Wood glue makes boards slide against each other like Bowser on a banana peel — and that’s a problem when you’re trying to keep them aligned.
But there’s an easy way to add some friction…
So you can keep boards in position and avoid a panic realignment after you tighten down your clamps.
All it takes? A bit of sandpaper — or some table salt.
Before clamping the boards together, rub a piece of sandpaper against itself above the glue you spread.
Make sure you rub the rough face of the sandpaper together. The granules will break off and scatter across the glue.
Even a little bit creates enough friction to keep the boards from sliding against each other as you tighten your clamps.
And since the granules are small, they’ll compress between the boards and won’t leave any gaps in the joint.
Feeling salty? You can do the same thing with fine table salt.
Sprinkle a bit over the glue-covered face or edge and you’re good to go.
This is a great tip for when you're gluing boards together at their edges or faces…
And can really take some of the stress out of glue ups.
