PARALON 2 and EXCELLON Chlorinated Rubber Pool Coatings

Kelley Technical Coatings manufactures two types of chlorinated rubber base pool coating.

PARALON 2 is our standard grade rubber base coating which should yield one or two years of service under normal conditions. This coating has a low sheen, eggshell type finish and is compatible with other chlorinated rubber pool coatings.

EXCELLON is our premium grade rubber base enamel which exhibits a high gloss finish and should yield about three years of service.

The working properties and application instructions are identical for the two rubber base coatings; therefore, the following technical information applies to both PARALON 2 and EXCELLON.

SURFACE PREPARATION FOR PREVIOUSLY COATED POOLS

It should first be determined what type of coating is presently on the swimming pool. PARALON 2 and EXCELLON should only be applied over chlorinated rubber pool coating. If the type of old coating is not known, send a sample chip to us for analysis.

All loose and peeling coating must be removed with a wire brush and scraper. If more than 10% of the pool surface is peeling, then the entire surface should be sandblasted or water blasted for complete coating removal.

Once the pool has been scraped, it must be washed with our #910 Pool Washing Compound or a tri-sodium phosphate (TSP) solution to remove oily substances such as body oils, suntan lotion and other residue. Mix one cup TSP to each gallon of warm water. Using a long handled, stiff bristled brush, firmly scrub down the walls and floor of the pool with the TSP solution. Follow by thoroughly rinsing the pool with clean water.

Any bare spots should be acid etched as outlined in Bulletin #141 and "spot primed" with chlorinated rubber base coating.

New concrete or plaster must cure for at least 30 days before the application of chlorinated rubber base coatings. Then the surface must be acid etched as outlined in Bulletin #141. Neutralize and remove all traces of acid with #910 Pool Washing Compound (TSP). Follow by thoroughly rinsing with clean water.

It is imperative that the pool be thoroughly dry before application of rubber base coating. Any moisture trapped under the coating film will result in blistering as the vapors try to escape. Any standing moisture should be mopped up and hand dried with rags or towels.

Once the pool is thoroughly clean and dry, you may begin coating. On uncoated pools, we recommend three coats for maximum performance. The first coat should be thinned 25% with #1108 Solvent to facilitate penetration of the coating into the concrete or plaster. The second and third coat should be applied full strength after at least four hours'''''''' drying time.

Do not apply coatings on cold walls when the nights go below 40 F (4.4¢ª C) and when the high temperature during the day is less than 50¢ª F (10¢ª C).

The best tool for coating small pools is a 9" roller equipped with a 3/8" nap and a solvent resistant core. Using an extension handle will speed up the job.

PHYSICAL DATA

Flash Point: PARALON 2, EXCELLON and #1108 Solvent - Over 105¢ª F

Pot Life (after opening): Indefinitely - if resealed tightly

Recoating time: 4 hours except in cool or damp weather, then allow overnight drying time. The first coat of coating must be absolutely dry. If moisture is present, wait until sun dries the moisture from the underlying or prime coat, or dry off with rags.

PARALON 2 and EXCELLON: Curing schedule before filling pool: Minimum of 5 days

NOTE!:

Coatings manufactured using a chlorinated rubber resin are usually dry to touch in 2 hours-75¢ª F to 95¢ª F. The longer they cure up to 14 days, the greater their resistance to water and pool chemicals. Do not fill the pool sooner than the above schedule.

Waiting time for new concrete or new plaster to "cure":

30 days - minimum for maximum results

SQUARE FEET PER GALLON:

1st coat - thinned 25% - 250 sq. ft. per gal. average

2nd coat - do not thin - 250 sq. ft. per gal. average

3rd coat or Recoating - do not thin - 275 sq. ft. per gal. average

APPLIED FILM THICKNESS:

3 to 4 mils (100762 to .01016 centimeter)
(Use wet film gauge)

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. KEEP OUT OF THE REACH OF CHILDREN.
