PART 3 EXECUTION
 
3.1
CONCRETE PLACEMENT
A.
Follow ACI recommendations for placement of concrete for normal or flat floors.
B.
Where heavy-duty, flat or super-flat concrete floors are scheduled, provide concrete with the following additional requirements:
1.
Maximum slump of five inches.
2.
Maximum air content of three percent (3%).
3.
Do not use set accelerating admixtures, such as calcium chloride.
3.2
EXAMINATION
A.
Verify by examination that surfaces are acceptable to receive the shake-on floor hardener. Notify the Architect if surfaces are not acceptable to receive material.
3.3
INSTALLATION
 
** NOTE TO SPECIFIER ** Option One: Delete if not required.
 
A.
Following the use of the highway straightedge and after bleed water has dissipated, apply up to all of the required shake-on hardener per application. Distribute evenly by use of a mechanical spreader to be assured of maintaining specified flatness values and indicated material amount.
 
** NOTE TO SPECIFIER ** Option Two: Delete if not required.
 
B.
Following the concrete leveling operation, and as soon as the concrete will support an operator and machine without disturbing the level, float the surface with a mechanical float fitted with float shoes. Following floating, apply up to 2/3 of the total amount of the hardener with a mechanical spreader to assure uniform application. Do not apply dry shake onto surface when bleed water is present. Once the shake has absorbed sufficient moisture (indicated by darkening of the material), apply remainder of the shake. Do not apply dry shake on concrete surface when bleed water is present. Use L&M E-CON, evaporation retardant, to eliminate surface crusting.
C.
Use finishing machines to compact surface by a third mechanical floating it time and setting characteristics will allow. Use E-CON to reduce plastic shrinkage cracks.
D.
As surface further stiffens, hand or mechanically trowel with raised blades to desired finish. Remove all marks and pinholes.
3.4
CURING
A.
Cure finished floors using approved by hardener manufacturer. Cure per manufacturer recommendations
3.5
CONTROL JOINTS
A.
Form or saw cut control joints as soon as the surface permits the weight of the saw without causing topping edges to ravel.
B.
After concrete has fully cured, fill joint wells with JOINT TITE 750, as two-component, polyurea control joint filler, according to manufacturer's recommendations.
3.6
PROTECTION:
A.
Cover floors and keep free of traffic and loads for a minimum of seven days after completion.
