3. DESCRIPTION
Ready-to-use, flexible, mold and mildew resistant waterproofing crack isolation
membrane for interior and exterior applications. Forms a smooth, monolithic,
watertight surface over walls, floors and ceilings. HydraFlex™ Membrane stops
in-plane cracks up to
1
/
8
" (3 mm) or up to
1
⁄4 " (6 mm)* wide at the subfloor from
telegraphing through to ceramic and stone tile. For residential to extra heavy
commercial applications.

Suitable Substrates
When properly prepared, suitable substrates include:
• Concrete (minimum 3 days old), cured mortar beds and masonry (interior or
exterior)
• Gypsum wallboard (interior), cementitious backer units (CBU or cement board.
Interior or exterior)
• APA Grade Trademarked Exposure 1 Plywood [CDX or better; two layers, 1
1
⁄8 "
(28 mm) total minimum thickness, interior floors only]
• Gypsum underlayment (minimum compressive strength 2000 psi)
• Existing ceramic tile, VCT or non-cushioned sheetgoods provided they are single
layer only and well bonded to a substrate approved for tile (interior)
• Adhesive residue (except tacky or pressure-sensitive adhesive, interior only)
• Cold rolled steel
Substrate Preparation
Application surfaces must be free from oil, grease, dust, paint, concrete sealers,
floor finishes or curing compounds. New concrete shall be finished with a steel
trowel, have a fine broom finish, and must cure a minimum of 3 days. For high
moisture vapor emission concrete applications, the maximum acceptable moisture
vapor emission rate is 12 pounds per 1000 square feet (5.4 kg per 92.9 m
2
)
per 24 hours when evaluated by ASTM F1869 or 90% relative humidity per
ASTM F2170. Where required, existing concrete surfaces shall be prepared by
mechanical method such as scarifying, grinding, sand blasting or shot blasting.
Surface protrusions and tile glazes will be removed by sanding, scraping or
scarifying. After preparation, remove all dust by vacuuming. Clean concrete floor
from dust with a wet sponge and let the floor dry completely before membrane
application. Note: Vinyl asbestos tile or any substrate containing asbestos must
not be sanded, scored or scarified because of the potential health hazard of
breathing dust. Any substrate containing asbestos must be handled in accordance
with existing EPA regulations. Contact your local EPA office. Patch and fill holes
and voids with an appropriate TEC
®
surface preparation product. Treat existing
building construction, contraction (control), expansion or isolation joints as
required in the following installation instructions. Provide movement joints in the
tile where specified.
Storage
Store in cool, dry location. Do not store open containers, nor leave containers
exposed to sunlight. Product must be kept at temperatures of 40°-90°F (4°-32°C).
Keep from freezing.
Shelf Life
Maximum of 1 year from date of manufacture in unopened package.
Limitations
• Not for use as a wear surface.
• Do not apply over wet areas.
• Do not use over dimensionally unstable substrates such as particle board,
pressboard, lauan plywood, waferboard, tempered hardboard (e.g. Masonite)
or fiberglass.
• Do not use in areas subject to hydrostatic pressure from beneath the membrane.
• For exterior wall applications, refer to local building codes for moisture vapor
transmission requirements.
