Flash Floor FAQ

FREQUENTLY ASKED QUESTIONS

How much can I repair with one Flash Floor cartridge?

Damaged concrete never has a consistent measurement. It could be 1 inch wide on one end and 5 inches wide on the other, or 3 inches deep on one end and 6 inches deep on the other. The best answer we can provide is as follows:

For cracks or control joints:

At ¾ of an inch wide by 1 inch deep, 1 cartridge can repair an average of 10-12 linear feet, or up to 106¼ cubic inches.

For voids, spalls, holes, etc:

1 cartridge can repair a void that is 8½ inches x 5 inches x 2½ inches or up to 106¼ cubic inches. For a visual, this is about the size of 2 common house bricks.

*These dimensions can increase or decrease depending on proper usage and installation of Flash Floor. Be mindful that you can lose Flash Floor in your repair to cracks or voids within the repair area. To prevent this you can create a "seal" as seen in this video: "Creating A Seal with Flash Floor"

How big of an area can I repair with Flash Floor?

There are no size restraints. In the 20 years Flash Floor has been on the market for repairing concrete, we have used it for repairing everything from hairline cracks to holes you could nearly fit a vehicle into.

What is the psi or strength of Flash Floor?

Just minutes after a repair has been made, Flash Floor cures to a similar strength as the surrounding concrete of 4500 psi.

What makes Flash Floor better than epoxy repair products?

Epoxies are simply hole fillers that don't bond to the concrete and become more and more brittle over time. They are difficult to work with, require more prep to the concrete, and smell awful.

Flash Floor is superior in all of these areas. It's very easy to work with, penetrates deep into the pores and bonds to the concrete, requires very little prep, has minimal odor, etc. You can read more information on Flash Floor vs epoxy here: Link 1, Link 2, and Link 3

Do I have to use an aggregate (sand) with Flash Floor?

No, but we highly recommend it. Adding an aggregate to your Flash Floor repair will do 3 things. 1) It will extend Flash Floor's volume (the amount you can repair) by up to double. 2) It balances the strength difference (balances the PSI) between Flash Floor and the concrete being repaired. 3) Adding the aggregate makes a stronger repair.

Can I use my own aggregate (sand) with Flash Floor?

Yes, just make sure the sand is 100% dry. We recommend a medium grain size. You can find washed and dried sand or medium sand-blasting sand at some hardware stores, which are both viable options.

Can I use Flash Floor in a Freezer, Cold Storage, or Cooler?

Yes, Flash Floor not only works great but is the best option for repairing concrete in Cold Storage (aka freezers & coolers). Just make sure your repair area is completely dry and keep Flash Floor and the aggregate at room temperature until you are ready to use it.

What is the shelf-life of Flash Floor?

When Flash Floor is stored properly in a dry, climate-controlled environment with an average temperature of 70° F, it is shelf stable for a minimum of 6 months.

Is Flash Floor a stocked item or is there a lead time?

Yes, Flash Floor is a stocked item and we ship all orders within 24 - 48 hours.

Where can I get a copy of Flash Floor's Material Safety Data Sheet (MSDS)?

You can view and/or download a copy of Flash Floor's MSDS here.

Can I use Flash Floor outdoors?

Yes, but Flash Floor is affected by sunlight; therefore after you are finished with the repair it should be painted with a concrete paint or coating to protect it.

What happens to a Flash Floor repair when it is exposed to regular sunlight?

Two things can happen to a Flash Floor repair when it is exposed to regular sunlight. First, the repair will turn a golden yellow. Second, the repair can lose a small amount of its strength.
