Vapor Score Calcium Chloride Test Kits

Description

• This method has and is the industry standard. Calcium Chloride Test allow you to achieve a quantitative figure which will coincide with floor manufactures requirements.Please note: The measurement obtained performing a Calcium Chloride only reflects the current condition of the concrete.  Results will reflect a figure of weight in pounds of water evaporations giving off over 1000 ft2 over a 24hr period. The test must be done when the building is at the same temperature and humidity.
• Building Condition’s as perASTM F1869 allows for test conditions to between 65°F and 75°F and 40% and 60% relative humidity. These requirements need to be sustained for 48 hours proceeding to and during the test.
• The F 1869 method calls for cleaning a 20-inch-by-20-inch square at each test site to be sure you are testing bare concrete. This will remove curing compounds, sealers or old adhesive residue. The people who do testing for a living always grind the surface so the slab is completely clean. Failure to clean the slab may result in a false low reading.
• ASTM F 1869 calls for a 24-hour waiting period after cleaning before the test kit is placed so surface moisture that was trapped beneath whatever coating was there can evaporate. Failure to wait 24 hours may result in a false high reading.
