Installation Guide
• Be sure all material is wet; do not leave unabsorbed puddles of water.
• If a slump cone is available, adjust water to achieve a 3-in to 5-in
(75mm to 125mm) slump. Excess water will reduce strength and
increase permeability.
TEMPERATURE OF WATER
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
(not exceeding 120 F (48C) when mixing in severely cold weather.
APPLICATION
• Dampen the sub-grade before concrete is placed. Do not leave
standing puddles.
• Shovel or place the concrete into the form. Fill to the full depth of the
form.
• After the concrete has been compacted and spread to completely fill
the forms, strike off and float immediately.
• To strike off, use a straight board (screed), moving the edge back and
forth with a saw-like motion to smooth the surface. Then use a darby or
bull float to float the surface. This helps level any ridges and fill voids
left by the straight edge.
• Cut the concrete away from the forms by running an edging tool or
trowel along the forms to compact the slab edges.
• Cut 1-in (25mm) control joints into the slab every 6-ft to 8-ft (1.8m to
2.4m) using a grooving tool.
• Allow the concrete to stiffen slightly, waiting until all water has
evaporated from the surface before troweling or applying a broom
finish.
Note - For best results, do not overwork the material.
CURING
GENERAL
No special curing methods are required. QUIKRETE Q•MAX PRO is
often placed in service within a few hours after it sets, so conventional
moist curing methods may not be practical, however moist curing is still
beneficial. . For demanding structural applications, the ideal
circumstances for curing are ample moisture and moderate temperature
and wind conditions. Curing should be started as soon as possible and
should continue for a period of 5 days in warm weather, 70
F (21
C) or
higher, or 7 days in colder weather, 50 – 70
F (10 - 21
C).
ALTERNATE CURING METHODS
• QUIKRETE
®
Acrylic Cure & Seal – Satin Finish (No. 8730) provides
the easiest and most convenient method of curing concrete. Apply by
sprayer or roller after the final finishing operation when the surface is
hard. The surface may be damp, but not wet, when applying curing
compound. Complete coverage is essential.
• Other methods of providing proper curing include covering the surface
with wet burlap, keeping the surface wet with a lawn sprinkler and
sealing the concrete surface with plastic sheeting once the surface is
hard.
• If burlap is used, it should be free of chemicals that could weaken or
discolor the concrete. New burlap should be washed before use. Place
it when the concrete is hard enough to withstand surface damage and
sprinkle it periodically to keep the concrete surface continuously moist.
• Water curing with lawn sprinklers or hoses must be continuous to
prevent interruption of the curing process.
• Curing with plastic sheets is convenient. They must be laid flat,
thoroughly sealed at joints and anchored carefully along edges.
• Final appearance will be affected by the curing method used. Burlap
and plastic sheet may affect color in spots.
PRECAUTIONS
• WEAR IMPERVIOUS GLOVES, such as nitrile when handling
product.
• When used in structural elements, comply with the steel reinforcement
and additional requirements of applicable building codes.
• Curing compounds should not be applied if rain or temperatures below
50
F (10
C) are expected within 24 hours
• Use of QUIKRETE
®
Acrylic Cure & Seal – Satin Finish (No. 8730) or
another curing compound is not recommended during late fall in
northern climates on surfaces where de-icers will be used to melt ice
and snow. Using curing compounds at that time may prevent proper air
curing of the concrete, which is necessary to enhance its resistance to
damage caused by de-icers.
• Protect concrete from freezing during the first 48 hours. Plastic
sheeting and insulation blankets should be used if temperatures are
expected to fall below 32
F (0C).
• It is recommended that de-icers NOT be used during the first winter
season following the concrete application.
