Caulking a shower is simple! If you notice the shower caulk is lifting or showing signs of fatigue, it’s time to re-caulk! Our simple how-to guide takes you through re-caulking a shower, step by step. Learn everything you need to know about best practices, and get your shower sparkling like new in no time!
If the caulk in your shower is beginning to lift, is showing signs of mold, or is broken, water will begin to penetrate into the walls, eventually causing major damage. Ignoring cracked or moldy caulk lines will only cost you more time and money in the long run. Knowing how to re-caulk your shower is the best way to preserve your home — and your wallet.
Before you get started, here’s a list of what you need:
- box cutter
- silicone caulk remover or mineral spirits
- joint scraper
- painters tape
- silicone caulk
- caulking gun
- gloves
- old cloth or paper towels
- smoothing tool
First, make sure the old caulk is removed, and the surface is clean and dry. Here are tips on how to remove old caulk bead.
- To strip the caulk bead, carefully run your box cutter down the middle of the caulk line. Avoid scratching the shower with the blade.
- Pull away the old bead with your fingers.
- Remove remaining residue with a joint scraper. For stubborn areas or any remaining residue, use a silicone caulk remover or mineral spirits to either to soften the caulk or remove the residue.
- Clean and dry the surface well before re-caulking.
Now you’re ready to start caulking the shower surround.
- Tape your borders with painters tape for straight bead lines.
- Prepare the caulk gun or applicator, according to package instructions.
- Apply the sealant in a smooth, even movement. Start in the corners and work your way out. Maintain a 45-degree angle and even pressure on the application trigger.
- Smooth the bead with a gloved finger or smoothing tool to remove excess caulk.
- Remove the tape carefully, and let the caulk dry.
