What The Caulk Man!
When you caulk a bathroom tub shower take care and do these steps to make it look great, and keep moisture and mold out.
1. Remove the old caulk using a straight edge and a painters multi-tool. This may sound obvious, but a lot of people add caulk on top of old caulk which is bad. Get deep inside the seam to remove as much off the old caulk as possible. Gently scrape away any excess on the tub or shower surface. Wipe and clean up the the debris.
2. Using a cleaning agent like Ajax or similar scrub the seams and area that you're going to caulk. Add just enough water to wet and wash the surface. Use an old tooth brush and handle brissle brush and scrub deeply into the seams. Then wipe it out using towels and the painter multi-tool. Add a little more water and continue cleaning with the rags and equipment until it's completely clean. When all the excess old caulk, dirt, mold and grime are removed and the surface is smooth you're then ready for the next step.
3. Using a sprayer filled with a mixture of water, vinegar, and bleach spray the seams to kill off any excess mold. Repeat the disinfecting cleaning effort as you cleaned in step #2. Completely dry the surface and seams with towels and possibly a blow dryer.
4. Using a caulk gun, good silicone caulk, paper towels, wet rags, and a caulking tool apply the new caulk into the seams one section at a time. It is critical that you only work a small section at a time. Only move on to the next section after completely applying, smoothing, and cleaning the caulked seams. I use rubber caulk wedges, that have various angles and curves, for smoothing out the caulk. I smooth out the caulk over a short distance wiping the excess cauk off the rubber wedge and onto a towel. Then I continue until the section is finished. I immediately scrape any excess caulk above, below, or next to the new caulked seams to remove any thin layer of caulk from the tub or tile. I then wipe the same area with a wet rag. Try your best to never touch the newly applied caulk when cleaning around it. If you screw up just start over again. When you do this step well the new caulked seem will look, smooth, clean and beautiful.
5. NEVER use you bare finger to apply the caulk. Your finger has oils and will leave marks where bacteria and mold can quickly develop. It's also very sloppy.
6. Move from section to section repeating #4 until you are finished. You are performing quality work when you use a bunch of towels to clean off excess caulk and the seams look smooth, aligned, and consistent. When finished wipe the area one last time with a damp clean rag to remove and excess streaks or spots you didn't catch. Let it cure (dry) for the recommended time on the caulk tube.
With the little patience and care you applied to re-caulk your tub and shower you will be rewarded with awesome results. As a bonus, keep it dry by leaving the fan on for about 15-20 minutes after your shower and it should stay mold free for a long time!
