MIXING INSTRUCTIONS
SAND MIX
——————————————————
For overlaying concrete and as a bedding mix and joint
grout for flag-stone, slate or brick walkways and patios.
For applications 1/2 inch to 2 inches (50 mm) in thick-
ness.
PREPARATION:
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 Sand Mix.
For thicknesses less than 2 inches and toppings, use:
1 part of Portland Cement with 3-4 parts of concrete sand
or general purpose sand,
MIXING:
Place material into mixer. 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.
FINISHING:
Level with a screed and allow the bleed water to evap-
orate. Use a float to remove surface imperfections and
trowel to a smooth finish. For a rougher surface, use a
broom. 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 temper-
ature, 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, or cover with
plastic for several days as needed. In cold weather
adequately cover and keep from freezing for a minimum
of 24 hours.
PREPARED CONCRETE MIX
——————————————————
SAKRETE® Portland Cement Type I-II is used to make
concrete where 2-inch thickness or more is needed to
build or repair walks, floors, footings, patios, setting posts
and poles.
• You will need approximately seven (7) gallons of water
• 6-80 lb. Bags of pre-mix concrete
GENERAL PURPOSE CONCRETE
USING SAND & GRAVEL
——————————————————
Use the following mix proportions to make general pur-
pose concrete:
Mix together
• 1 part cement (This bag contains 94 lbs. or 1 cu. ft.).
• 2 parts concrete sand or general purpose sand (160-
180 lbs.).
• 3 parts gravel or stone (240-300 lbs., 3/4" recommend-
ed).
Add approximately 6 gallons of clean water. Mix until
uniform, workable consistency.
Concrete will remain workable for at least 1 hour.
To aid curing, spray surface lightly with water 2 or 3
times per day for 3 days.
One 94 lb. bag of Portland Cement makes 4.5 cubic feet
of concrete.
• Use an 8-1/2 x 12" square nose shovel
• Portland cement, gravel (or round stone), and masonry
sand
• Put five (5) gallons of water into the mixing drum
• Add 18 shovels full of gravel (or round stone) – 3/4” rec-
ommended
• Add six (6) shovels full of Portland cement
• Slowly add 12 shovels full of masonry sand
•
NOTE: WATER WILL VARY ACCORDING TO MOIS-
TURE CONTENT OF SAND & GRAVEL
• Add water (if needed) slowly to obtain desired consis-
tency
WILL YIELD 4.5 CU. FT. OF CONCRETE
• Put five (5) gallons of water into the mixing drum
• Add four (4) 80 lb. Bags of pre-mix concrete
• NOTE: Mixture will be very sloppy
• Slowly add the two remaining bags of 80 lb. Pre-mix
concrete
• Add water slowly to obtain desired consistency
WILL YIELD 4.5 CU. FT. OF CONCRETE
