SEALTIGHT®
MEADOW-PATCH T1
ONE - COMPONENT, POLYMER MODIFIED, THIN REPAIR PATCH
MORTAR
DESCRIPTION
SEALTIGHT MEADOW-PATCH T1 is a one-component,
polymer-modified, cementitious resurfacing/repair mortar designed for
horizontal, vertical and overhead applications. This all-purpose mortar is
designed for patches, toppings and repairs from 1" thickness to
featheredge.
USES
MEADOW-PATCH T1 is easy to mix and apply;
versatile and produces repaired surfaces suitable for rubber-wheeled traffic.
For overhead or vertical use; MEADOW-PATCH T1 is an ideal choice for smoothing
rough surfaces, repairing honeycombs and dressing up bugholes. When mixed, this
creamy consistency provides an excellent skim coating for swimming pools,
concrete walls, balconies, etc. Because of its excellent bond and freeze-thaw
resistance, MEADOW-PATCH T1 may be used for interior and/or exterior; below,
above or on grade.
FEATURES / BENEFITS
 | Polymer Modified – Enhanced bond
| Low permeability – Protects embedded reinforcing
steel
| Enhanced flexuals and tensile properties
| Breathable – Will not act as a vapor barrier
| Excellent freeze-thaw characteristics – Long term
stability
| Creamy consistency – Easily finished |

PACKAGING AND STORAGE
MEADOW-PATCH T1 is available in 50 lb. (22.7kg)
bags. When stored on pallets in a dry, cool area, it has a shelf life of 12
months.
COLORS AND YIELD
Cement gray. MEADOW-PATCH T1 covers approximately
55 ft.² @ 1/8 in. (5m.² @ 3mm).
Yield per 50 lb. bag is 0.45 ft.³ (0.013m³)
LIMITATIONS
Do not apply MEADOW-PATCH T1 when the temperature
is expected to be below 45ºF (7ºC) within 48 hours or when rain is imminent.
Maximum application thickness must not exceed 1"
(25.4mm) neat. Avoid steel-wheeled traffic in thin applications. Thin
applications subject to point loading should also be avoided. Protect thin
applications from rapid water loss.
SURFACE PREPARATION
Mechanically abrade existing substrate to remove
all unsound concrete, but do not use excessive force which may cause
micro-fracturing. Prepare surface in accordance with ICRI Technical Guide No.
03730. Substrate must be structurally sound and free of grease, oil, dirt or any
other contaminants that can adversely affect the bond. Prepared surface must be
dust-free and have sufficient profile to ensure adequate mechanical lock.
Substrate must be saturated, surface dry (SSD) and free of standing water.
For maximum bond, prime (SSD) substrate with slurry coat
(two parts powder to one part SEALTIGHT ACRY-LOK). Allow slurry coat to become
tacky prior to application of MEADOW-PATCH T1. Do not allow slurry coat to
become tack free.
MIXING
Using a mortar type mixer, add 3.0 quarts (2.8L)
of clean water per 50 lb. (22.7kg) of MEADOW-PATCH T1. Slowly add powder and mix
to desired consistency, using up to 0.5 (0.47L) additional quarts of clean
water, as needed. Mix for 3 minutes, or until lump-free consistency is obtained.
Do not over mix. For small repairs, mix in a clean vessel using a variable-speed
drill with a paddle mixer at 400-600 rpm. Mix only complete bags. Do not mix
more material than can be placed and finished in 30 minutes at 77ºF (25ºC).
PLACEMENT
Apply MEADOW-PATCH T1 into the repair zone
substrate by compacting the material well against the properly prepared
substrate. Finish surface with wood or sponge float. Never retemper.
CURING
The use of SEALTIGHT EVAPRE may proceed
immediately after screeding and / or between finishing operations. MEADOW-PATCH
T1 must be cured in accordance with ACI 308 utilizing a suitable curing compound
such as SEALTIGHT 1100 Series, SEALTIGHT 1600 Series or VOCOMP-25. Protect from
rapid early water loss.
