Suitable Interior Substrates
When properly prepared, suitable substrates include:
• Concrete
• Marble and terrazzo
• Metal
• Plywood - APA standard underlayment grade or better
• Multiply Underlayment
• Fiber-cement underlayment
• Portland cement based underlayment
• Well bonded, smooth, wax-free, existing single layer non-cushioned resilient
flooring.
• Radiant heated subfloors [surface temperature does not exceed 85°F (29°C)]
Substrate Preparation
Subfloor should be structurally sound, clean, dry and level. Remove all grease,
sealers, curing compounds, loose paint, dirt, etc. Nail down any loose edges or
areas of subfloor and sand smooth all raised edges. Fill cracks or depressions
in floor with a suitable TEC patching compound. Sand smooth and vacuum to
remove dust. Over hardwood floors or wood parquet, the installation of plywood
or fiber-cement underlayment is required. Plywood should be installed according
to American Plywood Association guidelines. Plywood subfloor surfaces should be
well nailed at all edges and through center.
All concrete substrates must be tested for moisture and pH prior to flooring
installation. Install flooring with TEC Releasable Pressure-Sensitive Adhesive over
concrete with a moisture vapor emission rate up to 10 lbs. per 1,000 sq. ft. (4.54
kg/93 m²) per 24 hours when tested in accordance with ASTM F1869 or up to
90% RH when tested in accordance with ASTM F2170. For concrete with greater
moisture levels, treat the concrete with TEC LiquiDam
™
Penetrating Moisture
Vapor Barrier. See Product's Data Sheet for details. Test for pH in accordance with
ASTM F710. Range of 7-9 is required.
Storage
Store in cool, dry location. Do not store open containers.
Shelf Life
Maximum of 18 months from date of manufacture in unopened container.
Limitations
• Do not use where hydrostatic pressure, excessive moisture or alkali is present.
• New concrete should be allowed to cure a minimum of 60-90 days prior to
installation.
• Do not use when temperature is below 60°F (15°C).
• Not recommended for installation over cushion-backed or unprepared
embossed sheetgoods.
• Freeze/thaw stable to 10°F (-12°C) for a minimum of 5 cycles. If frozen, slowly
bring to room temperature and stir before using.
