Floor Leveling

Floor Leveling before Floor Epoxy

When doing a slurry to level out an uneven floor it’s critical that the preparation is done properly. It doesn’t matter if you are going to apply an epoxy floor coating over it, put down some type of flooring or just leave it plain. The concrete must be profiled properly so that the slurry will bond to it. We recommend a shot blasting. It’s cheaper than grinding and it leaves a rougher surface.

Also use a good quality product such as Aedex-15 or CMP. These are commercial grade products that will last you a lot longer than the bargain stuff you can buy at your local Home Improvement store.

If you are applying an epoxy coating always check with the manufacturer on the wait time after curing. The cure time before you can apply any coating varies greatly between products. Also make sure the product you use is rated for the thickness you need to float the slurry at and that it can handle the intended traffic load at that thickness.

Most times the slurry is applied with a Gage rake which is simply an adjustable flat blade on rollers. You set the blade for the desired thickness and you roll the rake over the slurry. It spreads the slurry out at the desired thickness.

Done right slurries can save a floor that is in really bad shape, they are not just for leveling. But done wrong and you’ll end up like this:
