Color:
Gray
Preparation/Application:
1. Remove all loose concrete from the repair area by chipping with hammer
and chisel.
2. For a successful project, proper preparation is required. Air, mix and substrate
temperatures should be a minimum of 40ºF (10ºC).
3. Surfaces to be repaired must be sound and clean.
4. Remove all loose and foreign matter and any material such as sealers, paints,
oil, tree sap or glues that will interfere with bonding.
5. Dampen concrete surface just prior to applying Top ‘n Bond.
6. DO NOT USE A BONDING AGENT.
Concrete Repair:
Top n Bond can be used either as a trowel applied material to repair cracks
or level uneven surfaces or as a thin brush coat to blend existing repairs to a
uniform color.
Trowel Applied:
1. For a superior bond mix Top ‘n Bond to a wet soupy consistency and smear
(using a gloved hand) or brush the material onto the entire surface to be
repaired working the mix into cracks.
2. Allow to dry a few minutes before continuing.
3. Then mix Top n Bond to the correct consistency (see water chart) and place
and consolidate the mix.
4. Work into voids and level with a trowel.
5. Do not overwork as this may lead to dusting or cracking.
6. For applications thicker than 1/2” (13 mm) apply in layers allowing material
to harden between applications.
Brush Coat Application:
Using a soft paint brush or masonry brush, apply mix no more than 1/8” thick.
Refer to:
- ACI 305R Guide to Hot Weather Concreting
- ACI 306R Guide to Cold Weather Concreting
Mixing:
1. Add approximately half of the water (see table for water amount) to an empty
pail, then add material and mix. Add additional water as needed but AVOID A
SOUPY MIX.
2. When mixing less than the entire bag, mix 4.5 parts material with 1 part
water or enough to achieve a workable mix.
3. Excess water reduces strength and durability and can cause cracking,
dusting or scaling.
4. For improved mixing, mix in a 5 gallon pail using a power drill and a mortar
or paint mixing paddle. Add half of the required water to the empty pail, then
add material and mix. Add the remainder of water as needed.
5. If using in a “brush coat” application, mix 3.5 parts material with 1 part
water or until a stiff paint consistency is achieved.
Top ‘n bond concrete patcher
Sakrete Top ‘n Bond Concrete Patcher
is a polymer modified sand cement
repair mortar requiring only the
addition of clean potable water. For
applications from 1/2” (13 mm) to
feather edge. For refinishing,
patching and general repairs to
concrete/masonry.
Features:
• High Strength 5,000 psi
• Applications feather edge to 1/2” (13 mm)
• Open to foot traffic in 24 hours and vehicular traffic in 72 hours
• Interior/exterior applications
• Superior abrasion resistance
Use For:
• Repairing cracks in concrete slabs, driveways and sidewalks
• Leveling uneven concrete surfaces
• Curbs
• Stairs
• Ramps
• Concrete overlays
• Large masonry crack repairs
Yield/Water/Coverage:
To determine coverage: Multiply Length (feet) x Width (feet) x Thickness (inches)
and divide by 12. Then divide by the yield in the chart above to determine the
numbers of bags needed. See Calculator on Sakrete.com for assistance.
Yield and water are approximate.
Technical Data:
Compressive Strength ASTM C109
7 day = 4,000 psi (28 MPa)
28 days = 5, 000 psi (34 MPa)
Bond Strength ASTM C882
28 days = 1200 psi (8 MPa)
