A. Closely examine surfaces. Surfaces that are in question or that will affect the execution or quality of work shall be brought to the attention of the Architect before painting will begin.

B. The Architect will inspect preparation before the application of paint finishes.

C. Rework surfaces not properly prepared to receive paint finishes to the satisfaction of the Architect.

3.2 PREPARATION

A. Prepare surfaces in compliance with manufacturer's requirements for coatings to be applied.

B. Surfaces to be painted: All surfaces shall be clean and dry, free of foreign matter and contaminants. Use cleaning methods as appropriate or indicated; including pressure washing, scraping, sanding and wire brushing.

1. Utilize power scrapers, grinders and wire brushes carefully to minimize damage to substrate.

C. High-Pressure Water Washing:

1. All surfaces to be painted shall be high-pressure water washed to remove dirt, loose or peeling paint, rust, excess chalk, efflorescence and contaminants that will affect adhesion of the prime or finish coats.

2. Pressure washing may not remove all contaminants or chalk. A close inspection of chalky surfaces shall be made to determine the need of more aggressive preparation by hand tools and priming

3. Areas that may introduce water into living areas such as entry doors, vents, and soffits shall be avoided.

4. Areas that are affected with mildew growth shall be washed using a commercial-grade cleaner or chlorine solution strong enough to neutralize the mildew. This is normally a 20% or 25% solution.

5. Comply with County or City environmental regulations requiring a special permit or prohibiting pressure washing.

6. Plan for the proper clean up and disposal of spent coatings removed by this process.

7. Allow all surfaces to dry thoroughly prior to preparation and painting.

D. Repair damage to substrate caused by preparation work.

E. Ensure that hardware is removed or protected before painting, and then replaced or uncovered when painting in that area is complete.

3.3 SURFACE PREPARATION

** NOTE TO SPECIFIER ** Delete substrate not required for Project.

A. Stucco/Plaster/Cement: Mechanically high-pressure water wash to remove dirt, dust, contaminants and loose and peeling paint from surfaces.

1. Patch large voids and cracks with Kelly-Moore Kel-Seal Elastomeric Sealant System.

2. Match existing stucco texture to blend in when surface is painted.

3. In the areas where the concrete is failing and causing the paint to peel, perform a pH test to assure acceptable pH level of 8 to 10 prior to coating.

B. Metal Preparation:

1. SSPC-SP 1, Chemical Cleaning: This includes commercial cleaner/de-greaser solutions, steam cleaning, alkaline cleaning or volatile solvent cleaning.

2. SSPC-SP 2, Hand Tool Cleaning: Sound coatings that are very hard or glossy shall be sanded to remove gloss and slightly roughen the surface. Prior to this, remove grease, salt, chemical dust, mildew or other contaminants.

3. SSPC-SP 3, Power Tool Cleaning: Care shall be taken to avoid polishing the surface or abrading too deeply.

4. SSPC - SP11, Power Tool Cleaning to Bare Metal: This requires complete removal of all visible grease, oil, dirt dust, mill scale, rust, paint, oxide, corrosion products and other foreign matter. A surface profile shall be maintained or produced to a degree suitable for the specified paint system.

C. Ferrous Metal - Mechanically high-pressure water wash metal where feasible to remove dirt, contaminants, rust scale or oxides and loose and peeling paint.
