Concrete: Apply only to clean, dry and sound concrete substrates that are free of all coatings, sealers, curing compounds, oils, greases, or any other contaminants

• New concrete should be cured a minimum of 28 days.
• Concrete that has been contaminated with chemicals or other foreign matter must be neutralized or removed.
• Remove any laitance or weak surface layers.
• Concrete should have a minimum surface tensile strength of at least 300 PSI per ASTM D-4541.
• Surface profile shall be CSP-3 to CSP-5 meeting ICRI (International Concrete Repair Institute) standard guideline #03732 for coating concrete, producing a profile equal to 60-grit sandpaper or coarser. Prepare surface by mechanical means to achieve this desired profile.
• Moisture vapor transmission should be 3 pounds or less per 1,000 square feet over a 24 hour time period, as confirmed through a calcium chloride test, as per ASTM E-1907. Quantitative relative humidity (RH) testing, ASTM F-2170, should confirm concrete RH results 75%.
• All surface irregularities, cracks, expansion joints and control joints should be properly addressed prior to application.
• Outgassing may occur due to the porosity of some concrete surfaces. To reduce the effect of outgassing, the primer and coating should be applied when the temperature of the concrete substrate is dropping. This usually occurs in the evening: however the concrete substrate temperature should be measured with a surface thermometer for verification. Double priming will greatly reduce the effectsof outgassing by additionally filling the pores in the concrete
