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:

Depending on the width and depth, 1 cartridge can repair up to 8-12 linear feet at an average width of 1/2 inch by an average depth of 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 1½ inches deep (96 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, sources like cracks or voids for Flash Floor to leak out of the repair, and so on.

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.
