Are you fed up with mold and mildew in your showers and tubs? Showers are always damp and mold loves dampness. It starts breeding at the corners and from there, it quickly spreads throughout the surface. It also penetrates into the tile structure through gaps and porous grout. Many of you use caulk at the corners of your showers and tubs to prevent mold breeding. But this caulk starts peeling or cracking in a few months and so you think of recaulking. You get into a constant loop as caulking, in the first place, is not a permanent solution. Here, we shall discuss a permanent cure for shower corners and tubs. If interested, read further to know about the best caulk substitute for showers and bathtubs.

What Causes Deterioration of Shower and Bathtub Caulks in a Few Months?

  • Most caulks are made from silicon, acrylic or latex. These materials start peeling off in wet settings and as the shower is constantly damp, caulking proves to be a failure.
  • If the weather conditions are too dry inside, caulk shrinks and cracks, forming crevices and gaps in this structure. This damaged caulk cannot seal your shower corners securely after cracking and this leads to mold and mildew breeding.
  • Mold which starts forming on the gaps, quickly spreads on the caulk also, which further deteriorates it.
  • Acidic cleaners also damage the shower caulk.

If not Caulk, then What is a Better Caulk Substitute for Sealing Shower Corners?

Caulk is not suitable for sealing shower corners. If your caulk has become dirty and moldy, you can clean the caulk in showers, but you cannot prevent its cracking or peeling.

An epoxy resin sealer proves to be the perfect substitute for replacing caulk in showers as it renders a permanent bond on the corners. Our new age epoxy resin filler renders a sleek and natural appearance to the shower caulk, enhancing the overall appeal. These are not bulky like caulk and also give a permanent fix to your caulking problems.
