All physical properties are
laboratory based, onsite testing may result in different values due to
environmental, mixing and curing procedures.
The product is currently under evaluation by an independent laboratory
for comprehensive testing. |
SHELF LIFE

YIELD
50 LB. (22.7 kg) bag yields: 0.44 cu. ft.
Yields listed above are based on 3.5 quarts (3.30 liters) of water per 50 lb.
(22.7 kg) bag and will vary based on substrate profile, aggregate, variations in
mix water amounts and waste/rebound. Field trials should be performed to
determine yields based on job-site conditions.

SURFACE PREPARATION
Perform surface preparation in accordance with ICRI Technical Guidelines No.
03730. Mechanically abrade existing substrate to remove all unsound concrete,
but do not use excessive force, which may cause micro fracturing. Substrate must
be structurally sound and free of any contaminants that will adversely affect
bond. Prepared surface must be dust-free and have a sufficient profile to ensure
adequate mechanical lock. Saw cut perimeter of repair zone to a depth of
¼" to avoid featheredging.
Completely exposed all reinforcing steel, ensuring a
minimum clearance of ¾" behind reinforcing steel. Perform reinforcing
steel preparation in accordance with ICRI Technical Guidelines No. 03730.
Pre-soak repair zone prior to application of MEADOW-CRETE
GPS to a saturated, surface dry (SSD) condition and free of standing water.
HAND APPLICATION
Prime SSD substrate with a slurry coat (2 parts MEADOW-CRETE GPS powder to 1
part water). For enhanced bonding, use SEALTIGHT ACRY-LOK instead of water.
Allow slurry coat to become tacky prior to application of MEADOW-CRETE GPS.
MIXING
Mix only complete bags. Using a mortar type mixer, pour 3.5 –3.75 quarts
(3.30-3.54 liters) per 50lb. (22.7 kg.) bag in mixer. Slowly add MEADOW-CRETE
GPS. Mix for 3-5 minutes or until homogeneous and lump-free. Do not over mix.
MACHINE PLACEMENT
Use low-pressure, wet spray equipment. Follow industry standard nozzle
procedures for removal of rebound, spray angle, compaction behind reinforcing
steel and appropriate reinforcing steel cover, etc. Cut surface face to desired
configuration. Finish with a wood, steel or sponge float. Do not overwork.
HAND PLACEMENT
Compact MEADOW-CRETE GPS into properly prepared SSD substrate prior to bulk
placement. Finish surface with a wood, steel or sponge float. MEADOW-CRETE GPS
may be applied up to 3" horizontally and vertically and 2" overhead,
dependent on patch size and configuration. Do not overwork.
CURING
Cure in accordance with ACI 308. Cure MEADOW-CRETE GPS immediately following
application using a suitable water-based curing compound such as SEALTIGHT 2250
or 1130. W.R. MEADOWS recommends the use of an evaporation retarder, such as
SEALTIGHT EVAPRE when severe application conditions exist.
LIMITATIONS
Do not apply MEADOW-CRETE GPS when the temperature is expected to be below 45°F
(7°C) within 24 hours or when rain is imminent. Mix only full bags. Protect
product from early loss in severe application conditions, low humidity, and high
temperature and/or from winds. Do not re-temper or over work product. Do not
featheredge. For industrial use only by professional contractors.
SAFETY and TOXICITY
Avoid inhalation of dust. Avoid direct contact with this product. Utilize gloves
and goggles to minimize direct contact. If contact occurs, wash affected areas
with mild soap and water. Keep product out of reach of children. For industrial
use only. Refer to Material Safety Data Sheet for complete Health and Safety
Information.
