Better Traction on Slick Glue

Better Traction on Slick Glue

Clamping is more challenging when the glue acts like a lubricant, which it does until it begins to set. Here’s a simple way to get more traction: I put a few grains of coarse salt or sand onto one of the mating surfaces of the joint after I’ve spread the glue. It takes very little grit to do the job. The salt or sand bites into the wood when you apply clamping pressure, preventing the parts from slipping. Sprinkle the grit toward the center of the joint for best success.

    do you think a little sawdust would work instead of salt or sand?

    Have you considered what the chemical effect of sodium chloride will have upon the holding properties of the glue? And that said ….. there are many different glues and some different salts, therefore creating many, many different possible chemical reactions. I don’t think I’d go there, especially if the glue is water soluble when wet. Any good material chemists out there?

    I’ve used the clay style cat-litter for years – the type I buy has tiny granules. I assume it’s pretty chemically-inert.

    For years I have used the finest grit sand blasting sand. You can buy it most anywhere. Silica is the best. It is an angular crushed stone and totally inert to wood and glues. Being angular it grabs the wood and very little is required.
