3. DESCRIPTION
TEC
®
Fast-Set Deep Patch is a cement-based underlayment designed specifically
for deep fills, ramping, and leveling concrete and plywood subfloors (dry areas
only) from featheredge up to 1
1
⁄2 " (38 mm) in a single application, up to 5" (12
cm) with proper aggregate. Can be applied with steel trowel, float and/or screed
to produce a smooth, level surface. TEC
®
Fast-Set Deep Patch cures to a walkable
surface in approximately 60 minutes.
Key Features and Benefits
• Calcium aluminate technology for rapid strength development
• Interior/exterior use (use TEC
®
Patch Additive for exterior use)
• Featheredge to 1
1
⁄2 " (38 mm) in a single application, up to 5" (12 cm) with
proper aggregate
• Fast-set — allows for quick installation
• High bond and compressive strengths
• Provides smooth surface ready to accept flooring
• Self-drying formula

Suitable Substrates
When properly prepared, suitable substrates include:
• Concrete
• Burnished concrete*
• Epoxy terrazzo*
• Cement terrazzo
• Epoxy coatings*
• Ceramic tile (including porcelain and quarry tile)*
• Exterior grade plywood, APA grade trademarked exterior plywood, C-C
(plugged) or better (no additive needed)
• Gypsum Substrates* - minimum tensile bond strength 72 psi (0.5 MPa)
*Requires priming with TEC
®
Multipurpose Primer
Substrate Preparation
All surfaces must be structurally sound, dry and free from oil, grease, dust, loose
or peeling paint, sealers, floor finishes, curing compounds or any contaminant
that would prevent a good bond. Concrete and cementitious substrates must be
fully cured and free of any hydrostatic pressure or excessive moisture. All surface
protrusions must be removed by sanding, scraping or chipping. Remove all dust
by vacuuming. For surfaces that require priming, use TEC
®
Multipurpose Primer
per label instructions. Not recommended for use over expansion or control joints.
Notes: 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.
Storage
Store in a cool, dry area. Do not store open containers.
Shelf Life
Maximum shelf life is from date of manufacture in unopened package.
Plastic bag: 3 years Moisture-resistant bag: 1 year
Limitations
• Do not apply when the temperature is at or expected to be below 50°F (10°C).
• Not for use in conditions of hydrostatic pressure or excessive moisture [when is
RH greater than 95% or 15 lb. per 1000 ft
2
(0.07 kg/m
2
) per 24 hours].
• Not recommended for use as a wear surface.
• Not for use over sealed concrete, resilient flooring, strip wood flooring,
tempered hardboard, particle board or lauan plywood.
