2. Prefabricated rubber surface to be sheet goods, calandered and vulcanized with a particular closed cell structure, based on special isoprenic rubbers, mineral fillers, vulcanizing and stabilizing agents and color pigments, highly resistant to UV rays and atmospherical agents, with system of differentiated elasticity between top surface and base, supplied in rolls of suitable size and thickness.

3. Prefabricated rubber sport surface to be manufactured in two layers, which are vulcanized together. The shore hardness of the lower layer to be less than the upper layer, shore hardness of the respected layers to be recommended by the manufacturer and within the limits hereinafter specified. Field laminated triple durometer are unacceptable.

4. Physical properties of the prefabricated sport surface to conform to the requirements found in the following table:

Manufacturer reserves the right to change, at any time without notice, the physical properties or specifications to improve the products or production process.

2.2 Adhesive

Rubber sport surface adhesive to be two part polyurethane adhesive suitable for adherence of a rubber sport flooring to asphalt, concrete or urethane substrate. Adhesive to be supplied or approved/recommended by rubber sport flooring manufacturer.

2.3 Patching compound

Patching compound to be supplied or approved/recommended by rubber sport flooring manufacturer.

2.4 Line marking

Line marking paint to be supplied by rubber sport flooring manufacturer.

PART 3 EXECUTION

3.1 Inspection
