b. Other Items: Architect will designate items or areas required. 2. Final approval of color selections will be based on mockups.

a. If preliminary color selections are not approved, apply additional mockups of additional colors selected by Architect at no added cost to Owner.

A. Do not apply materials when surface and ambient temperatures are outside the temperature ranges required by the paint product manufacturer.

B. Do not apply exterior coatings during rain or snow, or when relative humidity is outside the hu-midity ranges required by the paint product manufacturer.

C. Minimum Application Temperatures for Latex Paints: 7 degrees C (45 degrees F) for interiors; 10 degrees C (50 degrees F) for exterior; unless required otherwise by manufacturer's instructions. D. Minimum Application Temperature for Varnish Finishes: 18 degrees C (65 degrees F) for interior

or exterior, unless required otherwise by manufacturer's instructions.

E. Provide lighting level of 860 lx (80 ft candles) measured mid-height at substrate surface. F. Other Considerations:

1. Install prior to adhesively applied flooring and wall covering. 2. Install prior to carpet and acoustical material.

3. Schedule installation to minimize accumulation of air contaminants that cannot be removed prior to occupancy.

4. Air out construction with 100% outside air. a. Do not recirculate prior to occupancy.

b. Ventilate during installation. Seal return air ducts and use direct exhaust to outdoors. G. Environmental Criteria

1.6 EXTRA MATERIAL

A. Deliver extra material to Owner. Furnish extra paint materials that match products as described below, packaged with protective covering for storage and identified with labels clearly describing contents. Contractor shall provide an amount equal to 2% (or one unopened gallon of each color used) of the installed material provided within the Scope of the Work (provide amount for each color used on project). Surplus material is a requirement of the Work and Final Payment will not be issued until all material is provided to the Owner.

2. For each coat in a paint system, products shall be recommended in writing by topcoat manufacturers for use in paint system and on substrate indicated.

C. Colors: As selected by Architect from manufacturer's full range.

PART 3 - EXECUTION

3.1 EXAMINATION

A. Examine substrates and conditions, with Applicator present, for compliance with requirements for maximum moisture content and other conditions affecting performance of the Work.

B. Maximum Moisture Content of Substrates: When measured with an electronic moisture meter as follows:

1. Fiber-Cement Board: 12 percent. 2. Wood: 15 percent.

C. Verify suitability of substrates, including surface conditions and compatibility with existing finishes and primers.

D. Proceed with coating application only after unsatisfactory conditions have been corrected. 1. Application of coating indicates acceptance of surfaces and conditions.

3.2 PREPARATION

A. Comply with manufacturer's written instructions and recommendations in "MPI Architectural Painting Specification Manual" applicable to substrates and paint systems indicated.

B. Remove hardware, covers, plates, and similar items already in place that are removable and are not to be painted. If removal is impractical or impossible because of size or weight of item, provide surface-applied protection before surface preparation and painting.

(17)

1. After completing painting operations, use workers skilled in the trades involved to reinstall items that were removed. Remove surface-applied protection.

3.3 APPLICATION

A. Apply paints according to manufacturer's written instructions and recommendations in "MPI Manual."

B. Apply paints to produce surface films without cloudiness, spotting, holidays, laps, brush marks, roller tracking, runs, sags, ropiness, or other surface imperfections. Cut in sharp lines and color breaks.

A. Protect work of other trades against damage from paint application. Correct damage to work of other trades by cleaning, repairing, replacing, and refinishing, as approved by Architect, and leave in an undamaged condition.

B. At completion of construction activities of other trades, touch up and restore damaged or defaced painted surfaces.
