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.

Physical Properties:

Tensile Strength (ASTM D412) 60 PSI, minimum
Elongation at Break (ASTM D412) 140%, minimum
Flammability (ASTM D2859) Pass
Coefficient of Friction (ASTM D204)
Wet 0.9, minimum
Dry 1.0, minimum
Water Permeability 0.4 gal. /sq. yd./sec., minimum

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.

No. 200 2-9

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.

PART 5 - INSTALLATION:

Weather Conditions. - Because the polyurethane agents are moisture or heat sensitive, the
nighttime temperatures must be above 40 degrees with daytime temperatures around 50
degrees. These temperatures must be consistent for several days before and after the poured
rubber installation period. Complying with these weather conditions will prevent poured rubber

from freezing which prevents proper curing.

Thickness - Overall depth of the poured rubber will vary based on critical fall heights and
installers test results. Depth of EPDM/TPV will be no less than 0.5”. Installation is performed
by technically trained GameTime approved specialists. Your GameTime dealer will schedule
installation of playground surfacing to meet your requirements.

THICKNESS CHART _ - (Below depths include 0.5” EPDM/TPV Topcoat)

1' to 4' Critical Fall Height 1.5” to 2” Total Depth
5' Critical Fall Height 2” to 2.5” Total Depth
6' Critical Fall Height 2.5” to 3” Total Depth
7' to 8' Critical Fall Height 3” to 3.5" Total Depth
9' to 10' Critical Fall Height 4” to 4.5” Total Depth
11' to 12' Critical Fall Height 5.5” Total Depth

Cold Joints - Areas in excess of 2,000 square feet or areas that require adjacent color pours will
have a cold joint or seam. Although seldom visible, seams are necessary when large pads require

more than one day pours.

Edges - Surface edges shall be flush, beveled or rolled. It is important to advise what type of edge
will be required so that the appropriate amount of materials are ordered.

Flush_- When curbing is provided around the outside perimeters of the pad, the poured rubber
will be adhered to the edge of the curbing so that the rubber surfacing is flush. This allows for a
smooth transition into the play area. However, the sub-base should be installed to allow the
proper depth of poured rubber so that the flush edge can be installed without having to fill voids
by increasing the depth SBR materials. If the sub-base is not installed properly, using too much
of the SBR materials can cause the installer to run short on the cushion course which is require

a change order to add additional materials for the project.

Beveled - When curbing is not provided for concrete or asphalt sub-bases, the installers will
bevel the edge down along the edge of the pad. This type of edge can be sloped to provide a
smoother transition but will require additional materials. If beveled at the edge of the use zones,
the edge can be more round due to the depth of the poured rubber. In this case, you may want
to have a rolled edge added to allow a smooth transition for wheelchair users.

Gamehme;

PART 5 - INSTALLATION (Continued)

ADA Rolled - This is the type of edge to meet the requirements of ASTM 1951, Specifications
for Determination of Accessibility of Surface Systems Under and Around Playground Equipment.
The rolled edge will require additional materials in order to provide adequate ADA Wheelchair
access. The total linear feet of the pad will need to be provided if the whole site is to be ADA
compliant.

Keyway Cut - This type of an edge requires a trenched saw cut of 12” wide x %” deep along the
edge of the concrete or asphalt pad. The contractor or customer will be responsible for providing
the keyway cut. There will be a up charge if the poured rubber installer is asked to provide this
cut. The poured rubber will be beveled down into the saw cut where it will adhere preventing the

exposure of a raw edge.

Cure Time - The poured rubber will require 72 hours (3 days) to properly cure. Security is required
by the owner during this time so to avoid unnecessary damages.

PART 6 - WARRANTY:

When used under playground equipment, GameTime's GT Impax recycled poured rubber is
warranted against defects in materials and workmanship for five years.

When used with water play equipment, GameTime's GT Impax recycled poured rubber is warranted
against defects in materials and workmanship for three years provided aliphatic binder is added.
Without the aliphatic binder, the GT Impax recycled poured rubber will carry only one year warranty.
