1.04 SYSTEM DESCRIPTION
*****************************************************************
Choices regarding number of coats of resurfacer and color finish should be made based
on the following general principles;
- New Construction or overlays- will probably require two coats of acrylic resurfacer
- Reseals of existing surfaces- will generally only require one coat of acrylic
resurfacer.
A minimum of two slurry color coats are recommended. Very heavy play surfaces should
have a third application. To adjust speed of play on tennis courts a third coat without
aggregate will result in a slightly faster and less abrasive surface.
*****************************************************************
A. Provide [ [ one (1) ] [ two (2) ] [ three (3) ] ] coat [ s ] of Acrylic Resurfacer
over prepared surface.
B. Provide [ [ two (2) ] [ three (2) ] [ four (4) ] ] coats of Acrylic Color Slurry
Coating over prepared surface after Acrylic Resurfacer has dried thoroughly.
C. Place lines on surface in accordance with USTA requirements.
*****************************************************************
Colors available include green, dark green, red, beige, gray, and blue. Custom color
matching is also available from Neyra Industries, Inc. Greens are coolest and easy on the
eyes. Blue is primarily intended for indoor courts where reflective color may be
desirable.
*****************************************************************
D. Colors selected are to be [ ] inside play lines and [ ] in the perimeter area

2.03 MIXES
A. Color Coating Slurry Mixes: Per one hundred (100) gallons of color concentrate, add
forty (40) to fifty (50) gallons of water, then add and mix from four (4) to eight (8)
pounds per gallon of silica sand as per manufacturer’s written specification. (If
Center Court is used, no additional sand is required.)
B. Acrylic Resurfacer: Per one hundred (100) gallons of concentrate add forty-five (45)
to fifty-five (55) gallons of water. Then add and mix six (6) to twelve (12) pounds of
silica sand as per manufacturer’s recommendation.
2.04 EQUIPMENT
A. All equipment, tools, and machinery used for handling materials and executing work
shall be in good working condition and capable of applying required coating weights evenly
to provide a smooth uniform coated surface.
PART 3 EXECUTION
3.01 EXAMINATION
A. Inspect existing pavement surfaces for condition and defect that will adversely
affect quality of work, and which cannot be put into an acceptable condition through
normal preparatory work as specified. Do not place coating if defects exist, notify
Architect/Engineer.
B. Starting installation constitutes contractor’s acceptance of surface as
suitable for installation.
*****************************************************************
SPECIFIER SHOULD SELECT SECTION UNDER PREPARATION BASED ON JOB REQUIREMENTS.
*****************************************************************
3.02 PREPARATION - EXISTING ASPHALT TENNIS COURT
[ A. Overlay courts according to requirements detailed in Section 02965. ]
[ B. Repair courts as detailed in Section 02950 of this specification. ]
*****************************************************************
OR
*****************************************************************
A. Repair grade depressions: Prior to the application of coating materials, entire
surface should be checked for minor depressions or irregularities. This is to be done by
flooding the courts and after one-half (1/2) hour marking any depres-sions where water
covers a nickel one eighth (1/8) inch. Fill such irregularities with court patch binder
according to manufacturer’s specifications.
B. Clean all cracks thoroughly and fill.
1. Cracks less than one-quarter (1/4) inch in width shall be filled with acrylic crack
sealant.
2. Cracks greater than one-quarter (1/4) inch in width shall be filled with court patch
binder.
C. Cleaning
1. Thoroughly clean surfaces to be coated to remove all foreign debris (dirt, silt,
gravel, leaves, etc.) using mechanically powered forced air sweepers, mechanical street
sweepers, steel bristle brooms and/or high pressure water.
2. Thoroughly scrape mud areas and scrub wash with clean water.
3. If fungus is present, use a two (2) percent sodium hypochlorite solution to clean
affected area. Rinse thoroughly.
D. Protection: Protect adjacent curbs, walks, fences, and other items from receiving
color coat or resurfacer.
3.03 NEW ASPHALT TENNIS COURTS
A. Cleaning
1. Thoroughly clean surfaces to be coated. Remove all foreign debris (dirt, silt,
gravel, leaves, etc.) using mechanically powered forced air sweepers, mechanical street
sweepers, steel bristle brooms and/or high pressure water.
2. Thoroughly scrape mud areas and scrub wash with clean water.
B. Protection: Protect adjacent curbs, walks, fences, and other items from receiving
color coat or resurfacer.
C. New pavements which have been accepted by Architect/Owner, shall be allowed to cure,
and pass the "no water break" test before application. Cast one or two gallons
of clean water from a suitable clean container (such as a 5 gallon pail) out on the
surface. The water should sheet out and wet the surface uniformly without ribboning,
crawling, or showing oil rings. (Comparable to water on very clean glass vs. dirty or
greasy glass.) If the clean water does not wet the surface uniformly, the asphalt is not
ready for coating and should age longer.
3.04 APPLICATION
A. When making mixes add water first then while agitating add silica sand slowly. Keep
mixture homogeneous prior to beginning application and during entire time mixture is being
applied.
B. Apply acrylic resurfacer uniformly over entire pavement per manufacturer’s
specifications.
C. Allow adequate time between applications for prior coat to dry thoroughly before
applying next coat. Acrylic resurfacer can normally be re-coated after four (4) hours of
good drying with sun. Color coats can normally be re-coated after two - four (2 - 4) hours
of good drying with sun. Upon completion of final coat keep all foot traffic off sealed
surface. Allow the final coat to cure at least twenty-four (24) hours, under good drying
conditions, before allowing foot traffic on surface. Less favorable conditions will
require longer drying times.
D. Finished surface shall be free of streaks, pinholes, or uneven distribution of sand
and shall have a uniform appearance.
E. Playing lines: Base lines shall be [ [ two (2) inches ] [ three (3) inches ] [ four
(4) inches ] ] (be sure to state width of base lines) wide and playing lines not more than
two (2) inches wide, accurately located and marked in accordance with rules of the United
States Tennis Association, and painted with a paint recommended or approved by the
manufacturer of the color finish material; however, use of traffic, oil, alkyd, or
solvent-vehicle type paint is prohibited.
The painting shall be done by skilled mechanics in a workmanlike manner in accordance
with the manufacturer’s standard printed instructions. Prior to white line paint
application, line paint tape gap filler shall be applied to reduce incidence of fuzzy
lines.
3.05 PROTECTION
A. Barricade coated areas until coating has dried sufficiently for foot traffic.
