Pre-Installation Checklist
A successful installation requires proper preparation of the sub floor. Read and understand all applicable guidelines and technical data sheets before installation. Follow industry standards and flooring manufacturer's recommendations for sub floor moisture content, design, layout and application of flooring materials. All substrate constructions must meet the specific requirements of the floor covering to be installed.Installation Procedure - Primer Over Porous / Non-Porous Surfaces.
Sub Floor Examination - Prior to installation, the subfloor must be checked according to applicable installation guidelines. It must be solid and sound, clean, free of chaps and anti-adherents, as well as resistant to pressure and tension. Check for missing or compromised vapor barriers and hydrostatic pressure. Perform RH or CaCl moisture tests following ASTM standards. Moisture content in concrete sub floors must be below 3#/24hrs/1,000 sq. ft.using the Calcium Chloride Test or less than 75% RH using the in-situ test.
Sub Floor Preparation - The condition of the sub floor will determine which type of mechanical treatment is required (e.g. wire brushing, sanding, grinding or shot blasting). Dust, paint, curing compounds, sealers, residual adhesives or other surface pollutants MUST be removed by suitable means. Extent of sub floor preparation can only be determined at the site by the installer. Clean the surface with an industrial vacuum cleaner, tack or damp mop floor before application. Do not use sweeping compounds as most will contain oil or wax which will act as an anti-adherent and prevent primers, sealers, leveling compounds and/or adhesives from bonding to the concrete.
Application - Shake or stir before use and apply primer with appropriate applicator and dilution ratio. Make sure primer is spread evenly. Do not exceed the maximum coverage. (see coverage chart) Higher temperatures will speed up the drying time.
Installation Procedure - Primer Over Adhesive Residue and Existing Flooring.
Sub Floor Examination - Prior to installation, the subfloor must be checked according to applicable installation guidelines. It must be solid and sound, permanently dry, clean, free of chaps and anti-adherents, as well as resistant to pressure and tension. Moisture content of all floors must be measured before installation. Moisture content in concrete sub floors must be below 3#/24h/1,000 sq. ft. using the Calcium Chloride Test or below 75% RH using an in-situ probe. Existing cutback mastic must be permanently bonded to the sub floor. The floor must be inspected and tested for asbestos. If asbestos is found, it must be properly removed or abated before continuing installation. SP1 is not to be used as asbestos abatement.
Sub Floor Preparation - The condition of the sub floor will determine which type of mechanical treatment is required (e.g. wire brushing, sanding, grinding or shot blasting). Dust, paint, curing compounds, sealers, residual adhesives or other surface pollutants MUST be removed by suitable means. Extent of sub floor preparation can only be determined at the site by the installer. Clean the surface with an industrial vacuum cleaner, tack or damp mop floor before application. Do not use sweeping compounds as most will contain oil or wax which will act as an anti-adherent and prevent primers, sealers, leveling compounds and/or adhesives from bonding to the concrete.
Application - Shake or stir before use and apply primer undiluted with brush or foam roller. Avoid puddles as they prolong the drying period. Apply primer once and not too thick. On poorly absorbent sub floors the primer must be applied sparingly; do not leave a visible layer of primer on the floor. Once dried, the primer is transparent. Higher temperatures will speed up the drying process.
Installation Procedure - Sealer Porous Surfaces.
Sub Floor Examination - Prior to installation, the subfloor must be checked according to applicable installation guidelines. It must be solid and sound, clean, free of chaps and anti-adherents, as well as resistant to pressure and tension. Check for missing or compromised vapor barriers and hydrostatic pressure. Perform RH or CaCl moisture tests following ASTM standards. Results of 99% RH or 25# CaCl could indicate that there is a higher moisture content in the slab than what tests can measure and there might be hydrostatic pressure and/or a compromised or missing vapor barrier. Moisture content in concrete sub floors must be below 8#/24hrs/1,000 sq. ft. using the Calcium Chloride Test or less than 85% RH using the in-situ test.

Do not use sweeping compounds as most will contain oil or wax which will act as an anti-adherent and prevent primers, sealers, leveling compounds and/or adhesives from bonding to the concrete. Cracks and gaps must be treated prior to application of primers, sealers, leveling compounds and/or adhesives.
Application - Shake or stir before use and apply sealer undiluted with appropriate applicator. Make sure sealer is spread evenly. Do not exceed the maximum coverage. Higher temperatures will speed up the drying time. Sealer application for wet concrete slabs up to 8#/24hrs/1000SF and 85% RH apply using PROFLEX® Rake Trowel up 80 SF/gal (see coverage chart).
Treatment of Cracks and Gaps
There are several types of cracks and gaps that need to be treated differently.- Hairline or spider web cracks: They are typically less than 1/32” wide and only topical. They do not need to be treated prior to application of sealers.
- Stress cracks or relief cuts: They are over 1/32” up to 1/8” wide. They will need to be filled with an epoxy concrete crack filler.
- Relief cuts or non-moving voids: They are over 1/8” wide and may go all the way through to the bottom of the slab. A PROFLEX® Backer Rod will need to be inserted into the void to retain the crack filler. Fill the remaining void with an epoxy concrete crack filler.
- Dynamic or moving joints: They are intentional separations between two sections of concrete that allow for expansion and contraction. They will need to be honored throughout the entire installation. The usage of the facility and the amount of movement will determine the appropriate product and installation procedure.
