What’s the fastest way to apply glue to the mortise and Domino tenon?
As you are already saving considerable time using the Domino joining over traditional methods, we suggest that you take care when gluing up to ensure a good, solid joint. Simply squirt glue in the mortise and coat the sides with either a q-tip or brush. Some prefer using a disposable flux or acid brush for this. Brush glue across the face of the Domino tenon and along the edge as well. The patented glue pockets on the face of the Domino tenon ensure good adhesion. Be generous with the glue, you don’t want a starved joint. On large pieces, for longer assembly time, you may want to try polyurethane instead of yellow glue. For hard to glue woods like maple, or for exterior applications, we recommend epoxy.
