why miter saw moldings at 45 degrees

[evoline]

Hello,
I wonder why baseboards are mitered at 45 degrees; at outside corners, it looks nicer at least, but on a long wall where you have to join them??

Thanks

Well, it's simply because it usually looks best. Of course, it depends on the type of baseboard you have. If you have a baseboard that is almost rectangular in cross-section, you can make a butt joint, but if you have one with a lot of profile, it would look very strange otherwise.

A 45° joint on a moulding is much stronger because the glue (used in the joint) better withstands the wood's natural movements compared to a butt joint. This also means that the cabinetry painting done over the joint will remain crack-free.

A 45° joint on a molding is much stronger because the glue (used in the joint) resists the wood's natural movements better than a butt joint. This also means that the carpentry painting you do over the joint will remain crack-free.

How do you glue the molding, before installation or simultaneously with the installation?

When mounting the trim on the wall.

I glue while setting up, works great.

How do you glue the strip, before mounting or at the same time as mounting?

At the same time as mounting. Otherwise, you can bet that the joint will crack when the nail is driven in.

aha ok, so you glue at the miter joint.
I've only nailed/screwed the molding into the wall each time, without glue.
And I can say that they usually barely fit each other, not sure if it's the saw or my eyes that are the problem
Then used some caulk to make it look nicer...
