The Right Amount of Glue
With a little experience, you'll develop a feel for how much glue is just enough. Too little glue creates a “starved joint,” which will be weak. Too much glue makes a mess and wastes glue. With practice, you'll know just how much to apply. You should see a continuous line of small glue beads. When this perfect glue joint sets a little, you'll find it easy to scrape off the jelled excess, and you'll have very little cleanup to do.
Picking the Best Exterior Glue
Apply Tape to Control Glue Squeeze-Out
Glue squeeze-out soaks into the fibers of raw wood, leaving blemishes when you later apply the finish.The usual solution for this is to clean it off with a wet rag or sponge. But too much water around the joint can weaken the bond. It's better to stick down masking tape along both edges of the joint before gluing.The excess glue will then squeeze out onto the tape instead of the wood, and you can just peel the glue away when it's dry.
