Concrete Patch is available in 10 lb. (4.54 kg) cans, 4 per carton,
and in 50 lb. (22.68 kg) pails and bags, 49 bags per pallet. Stretch
wrapping available. Must be kept in dry storage area. Shelf life is

Coverage
|
|
Varies
with job site conditions and application technique. For estimating
purposes: at 1/4" (6 mm) thickness, 50 lbs. (22.68 kg) covers approximately
20 to 25 sq. ft.(1.8 to 2.3 m2) (0.5 cubic ft. (0.015 m3) of mixed
material). |
|
|
|
|
|
Surface
Preparation
|
|
All receiving
surfaces must be structurally sound, clean, free of dust, dirt,
silicones, paint products, efflorescence or any other contaminant
which could hinder bonding ability. Provide absorptive surfaces
on all substrates including smooth precast or formed concrete by
abrading the surface. Undercut the perimeter of the patching area
by a minimum thickness of 3/4 inch. The surface should be saturated
surface dry (SSD) without standing water.
|
| |
|
|
|
Mixing
|
|
Mechanically
mix with a slow speed drill to produce a smooth workable consistency.
Add clean potable water:
50 lbs.(22 kg): Add 3 to 4 quarts (2.7 to 3.8 ltr) water.
10 lbs.(4.5 kg): Add 1 1/4 to 1 3/4 pints (.6 to .8 ltr) water.
Do not overwater! Mixing time should not exceed 90 seconds.
Do not over air entrain by excessive mixing. Caution:
Super Concrete Patch is a fast setting material. Mix only enough material
that can be placed in 10 to 15 minutes. |
|
|
|
|
|
Application
|
|
Predampen patched
areas to control suction. Apply with trowel, forcing material firmly
into receiving areas to ensure a good bond. Build up deep fills
gradually. Slightly overfill patch and then shave with straight
edge before full set to conform to surrounding surfaces.
|
|
|
|
|
|
Clean
Up
|
|
After
completing work, clean all mixing equipment and application tools
immediately with water. During application, protect surrounding areas
from spills and splatters. Clean spills before they set. |
|
|
|
|
|
Limitations
|
|
Do
not apply to frozen or frost filled surfaces. Do not use when ambient
temperature exceeds 110° F (43° C) or will fall below 40° F (4° C)
within 48 hours after application. During periods of hot, dry or windy
weather, physical moist curing may be required.
