3.3 PRIMING - SIKA ONLY

A. Concrete (<4% moisture content by weight, measured with Tramex CMEXPERT-Non- Destructive Concrete Moisture Meter CMEX 1210:

1. For systems requiring primer, apply Sikafloor FTP primer at 300 sf/gal. with a flat

squeegee or roller and work well into the substrate to insure adequate penetration and sealing. Puddles are to be avoided.

2. Refer to data sheet for more detailed information, or consult Sika for other primer options.

4. Add the 1 gallon of Sikafloor FTP, Part “R” to the 1.25 gallons of Part “H” in the short filled Part “H” pail. Mix thoroughly with a mechanical mixer (Jiffy) for 3 minutes.

5. This mixture will appear as a light olive green color. 6. Slowly add 1.25 gallons of potable water to the mixture under agitation. 7. Mix for an additional 2 minutes until the mixture is fully dispersed. 8. Fully dispersed material will appear as light green in color. 9. Allow primer to cure a minimum of 3-4 hours at 70°F and 50% RH or until tack free

before applying base coat.

B. Metal: Consult manufacturer for selection of primer. 3.4 DETAILING

A. SIKA

1. Non-Structural Cracks up to 1/16 inch: Apply a detail coat of Sikalastic 720 Base at 23

mils wet, 4 inches wide, centered over the crack. Allow to become tack free before overcoating.

2. Cracks and Joints over 1/16 inch up to 1 inch: Rout and seal with Sikaflex 2c or 1a sealant and allow to skin over and cure. Apply a detail coat of Sikalastic 720 Base at 23 mils wet, 4 inches wide, centered over crack. Allow to become tack free before overcoating.

3. Joints over 1 inch: Treat as expansion joints and brought up through the Sikalastic Traffic System and sealed with Sikaflex 2c or 1a sealant.

B. BASF

3. Route dynamic cracks and joints over 1/16 inch (1.6 mm) to minimum of 1/4 inch by 1/4 inch (6 by 6 mm) and clean. Install bond breaker tape or approved bond breaker material to prevent adhesion to bottom of joint. Prime joint faces only with sealant primer and fill with sealant. Fill joints deeper than 1/4 inch (6 mm) with backer rod and deep joint sealant. For cracks, apply sealant flush with adjacent surface. For expansion joints, apply sealant slightly concave.

4. Coat low movement sealed joints 1 inch (25 mm) or less with deck coating system. 5. Do not coat expansion joints exceeding 1 inch (25 mm) wide or any sealant joints which

C. Level substrates by grinding high spots or filling low spots with latex cementitious subfloor filler as required.

D. Broom clean or vacuum the surfaces to be covered, and inspect the substrates. E. Verify substrates are smooth, level, at required finish elevation, and are ready to receive

resilient tile flooring and base. F. Bring discrepancies to the attention of the Architect and do not proceed until such

discrepancies are corrected. G. Conduct moisture test in accordance with ASTM F1869 - maximum allowable amount of

moisture emission from floor is 3.0 pounds per 1,000 square feet in 24 hour period, and shall not exceed maximum allowable moisture content as allowed by flooring manufacturer.

H. Starting Work indicates acceptance of existing conditions.

3.3 INSTALLATION A. General:

1. Install materials only after finishing operations, including painting, have been completed and after permanent heating and cooling system is operating.



2. Verify that moisture content of concrete slabs, building air temperature, and relative humidity are within the limits recommended by the manufacturers of the materials used.

B. Installing Resilient Tiles:

1. Place units with adhesive cement in compliance with the manufacturer's recommendations.

a. Butt units tightly to vertical surfaces, nosings, edgings, and thresholds. b. Scribe as necessary around obstructions and to produce neat joints. c. Place tiles tightly laid, even, and in straight parallel lines. d. Extend units into toe spaces, door reveals, and in closets and similar

spaces. 2. Lay units from center marks established with principal walls, discounting minor

offsets, so that units at opposite edges of the room are of equal width. a. Adjust as necessary to avoid use of cut widths less than 3 inches wide at

edge of space. b. Lay units square to axes of the room or space.

3. Match units for color and pattern by using materials from cartons in the same sequence as manufactured and packaged.

4. Lay in alternating pattern with grain in all units running 90 degrees from adjacent unit.

5. Place joining and edge finish moldings, including reducer strips tightly butted to units and secured with adhesive, providing at all unprotected edges unless otherwise shown.

C. Installing Base:

1. Install base where shown on the Drawings in accordance with manufacturer’s instructions.

2. Use factory-preformed exterior corners, and factory preformed or job-mitered interior corners.

3.4 CLEANING AND PROTECTING A. Remove excess adhesive and other blemishes from exposed surfaces, using neutral

cleaner recommended by the manufacturer of the resilient materials.
