Visual 2
• Do not use more than 1 gal (3.8 L) of mixing water per bag
• Mixing must be completed in 3 - 4 minutes
Temperature of Water
Because of the rapid setting time, special precautions
must be taken as set times will fluctuate in extremely
hot or cold weather. Use cold water or water mixed
with ice cubes in severely hot weather. Use hot water
when mixing in severely cold weather.
Placing
• The forms, hole or sub-base should be thoroughly
dampened
• Fill the forms completely working from one end to
the other. Avoid partial depth lifts which could result
in cold joints
• Consolidate the material using hand tamping and/or
chopping with a shovel. It is particularly important to
compact around the edges of the forms or patches
• Screed the surface, and then apply a trowel or
broom finish as desired
Curing
FastSet
™
Concrete Mix is often placed in service within
a few hours after it sets, so conventional moist curing
methods are not practical. Sealing the surface with
QUIKRETE
®
Concrete Cure and Seal – Satin Finish
(No. 8730) after the concrete has hardened will ensure
proper curing and provide an additional measure
of protection against salt and water penetration.
Under hot, dry and windy placing conditions, all
concrete tends to lose moisture unevenly and may
develop plastic shrinkage cracks. The use of sheeting,
monomolecular films (either sprayed or rolled on), as
well as application of a very fine fog spray of water,
has been quite successful in arresting shrinkage
cracking.
Precautions
• During extremely hot or dry conditions, cold water
should be used to maintain mix at a moderate
placement temperature
• Mix no more than can be used in 20 minutes
