Using wood dough filler is a great way to fix small gaps in your woodworking projects. George Vondriska shares his tip for creating seamless repairs of small voids with a shop-made wood dough filler made from yellow glue and wood dust. A WoodWorkers Guild of America (WWGOA) original video.
I’ve tried wet sanding with shellac as an alternative. Yellow glue is unstainable in my experience.
All wood fillers must be sanded to original wood and a little below. The solvents in putties seal the wood to some depth. Some solvents will actually raise the wood a little bit.
Nice tip, but if you were going to stain your project, doesn’t the glue seal the wood somewhat and make for a blotchy looking color?
