Polyurethane containing any TDI (Toluene Diphenel Isocyanate) shall not be allowed due to environmental regulations.

C. Cushion Layer shall be a mixture of 3/8" shredded and a 1mm-3mm SBR rubber particles of heterogeneous distribution (50/50 mixture) bonded by a polyurethane binder applied to 100 percent of the rubber and installed to a designated thickness as required by the Consumer product Safety's Commission's Guidelines and ASTM F1292 Test Criteria. Thickness of Cushion layer varies according to CPSC Guideline depending on height of fall for tallest equipment.

1. Material: Blend of 100% recycled SBR (styrene butadiene rubber) and urethane.

2. Thickness: 3″ min (76 mm)

3. Formulation Components: Blend of strand and granular material.

3.02 INSTALLATION

A. Surface Preparation: Using a brush or short nap roller, apply primer to the substrate perimeter and any adjacent vertical barriers such as playground equipment support legs, curbs or slabs that will contact the surfacing system at the rate of 300 ft2/gal (7.5 m2/L).

B. Install Shredded SBR cushion course and EPDM wearing surface system per manufacturer’s instructions.

a. Over aggregate: Install play surfacing system over geotextile fabric over compacted aggregate substrate, slope to drain aggregate no less than 2 percent.

b. Basemat Installation:

1) Using screeds and hand trowels, install the basemat at a consistent density of 29 pounds, 1 ounce per cubic foot (466 kg/m3) to the specified thickness.

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

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

c. Top Surface Installation:

1) Using a hand trowel, install top surface at a consistent density of 58 pounds, 9 ounces per cubic foot (938 kg/m3) to a nominal thickness of 1/2″ (12.7 mm).

2) Allow top surface to cure for a minimum of 48 hours.

3) At the end of the minimum curing period, verify that the top surface is sufficiently dry and firm to allow foot traffic and use without damage to the surface.

4) Do not allow foot traffic or use of the surface until it is sufficiently cured.

C. Perimeter: As indicated on drawings and installed in accordance with Section 32 13 13:

1. Flush with Exposed Concrete Perimeter Curb: Top of concrete curb to flush with finished surface, tooled rounded edges.

D. Manufacturer shall have manufactured and installed playground poured-in-place surfacing systems to current ASTM F1292 Test Criteria for a minimum of 5 years. The installation of the poured-in-place product shall be completed by Manufacturer Certified Contractors or by direct employees of the Manufacturer's Installation Division.

Manufacturer's detailed installation procedures shall be submitted to the Architect.

E. Make necessary adjustments to system to accommodate playground equipment uprights installed into grade.

F. Install play surfacing level abutting Path of Travel and each playground equipment.
