• Zero VOC

When properly prepared, suitable substrates include:

• Concrete
• Cement backerboards

• Quarry tile
• Epoxy terrazzo
• Exterior grade plywood, C-C (plugged) or better
• Exterior grade lauan plywood—Type I Trademarked Exterior Grade, OVL, CC, BB.OVL face grades only
• Vinyl composition tile (VCT), embossed resilient floor coverings—must be bonded well to an approved substrate and be single layer.*
• Adhesive residue (except tacky or pressure-sensitive adhesive)*
• Gypsum substrates** - minimum tensile bond strength 72 psi (0.5 MPa)

*Prime substrate with TEC® Multipurpose Primer or mix with TEC® Patch Additive.
**Requires priming with TEC® Multipurpose Primer.

Coverages shown are approximate. Actual coverages may vary according to substrate conditions and thickness of applications.

Before application, make sure that all surfaces are structurally sound, dry and free from any oil, grease, dust, loose or peeling paint, sealers, floor finishes, curing compounds or any contaminant that would inhibit or prevent a solid bond. Concrete and cementitious substrates must be fully cured and free of any hydrostatic pressure. TEC® Feather Edge can be installed over green concrete up to 100% RH. This product is not a moisture vapor barrier. If substrate moisture content exceeds the maximum allowed by the flooring manufacturer, then moisture mitigation must be applied prior to application of Feather Edge. To reduce moisture vapor emissions to an acceptable level, use TEC® LiquiDamTM Penetrating Moisture Vapor Barrier or LiquiDam EZTM Moisture Vapor Barrier (see product data sheets for details). Any protrusions on the surface must be removed by sanding, scraping or chipping. Vacuum all dust before application. DO NOT cover existing building expansion or control joints.

• For interior use only.
• Not for use in conditions with hydrostatic pressure or excessive moisture.
• Do not use as a wear surface or to patch over sealed concrete, tempered hardboard, particle board, strip wood flooring, over heavily cushioned flooring or perimeter bonded flooring.
• Do not apply when the temperature is below 50°F (10°C).

Mixing

Mix only as much TEC® Feather Edge that can be used in a 15-20 minute time period. USE IMMEDIATELY after mixing. Add the bag of TEC® Feather Edge slowly into 21/4-21⁄2 quarts (2.13-2.37 L) of clean, cool water while mixing at a low speed (not exceeding 300 rpm to prevent entraining air). For smaller amounts, use a mixing ratio of 2 parts powder to 1 part water. Mix thoroughly to a smooth, lump free consistency. Do not overwater.

TEC® Patch Additive is required for use as an embossing leveler. When TEC® Patch Additive is needed, slowly add the entire bag of TEC® Feather Edge into 21⁄2 quarts (2.37 L) of TEC® Patch Additive mixing at a low speed (not exceeding 300 rpm to prevent entraining air). Mix thoroughly to a smooth, lump-free consistency.

Application

After mixing, immediately work TEC® Feather Edge into the void to be filled with a flat, steel trowel and finish to a level surface with the required smoothness. This product has a 15 to 20 minute working time depending on the temperature. Working time is shortened with high temperatures. Any repairs greater than 1⁄2" (12 mm) in thickness will require two applications. Allow the first application to set before applying the second. Do not exceed a total thickness of 1" (25 mm) of TEC® Feather Edge. Do not overwork the product.

Curing

TEC® Feather Edge is ultra-fast drying and can tolerate foot traffic and installation of most floor covering materials in as little as 15-20 minutes and up to 60 minutes, depending on thickness and substrate. TEC® Feather Edge should be protected in hot, dry or windy conditions to avoid rapid water loss.

Clean-up

While material is still fresh, wash hands, tools and equipment with warm, soapy water.

*Flooring installation after application is dependent on thickness, drying conditions, and type of flooring.
