These products (garage floor epoxies) are not intended to hold back water pressure ... known as hydrostatic pressure.


In fact, none of our hydrostatic products are designed for walking surfaces.


You best bet would be controlling the flow of water outside your building:


1) Gutters and downspouts that direct water away from the foundation;

2) French drain that collects rain water from the yard and prevents it from getting next to the foundation; and

3) Exterior foundation sealer ... digging out the earth next to the foundation and re-applying the sealer.



After you control the water outside the building, your prep for the interior floors include:


1) The citric acid etcher included in the 2-Part Epoxy kits; and

2) The Behr Cleaner Etcher in the one-gallon jug.

 A simple test for the presence of moisture under a slab is to tape a couple square foot piece of plastic, such as a piece of garbage bag, to the floor for 24 hours. If moisture is evident when it is pull, you might want to reconsider the epoxy. The companies that do such work will not proceed if such moisture is present, or at least not waurantee the job.


That being said, I doubt that you will find moisture present. Most newer construction would have a perimeter footing and several inches of gravel underneath with heavy plastic placed down before the cement is laid. Such construction would prevent moisture from coming up through the slab.
