4. Smooth

As soon as the seams are filled, dampen a lint-free rag or paper towel and press it into the joint with your finger. Pull it along the joint in one continuous motion to shape the fresh caulk into a concave bead. Immediately remove the tape, one strip at a time, taking care not to let it touch any of the fresh caulk. Then go back and smooth the bead again to eliminate the tiny ridges left by the tape. Wait at least 24 hours for the caulk to cure before using the shower or bath.
