Before an epoxy coating is applied to the floor jon don highly recommends considering the following.
Leveling concrete floor before epoxy.
All concrete contains moisture and if the moisture level is too high it may cause the leveling compound to degrade over time.
Spray or pour the mixture on the floor to etch the surface then go over the floor with your power floor scrubber again.
You run the risk of consuming a lot of product with absolutely nothing to show for.
New slabs of concrete should be allowed to fully cure for 30 60 days before a coating is applied if a sealer was previously used on the concrete if water beads up on the surface do not use epoxy.
Note the caps and bold.
Other solutions could be grinding the substrate or using epoxy grout to fill the substrate unevenness.
Preparing to use self leveling concrete.
Before you install your new floor there s an essential consideration you need to address and that s moisture in the existing concrete floor.
If you need to even out the surface before you apply the epoxy you could look into using self leveling cementitious compound.
This will not happen.
A common misconception is that by applying a high build epoxy coating like a self leveling on uneven concrete the floor will magically become smooth and level.
