Easy and fast concrete moisture testing for the installer to perform at the time of the flooring installation. (Chapters at the end of the description).
Even if pre-installation moisture testing has been performed, conditions can change that will affect your installation of flooring or coatings. By implementing this easy Installation Quick Check - IQC, you can prevent failures before they happen.
Make sure the site is in in-service condition.
Step 1) Ambient Conditions - Dew Point
Step 2) Surface Temperature of the slab
Note: make sure that the temperature of the slab is at least 10°F (5°C) above the dew point.
Step 3) % Moisture Content (MC) of the surface of the slab - use the Tramex Concrete Moisture Encounter 5 - CME5, or the Tramex Moisture Encounter X5 - CMEX5, to get quantitative percentage moisture content readings.
How to test:
- Make sure you have a clean area, abraid the surface as needed to get any residue off the surface of the slab, and avoid any painting or drywall mud.
- Press the meter on the surface and get a reading. And each place you take a reading, you want to "go around the horn": take a reading at 12, 3, 6, and 9 o'clock (rotating the meter 90°) and take note of the higher number.
Industry professionals generally recommend the number of 4% MC for floor coverings and 3.5% MC for concrete coatings.
When taking surface readings perform at least 8 tests for the first 1,000 ft² (100 m²) and at least 5 for each additional 1,000 ft² (100 m²) - per ASTM F2659 section 10.6.
Industry standards say if no pre-installation moisture testing was performed and a flooring or coating encounters a failure due to moisture after the install, the responsibility falls on the installer. Tramex recommends the Installation Quick Check - IQC, as a way to protect yourself against any moisture-related claims after the installation.
There are two kits to perform the Installation Quick Check:
- IQC Plus Kit: Digital CMEX5 and Infrared Thermometer - tramexmeters.c...
- IQC Kit: Analog CME5 and Infrared Dew Point Scan Thermometer - tramexmeters.c...
Both come in a convenient carry case and are equipped with Bluetooth to connect to the Tramex Meters App.
