Pro-Finish Crack Resistant Concrete

No. 1006-68

Uses: QUIKRETE

PRO-FINISH Crack

Resistant Concrete Mix has a unique

formulation, offering benefits such as:

• Significantly reduced cracking from drying

shrinkage

• Superior workability

• Air entrainment for improved freeze-thaw

durability

• Greater impact resistance

• Eliminates the need for wire mesh in typical

slab-on-grade applications, such as

driveways, floors, patios, and sidewalks

Composition and materials: QUIKRETE

PRO-FINISH Crack Resistant Concrete Mix is a

4000 psi (27.6 MPa) construction-grade

concrete, consisting of uniformly blended,

properly proportioned mixture of stone or gravel,

sand, Portland cement, alkali-resistant glass

fibers and other ingredients approved for use in

concrete.

Size: Available in 80 lb. (36.3 kg) bags

Yield: Each 80 lb. (36.3 kg) bag of QUIKRETE

PRO-FINISH Crack Resistant Concrete Mix will

yield approximately 0.6 ft

(17L) of mixed

concrete.

Technical Data: QUIKRETE

PRO-FINISH

Crack Resistant Concrete Mix exceeds the

compressive strength requirements of ASTM C-

387, “Standard Specifications for Packaged,

Dry, Combined Materials for Mortar and

Concrete.” A properly handled mix will exceed

2500 psi (17.3 MPa) in 7 days and 4000 psi

(27.6 MPa) in 28 days.

Mixing: QUIKRETE

PRO-FINISH Crack

Resistant Concrete Mix can be hand-mixed in a

suitable mixing container, or machine mixed in a

barrel-type concrete mixer or a mortar mixer.

Choose the mixer size most appropriate for the

size of the job to be done. Allow at least 3/4 cu

ft (21 L) of mixer capacity for each 80 lb. (36.3

kg) bag to be mixed at one time. Add

approximately 3 quarts (2.8 L) of clean water for

each bag to the mixer. Turn on the mixer and

begin adding the concrete to the mixer. If a

slump cone is available, adjust water content to

produce a slump of 2-3 inches (51-76 mm). Do

not exceed a total volume of 1-gallon (3.8 L) of

water per bag. If the material becomes too

difficult to mix, sparingly add water until a

workable mix is obtained. For a decorative

touch, add QUIKRETE

Liquid Cement Color

directly to the mixing water following the

directions on the bottle. QUIKRETE

Liquid

Cement Color is available in five colors: red,

brown, buff, charcoal and terra cotta.

Installation: Sidewalks and patios should be at

least 4" thick. For straight sides, construct the

forms out of 2x4's. For curves use ¼" plywood

and stakes. Dampen the sub-grade before

concrete is placed. Do not leave standing

puddles. Mix the concrete and shovel into the

form. After concrete has been compacted and

spread to completely fill the forms without air

pockets, 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. Use a darby or bull float

to float the surface; this levels any ridges and

fills 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" (25.4 mm) deep control

joints into the slab every 6' - 8' (1.8 - 2.4 m)

using a grooving tool. Allow 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.

Finishing: Any standard concrete finishing

technique is acceptable for use with

QUIKRETE

PRO-FINISH Crack Resistant

Concrete Mix. Concrete can be hand troweled,

power troweled, broom finished or finished with

other specialty finishes.

Curing: Proper curing increases the strength

and durability of concrete. QUIKRETE
