5. INSTALLATION
Applications Instructions
PROFLEX® elastomeric membranes, when properly installed in accordance with the following installation guidelines, will provide
years of protection for finish flooring installations. In addition to these instructions, installers shall also refer to the most current
edition of the following publications: American National Standards Institute (ANSI) publications. Tile Council of North America
(TCNA) Handbook for Ceramic Tile Installations The Marble Institute of America (MIA) Dimension Stone Design Manual.
Manufacturer's instructions of selected setting materials, substrates, sub-floors, or other manufacturers being used in the total, or
any part of, an installed flooring system with PROFLEX® Consult your selected manufacturer of these above mentioned
components to ensure selected products are compatible with PROFLEX® elastomeric membranes.
Exclusions
PROFLEX® should not be installed without contacting technical support for including, but not limited to, the following conditions:
Expansion or structural design joints in concrete slabs, Out of plane, or structural movement cracks. Horizontal cracks that exceed
⅜” (10mm) Areas where moisture vapor or hydrostatic pressure exceeds 5#-1000sqft-24hrs, as tested using a Calcium Chloride
(CaCl) test. Substrates installed not in compliance with industry standards. Substrates that have not been approved by PROFLEX®
in this document, or by written authorization from a PROFLEX® representative.
Surface Preparation of Selected Substrates
Concrete Substrates shall be in place a minimum of 28 days. Concrete shall be installed in compliance with industry standards,
and concrete manufacturer’s instructions. The surface shall have a smooth finish and be free from voids, sharp protrusions, and
loose aggregate. Substrate temperatures should be between 40oF and 90oF Concrete shall be structurally sound, dry, clean, and
free of dirt, oils, grease, loose peeling paint, concrete sealers or curing compounds, cement laitance, and other similar bond
inhibiting materials. Rough or uneven surfaces should be made smooth with a Latex Portland cement underlayment to provide a
wood float or better finish. Do not level with asphalt based products. Concrete should be tested for both moisture vapor transmission
and hydrostatic pressure, by use of a Calcium-Chloride (CaCl) test. Consult technical support if test readings indicate a reading
greater than 5 # per 1000 sqft-24hours. Existing joint openings larger than 3/16” must be prepared and filled with an approved
caulking or sealant prior to the application of PROFLEX®.
Patching, Self Leveling Compounds, Lightweight Gypsum Concrete (Gyp-Crete®) shall cured to the minimum manufactures
requirement for moisture sensitive installations. The surface shall have a smooth finish and be free from voids, sharp protrusions,
and loose aggregate. Substrate temperatures should be between 40oF and 90oF and shall be structurally sound, dry, clean, and
free of dirt, oils, grease, loose peeling paint, sealers or curing compounds.
