TECHNICAL DATA
APPLICABLE STANDARDS
ASTM International - ASTM C387 Standard Specification for
Packaged, Dry, Combined Materials for Mortar and Concrete
QUIKRETE
®
Sand/Topping Mix exceeds the compressive strength
requirements for high strength mortars per ASTM C387. Typical
compressive strengths are:
• 3000 psi (20.7 MPa) at 7 days
• 5000 psi (34.5 MPa) at 28 days
INSTALLATION
SURFACE PREPARATION
When using Sand/Topping Mix to resurface damaged concrete
surfaces 1/2" - 2" (12.7 - 51 mm) thick dig a small trench along the
edge of the damaged surface so that forms can be set in place level
with the old concrete surface. It is important to form a solid base for
the new topping.
Remove all broken and loose concrete. Clean the surface thoroughly
with QUIKRETE
®
Concrete & Asphalt Cleaner.
ADMIXTURES
For patches less than 1" (25.4 mm) thick, replace part of the mixing
water with QUIKRETE
®
Concrete Acrylic Fortifier #8610 for improved
bonding. Add the QUIKRETE
®
Concrete Acrylic Fortifier directly to the
mix at the rate of 3 pt (1.4 L) per 60 lb (27.2 kg) bag or 1/2 gal (1.9 L)
per 80 lb (36.3 kg) bag.
MIXING
NOTE:
• For applications 1" - 2" (25.4 - 51 mm) thick, use specified bonding
agent
• For applications less than 1" (25.4 mm) thick, use specified
admixture
MACHINE MIXING
QUIKRETE
®
Sand/Topping Mix can be mixed in a barrel type
concrete mixer or a mortar mixer. Choose the mixer size most
appropriate for the size of the job. Allow at least 1 cu ft (28 L) of mixer
capacity for each 80 lb (36.3 kg) bag of QUIKRETE
®
Sand/Topping
Mix to be mixed at one time
• For each 80 lb (36.3 kg) bag of QUIKRETE
®
Sand/Topping Mix to
be mixed, add approximately 8 pt (3.8 L) of fresh water to the mixer
• Turn on the mixer and begin adding bags of Sand/Topping Mix to
the mixer
• If the material becomes too difficult to mix, add additional water until
a workable mix is obtained
Note - Final water content should be 8 - 12 pt (3.8 - 5.7 L) of water
per 80 lb (36.3 kg) bag of Sand/Topping Mix. For other bag sizes, use
Table 1 to determine water content.
HAND MIXING
• Empty Sand/Topping Mix bags into a suitable mixing container
• For each 80 lb (36.3 kg) bag of mix, add approximately 8 pt (3.8 L)
of clean water. Work the mix with a shovel, rake or hoe
