Currently renovating a kitchen in the summer cottage. Started last year with drywalling/spackling the walls and it looks good with one exception. In one place, the drywall meets a wooden beam, and the spackle has cracked there. The transition is completely smooth (there are no beveled edges like there are between drywall-drywall), so I can't apply any reinforcing tape.
Everything will be painted eventually. How do I prevent the joint from cracking?
