Small cracks and spaces around your sanitaryware, such as toilets, sinks, bathtubs, and shower trays, can be a reason for the growth of mould, odor, and germs. These cracks can also make your bathrooms look ugly. You cannot use regular silicone sealants to fill these cracks as they don’t possess waterproof properties. Instead, you need a toilet caulk that is specially designed to serve this purpose. Even if you don’t have a toilet flapper you can easily get help from these caulks.

How to pick the best toilet caulk?
Even though all toilet caulks look similar, most of the available ones in the market will not be a good investment. Therefore, here we have a small guide that can help you buy the best toilet sealant for your bathroom –
One of the main advantages of using a toilet caulk is that it protects small cracks by preventing mould growth. Therefore, you need to ensure that the product that you are buying possesses anti-mould properties. If it doesn’t, then you will end up replacing your caulk every couple of months or so.
Most adhesive weakens out when exposed to sun, heat, or water. Buying such sealants is a waste of time and money as you might end up replacing and fixing them again and again. Therefore, make sure that the sealant you are buying is waterproof as well as capable of serving in different weather conditions. You can use any toilet tank cleaner on this caulk, it won’t lose the glue.
Volatile organic compound or VOC content refers to the toxicity of a sealant. Higher VOC concentration can be harmful to humans, and therefore, you should always consider buying a toilet caulk with as low VOC content as possible. The good thing is that most home-use sealants have very low VOC content than those available for industrial usage.
However, some sealants, such as polysulfide sealants, have a higher amount of VOC content. Therefore, you should avoid buying this type of sealant.
Some sealants, such as silicone ones, tend to leave stains when applied to materials such as white marble and stones. When buying a sealant, make sure that you pick the right product suitable for the substrate. You can also consider buying a toilet caulk that has a similar color to your toilet’s interior.
Another thing to consider is the quality of the product you are buying. Make sure to buy a sealant that is capable of both indoor and outdoor usage. So that, in case you have some extra adhesive, you can use that for other purposes. If you have a portable car toilet, you can still use these caulks for the same reason on your toilet.
Flexibility and hardness
Even though your toilet will be fixed on the floor, it shakes a bit when you sit on it. If your primary concern is to prevent seepage of water into the cracks around it, the best toilet caulk for the toilet base would be the one that has some flexibility.
However, note that when the flexibility increases, the hardness of the sealant decreases. I recommend buying a sealant for the toilet base that has proper hardness with sufficient flexibility.
Ease of application
The next thing that you need to consider is how easy it is to install the caulk around your toilet base. Incorrect installation would lead to the failure of the seal. You can find several toilet brushes for the cleaning job.
Best Toilet Caulk of 2021

Though different types of sealants can be used to fill the crack around your toilet, silicone sealants are considered the best primarily because silicone sealants offer quite flexible and sturdy adhesion.
What is the best way to caulk the base of a toilet with a caulking gun?
- First of all, remove any old caulk.
- After that, clean the area where you are going to apply sealant with the help of a dry brush.
- Apply masking tape around the area where you want to apply the caulk so that the caulk won’t scatter around your floor and look messy.
- Lastly, apply the sealant properly, press it firmly with your finger, and remove the masking tape.
- Let it dry for an adequate time.
What is the best caulk for securing a toilet to the floor?
The best caulk to secure your toilet to the floor depends on a bunch of factors. However, if your budget allows, go with the UniBond Anti-Mould Sealant, as that is one of the best toilet sealants you can buy online.
Among all the products mentioned above, I would recommend buying UniBold Anti-mould sealant to caulk around your toilet base. It is the best sealant that you can buy right now.
