Calcium chloride moisture test results

[Tonythefish]

Used 6 tests kits spread out over 2800 square foot slab . Slab is 6” poured in July . Location is Florida.
From what I can tell these are elevated moister reading for any type of floor covering like Epoxy/sealers ? Test was done over 63 hrs
I just did a 18”x18” clear plastic test for 24hrs and had no moisture seen

The readings you are showing are very high for an epoxy unless you use a moisture blocking epoxy first which for best practices the floor should be shot blasted first for adhesion.

We have recommended this product which seems to work very well holding back moisture and is inexpensive. We would suggest trying it and then retaking the readings and you may be just fine. https://www.vanhearron.com/product/deepseal/
