Hey guys, I'm in the middle of refinishing a oak hardwood floor in my rental property and I have a good amount of 1/16th gaps in between the boards. And a couple 1/8th gaps but not many. After sanding i have collected at least a gallon of super fine sanding dust and I have heard of a technique of making wood filler by mixing sawdust with glue. Have any of you ever tried this ? If so what kind of glue, what ratio, and did you add any water to make it more workable ? Thanks for any input.
