MEADOW-PATCH 20 yield per 50 lb. bag is 0.45 ft. ³ (0.013m³)
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.
MEADOW-PATCH 20 requires approximately 4 quarts (3.78/L) of potable water per
50lb. (22.7kg.) bag. Mix material in manageable quantities to obtain a stiff,
lump-free consistency within 60 seconds. Do not mix more material than can be
placed and finished within 8-12 minutes at 77° F (25° C). Do not over mix or
The properly prepared SSD repair area should be brushed with a slurry coat just
before placing. Do not allow slurry coat to dry; immediately work MEADOW-PATCH
20 into the patch, compacting the material well against the substrate. Overfill,
if desired to allow for shaping, molding, or shaving. For deeper repair areas do
not exceed 2" per lift. As ambient, substrate & mix water temperature
increases set time decreases, and as temperature decreases set time will
MEADOW- PATCH 5 must be cured in accordance with ACI 308 utilizing a suitable
