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 end, 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:
1 cartridge can repair up to 10 linear feet at 1/2 inch wide by 1/2 inch deep.
For voids, spalls, holes, etc.:
1 cartridge can repair a hole that is 8 inches long x 8 inches wide x 2 inches deep (128 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.
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 just 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, minimal smell, etc. You can read more Information on Flash Floor vs epoxy here.
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. One, it will extend Flash Floor's volume or the amount you can repair by up to 200%. Two, it balances the strength difference or PSI between Flash Floor and the concrete. And three, it makes for a stronger repair.

Yes, just make sure the sand is 100% dry. We recommend a medium grain size sand-blasting sand.
