SR Pro 7 Synthetic Rubber Base Pool Coating

SR PRO 7 is a synthetic rubber base swimming pool finish made with a styrene acrylic polymer resin. It is recommended for concrete or plaster pools and for pools previously coated with a rubber base coating. SR PRO 7 provides a hard, durable finish that protects against harsh chemicals, resists algae, and beautifies the pool surface.

SR PRO 7 is available in four stock colors.

SURFACE PREPARATION

Bare Concrete or Plaster

Two coats are required on bare surfaces. New concrete should cure 30 days before coating.

The surface must be clean before coating. First, scrub the entire surface with tri-sodium phosphate (TSP) solution in water. Mix one cup (8 oz.) dry TSP powder for each gallon of water as a washing solution. Rinse with water immediately. Then, the surface should be acid washed with a 10% solution of muriatic acid in water, or 2 lbs of sulfamic acid crystals with one gallon of water. One gallon of either solution will etch approximately 100 sq. ft. Rinse with water immediately. Then, repeat TSP wash to neutralize any remaining traces of acid. Allow surface to dry completely.

Previously Coated Surfaces

SR PRO 7 should only be applied over worn rubber base coatings. Do not apply over epoxy or unknown coatings.

All loose or peeling coating should be scraped or wire brushed. If coating is severely peeling, sandblast or water blast to remove all old coating.

Scrub entire surface with tri-sodium phosphate (TSP) solution in water. Mix one cup (8 oz.) dry TSP to each gallon of water for a washing solution. Rinse thoroughly with water. Then, the surface should be acid washed with a 10% solution of muriatic acid in water, or 2 lbs of sulfamic acid crystals with one gallon of water. One gallon of either solution will etch approximately 100 sq. ft. Rinse with water immediately. Then, repeat TSP wash to neutralize any remaining traces of acid. Allow surface to dry completely.

APPLICATION

Uncoated Surfaces

First Coat
Apply first coat of SR PRO 7 thinned with #1108 Rubber Base Solvent as a prime coat. Thin about 10 to 20% to insure penetration. Do not thin with any other substance. Thinning with other than #1108 Rubber Base Solvent will cause failure. Use a 9” roller and an extension handle for large areas. Trim small areas with a brush.

Second Coat
Apply the second full strength after four-hour minimum drying time.

Previously Coated Surfaces
Bare spots should be spot primed with SR PRO 7 thinned 10 - 20% with #1108 Rubber Base Solvent. After spot priming, apply one or two coats as needed at full strength. Allow four hours minimum between coats.

DO NOT APPLY BELOW 50°F
