How to Caulk the Base of a Shower
- 1). Remove any old caulk, if necessary. Look online for caulk removal instructions. This can be a lengthy process, so budget your time as necessary.
- 2). Thoroughly clean and dry the area to be caulked. This is a vitally important step. Any moisture, old mildew, soap scum or old caulk can prevent the new caulk from sticking to the surface, causing leaks and peeling caulk in the near future. This is particularly true if you removed silicone caulk. Use a cleaning agent that doesn't contain ammonia and is made specifically for soap scum first and use a bleach and water mixture to kill any mold. If you don't properly clean and dry the shower, you will be caulking again in a few months.
- 3). Choose a caulk with anti-mildew agents added. Some new caulks have lifetime warranties against mildew growth. You can also choose colored caulks for added style.
- 4). Mask off the area on each side of the area to be caulked. Use painter's tape for a very smooth, straight and professional job. Place a straight line of tape about 1/8 inch from each side of the edge or seam to be caulked.
- 5). Cut a small hole at the tip of the caulk tube. Make sure the hole is not too big; one of the biggest mistakes people make is using too much caulk. You can always cut the hole bigger.
- 6). Squeeze a small bead of caulk along the edge or seam. You want an even line of caulk along the entire edge. Use a caulking gun, or just use your hands, to apply steady pressure.
- 7). Smooth the caulk with a caulking edge or other flat, rounded object. Many people use the tip of their finger. You want the caulk pressed into the edge and smoothed. If you masked the edge with tape, remove the tape now, before the caulk dries.
- 8). Wipe off any excess caulk and let it dry for 24 hours before using the shower.
