Project Profile

MEADOW-PATCH® T2

TWO - COMPONENT, POLYMER MODIFIED, THIN REPAIR PATCH MORTAR

DESCRIPTION
MEADOW-PATCH T2 is a two component, polymer-modified, cementitious repair mortar designed for horizontal, vertical and overhead applications. This all-purpose mortar is designed for patches, toppings and repairs from thicknesses of 1" to featheredge.

USES
MEADOW-PATCH T2 is easy to mix and apply, versatile and produces repaired surfaces suitable for rubber-wheeled traffic. For overhead or vertical use, MEADOW-PATCH T2 is an ideal choice for smoothing rough surfaces, repairing honeycombs and dressing up bugholes. When mixed, the product's 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 T2 may be used for interior and/or exterior; below, above or on grade. FOR INDUSTRIAL USE ONLY.

COLORS AND YIELD
Cement gray. MEADOW-PATCH T2 covers approximately 55 ft.² @ 1/8 in. (5m² @ 3mm). Yield per 50 lb. bag is 0.50 ft.³ (0.014m³)

PACKAGING AND STORAGE
MEADOW-PATCH T2 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.

FEATURES AND BENEFITS

FOR BEST PERFORMANCE:
  • MEADOW-PATCH T2 is recommended for concrete repairs only.
  • Not intended to be used as a self-leveling underlayment or topping; T2 is designed as a trowel down repair mortar.
  • Do not apply below 45°F (7.2°C) or above 90°F (32°C) or when rain is imminent.
  • Do not bridge moving cracks. Extend existing control and expansion joints through MEADOW-PATCH T2.
  • For large areas with no control, expansion or construction joints, refer to ACI guidelines.
  • Do not exceed a length-to-width ratio of 2 to 1 for the repair area.
  • Do not add any admixtures.
  • Exceeding liquid requirements shall result in reduced physical properties.
  • Realize that set time will decrease as the product, air, substrate and mixing liquid temperature increases and will be increased as the temperature decreases.
  • Do not use solvent-based curing compounds.
  • Featheredging may result in reduced durability and performance.
  • Maximum application thickness should not exceed 1" (25 mm).
  • Protect from conditions that may cause early water loss; high winds, low humidity, high temperature and direct sunlight. Early water loss is amplified in thin applications.
  • Realize that the use of extender aggregate will alter physical properties.
  • Failure to follow industry standard practices may result in decreased material performance.
  • Proper application is the responsibility of the user. Field visits by W. R. MEADOWS personnel are for the purpose of making technical recommendations only, and are not to supervise or provide quality control on the job-site.
  • 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 (2 parts powder to 1 part ACRY-LOK™ from W. R. MEADOWS). Allow slurry coat to become tacky prior to application of MEADOW-PATCH T2. Do not allow slurry coat to become tack free.

MIXING
Using a mortar type mixer, pour approximately 3/4 of the ACRY-LOK polymer 1-gallon (U.S.) jug into a clean mixing container. Slowly add powder and mix to a desired consistency using the remaining liquid polymer 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 77°F (25°C).

EXTENSION
Applications greater than 1'' (25.4mm) must be extended with 12.5 lbs. (5.68 kg) of 1/4'' washed, dry pea gravel. Applications greater than 2'' (50.8mm) must be extended with 25 lbs. (11.36 kg) of 3/8'' washed, dry pea gravel.

PLACEMENT
Apply MEADOW-PATCH T2 into the repair zone substrate by compacting the material well against the properly prepared substrate. Finish surface with steel or wood trowel, or sponge float. Never re-temper.

CURING
Cure MEADOW-PATCH T2 immediately following application using a suitable water-based curing compound from W. R. MEADOWS, or in accordance with ACI 308. W. R. MEADOWS recommends 2250-WHITE or 1130-CLEAR for curing. (Do not use solvent-based curing compounds.) When conditions exist for rapid early water loss, the use of EVAPRE™, an evaporation retardant from W. R. MEADOWS, is also recommended.

SAFETY AND TOXICITY
Avoid direct contact with this product, as it may cause skin and eye irritation. Utilize gloves and safety glasses to minimize direct contact. Avoid inhalation of dust. Inhalation may cause respiratory irritation and/or lung disease (silicosis). This product contains silicon dioxide, which is classified by the IARC and NTP as probably carcinogenic to humans (IARC Group 2A). The use of NIOSH approved respiratory protection is recommended in dusty environments. Refer to Product Material Safety Data Sheet for complete health and safety information.
Keep product out of reach of children.
