3. Apply a complete parge coat of the specified filler/surfacer material over the entire substrate before applying the coating system.
a. Scrub filler/surfacer into the substrate to completely fill open air voids and bug holes.
b. Completely cover the substrate, unless otherwise specified, above such filled voids by 1/8 inch of thickness.
c. Provide relatively flat, uniformly even surface before coating application.

4. Secondary containment: Place surfacer or filler 1/16 inch thick above concrete plane to create a monolithic surface free of pinholes.
a. Floor surfaces: Broadcast with aggregate to create a non-slip surface texture.
b. Remove excess aggregates and apply base coat to encapsulate embedded non-slip aggregate.

C. Concrete substrate temperatures:

1. Apply filler/surfacers and the coating system when temperatures are falling, typically late afternoon or evening.
a. Do not coat concrete with rising concrete substrate surface temperatures or substrates in direct sunlight, to minimize outgassing from the substrate and formation of pinholes, and/or blistering.

2. Should bubbles, pinholes, or other discontinuities form in the applied coating system material, they shall be repaired.
a. Should discontinuities develop in the filler/surfacer material or in the first coat of the coating material, repair them before the next coat. b. When discontinuities occur, open the air void behind or beneath the discontinuities and completely fill with specified coating material. Then, abrade the coated area around the discontinuities repair reapply coating over that area.

D. Perform application detail work in accordance with these Specifications, the CSM’s current written recommendations, and drawings, whichever is stricter.

E. Concrete coating systems application requirements:

1. Concrete coating minimum dry film thickness excludes parge coat, block filler, and sealer.

3.11 COATING SYSTEM SCHEDULE
A. Attachment A - Schedule of Surfaces to be Field Coated specifies surfaces to be coated in the field with the coating systems required.

3.12 SURFACES NOT REQUIRING COATING
A. Stainless steel piping, valves, pipe supports, instrument sunshades.

B. Sliding surfaces on expansion joints, motor and pump shafts, machined surfaces at bearings and seals, grease fittings, etc.

C. Galvanized structural steel framing, galvanized roof decking, galvanized pipe supports.
