Calcium Chloride Concrete Floor Moisture & Alkalinity (pH) Test Kits
Calcium Chloride Tests - also called the dome test - are designed to measure the moisture vapor emission rate of concrete subfloors using anhydrous calcium chloride.
Designed and developed by contractors, Vapor Gauge Test Kits will give a clear and precise reading of how much moisture is released up through a concrete slab into the floor covering. The testing kits can determine whether or not there is a moisture problem and will allow the contractor/installer to fix this before it becomes a flooring issue.
In addition, a pH test kit is included to measure the concrete alkalinity at the surface. Both test kits meet and conform to the American Society for Testing and Materials (ASTM) F1869-04 and F1907-04.
The red dome is designed to increase visibility thus promoting safety at any job site. Its visibility also helps prevent damage to the dome and dish that could result in re-testing. Always refer to the floor covering, coating and adhesive manufacturer's specifications regarding maximum limits for concrete moisture vapor emission and alkalinity.

Verify that the building’s environmental controls are operational. The building temperature and humidity should be representative of what it would be during normal use. The temperature should be between 65 F to 85 F and the relative humidity between 40% and 60 % for minimum of 48 hours prior to conducting tests.
On the first day preparation will take place. On the following day the tests should be set and then later retrieved in 60 to 72 hours. The tests need to remain undisturbed for a minimum of 60 hours and a maximum of 72 hours.
Place tests throughout the area with some in the middle of the building, at the perimeter, over cracks and joints and especially in area of potential moisture. The tests should be performed at a rate of three tests for the first 1,000 square feet and one additional test for each 1,000 square feet.
Remove foreign substances such as adhesives, curing compounds, sealers and floor covering materials. Before removing foreign substances and/or preparing the test site verify that the existing materials do not contain asbestos and/or lead. Prepare a 20” x 20” test site by mechanical means and leave exposed a minimum of 24 hours prior to setting the tests.
Remove calcium chloride from the packing and weigh with a gram scale capable of measuring 0.1 gram. Do not remove tape prior to weighing. To assure more accurate results always weigh tests on site and just prior to setting. Record the weight and time on the dish label. Remove tape from calcium chloride container and adhere to the outside of dome to check for leaks.
Remove dish lid and place underneath the bottom piece. Be careful not to spill any calcium chloride. Place open calcium chloride container on the center of the test site, remove gasket cover and adhere dome to the concrete surface. Press firmly on flange until gasket reaches the outer part of the flange. Press on the center of the dome to check for leaks.
Retrieving Calcium Chloride Container
Cut dome top with a box knife in a u-shape large enough to remove the calcium chloride container without spilling and calcium chloride. Replace dish lid cover, re-adhere tape and re-weigh. Record the weight and time on the dish label.
Perform one alkalinity test for every calcium chloride test. Place a quarter-sized amount of the pre-packaged test solution on concrete surface. Let solution stand for sixty seconds and then place pH paper into water and let stand for five seconds. Remove pH paper and immediately compare to color chart. Record pH test results on the corresponding calcium chloride dish
