Top Picks : 3 Best Tub Caulk

5 Best Bathroom Sealant Reviews

Not all tub caulks are created the same, and since there are a lot of situations that call for tub caulk, there are some considerations that you need to make before buying tub caulk.

1. Rubber Adhesive Sealant Caulk by Flex Shot

Flex Shot Rubber Adhesive Sealant Caulk, 8-oz, White (2 Pack)(Mildew Resistant)

Something that turns most away from applying any caulk to any given surface is the necessity to use a caulk gun. A lot of people do not know how to use a caulk gun properly and this can be a problem.

Flex Shot’s tub caulk solves this problem. It comes in a squeeze bottle and applying it is very easy. You do not need to load up a caulk gun or anything to use it. This ease of use is one of the best things about it.

Another nice thing about Flex Shot’s caulk is that it comes with an extension tube. This tube will allow you to reach areas that are difficult to reach. These are areas that you would normally not be able to reach even with a caulk gun.

Filling big cracks and holes is also not a problem with Flex Shot’s tub caulk. It expands on contact which allows you to use it to fill cracks and holes that you might not have been able to fill with other kinds of caulk.

There is only one real setback to Flex Shot’s caulk and that there are only eight ounces in the tube. This can limit your use, and if you need tub caulk for a large-scale project, you will need to look elsewhere.

2. Kitchen and Bath Silicone by GE

General Electric GE360 Kitchen and Bath Silicone I Caulk, 2.8-Ounce, Clear

A good amount of tub caulks have multiple uses, but when it comes to sealing things in the bathroom, chances are good that you will want to need a tub caulk that specializes in sealing things in the bathroom.

GE’s Tub Caulk is designed for sealing things in a bathroom, and the reason that it is specialized as such is because it adds silicone as a sealant. This allows it to adhere to everything in a bathroom where most of the “all purpose” tub caulk would not be able to.

Another reason why GE’s tub caulk is good for bathroom use is because it is waterproof. A good amount of tub caulks are not waterproof and this is why many of them are not suitable for any given bathroom. For places that contain a lot of steam and water like a bathroom, you’ll notice a difference with these waterproof properties.

The only thing about GE’s tub caulk that doesn’t make it perfect is that it does not have an extension tube. You will struggle with hard-to-reach areas when using GE’s tub caulk and you will encounter them a lot even in a bathroom.

3. 100% Clear Silicone Bathroom Caulk by Gorilla

Gorilla Waterproof Caulk & Seal 100% Silicone Sealant, 10oz Cartridge, Clear (Pack of 1)

One of the biggest issues with tub caulk across the board is that it is one universal color: White. This means that if the things that you apply it to are not white, it will severely compromise how the surface looks. And as you probably know, there are many surfaces that you can apply caulk to that are not white. This is an issue that is rarely solved.

Gorilla’s tub caulk solves this issue by being clear. This makes it possible to be applied to any surface without sacrificing any kind of aesthetic value to the surface. Very few tub caulks contain this trait, and that is what makes it so valuable.

Even if the surface contains mold or mildew, you will be just fine with Gorilla’s tub caulk. It completely resists both substances, which is also rare for most tub caulk and is another very good thing about it.

There is only one thing about Gorilla’s tub caulk that you might want to look out for, and that is that it is not as adhesive as other tub caulks. This is perhaps due to the fact that it is clear. The clear substance of Gorilla’s tub caulk makes it a little less adhesive.

4. Polyseamseal White Tub and Tile Sealant by Loctite

Polyseamseal Tub & Tile Caulk, White, 5.5 oz.

A lot of tub caulks will not resist scrubbing. You could apply it to whatever you want, but as soon as the surface gets scrubbed, some of the caulk will be removed, and this can be troublesome especially if you just applied tub caulk to any given surface.

Loctite’s tub caulk solves this issue in a big way. The sealant inside of the caulk is water tight and paintable, which means that as soon as you apply it to a surface, the caulk will not be scrubbed off. This is very useful when it comes to sealing surfaces that are located outside, where they can be exposed to elements that could damage the caulk.

Another good thing about Loctite’s tub caulk is that it is very strong when it comes to sealing in and of itself compared to most other tub caulks. Again, this is very useful when it comes to sealing surfaces outside, since the heat from outside can loosen up some tub caulks. You will not experience that with Loctite’s tub caulk.

The one thing that is questionable about Loctite’s tub caulk is that it contains only 5.5 ounces of caulk in its tube. This is a little less than what is contained in the tubes of other tub caulks.

5. Rubber Adhesive Sealant Bathroom Caulk by Flex Shot

Flex Shot Rubber Adhesive Sealant Caulk, 8-oz, Almond (Mildew Resistant)

A good amount of tub caulks are white in color. While this is not a bad thing with most surfaces that you use tub caulk on, there are some surfaces that call for a different color of tub caulk. It can be difficult to find tub caulk that is not white, since white is the most popular color of tub caulk.

Fortunately, Flex Shot’s tub caulk solves this problem with its almond colored caulk. While about half of surfaces that require tub caulk are white in color, the other half are almond in color, and it can be useful to have some almond color tub caulk on hand. This is what Flex Shot’s tub caulk offers.

It can be difficult for most tub caulk to reach certain corners where you might need it the most. Fortunately, Flex Shot’s tub caulk has this handled. It comes with an extension tube that is able to reach places that you just could not reach without it. This makes it very useful for bathrooms or kitchens, where these hard-to-reach spaces usually exist.

The fact that Flex Shot’s tub caulk can expand and contract is well-intentioned, but this does take some practice to master. What usually happens is that the expanding caulk will leave a mess all over the surface you have used it on. Be very careful when you apply it.
