Can Flex Seal Be Used On Shower Floor?

uses of flex seal

Cracks in the shower floor are inevitable, but repairing them on time is essential to avoid further damage.

Fortunately, Flex Seal’s product (Flex Shot) can be used as a measure to prevent water from seeping through the cracks and causing more damage.

Due to its water-repellent and mildew-resistant properties, it works to provide a water-tight seal that prevents leaks.

Flex Shot also comes in a variety of shades (to match your bathroom), and it’s an excellent alternative to a silicone-based sealant that can be used to fix shower floors and for a variety of other bathroom applications.

How to Use Flex Shot On Shower Floor?

Flex Shot is easy to apply, and you have a choice of four colors: white, black, clear, or almond.

So, regardless of your bathroom color scheme, you’ll be able to find a match.

One can Flex Shot will cover about 40 to 100 linear feet, so if you buy a pack of two (usually available at Amazon and other stores), you can work on any project, small or large.

1- Remove Existing Caulk and Clean

To apply, start by removing the existing caulk you have using a caulk remover and razor scraper – never use Flex Seal products over old caulking.

Once you have removed the caulking on the shower floors, thoroughly clean the cracks with soapy water and a brush to remove any dirt, mildew, or debris.

Use vinegar or rubbing alcohol cleaner if required, as this will help the new Flex Shot sealant to adhere better.

Let the area dry completely before moving on to the next step. Flex Shot will certainly work on wet surfaces, but it works better on dry ones.

2- Apply Flex Shot to the Cracked Shower Floor

The Flex Shot comes with an extension tube that you can screw onto the end of the applicator. This is helpful for hard-to-reach areas, like corners.

You can cut the extension tube to your desired thickness: cutting close to the base dispenses out a thicker line of Flex Shot, whereas cutting towards the tip would help make a thinner line.

When you want to use Flex Shot, press down on the nozzle and evenly fill the area you are caulking.

After you finish applying the Flex Shot sealant, use your index finger to smooth it out so that it fills in every nook and cranny.

Once you’re done, wipe away any leftover product. Allow the sealant 20 minutes to dry before touching it, but give it 48-72 hours to cure fully.

After you’re done, release some of the product out of the end of the tube so that a plug forms.

This will keep your Flex Shot from drying out when not in use. If you ever need to reuse it again, just remove the plugs before application.

Advantages and Disadvantages of Flex Shot?

Unlike silicone, a type of synthetic rubber that looks and feels like real rubber when dried, Flex Shot is a liquid rubber product that solidifies as it dries.

Flex Shot and traditional silicone caulk are both dependable for showers and bathrooms, but there are advantages and disadvantages to each option.

Therefore, it is necessary to consider the positives and negatives before deciding which one better suits your needs.

Benefits

Flex Shot lasts much longer than your typical caulk or silicone sealant with less cracking over time.

It also comes with easy-to-use applicators built in, as opposed to caulk and silicone sealants which would normally require a caulking gun.

Drawbacks

Flex Shot may not be the right product for you if black mold is present in your bathroom, as it does not include features to fight this common problem.

Also, because Flex Shot is very noxious, please make sure you have ventilation set up before using it.

What’s the Difference Between Flex Seal and Flex Shot?

Flex Seal and Flex Shot both come from the same product line, with Flex Seal coming as either a spray can or in buckets.

It looks like thick liquid rubber while wet but dries to form a thicker seal.

Flex Shot is similar, appearing as a pressurized can of a rubberized caulk with an easy-use nozzle attached; this makes it much simpler to apply than its counterpart.

Although there is a difference, both these products work very well to create a waterproof bond on a variety of surfaces, including cement, concrete, tile, glass, plastic, aluminum, porcelain, wood, drywall, rubber, and others.

Just make sure the surface is clean and free of dirt and grease before you use them, to create a stronger seal.

The bottom line

Flex Shot (by Flex Seal Family of Products) is an excellent product for caulking showers and baths along with cracked shower floors.

Its easy-to-use creates a waterproof seal and lasts much longer than traditional caulk or silicone sealants. It also doesn’t require a caulking gun like some of its competitors.

One downside is that it doesn’t include features to fight mold, so if you have this problem in your bathroom, Flex Shot may not be the right product for you.
