Description
SEALTIGHT MEADOW-PATCH 5 is a one component, cementitious, very fast setting restoration / repair mortar designed for vertical, overhead and horizontal applications. This very rapid setting, low slump repair mortar may be trowelled, shaped, molded, and shaved for 4-6 minutes before taking an initial set. MEADOW-PATCH 5 is an excellent patching solution for difficult vertical / overhead applications without using expensive and intricate forming techniques.

USES
SEALTIGHT MEADOW-PATCH 5 is easy to mix and apply. This very fast setting, low slump mortar is designed to minimize downtime. Because of its versatility MEADOW-PATCH 5 can be used vertically, horizontally, or overhead. Whether the installation is interior or exterior; MEADOW-PATCH 5 is an excellent choice for fast repairs above grade, below grade, or on grade. Because of its non-sag consistency and extremely fast setting times, MEADOW-PATCH 5 is well suited for underwater concrete repair.

COVERAGE
MEADOW-PATCH 5 yield per 50 lb. bag is 0.45 ft³ (0.013m³)

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.

MIXING
MEADOW-PATCH 5 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 3-5 minutes at 77° F (25° C). Do not over mix or re-temper.

PLACEMENT
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 5 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 increase.

CURING
MEADOW- PATCH 5 must be cured in accordance with ACI 308 utilizing a suitable curing compound such as SEALTIGHT 1100 Series or SEALTIGHT 1200 Series. Protect from rapid early water loss.

SHELF LIFE
1-year, when left in original, unopened packaging and stored indoors.
