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.
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.
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.
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.

CAUTION! - COMBUSTIBLE!
Keep away from heat and open flame. Avoid prolonged contact with skin and breathing of vapor. Close container after each use. Areas
of body or clothing on contact with uncured resin and/or catalyst should be thoroughly cleaned with solvent and washed with soap and
water immediately. Use only where there is adequate ventilation.
