the glue will heat up and gum up the sandpaper. White glue (Elmers) will dry clear whereas the yellow glue or titebond will not dry clear.

+1 titebond dries yellow and elmers clear. elmers and sawdust can even be stained.

I’m a + for the glue and sawdust.

The only way to fix this is to coat the entire benchtop with cement.
