Pro tip: I swapped from caulk to backer rod for my bathroom gaps
I was redoing the trim around my tub last month and kept fighting with caulk sinking into those deep gaps. Finally grabbed a roll of backer rod for $8 at Home Depot and stuffed it in first. Then the caulk sat on top perfect and didn't crack after a week. Has anyone else made the switch or still just layering caulk like I used to?
