3.04 APPLICATION OF PLAYING SURFACE
A. Apply one (1) coat of WB100 water based epoxy using a 3/8” floor roller or neoprene rubber squeegee. WB100 is a two part epoxy that will be mixed with an electric drill and Jiffy blade for three minutes. Once mixed the pot life is forty five minutes. Applications will be done in sections. Broadcast 10lbs 50-mesh silica sand per gallon of WB100 on the wet epoxy. WB100 Application rate is 0.045 gallons per square yard. Allow WB100 to dry completely. Broom, blow or vacuum any loose silica sand. Next application must be applied within seventy two hours.
B. (OPTIONAL) Using a neoprene rubber squeegee, apply one (1) coat of Novasurface acrylic resurfacer, diluted one (1) part water to two (2) parts Novasurface. Clean bagged 50-mesh silica sand shall be incorporated into the diluted Novasurface at the rate of five (5) to ten (10) lbs. per gallon. Allow to dry completely before next application. Novasurface concentrated application rate is 0.156 gallons per square yards.
C. Inspect the entire surface, any defects should be repaired. Scrape the surface to remove any lumps. Blow and broom off any loose matter.
D. Using a neoprene rubber squeegee apply two (2) coats of Novacrylic Combination surface, diluted two (2) parts concentrated material to one (1) part clean water (colors to be determined by owner). Combination Surface concentrated application rate is 0.055 gallons per square yard. Allow each application to dry completely before next application. The quantity of water used in diluting these coatings may exceed the quantity specified by only a small amount and only if coatings are drying too rapidly. Permission of owner shall be obtained before adding additional water.
3.05 APPLICATION OF LINE MARKINGS
A. Lines shall be carefully measured and marked with chalk in accordance with USTA Rules of Tennis and ASBA Tennis Book Guidelines.
B. All lines are to be applied by painting between painter’s grade masking tape with a brush or roller. No spraying of lines allowed.
C. Prime masked lined with one (1) coat Seal-A-Line. Allow Seal-A-Line to dry completely before next application. Application rate is 0.08 gallons per square yards or 1 gallon per tennis court.
D. Paint lines with Novatex textured line paint.
Application rate is 0.08 gallons per square yards or 1 gallon per tennis court.
Allow application to dry.
E. Remove masking tape immediately after Novatex is dry. Do not leave the masking tape on overnight.
A. Allow a minimum of 24 hours drying time for outdoor courts before opening for play. Indoor courts will take longer to dry and cure and should dry a minimum of 7 days before play is allowed depending on the atmospheric conditions in the building.
3.07 CLEAN UP
A. All containers and debris shall be removed and disposed of in accordance with local, state and Federal regulations.
