PART 3 EXECUTION

3.01 SUBSTRATE EXAMINATION

1. Examine substrates scheduled to receive coating system for conditions that may adversely affect the work. Do not apply specified coating systems until conditions are satisfactory.
2. Verify the following:

1. Retaining walls, planter walls, steps, and similar construction elements have received waterproofing systems on backside of surfaces prior to backfilling.
2. Compatibility of joint sealants in surfaces to receive traffic coating system.

3.02 SURFACE PREPARATION

1. General: Perform surface preparation, including cleaning procedures, pursuant to coating manufacturer's published instructions and as specified for each particular substrate and coating condition.

1. All surfaces must be sound and clean prior to coating system application. Remove dust, dirt, mildew, incompatible release agents, form oils, floor hardeners, loose substrate material, and similar surface contaminants.
2. Completely remove existing painted surfaces exhibiting loose, flaking, or oxidized paint. Use sandblasting, waterblasting, electric sanding, or wire brushing for paint removal, and pursuant to coating manufacturer's published instructions.
