INSTALLATION INSTRUCTIONS – MOISTURE TESTING

It is required that a series of anhydrous calcium chloride tests be properly performed per ASTM F-1869 to determine vapor emission rates. To achieve the proper information and determine the scope of magnitude of vapor emission rates, it is imperative that the environmental systems (heating or air conditioning) be engaged along with all doors and windows being installed and closed for the duration of the test procedure. The project should be at the same temperature and humidity levels expected during normal use. If this is not possible then the environment should be at 65-86 degrees F with a relative humidity of 40-60%. Failure to properly acclimate the area will result in incorrect test results. Follow the ASTM specifications for preparation of the concrete and remove all existing materials such as paint, adhesives, curing compounds, densifiers, hardeners, sealers or any deleterious material. Weigh sealed dishes immediately prior to placing on the concrete and seal and weigh the tests immediately upon removal. Perform a pH test using a pH pencil for accurate results - do not use litmus paper. Properly document all results and procedures including environmental conditions, i.e.: room temperature, humidity, moisture vapor emission readings, test placements, etc for future reference.

INSTALLATION INSTRUCTIONS – APPLICATION

• Allow pH Blocker/Primer 100 to acclimate at room temperature for 24 hours prior to instal-lation. Do not allow the pH Blocker/Primer 100 to freeze. Even though the pH Blocker/Primer100 is a solvent free material, effective ventilation should be provided.
  
• The area MUST be acclimated to at least 60 degrees F and 40% relative humidity for at least 48 hours prior, during and following the installation procedure.
  
• The concrete must be free of dust, old adhesive, dirt, paint, wax, grease, oil, curing agents, densifiers, bond breakers or any other substances that could inhibit bonding. Use only mechan-ical methods to clean existing sub floor. Do not acid etch or use any other chemical to clean.
  
• Note: The concrete MUST BE porous in order to facilitate bonding with the pH Blocker/Primer 100. It is imperative that penetration into the concrete with the pH Blocker/Primer 100 is achieved. It is important to perform a bonding test using the pH Blocker/Primer 100. Begin by applying the pH Blocker/Primer 100 on a 2 ft by 2 ft area, using a 1/4” nap roller. If after appli-cation and curing of the pH Blocker/Primer 100, and allowing at least 5 hours to cure (com-pletely dry and non-tacky), it can be removed using the flat edge of a trowel, then the proper level of porosity has not been achieved.
  
• To ensure porosity, the concrete MUST BE porous for penetration of the Vapor control system. Steel troweled or concrete cured with curing compounds may need to be lightly bead blasted to ensure porosity. The steel bead shot size shall be a #230 to #280 mesh profile to obtain a satisfactory surface.
  Caution: More aggressive shot blasting may require a cementituous skim coat application prior to application of the vapor control system.
  
• Fill cracks, holes, and depressions using a quality Portland cementituous compound, preferably acrylic modified. Do not apply these materials, or skim coat AFTER the pH Blocker/Primer 100 has been applied.
  
• Using a 1/4” nap roller cover, evenly apply the pH Blocker/Primer 100 across the concrete. DO NOT ALLOW THE MATERIAL TO PUDDLE. Periodically check the coverage rate to ensure proper coverage and material usage. Allow the pH Blocker/Primer 100 to dry to a clear, non-tacky film (at least 5 hours).
  
• Coverage is approximately 400 to 500 square feet per gallon, over properly prepared concrete. Coverage may vary depending on the porosity and texturing of the concrete.

STORAGE AND HANDLING
pH Blocker/Primer 100 should be stored in a cool, dry space away from oxidizers or caustics. Even though this product is solvent free, proper ventilation should always be provided per the requirements of CRI 104. The shelf life is one (1) year from the date of production indicated on the unopened bucket.

CLEAN UP
pH Blocker/Primer 100 is slightly tacky until fully cured. Use soap and water to clean hands and tools when the pH Blocker/Primer 100 is still wet. When the pH Blocker/Primer 100 is fully cured, use a safety solvent to clean hands and tools and then rinse with soap and water.
