PRODUCT DESCRIPTION
Rapid Patch
®
Multi-Purpose Repair is a
fast-setting, high-performance, multi-use
blend of hydraulic cement, fine
aggregates, and special additives used for
concrete repair and new construction,
including casting, anchoring, grouting, and
wet environments. Adheres to concrete,
stone, masonry, and stucco. Mix with
water for applications from feather-edge to
4 in. (10 cm).
WHEN/WHERE TO USE
• Interior or exterior
• Vertical and horizontal
• Residential and commercial
• Patching and repairs of concrete slabs,
curbs, steps, driveways, and sidewalks
• Structural concrete repairs
• Doweling and anchoring
• Industrial grouting
• When high early strength and fast
setting is required
ADVANTAGES

TECHNICAL DATA
PREPARATION
Read all directions before starting work.
Proper surface preparation is crucial to
achieving a successful application. All
surfaces must be structurally sound.
Remove all dust, acid, waxes, sealers, old
adhesive residue, curing compounds, oil,
paint, or any other foreign materials that
could inhibit bond. Condition all materials
to 65°F-75°F (18°C-24°C) 24 hours prior
to installation. Prior to material placement,
dampen the area to be repaired with clean
water to a saturated-surface-dry (SSD)
condition. Organize mixing and application
to be as close to the work area as
possible to maximize the working time
with this accelerated setting material. Any
rust on exposed rods should be removed
by mechanical methods, wire brushing,
sandblasting, or scraping.
MIXING
Mix only the amount that can be applied in
15 minutes. The use of a ½” heavy-duty
drill (300 RPM or less) with paddle mixer
or a mortar mixer is recommended,
although hand-mixing smaller amounts
can also be used. Avoid high speed
mechanical mixing which can entrap air
into the mixture. Choose the mixer size
most appropriate for the size of the job to
be done. Allow at least 1 cu. ft. (28 L) of
mixer capacity for every 50 lb. (22.7 kg)
bag of product.
1. In a clean container, with clean tools,
mix with cool water only, no bonding
additive is needed. Place ¾ of the
desired mixing water, start mixer, then
slowly add the dry material. After all of
the powder has been added, slowly add
the remaining ¼ water until the desired
consistency is achieved. The mix
consistency should be determined by
the project application. Vertical and
overhead applications require a firm,
plastic, trowelable consistency, while
grouting and anchoring a more flowable
consistency.
2. Mix to a uniform, lump-free consistency,
typically 1-3 minutes. If additional water
is needed for your application, add in
small doses. Material becomes stiff in
approximately 10-15 minutes, so mix
only what you plan on using in this time
period.
3. Do not retemper, exceed water limits, or
add any materials other than clean
potable water. Clean mixer often to
prevent buildup of material. Elevated
temperatures will shorten the working
time. Lower temperatures will delay set
times. The use of cold water at high
temperatures or warm water at low
temperatures will aid in adjusting the
mix temperature.
APPLICATION
Ideal application conditions are when air,
material, and substrate temperatures are
between 45°F-90°F (7°C-32°C) within 24
hours of application and placement, and
rain is not forecast 24 hours after. Set
times will vary in extremely hot or cold
conditions. Do not apply over concrete
cured less than 28 days or surfaces that
are frozen or contain frost.
1. Apply from feather-edge minimum to 4
in. (10 cm) maximum thickness. For
vehicle traffic or heavy loads, the
minimum thickness will vary. When
used as an overlay, a test area or mock
-up is recommended to evaluate
suitability for the application.
2. Shovel or place mixture immediately
