How to Seal a Shower Window

Besides the drain and the shower head, the most important thing in your shower is the shower window. Without proper maintenance, you could suffer drafts, mold, and other water damage. Follow these easy steps to seal your shower window.

Step 1 - Choosing Your Caulk

Surprisingly, there are several types of caulk to choose from. The most widely available type is silicone caulk. It can be a fine choice when sealing a shower window, as it withstands extreme changes in temperature. Also consider blended caulk, which contains latex, acrylic, and silicone. It is good choice for indoor caulking jobs. You may also want to think about caulks that are made especially for kitchens and bathrooms, as they will certainly provide everything you need to seal your shower window.

Step 2 - Cleaning

Ensure that the shower window and sill are clean. If your window is dirty or dusty, the caulk will not bond properly to the surface. Also ensure that you dry the area thoroughly before attempting to seal it.

Step 3 - Applying the Caulk

Caulk comes in a tube. You must cut the tip to access it. Make a clean edge so that the caulk squeezes out uniformly in a manageable shape. When you are ready to apply the caulk to your shower window, place the end of the tube against the seam. Push down with an intermediate amount of force. Once you see the caulk come out of the tube, steadily fill the seam.

Step 4 - Smoothing the Caulk

Working quickly, take a small board or file and flatten the caulk, which may have come out in bursts. Make the caulk uniform for proper placement and a neat finish.

Step 5 - Drying

Let the caulk dry completely before you use your shower again. The best thing to do is leave the new caulk to dry overnight, then test it again before you use the shower. Touch the caulk. If it still feels soft or a bit sticky, it still needs time to dry. Wait until the caulk is hard to use your shower.
