Calcium Chloride Concrete Moisture & Alkalinity Test KitAuthorized Distributer of Vapor Score products Calcium Chloride Concrete Moisture & Alkalinity test kits
Authorized Distributer of VaporGuage products Calcium Chloride Concrete Moisture & Alkalinity test kits
Test your moisture vapor transmission rate before coating concrete slabs with :
Epoxies, Paints, Polyaspartics, Glues, Standard floor coverings to make sure you do not have a future floor coating failure. Check with the manufaturer as to what the acceptable limit is for vapor transission rate for the desired product.

This anhydrous calcium chloride vapor test kit was developed over 40 years ago to quantify the volume of water vapor radiationg from a concrete slab surface over time. This test is directly specified by the vast majority of the Floor Covering Industry as the primary measure of moisture acceptability for floor covering installation.

Use this test to model the amount of moisture that emits from 1,000 square feet of slab surface in 24 hours. The result is expressed in pounds which is the equivalent weight of water, emitted as vapor, over 1,000 square feet in 24 hours. Use this result to compare to the manufacturere's specifications for floor covering or coating tolerances. Always reference a copy of the manufacturer's specifications when reporting results using this test. Most manufacturers select the industry standard of 3lbs vapor pressure per 1000sq ft as a maximum for coating or covering concrete before treatments are required to reduce the vapor level.

This test requires the use of a gram-weight scale with a graduation of 1/10th (0.1) gram. The calcium chloride container is weighed before and after exposure to the concrete slab. It is highly recommended that the test be weighed prior to, and directly after exposure using the same scale to ensure uniformity and accuracy of test results

Test Instructions

Concrete Moisture & Alkalinity Testing Instructions:
 
Survey Job Site Conditions
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  or 18° C to 25° C and the relative humidity between 40% and 60% for minimum of 48 hours prior to conducting tests.
Schedule Accordingly
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.
 
Test Location & Frequency
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.
Test Site Preparation
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 (diamond cup wheel on grinder if possible) and leave exposed a minimum of 24 hours prior to setting the tests.
Weigh Calcium Chloride Container
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.
Placing Dome Cover
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 Alkalinity Tests  (a pH of 7 is neutral )
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. Chart included in kit. Record pH test results on the corresponding calcium chloride dish. High pH refers to High alkaline soil salts penetrating trough the slab. Check with manufactures specifications if you are treating or coating the concrete that it is compatible with high pH above 9.

 

Test your concrete slab before coatings or painting with a Moisture Emission Kit, Anhydrous Calcium Chloride vapor test kit.
Prevent concrete coating failures in advance and treat concrete before coating.
