B. Follow recommendations of ACI 302.1R-04 for subbase preparation and testing.
C. Follow recommendations of ACI 302.1R-04 and Manufacturer’s published installation guidelines for concrete mixture and concrete placing.
edit note: for suspended-slab conditions, consult the local BASF representative for special information.
D. PUMP, PLACE, OR OTHERWISE CONVEY BASE CONCRETE AT SLUMP NOT IN EXCESS OF 5 INCHES (127 MM) FOR SLAB ON GRADE. AFTER CONCRETE HAS BEEN PLACED, IMMEDIATELY SCREED, THEN BULLFLOAT SURFACE USING WOOD BULLFLOATS.
E. Do not apply surface hardener into bleed water. If excessive bleed water is present, remove standing water by dragging a hose across surface, using squeegee or other approved method.
3. Application
A. If more than 1.0 pound per square foot (4.9 kg/m2) of total surface hardener will be applied, apply material in 2 or more applications. Apply and integrate 1/2 to 2/3 of total amount of surface hardener on first application, and apply remaining portion on subsequent applications. Do not apply more than 1.0 pound per square foot (4.9 kg/m2) in 1 pass. Wood bullfloats are preferred.
B. Allow first application to absorb moisture from slab, then profile surface of slab with 8 foot (2400 mm) to 10 foot (3000 mm) wood bullfloat or modified highway straight edge perpendicular to direction on screeding. To maintain flatness, avoid shaking bullfloat handle.
C. When slab can support weight of finisher without leaving more than a 1/8 inch (3 mm) to 1/4 inch (6 mm) depression, float surface with a walk behind floating machine equipped with clip-on float blades. Hand-float edges with wood floats or darbies. Reprofile in both directions using modified highway straightedge to if necessary to achieve specified flatness.
D. Without delay, evenly apply remaining portion of surface hardener. Float surface again with clip-on float shoes, straighten if needed. If desired, pan float, followed by finish troweling. Do not use pan floats to incorporate surface hardener into base concrete; however, pan floats may be used for final floating to achieve flatter floors. Hand-float edges with wood or hand floats or darbies.
4. Troweling
A. As surface tightens further, gradually raise trowel blades to produce desired surface. Final finish to meet appearance of approved mock-up sample.
B. If blistering occurs during finishing operation, flatten trowel blades immediately. Refloat to “open” floor and rework blistered areas with hand floats. Delay raised troweling until no blisters occur.
5. Curing
A. At completion of final troweling, and when surface will not be marred, apply approved membrane curing compound approved by surface hardener manufacturer.
B. Keep floors protected and free of traffic and loads for minimum of 7 days after completion.
C. Maintain ambient temperature at 50 degrees F (10 degrees C) or above during curing period.
D. Do not water or moist cure, or cure with polyethylene.
6. Joints
OPTION 1: SEMI-RIGID EPOXY JOINT FILLER. If this option is selected, delete option 2 language below.
A. AFTER MINIMUM OF 90 DAYS, APPLY APPROVED (APPROVED MATERIAL AND COLOR) SEMI-RIGID EPOXY JOINT FILLER IN NON-DYNAMIC CONTROL AND SAW-CUT CONSTRUCTION JOINTS. PLACE JOINT FILLER PER JOINT FILLER MANUFACTURER’S RECOMMENDATIONS.
B. If joint filling is sooner than 90 days after slab placement, contact joint filler manufacturer for recommendations and precautions.
OPTION 2: Polyurea JOINT FILLER. If this option is selected, delete option 1 language above.
1. CONTACT BASF BUILDING SYSTEMS TECHNICAL SUPPORT OR YOUR LOCAL BASF BUILDING SYSTEMS REPRESENTATIVE FOR ADDITIONAL GUIDANCE WHEN POLYUREA JOINT FILLER IS SELECTED.
7. CLEANING
