Floor must be light blue or white with stain guard acrylic topcoat protective coating and must be formulated using anti-fungal agents and manufactured specifically for use in the commercial swimming environment. An acrylic stand guard coating must be a factory applied top coating designed to make cleaning easier and to minimize soiling. The material must be applied with the nonskid/textured side out in the floor area and on all gutter and step areas to provide slip resistance. All welds must be accomplished with hot air welding. Solvent welding of PVC materials is not permitted. Double stick mylar tapes are not permitted. Seams must be tacked, a continuous air entrapment weld must be performed continuous on all welds, and then a minimum 3/4" wide weld must be installed. Burning of the material is not permitted.

PART 3 EXECUTION

3.1 VERIFICATION OF CONDITIONS

The government will remove any water in the pool before work begins.

Before starting the work, verify surfaces that must be waterproofed are in satisfactory condition. Notify the Contracting Officer of defects or conditions anticipated to prevent a satisfactory application. Do not start application until defects and conditions have been corrected.

3.2 SURFACE PREPARATION

Ensure surfaces to receive treatment are clean, dry, smooth, and free from deleterious materials and projections. Cut off high spots or grind smooth. Finish top surfaces of projecting masonry or concrete ledges below grade, except footings, to a steep bevel with Portland cement mortar. Thouroughly clean surfaces to receive covering before applying pool liner system to remove dust and foreign matter. Cure concrete by a method compatible with the waterproofing system. All working cracks, expansion joints, or voids must be isolated from the 10.5 ounce felt layer above by the installation of rigid stainless steel strips.

SECTION 07 13 53 Page 4 REVISED 9 FEB 21

3.3 APPLICATION

3.3.1 General Installation Requirements

Install pool liner system in accordance with manufacturer's printed installation instructions. Ensure the surface to receive membrane is clean, smooth and dry without surface irregularities; correct deficiencies prior to installation. Avoid wrinkles and buckles in applying membrane and joint reinforcement.

3.3.2 Pool Liner Membrane (PVC)

Consult with membrane manufacturer prior to grid application. Install 12 inches wide sub-membrane containment grid as required by manufacturer.

Provide the containment grid at intervals across the width and length of the substrate, at the base of all transitions, walls, penetrations, and at the perimeter of each substrate section. Fully adhere strips to the concrete in a full bedding of manufacturer approved adhesive. Weld adjacent sheets in accordance with manufacturer's instructions. Hot-air weld all side and end joints.

3.4 FIELD QUALITY CONTROL

Notify the Contracting Officer 5 working days prior to date of performing tests. Fill pool after pool liner system has been installed. Coordinate with the Contracting Officer for water source. Test pool liner system for 24 hours. Do not add water after start of 24 hour period. Accurately measure water level at beginning and end of 24 hour period. If water level falls, remove water and inspect pool liner system. Make repairs or replacement as directed, and repeat test. Do not proceed with work that conceals membrane waterproofing before receiving approval and acceptance of the Contracting Officer.
