A little hack with Big Stretch Sealant to get this piece off trim straight with a crooked wall!

What happens here

Load a tube of paintable caulk into a caulk gun. Carefully apply a continuous, even bead of caulk along the top edge of the baseboard where it meets the wall. Also, apply caulk to any mitered corner joints or seams between baseboard pieces to fill gaps and create a seamless appearance.

Goal: Seal gaps along baseboard edges and joints with caulk.
