Best Tub Caulk – A Buyer’s Guide

Extension Tube

Many caulk manufacturers pack their caulks in tubes with a special pointy extension you can use to apply a layer of caulk directly to the area of your interest, so to speak.

This represents a useful addition to the overall design of the bottle, because it means you won’t have to buy additional spraying guns or anything of the sort. All you need to do is squeeze the tube gently as you would a tube of toothpaste, and the caulk will start coming out of it in no time.

Mold & Mildew Resistance

When it comes to the bathroom hygiene. One of the most prominent problems would represent the accumulation of mold, mildew, and other moisture-related pollutants. To ensure your bathroom will be free of this nasty stuff. You may want to look for a caulk that’s got something like ‘mold resistant’ printed on its label.

While the floor and the walls you’ll have to take care of yourself. The grout lines and the area between the bathtub and the wall will be completely free of mold if you use any of the mold-resistant caulks.

Waterproofness

Other than ensuring your caulk won’t fall victim to a rampant mold overgrowth in the bathroom, what you also want to make sure is that no moisture can penetrate beneath the caulking line and so compromise its shape or stability.

Similarly to the mold-resistance situation, the waterproofness of a caulking means represents another parameter you need to take into consideration before buying a caulk.

Non-Flammability

Although a spontaneous combustion isn’t necessarily a tangible risk for bathrooms. Certain chemicals used in cleaning solutions can be flammable, and the same goes for caulks.

Now, this fact causes a potential problem if you use hair dryers or other electrical contraptions in your bathroom. An errant spark sets off an otherwise normal-looking strap of caulk. So, to ensure this doesn’t happen, the manufacturers of these caulks have come up with special caulk formulas that make these non-flammable. So you won’t have to worry about your caulk catching fire any time soon.

Odorless Mixtures

Last but not least, it’d be important to mention that many caulks tend to smell pretty badly, so it’s quite a wonder when you find one that doesn’t.

If the smell is a big factor for you, try to find a caulking product that says ‘odorless’ on its label, or that has some specific fragrance added to it to mask the smell of the chemicals.

Frequently Asked Questions

  • 1) What is a good caulk remover?

There are many different caulk-removing products out there on the market, some of them in the form of a gel and some of them in the form of a paste. Products such as the 3M caulk remover, or some types of contractor’s solvents will do the trick just fine. (Of course, if you have found some other product for this purpose, there’s no reason this one wouldn’t function just as well.)

The bottom line is, these caulk removers represent the first step for removing the caulk altogether. If you get a good caulk-remover, the other parts of the task will be much easier to pull off.

  • 2) Do you need to caulk around shower fixtures?

Since caulking is a procedure that should be done in any spot, where there’s a danger of mold forming or water damage. The areas around shower fixtures would too benefit from some good caulking.

The thing is, the higher the water resistance in an area, the more it will be able to withstand constant exposure to moisture.

  • 3) Can you caulk over grout?

While the caulks we’ve described in the entries above are all excellent for protecting the surfaces you apply them on, when grout is in question, the story is a bit different.

You see, if the grout between the tiles has been compromised, your best bet would be to replace the old grout with some new grout, rather than filling the gap with caulk. (Or, worse still – apply caulk directly onto the dodgy grout lines.) So, if you want to protect your grout lines because the old grout is damaged, clean out the line thoroughly and then replace it with some more grout.

  • 4) Can I caulk over old caulk?

You can, but it’d be better if you could completely remove the old stuff and clean the area before applying a new layer.

The thing is, if you want to put a new layer of caulk over some old caulk, this new layer has to be thicker and wider than the old one, so that it can stick to the wall around it. Also, you have to make sure that the old caulk is not greasy or that it doesn’t have any oil on it, because in that case – the new caulk just won’t stick to it.

  • 5) Can I caulk over mold?

Technically you can, but don’t do it, because then you’ll trap the stinking mold underneath the new layer of caulk. It will become impossible to remove it without removing the caulk itself.

The thing is, mold represents one of the least desirable occurrences in your bathroom, so before laying down any caulk, make sure to clear it all out.

Final Verdict

All in all, caulking your tub can be an excellent way to preserve both the tub and the walls surrounding it, as well as to ensure that no mold or mildew will form in it after a while. We hope this article helped you find the optimal caulking product for your needs and we wish you a merry and hassle-free purchase.
