How to Replace Caulk Around Tubs and Sinks
One thing comes to mind regarding sinks, tubs and showers- WATER, and lots of it! Caulk is applied around the edges to keep the water from accessing areas it shouldn’t. Replacing this protective barrier is essential every once in awhile.
Water Damage
Water leaking behind walls, under sinks and around faucets can wreak havoc on the wood and insulation. Small amounts of water leaking in these areas can run up thousands of dollars in repair and replacement costs in a short amount of time.
Mold
Areas of the home that are prone to moisture exposure, such as kitchens and bathrooms, are prime targets for mold growth. Allergy and asthma sufferers are sensitive to mold spores and can react by experiencing breathing difficulties.
Mold tends to build up in the microscopic cracks of dried caulking and leave it looking dingy and dirty. Areas damaged from water leaks due to missing or broken caulk provide the perfect environment to sustain mold. You definitely want to safe guard your family from this health concern.
Replacing Latex Caulk
Latex caulk is the easiest type to remove and replace. It cleans up easily with water and you do not have to feel rushed to get the job done. There is plenty of time between application and drying to ensure that the job is done neat and correctly.
- Remove the old caulk by running an old credit card along the border between the caulk and adjoining surface. Pull the pieces free and discard. Continue this along the length of the caulked joint needing replaced.
- Mix 2-cups of water with 1/2-cup of chlorine bleach. Scrub the area well using an old toothbrush. Allow an hour or two for drying.
- Load a caulking gun with a tube of latex caulk. Trim the edge open at a 45-degree angle to aid in applying it to the surface. Pull the trigger until a smooth line of caulk comes out of the tip.
- Apply a bead of caulk slowly along the joint. Wet your fingertip and run it along the top of the bead to smooth it. Allow the caulking material 24 hours before using the sink, shower, or tub.
Replacing Silicone Caulk
Silicone caulk is a little more difficult to work with, but the waterproofing quality can’t be beat. The key to successfully removing old silicone caulk is patience. Applying the new bead has to be done quickly because silicone has a tendency to set very fast.
- Remove the old silicone caulk using a sharp utility knife. Carefully slice the bottom of the silicone with the blade at a 90-degree angle to the wall.
- Bring the knife up to a 45-degree angle and slice down into the topside of the silicone caulk line. Pull the caulk free from the joint.
- Run a razor blade carefully along the areas with remaining caulk. Hold the blade flat against the surface to avoid scratches.
- Mix 2-cups of warm water with 1/2-cup of bleach and scrub with a small brush. Let the area dry completely before caulking.
- Load a caulking gun with 100 percent silicone caulk, trim the tip at a 45-degree angle and apply a thin bead to the open joint. Stop every few inches, wet your finger and run it along the silicone surface to smooth it. The silicone will begin setting if you wait until the entire bead is applied. Give the caulk a day to dry before using the kitchen or bathroom.
