My bathroom backsplash-to-wall junction was just re-caulked yesterday. (The old caulk was discolored and showing signs of mold.) But on one side of the countertop where there's a 3/8" gap between wall and backsplash, the new caulk was applied at a slightly lower level than the top of the backsplash, meaning there's a small area where water will pool on top of the caulk instead of draining back down onto the backsplash and countertop.
Question: can I just add more caulk on top of the now-dried other caulk, in order to raise the caulk level above the backsplash top so water will drain correctly? Or do I need to rip out all the caulk and start from scratch?
I'm using GE Max 5000 caulk if it matters.
