5. INSTALLATION INSTRUCTIONS
INSTALLATION INSTRUCTIONS AS WATERPROOFING MEMBRANE
Mixing
Substrate and material must be maintained at 50°-90°F (10-32°C) for 24 hours
before, during and after application. Into a clean, five gallon (18.92 L) pail, pour
only
2
⁄
3
the contents of Part A liquid. Add all Part B dry powder. Avoid breathing
dust and contact with eyes and skin. Mix thoroughly until lump free (approximately
3 minutes) using low speed mixer to prevent entraining air. Mixture should be
thick and pasty. Blend in remaining Part A liquid. Allow to stand for 5 minutes.
Remix to achieve a smooth, loose, final working consistency. Never add water to
this product.
Membrane Application
To achieve waterproofing properties, a continuous membrane of at least 45 mils
is required over the entire surface. This can be accomplished using the following
technique: 1) Using the flat side of a
3
⁄
16
" (4.7 mm) V-notch trowel, “key in” a thin
coat of membrane. 2) Immediately afterwards, apply additional material using
the notched side of the trowel held at approximately a 45˚ angle to the substrate.
3) Again using the flat side of the trowel, flatten the ridges to form a smooth,
continuous layer approximately 45-50 mils [
3
⁄
64
" (1.14-1.27 mm)] thick. Make sure
there are no voids, bubbles or breaks in the membrane after cured. If any holes
appear in the cured membrane, apply a second coat to fill the imperfections.
Periodically check membrane with a wet-film gauge to ensure a continuous
45-50 mil [
3
⁄
64
" (1.14-1.27 mm)] thick film is being achieved. Average pot life is
2 to 4 hours.
Allow membrane to cure and install tile using a suitable TEC
®
brand latex-modified
thin set mortar or TEC
®
AccuColor EFX
®
Epoxy Grout and Mortar (epoxy for interior only).
Note: If water testing is desired/required prior to tile installation, allow membrane
to cure at least 72 hours.
Mesh Application (Flashing) — required for all waterproofing
applications
Construction Details: Flashing with TEC
®
Waterproofing Mesh (Part C) is
required at all substrate joints; inside corners; outside corners; anywhere vertical
surfaces meet horizontal surfaces such as curbs, bench seats, columns, etc.; or
anywhere dissimilar materials meet.
To accomplish flashing: First, use Triple Flex™ membrane compound to pre-coat
the substrate intersections 4" (100 mm) on either side. Second, fully embed
Part C mesh 3" (76 mm) in both directions into the pre-coated areas. Third, trowel
on additional Triple Flex™ membrane to completely cover and saturate the mesh.
The minimum thickness of the flashing shall be
3
⁄
32
" (2.4 mm). Allow the flashing
to dry (approximately 20 minutes) before full application of waterproof membrane.
Note: Where two pieces of mesh meet, be sure to overlap the mesh 3" (76 mm)
at the ends.
