I need to adhere two pieces of lumber. What’s the best way to do that?

  • Sand the surfaces that you’re putting together so that they’re both flat and free of gaps.
  • Clean the surfaces with a clean rag. Don’t use water or a cleaning product.
  • Spread a thin layer of glue over each surface evenly and completely, although not totally covering them. Too much glue will actually weaken the bond.
  • Line up the two pieces of wood with the glue surfaces contacting each other.
  • Clamp them immediately. You want the pressure to be firm, but not so much that it forces a lot of the glue out of the sides. Clamp down until a few drops of glue are squeezed out of the sides.
  • Let those beads of glue dry for 20-30 minutes and then use a putty knife to clean them away from the wood. (Don’t use a wet rag. It will only spread the glue along the sides.)
  • Let the glue cure for at least 24 hours before you remove the clamps.
