Do you need to learn how to caulk a bathtub?
Maybe the old sealant is moldy, peeling, or just nasty? This video could help you remove and apply a new bead of caulk without having to redo it multiple times.
Hey there, this is Jeff with Home Repair Tutor. I’m sharing this video because one of our awesome community members Lisa D’Amore asked me how to replace caulk in a bathtub.
Plus, I had to recaulk a bathtub in one of my rentals. Here’s that story: the home had an acrylic tub that flexed and as a result the caulk separated from the bathtub and surround.
What can you do to make sure the new caulking stays put?
Here are some tips:
1. Use a caulk meant for bathrooms
2. Remove all the old sealant, I MEAN ALL OF IT
3. Ensure the surfaces are clean and dry
4. Fill the tub with water
5. Apply caulk and shape it with caulking tube
6. Smooth bead with wet finger
If you follow these tips you’ll increase the odds of a good result.
I use DAP 3.0 because it’s 100% waterproof and has Microban in it which helps prevent mold.
But let’s be honest, mold will grow on anything that is organic. So if soap or dead skin cells (GROSS) land on DAP or any other caulk it’ll likely accumulate mold or mildew. At least the Microban will help deter this a little.

I recommend caulking when the weather is on the dry side. If it's rainy and muggy, takes longer to cure (lose its tackiness). I also like to blow dry into the space between tiles and tub, high heat. Get at any moisture that might be pushed back behind the caulk. (Do this before filling the tub, since you don't want to drop the dryer into the water.)
Caulk that tub spout while ur at it
I have caulked a lot of tubs in my day, but never thought about having water in the tub while the caulk is drying. Very good tip!
Lotta negligence in this video
The water in the tub is a priceless tip. Thank you.
I don't know where my husband got this idea. But after he removed old caulk and gunk from between the tub he used a solution of baking soda and vinegar. He pushed it in deep into the gaps. Then rinsed off and waited until totally dry. He used to use this same solution on his toenails and cured himself of foot fungus.
The last caulk job he did was eleven years ago and now its time. He passed away and I will try to do it with the help of this video.
P>S> why doesn't the manufacturers of caulk have a tip to put on it after one is finished. Sometimes and I don't know why the caulk continues to drlip……..also the ends get dry and have to be peeled off.
Thank you so much for these tips. I have a project to do while my husband is on his business trip, and the family is on quarantine during this time.
denatured alcohol is essential for this.
Can this also help for bathroom sinks ?
