Examine substrates, areas and conditions,with Applicator present, for compliance with requirements <br /> for maximum moisture content, installation tolerances and other conditions affecting flooring <br /> performance. <br /> 1. Verify that substrates and conditions are satisfactory for flooring installation and comply with <br /> requirements specified. <br /> 3.2 PREPARATION <br /> A. General <br /> 1. New and existing concrete surfaces shall be free of oil, grease, curing compounds, loose particles, <br /> moss, <br /> algae growth, laitance, friable matter,dirt, and bituminous products. <br /> 2. Moisture Testing: Perform tests recommended by manufacturer and as follows. <br /> a. Perform anhydrous calcium chloride test ASTM F 1869-98.Application will proceed only <br /> when the vapor/moisture emission rates from the slab is less than and not higher than 20 <br /> lbs/1,000 sf/24 hrs. <br /> b. Perform relative humidity test using is situ probes,ASTM F 2170. Proceed with installation <br /> only after substrates have a maximum 99%relative humidity level measurement. <br /> c. If the vapor drive exceeds 99%relative humidity or 201bs/1,000 sf/24 hrs then the Owner <br /> and/or Engineer shall be notified and advised of additional cost for the possible installation of <br /> a vapor mitigation system that has been approved by the manufacturer or other means to lower <br /> the value to the acceptable limit. <br /> 3. Mechanical surface preparation <br /> a. Shot blast all surfaces to receive flooring system with a mobile steel shot, dust recycling <br /> machine(Blastrac or equal). All surface and embedded accumulations of paint,toppings <br /> hardened concrete layers, laitance,power trowel finishes and other similar surface <br /> characteristics shall be completely removed leaving a bare concrete surface having a <br /> minimum profile of CSP 4-5 as described by the International Concrete Repair Institute. <br />
