How to Prevent Mold on Tub and Shower CaulkBy: Danny Lipford
I’m constantly replacing the caulk between my shower walls and floor due to mold. How can I prevent mold from forming on the caulking in my shower? -Bill
Any time you put caulking in a high moisture environment, such as in a shower or tub, the result is usually mold and mildew. One thing I always recommend is to use 100% silicone caulking in a tub or shower, rather than acrylic caulk. The caulk you use in a tub or shower should also contain a biocide to prevent mold from forming.
While several manufacturers have come out with pretty good mold resistant caulk, I’ve really been impressed with GE Silicone II* K/B Supreme.
Advantages of GE Silicone II* K/B Supreme include:
- Flexible: 100% silicone caulking doesn’t crack or shrink and remains flexible over time.
Good luck with your project,
