Reply to comment by ender4171 in Is no more nails glue acceptable for attaching wood together for shelving? by ThatCraftyDragon

Out of curiosity. Would there be a situation when making a paste of wood glue and sawdust be desireable? Specifically in regards to “filling” small gaps, I wonder if it would be stronger or weaker.

That's a great way to fill old screw holes, like say you strip a screw or something.

But it's not going to bond a good joint that way. Wood glue works best when spread evenly between two square faces, and clamped with sufficient force to make it slightly seep out along the length of the joint.

And ideally avoid endgrain or anything with finish on it- you’re not gonna get wood glue to stick to something painted, clear coated, waxed or pre stained. I can’t tell from op’s description but if it’s gluing new pieces to prefinished, use a construction adhesive or nail in cleats to support the shelf

That's a good (and common) method for filling things cosmetically, but would not be a good structural bond.
