While the finish is still "green," the Contractor shall cut or tool a clean, continuous line into the finish along the entire perimeter floor-to-wall intersection. Once cured, this joint shall be filled with a flexible, color-matched submersible sealant.

5) Joint Sealants: The specific product used to seal joints and seams directly adjacent to the PebbleTec finish is Sikasil® Pool (or approved equivalent), which is a high-performance, neutral curing silicone-based sealant designed specifically for constant underwater immersion and chlorine resistance. For any other submerged structural concrete joint sealants not directly in contact with the plaster, the Contractor shall utilize a multi-part, chemical-curing polysulfide-based sealant (such as Sika® Duoflex or equivalent). Polyurethane-based sealants are not permitted in any submerged pool shell areas.

6) Submittals: The Contractor shall submit detailed shop drawings for all three joint treatment details, including plaster stop specifications and sealant product data sheets, to the Contracting Officer for approval prior to the start of pool shell preparation. Failures in the finish related to improper joint treatment shall be fully covered under the Contractor's warranty.

o. Labor shall include:

1) Installing a new exposed aggregate pool liner after completion of the overflow gutter system and all penetration repairs, providing a fully bonded, uniform, commercial grade finish; preparing the pool shell and repairing all substrate defects prior to application; applying the aggregate finish consistently across all surfaces; ensuring proper bonding, curing, and uninterrupted filling of the pool; delivering a smooth, slip resistant, visually uniform final surface; ensuring the finish performs reliably under normal pool chemical and environmental conditions; and providing a warranty covering workmanship, adhesion, finish quality, and material performance.

CLIN-4 - All measurements should be contractor field verified for accuracy.

The contractor shall price both CLIN-3 and CLIN-4. The Government will decide which pool finish (CLIN-03 Exposed Aggregate Finish or CLIN-04 Epoxy Pool Coating) will be awarded.

Application of High-Performance Epoxy Pool Coating System

a. General Requirements

1) In lieu of the exposed aggregate (PebbleTec) finish, the Contractor shall furnish and apply a heavy-duty, two-part, polyamide-cured epoxy pool coating system designed specifically for commercial swimming pools and continuous underwater immersion.

2) Basis of Design: Ramuc Type EP Epoxy, Kelley Technical Coatings, or approved equal.

3) The coating must be chemically inert, non-toxic when fully cured, and safe for bather contact in accordance with public health and safety standards.

4) The coating system must be compatible with chlorine and standard pool shock treatments, offering high resistance to UV degradation, fading, and chalking.

b. Substrate Preparation (Critical):

1) The Contractor shall completely remove all existing, deteriorated paint down to the bare concrete substrate.

2) The bare concrete shall be mechanically prepared (e.g., abrasive blasting or high-pressure water jetting) to achieve a uniform Concrete Surface Profile (CSP) of 3 to 4, as defined by the International Concrete Repair Institute (ICRI), to ensure optimal mechanical adhesion.

3) Following profiling, the surface shall be acid-etched and neutralized using a manufacturer-approved heavy-duty cleaner/degreaser and a neutralizing rinse (e.g., Tri-Sodium Phosphate). The surface must be completely dry before application.

c. Application Performance:

1) The coating system shall consist of a minimum of one (1) prime coat and two (2) finish coats.

2) The coating shall be applied strictly in accordance with the manufacturer's specified Wet Film Thickness

(WFT) and Dry Film Thickness (DFT) requirements.

3) Slip Resistance: The Contractor shall incorporate a manufacturer-approved slip-resistant additive (e.g., synthetic aggregate or silica sand) into the final coat on all stairs, ramps, wading areas, and any surfaces shallower than 3 feet. The finished surface must meet or exceed ADA and OSHA slip-resistance requirements for wet commercial pool environments without being abrasive to bare feet.

4) Lane Lines: The Contractor shall apply eight (8) high-contrast swimlane identifier markings and depth markers aligned with existing lane geometry. Lane markings must be applied using a compatible, contrasting epoxy color and must integrate seamlessly with the base coating.

d. Curing & Testing:

1) The pool shall not be filled with water until the coating system has cured for the absolute minimum duration specified by the manufacturer (typically 5 to 7 days, depending on ambient temperature and humidity).

2) Upon completion, the Contractor shall warrant the epoxy coating system against peeling, blistering, and delamination for a minimum of two (2) years.
