PART 3 - EXECUTION

0.1 EXAMINATION

A. Examine substrates, areas, and conditions, with the Applicator present, under which resinous floor coating will be performed for compliance with resinous floor coating application requirements. 1. Do not begin to apply resinous floor coating until unsatisfactory conditions have been corrected and surfaces receiving resinous floor coating are thoroughly dry. 2. Start of resinous floor coating will be construed as the Applicator's acceptance of surfaces and conditions within a particular area.

0.2 PREPARATION

A. Cleaning: Before applying resinous floor coating or other surface treatments, clean the substrates of substances that could impair the bond of the various coatings. Remove oil and grease before cleaning. Schedule cleaning and resinous floor coating so dust and other contaminants from the cleaning process will not fall on wet, newly coated surfaces.

B. Surface Preparation: Clean and prepare surfaces to be coated according to manufacturer's written instructions for each particular substrate condition and as specified. 1. Provide barrier coats over incompatible primers or remove and reprime. 2. Concrete: Remove glaze, chalk, dust, dirt, grease, oils, and release agents. If curing compounds, hardeners or sealers have been used to improve curing, use mechanical methods of surface preparation. a. Shot-blast surfaces with an apparatus that abrades the concrete surface, contains the dispensed shot within the apparatus, and recirculates the shot by vacuum pickup. b. Surface texture shall be similar to 100 grit sandpaper. c. Determine alkalinity and moisture content of surfaces by performing appropriate tests. If surfaces are sufficiently alkaline to cause the finish resinous floor coating to blister and burn, correct this condition before application. Do not coat surfaces where moisture content exceeds that permitted in manufacturer's written instructions.

3. Ferrous Metals: Clean ungalvanized ferrous-metal surfaces that have not been shop coated; remove oil, grease, dirt, loose mill scale, and other foreign substances. Use solvent or mechanical cleaning methods that comply with the Steel Structures Painting Council's (SSPC) recommendations. a. Touch up bare areas and shop-applied prime coats that have been damaged. Wire-brush, clean with solvents recommended by resinous floor coating manufacturer, and touch up with the same primer as the shop coat.

C. Materials Preparation: Mix and prepare resinous floor coating materials according to manufacturer's written instructions. 1. Maintain containers used in mixing and applying resinous floor coating in a clean condition, free of foreign materials and residue. 2. Stir material before application to produce a mixture of uniform density. Stir as required during application. Do not stir surface film into material. If necessary, remove surface film and strain material before using. 3. Use only thinners approved by resinous floor coating manufacturer and only within recommended limits.

D. Use patching and fill material to fill holes and depressions in substrates according to manufacturer's written instructions.

E. Treat control joints and other nonmoving substrate cracks to prevent cracks from reflecting through resinous flooring according to manufacturer's written recommendations.

0.3 APPLICATION

A. General: Apply resinous floor coating according to manufacturer's written instructions. Use applicators and techniques best suited for substrate and type of material being applied. 1. Resinous floor coating colors, surface treatments, and finishes are indicated in the schedules. 2. Do not coat over dirt, rust, scale, grease, moisture, scuffed surfaces, or conditions detrimental to formation of a durable resinous floor coating film. 3. Provide finish coats that are compatible with primers used.

B. Application Procedures: Apply resinous floor coatings by brush, roller, spray, or other applicators according to manufacturer's written instructions. 1. Brushes: Use brushes best suited for the type of material applied. Use brush of appropriate size for the surface or item being coated. 2. Rollers: Use rollers of carpet, velvet back, or high-pile sheep's wool as recommended by the manufacturer for the material and texture required. 3. Spray Equipment: Use airless spray equipment with orifice size as recommended by the manufacturer for the material and texture required. Spray application to be used only with the approval of the Owner.

C. Minimum Thickness: Apply resinous floor coating materials no thinner than manufacturer's recommended spreading rate. Provide the total dry film thickness of the entire system as recommended by the manufacturer.

D. Prime Coats: Before applying finish coats, apply a prime coat of material, as recommended by the manufacturer, to material that is required to be coated or finished and that has not been prime coated by others. Recoat primed and sealed surfaces where evidence of suction spots or unsealed areas in first coat appears, to ensure a finish coat with no burn through or other defects due to insufficient sealing.

E. Finishes: Completely cover surfaces as necessary to provide a smooth, opaque surface of uniform finish, color, appearance, and coverage. Cloudiness, spotting, holidays, laps, brush marks, runs, sags, ropiness, or other surface imperfections will not be acceptable.

F. Completed Work: Match approved samples for color, texture, and coverage. Remove, refinish, or recoat work not complying with requirements.

0.4 PROTECTION AND CLEANING

A. Protect adjacent surfaces from over spray or splattering. Correct damage by cleaning, repairing or replacing, and recoating, as approved by Owner’s Representative.

B. Provide "Wet Paint" signs to protect newly coated finishes. Remove temporary protective wrappings provided by others to protect their work after completing coating operations.

C. Cleanup: At the end of each workday, remove empty cans, rags, rubbish, and other discarded resinous floor coating materials from the site. 1. After completing coating, clean resinous floor coating-spattered surfaces. Remove spattered resinous floor coating by washing and scraping. Be careful not to scratch or damage adjacent finished surfaces.
