The four pieces are assembled and the excess glue has been sanded away. Now we need to glue the four pieces together, but how do you avoid glue lines in the corners where you can’t sand later?
Plastic will keep the boards from gluing to the sink, but how do you keep the glue out of the edges? Masking tape.
Blue masking tape can be placed right up to the edge of the wood joint, then cut off with a sharp knife.
Cutting it instead of tearing it ensures that the edge of the tape is flush up against the edge of the wood with no gap.
The goal is to completely replace the wood in the corner with tape, that way any glue that squeezes out of the joint in the gluing process finds its way onto the tape and not onto the wood.
With the first piece done, it is time to repeat the steps on the next piece of the corner.
If you are lucky and the tape meets the edge of the wood perfectly, you are finished!
If the tape is not perfect, you will need to cut a scribe line into the tape so that it can be peeled off.
Use the tip of a sharp knife to cut the tape on the wood. Don’t worry about scratching the wood as this mark will be in the very corner of the wood, so it won’t show.
With the line marked, simply peel off the excess and be presented with your own custom cut masking tape line.
The tape peels off easy with the tape cut all the way down to the wood with a sharp knife.
Now yo u have the corner protected to perfection. The last step is to fill the wood joint with wood glue and compress the joint with formidable clamping pressure!
Once the wood is clamped up, the excess wood glue will squeeze out. Take a paper towel and wipe up the excess wood glue. Once it is all wiped up, simply peel off the tape and be finished with it. You want to pull the tape off while the glue is still wet or the tape itself will get glued to the wood by the glue, giving you a whole new level of frustration!
The glue that squeezes out on the top of the furniture doesn’t matter because it can easily be sanded off. The glue in the corner is the troublesome part and having tape there will make your life easier.
