Caulking a shower is simple. If you notice your shower caulk is lifting or showing signs of fatigue, it’s time to re-caulk! Our simple how-to guide takes you through replacing and applying shower caulk step by step. Learn everything you need to know about best practices, and get your shower sparkling like new in no time!
If your shower sealer is beginning to lift, show signs of mold, or crack, water will begin to penetrate into the walls. That will eventually cause major damage. Ignoring cracked or moldy lines in your shower caulk will only cost you more time and money in the long run. Knowing how to apply shower caulk is key to preserving your home and saving money.
Before you get started, here’s a list of what you need for caulking a shower:
- painter’s tape
- shower silicone: Loctite 100% Silicone
- caulking gun
- gloves
- old cloth or paper towels
- smoothing tool
If you are removing old shower caulk and re-caulking a shower, you also need these tools:
- box cutter
- silicone caulk remover or mineral spirits
- joint scraper
If you are caulking a new shower and do not need to remove existing shower caulk, you can skip to the next section, “How to apply shower caulk.”
First, remove the old shower caulk and make sure the surface is clean and dry. Here are tips on how to remove old caulk beads.
- To strip the shower 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 applying new shower caulk.
If time is of the essence, you can re-caulk your shower in just one step. Loctite RE-NEW unites innovation and convenience and is the best shower caulk if your seals need a quick facelift. Just apply Loctite RE-NEW directly over your old shower caulk line, and you’re good to go!
Once you’re ready to start caulking the shower, follow these steps:
- Tape your borders with painter’s tape for straight bead lines.
- Prepare the caulk gun or applicator according to package instructions.
- Apply the shower caulk with a smooth, even movement. Start in the corners and work your way out. Maintain a 45-degree angle to the surrounding surfaces and even pressure on the application trigger.
- Smooth the bead with a gloved finger or smoothing tool to remove excess shower caulk.
- Remove the tape carefully, and let the shower caulk dry.
