Surface Preparation: Using a brush or short nap roller, aoply primer to the substrate
perimeter and any adjacent vertical barriers (such as playground equipment) at the rate
of 300 ft2/gal.

INSTALLATION

Do not proceed with playground surfacing installation until all applicable site work,
including substrate preparation, fencing, playground equipment installation and other
relevant work, has been completed.

Base Layer Installation:

1. Using screeds and hand trowels, install the base layer at a consistent density of
29 pounds, 1 ounce per cubic foot to the specified thickness.

2. Allow base layer to cure for sufficient time so that indentations are not left in the
base layer from applicator foot traffic or equipment.

3. Do not allow foot traffic or use of the base layer surface until it is sufficiently
cured.

Product Specification

PART 1 - GENERAL

Work Details:

This work includes furnishing and installing GT Impax recycled poured rubber surfacing.

GT Impax recycled poured rubber surfacing shall be poured in place and trowelled to
provide for a resilient, seamless rubber surface installed over the specified base. The
surfacing provider shall be responsible for all labor, materials, tools, equipment, and
applicable taxes to perform all work and services for the installation of the surface. The
surface shall be stable and slip resistant to comply with all requirements set forth in the
Americans with Disabilities Act.

Quality Assurance & Compliance Details:

Impact Attenuation - ASTM F1292-04: |mpact attenuation test results will be provided to the
owner or owner's representative. These test results shall be certified and submitted on the
letterhead of an independent testing lab. Impact attenuation test results shall meet or
exceed Consumer Product Safety Commission Guidelines for impact attenuation (G-max and

Head Injury Criteria (HIC).

Accessibility of Surface Systems - ASTM F1951-08: All Playground surfacing products must
pass testing to ensure wheelchair access under and around playground equipment as
required by the American Disabilities Act.

Coefficient of Friction - ASTM D2047-82: All products must meet a minimum standard on
coefficient of friction of .9-wet, 1.0 dry.

Permeability. Product shall meet or exceed a coefficient of permeability of 0.4 gallons per
square yard per second.

Flammability of Finished Floor cover - ASTM D2859: Product shall meet requirements of
ASTM D2859.

products, their thickness and critical heights may be viewed at www.ipema.org.”

Submittal Details:

Submittal packages shall include but not be limited to: (1) product samples, (2) supplier's
written warranty, and (3) independent laboratory results.

PART 2 - MATERIAL DATA:

Polyurethane Primer and Binder - 100% Single Component Polyurethane Binding Agent -
Methylene Dephenyl Isocyanate (MDI) based binder.

Aromatic Binder - All projects will include aromatic binder unless project specifies the use
of aliphatic binder. The natural properties of the aromatic binder is to present a yellow tint
which may cause some EPDM/TPV colors to amber. The yellowing affect is more common
on lighter EPDM colors and will wear off with foot traffic and weathering.

Aliphatic Binder - This binder is available upon request but at an added cost to the over all
project. Aliphatic binder is all clear providing full EPDM/TPV color from day one. This
binder has a higher resistance to ultra violet light and provides a greater resistance to wear.

Impact Course - The impact layer is to be a precise combination of 100% recycled black
Styrene Budadine Rubber (SBR) and polyurethane binder. SBR is manufactured as a liquid,
poured into molds and generally used by the automobile industry. This recycled rubber is
shredded, mixed with binder and hand-trowelled to create a seamless application. The impact
course thickness, as specified by owner or architect, must be composed of recycled rubber and

free of foreign matter.

Wear Course - The wear course is made of Ethyl Propolyne Dione Monomer (EPDM)
or Thermal Plastic Vulcanized (TPV) pigmented rubber granules with polyurethane binder.
Thickness of the wear course shall be a minimum 1/2".

EPDM- The granule size will be 1-3 mm in diameter.
TPV- The granule size will be 1-4 mm in diameter.

Colors - The color of GT Impax recycled poured rubber surfacing will be indicated on plans.
Owner or owner's representative will be responsible for selecting standard blends. Selection of
either standard color blends or custom color blends must be made at time quotation is being
requested. EPDM/TPV colors are available in 100% black and a variety of colors. Ask your
GameTime representative for available color combinations.

Note: If graphic designs and color transitions are used, they shall be full wear course depth.
Color(s) to be determined by architect. Graphic Templates are the responsibility of the
Architect or owner.

PART 3 - SUB-BASE TYPES & DETAILS:

Sub-base Requirements - The base shall have the specific maximum slope (2%) and shall vary
no more than 1/8” when measured in any direction with a 10° straight edge.

Stone - The density requirement is 90% to 95% compaction with final condition of stone as level
and stable so as not to shift when traveled on or during surface installation process. A
compaction test is required and must be submitted to GameTime prior to installation of poured
rubber surfacing. Failure to provide proof of compaction test will void 5-year warranty of PIP
surfacing should signs of sub-base failure occurs.

Depth: 4 inch minimum thickness.

Slope: Stone elevation shall maintain %” per foot toward low end.

Porosity: Base course shall maintain porosity for direct drainage.

Enclosure: Stone base course must be surrounded by a retaining curb.

Drainage: Subsurface drainage is recommended under and around a stone base.
Perforated pipe or similar system is acceptable.

Tolerances: VY," in any 10-foot direction and 1/8” in any 3-foot direction.

Stone Selection: It is critical that different size stones are used so that the base shall be

uniformly mixed. The material shall be wetted during mixing operations if
necessary for proper blending.

Concrete or Asphalt - Concrete should be finished with a medium broom finish. All new
concrete slabs must cure for a minimum of seven (7) days prior to installation. Asphalt cure
time requires fourteen (14) days. Once the new asphalt has cured, it must be pressure
washed prior to the surfacing being installed. The concrete contractor shall be responsible
for flooding the pad to insure proper slope and tolerance. Any areas holding enough

water to cover a flat nickel shall be patched prior to arrival of poured rubber installation crews.

Depth: 4 inch minimum thickness.
Slope: Concrete or asphalt shall maintain 4” per foot.

Tolerance: Concrete must maintain a tolerance of 1/8” in 10 ft. to avoid low areas that will
hold water under the poured rubber surfacing.

PART 4 - SITE PREPARATION AND REQUIREMENTS:

Drainage - Having proper drainage at the low end of the concrete slab is of utmost
importance. Any brick walls or curbs at the low end of the slab shall have drainage

access through weep holes. Concrete curbing weep holes should be level with finish

grade of sub-base or a minimum of 1/8" below top of concrete slab, as GT IMPAX

recycled poured rubber surfacing is porous and water drains immediately through it. Weep
holes shall be 2” high and 3" wide and shall be installed every three (3) feet. If weep

holes are smaller than the recommended size, they shall be installed every 18". Floor drains
shall be located outside the high impact areas, as the drains may not be covered with GT
IMPAX poured rubber surfacing. Recommended locations for drains are against low-end

wall or curb.

Security & Waste Disposal - Surface installation crew shall be responsible for the
protection of surface during the installation process while on site only. Owner

or general contractor shall be responsible for the protection of the surface during the curing
period upon completion of the installation and overnight during the installation. Owner

or general contractor shall be responsible for having a dumpster on site for all waste and
debris. Failure to provide security and a dumpster will result in additional cost.

Utilities & Access - Power and water must be available within 300 feet of installation. Site
will require tractor-trailer access. In a case where tractor-trailer access is not possible, owner
or general contractor shall be responsible for transporting materials from delivering carrier to
the installation site.
