Sometimes you want to spread glue evenly over a joint surface on your woodworking projects, and George Vondriska teaches you how one of the best choices for applying the glue just might be an old toothbrush. A WoodWorkers Guild of America (WWGOA) original video.
Shouldn’t you be wetting both surfaces with glue? I’ve found that this ensures full glue contact, and prevents a glue-starved joint.
This is a frequently debated topic, but in general with PVA wood glue it is not critical to wet both surfaces. You need to ensure adequate coverage on all joinery components, which can be accomplished with either method. If it increases your comfort and confidence to coat both surfaces, then by all means do so. I normally just coat one, and have never had a glue joint failure. (ZD: 3506)
