inches (50 mm) in thickness.
SAFETY:
READ and UNDERSTAND the Material Safety Data Sheet (MSDS) before using
this product. WARNING: Wear protective clothing and equipment. See HMIS
block. For emergency information, call CHEMTREC at 800-424-9300
or 703-527-3887 (outside USA). KEEP OUT OF REACH OF CHILDREN.
PREPARATION:
(Fig. 1) When repairing concrete, square up the area to be patched. Remove
all loose and foreign material. Clean the surface thoroughly. Dampen the area
to be repaired just prior to applying SAKRETE® Sand Mix.
MIXING:
Empty the contents into a mortar box, wheelbarrow or mechanical mixer.
When mixing by hand, form a crater for adding water. (See table below) If
too stiff, add more water a little at a time. AVOID A SOUPY MIX. Excess water
reduces strength and durability and can cause cracking. In cold weather
use warm water to accelerate the set. Use cold water to slow the set in hot
weather.
Water amounts are approximate
PLACEMENT:
Place and consolidate the SAKRETE® Sand Mix. Work the material into voids
then level the surface with a straight edge board.
FINISHING:
Level with a screed and allow the bleed water to evaporate. Use a float to
remove surface imperfections and trowel to a smooth finish. For a rougher
surface, use a broom. Refer to ACI 302. Finishing cementitious materials too
early, or over-working the materials can cause dusting, cracking, scaling and
a weak surface.
CURING:
Curing means maintaining proper moisture and temperature. Account for local
environmental conditions when selecting the curing method. High heat, low
humidity or wind will increase the evaporation of water. Keep the surface
damp, using a sprinkler, wet burlap, Sakrete Cure ‘N Seal or cover with plastic
for several days as needed. In cold weather adequately cover and keep from
freezing for a minimum of 24 hours. Refer to ACI 308.
STORAGE:
Store in a tightly closed container off the floor in a dry place.
When used as directed and in accordance with ASTM C 387 Specification,
60 lb. SAKRETE® Sand Mix exceeds 5,000 psi after 28 days.

Compressive Strength
7 day 3,000 psi (21 Mpa)
28 day 5,000 psi (34 Mpa)
COVERAGE:
To determine coverage: Multiply Length x Width x Thickness all in feet
(meters) = cubic feet (cubic meters): divide by 0.45 cubic feet (0.012 cubic
meters) per bag = Number of 60 lb. (27.2 kg) bags needed for given job.
NOTE: Convert all measurements in inches (mm) to feet (meters).
4 inches (100 mm) = 0.33 feet (0.1 m)
COVERAGE:
To determine the number of bags needed: Multiply (length x width x depth),
divided by yield from chart above.
