Part 2: Products

2.1 Pigmented Floor Coatings & Clear Top Coats

A. Manufacturer: Laticrete International, Inc. 1 LATICRETE Park North, Bethany, CT 06524 P:203-393-0010

PERK® primer-sealer/finish coatings, pigmented or clear, both decorative and protective, are a new generation of fast-curing, two-component, polyaspartic aliphatic polyurea products for interior or exterior use over properly prepared concrete and metal substrates. They have excellent penetration and bond strength to properly prepared surfaces and are UV resistant, light stable, and abrasion, impact, and wear resistant with flexible properties. They have good splash and chemical-spill- resistant properties involving commercial and household cleaners, pool water treatment products, and hot tires. They are available in a range of solids contents and low to 0 VOC formulations.

2.2 Properties

A. PERK System exhibit the following cured system properties.
1. Property Profile for the PERK® Product System Polyaspartic Coatings:
a. CS-17 Taber Abrasion Wheel, 1,000 gram load; 1,000 revolutions
b. Liters of sand to erode 1 dry mil coating
c. Average of generic coatings surveyed
d. NR-Not Recommended
2. Chemical Resistance:
a. Consult L&M for Chemical Resistance and Performance charts for specifics

Part 3: Execution

3.1 Inspection

A. General
1. Examine the project area and take note of any conditions detrimental to the proper and timely completion of the work. Do not proceed with the work until unsatisfactory conditions have been corrected by the contractor in a manner acceptable to the architect.

3.2 Preparation

A. Protection of Surfaces not Scheduled to be Coated
1. Protect surrounding areas and surfaces not scheduled to be coated from damage during surface preparation and application of coatings
2. Immediately remove coatings that fall on surrounding areas and surfaces not scheduled to be coated.
B. Patching & Joint Preparation
1. Prior to application, existing substrate shall be examined for any cracks, spalls, holes, etc. These must be treated with adequate crack filler/repair materials exhibiting properties equal to proprietary polyurea based crack repair system from Laticrete International, Inc. Contact manufacturer for additional information.
2. Functional, control or expansion joints can be partially or completely filled with a premium-grade, high-performance, moisture-cured,1-component, polyurethane-based, non-sag elastomeric sealant exhibiting minimum elongation qualities of 100%. Contact manufacturer for additional information
C. Preparing Concrete Surfaces
1. Before application the receiving surface must be deemed structurally and mechanically sound, clean, and dry. Proper surface preparation is required for decorative-concrete, thin- film “Class-A-type” flooring systems or sealer/finish coatings. This is best achieved with mechanical grinding ma- chines using diamond heads achieving a final 50- to 120-grit profile. Recommended surface profile is SP-2, Reference ICRI Technical Guideline No. 03732.
2. All receiving surfaces must be free of previous coatings, sealers, curing compounds, water repellents, laitance, efflorescence, oils, fats, grease, waxes, and residues from cleaning compounds, non-visible soluble salts, and any other impediments to adhesion. The resulting surface must be a neutral PH 7.
3. The rising moisture vapor emission rate is recommended by the manufacturer to not exceed 3 pounds per 1,000 square feet (3 lb/1,000 ft²) over a 24-hour period as measured by the calcium chloride test method, ASTM F-1869. Up to 6 pounds per 1,000 square feet is acceptable provided a minimum of 3-coats and 11 mil DFT. For substrates exceeding 6 pounds per 1,000 square feet, a manufacturer approved moisture barrier primer may be utilized. Contact the manufacturer for more details. L&M does not warranty the use of such methods for high moisture content floors exceeding 3 pounds per 1,000 square feet (3 lb/1,000 ft²) over a 24-hour period and any moisture barrier primer system employed is done solely at the discretion of the applicator.
4. The relative humidity in the slab must not exceed 80 percent. Any repairs that are not associated with normal cleaning and surface preparation work (i.e., cracks, chips, pitted/severe spalls deemed non-structurally sound or have levelness issues) must be properly addressed and remedied prior to application of the coating due to the fact that coatings follow the contours of the existing substrate. All spalls and cracks should be repaired in accordance with ICRI standards.
