D. Colors: [As selected by Architect from manufacturer's full range] [Match Architect's samples] [As indicated in color schedule]

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. Verify suitability of substrates, including surface

conditions and compatibility with existing finishes and primers. Where acceptability of substrate conditions is in question, apply samples and perform in-situ testing to verify compatibility, adhesion, and film integrity of new paint application.

1. Report in writing conditions that may affect application, appearance, or performance of paint.

B. Substrate Conditions:1. Maximum Moisture Content of Substrates: When measured with an

electronic moisture meter as follows:i. Concrete: 12 percent for acrylic and water-based products



ii. Block work: 12 percent for acrylic and water-based productsiii. Calcium Silicate/Cement Board: 12 percent for acrylic and water-

based productsiv. Plaster: 12 percent for acrylic and water-based products

2. Calcium Silicate/Cement Board: Verify that finishing compound is sanded smooth.

3. Plaster Substrates: Verify that plaster is fully cured.

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; application of coating indicates acceptance of surfaces and conditions.’

3.2 PREPARATION

A. Comply with manufacturer's written instructions and recommendations applicable to substrates 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.

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

surface-applied protection.C. Clean substrates of substances that could impair bond of coatings, including dust,

dirt, oil, grease, and incompatible paints and encapsulants.1. Remove incompatible primers and reprime substrate with compatible primers or apply tie coat as required to produce coating systems indicated.

D. Concrete Substrates: Remove release agents, curing compounds, efflorescence, and chalk. Do not coat surfaces if moisture content or alkalinity of surfaces to be

coated exceeds that permitted in manufacturer's written instructions.1. Clean surfaces with pressurized water. Use pressure range of 1500 to 4000 psi.2. Use vacuum assisted centrifugal shot blasting or Dimond disc grinding (of

suitable size) for preparing concrete walls/ceilings.E. Masonry Substrates: Remove efflorescence and chalk. Do not coat surfaces if

moisture content, or alkalinity of surfaces or if alkalinity of mortar joints exceeds that permitted in manufacturer's written instructions.

1. Clean surfaces with pressurized water. Use pressure range of 500 to 1200 psi



3.3 APPLICATIONA. Apply all interior paints according to manufacturer's written instructions

and recommendations.1. Use applicators and techniques suited for painting and substrate indicated.2. Coat surfaces behind movable equipment and furniture same as similar

exposed surfaces. Before final installation, coat surfaces behind permanently fixed equipment or furniture with prime coat only.

3. Coat back sides of access panels, removable or hinged covers, and similar hinged items to match exposed surfaces.

4. Do not apply coatings over labels of independent testing agencies or equipment name, identification, performance rating, or

nomenclature plates.

B. If undercoats or other conditions show through final coat, apply additional coats until cured film has a uniform coating finish, color, and appearance.

C. Apply paint to produce surface films without cloudiness, spotting, holidays, laps, brush marks, runs, sags, ropiness, or other surface imperfections. Produce sharp glass lines and color breaks.

3.4 FIELD QUALITY CONTROLA. Dry Film Thickness Testing: Owner may engage the services of a qualified testing and

inspecting agency to inspect and test coatings for dry film thickness.1. Contractor shall touch up and restore coated surfaces damaged by testing.2. If test results show that dry film thickness of applied coating does not comply

with coating manufacturer's written recommendations, Contractor shall pay for testing and apply additional coats as needed to provide dry film thickness that complies with coating manufacturer's written

recommendations.

3.5 CLEANING AND PROTECTION A. At end of each workday, remove rubbish, empty cans, rags, and other discarded

materials from Project site.B. After completing coating application, clean spattered surfaces. Remove spattered

coatings by washing, scraping, or other methods. Do not scratch or damage adjacent finished surfaces.

C. Protect work of other trades against damage from coating operation. Correct damage by cleaning, repairing, replacing, and recoating, as approved by Architect,

and leave in an undamaged condition.D. At completion of construction activities of other trades, touch up and restore

damaged or defaced coated surfaces.



Notes:

* For Educational and Healthcare projects only

** For projects in localities where the local green building regulation is accepting VOC content determination by ISO 11890-2 or for products for which reasonably accurate VOC content determination is not practical, VOC content values as per ISO 11890-2 is acceptable
