How to Recaulk a Leaking Shower
A leaking shower will damage your bathroom walls, floor, and the adjacent rooms. It promotes harmful mold and mildew growth, which will trigger allergic reactions and other health problems. As soon as you detect a shower leak, recaulk it to prevent further damage. Follow these steps to recaulk your shower.
Step 1 - Purchase High-Quality Caulking and Tools
100% silicone caulking is the best caulking for bathrooms. It comes in a clear and opaque white formulas. Choose whichever type suits the decor of your bathroom best. Buy a caulking gun with a strong spring to neatly expel the caulking from the tube.
Step 2 - Remove all Existing Caulking from the Shower Area
Slice into the existing caulk around the shower arm with the utility knife. Move down the border between the shower tiles, wall, and tub. Once you have made a small cut, detach the rest in long strips with a gentle pull. Use the putty knife to scrape the remaining bits. Be careful not to scratch tiles or chrome fixtures.
Step 3 - Clean the Previously Caulked Area
Remove most the visible mold and mildew with a disinfectant cleaner. Rinse the area thoroughly with warm water, then spray the mildew stains with a mildew stain remover. Scrub the stains with a nylon scrub brush that will not scratch the tiles. Rinse the shower area once more and allow it to dry for 2 hours with the bathroom fan running.
Step 4 - Locate of the Leak
The leak will usually be near the top of the shower arm. It could also be trickling from the border between the edges of the tub and the tile walls. .
Step 5 - Apply the New Caulking
Load the caulking gun and cut a .25-inch diameter slice from the tip at an angle. Press the caulking gun handle slowly to expel the caulking directly around the shower arm, the tile edges, and the tub-tile border. Apply caulking to the tiled corners of the shower walls as well. Wearing your dampened rubber gloves, smooth the caulked bead with your fingers. Wipe away the excess caulk with a damp cloth.
Step 6 - Let the Caulked Seams Dry
Do not use your shower for a full day after caulking to allow the seams to dry and become firm. Caulking repels water best when it has solidified completely.
Inspect the caulking once a year and maintain it as needed. Springtime is the best time to take care of these issues because the humidity levels in the bathroom increase in winter as the shower steam hits chilly, dry winter air.
