Norge Moisture Test Kit Single Pack
This test kit complies with and/or exceeds the ASTM F-1869 standard test method for measuring the moisture vapor emission rate of a concrete sub-floor using anhydrous calcium chloride.
Moisture testing ensures that you are installing over dry substrates and when it's safe to begin the installation.
Before beginning any installation over cement, test for moisture.
1. Cement must be a min of 90 days old
2. Building must be completed with window and doors installed and have the Heating, Ventilation, Air-conditioning (HVAC) fully operational
3. Three (3) Calcium Chloride tests are needed for the first 1,000 square feet. Add (1) additional test for each 1,000 square feet thereafter
4. Products such as adhesives and underlayments can have moisture limits, therefore compare testing results with the manufacturer's written instructions
Before beginning any direct glue installation over cement, test for excessive alkali.
Alkali is present in all cement. pH liquid test identifies the amount of alkali on the surface as excessive amounts can interfere with proper adhesive bonding.
Follow the directions supplied in the Testing Kit.

A little care needs to be taken. The samples are small and the measures are precise. Watch your time. I missed the first tests by 6 hours ... no results. The lab was quick to deliver my results, so now I have good confidence in my installation. Cheaper than a meter for my one time DIY floor installation.
We used this product to find out if we need extra underlayment (vapor barrier) under the underlayment (blue hawk=quite walk) for the concret. It helps us make the decision.
