A Tip To Protect Your Project From Glue Run-Outs

Whenever creating glue connections among two pieces of wood, one need to guard against excessive glue run-out, particularly when the finish on the woodworking project is going to be a stain or other clear finish.

Why?

Any glue that runs out onto exposed surfaces will most likely fill the pores of the wood, which will stop the stain from seeping into those glue-filled pores. This will appear as splotches in the stain of the finished project, which will likely be fairly obvious to anyone searching at the piece. Naturally, attempting to wipe up the glue as soon as it runs will assist, but doesn’t always get all the glue out of the pores. Moreover, you run the risk of spreading the glue as opposed to choosing it up, making the dilemma worse.

One more technique is to enable the glue to dry, then try to gently cut or scrape it out. Once once more, this is not likely to get all the glue out of the wood’s pores, leaving behind the same finishing difficulty.

There is a basic trick 1 can use to nearly get rid of the problem, particularly on mortise and tenon joints. Following dry-fitting the tenon into the mortise, prior to applying any glue, line all corresponding edges of the mortise piece and also the tenon piece with masking tape or blue painter’s tape. By applying tape to all surfaces adjacent to the joint, any glue that runs out will likely be squeezed out onto the tape and not the bare wood surrounding the joint.

Bear in mind that this isn’t a license to “over glue” the joint. One should still be cautious to utilize just sufficient glue within the mortise and tenon joint to hold the joint, but not so considerably that it’ll squeeze out excessively.

Following the joint has been clamped and allowed to dry, merely peel off the tape and your bare, but protected wood along the edge of the joint will probably be clean and ready for staining.
