Durable top coat for MDF worktop / workbench

Would pine or MDF baseboard better handle humidity fluctuation?

MDF may be marginally more stable, but in my extensive experience it's far too fragile to be used for house trim. I wouldn't install it if it was free. It dents and scratches like nothing. If you're ...

Fill groove in MDF door

Depends on size. For significant blems, I'd try wood putty, handling it as if it were joint compound. If that didn't work, I might just give up and actually use joint compound... However, remember ...

Do solid core doors reduce sound more than hollow-core doors?

For the best match, cut a thin piece of the same MDF material to fit, and glue it into place with wood glue. MDF is very easy to work with so this would be relatively easy. If the fit is good enough, ...

Is there a reasonable substitute for nail guns when installing baseboards?

You could get something called a trim screw. They also sell them in white if you wish to match the color and not cover the hole with putty. It sounds like you don't feel comfortable with trim nails ...

Joining MDF shelf to extend length of spare pieces
