Patent ID: 7600309

Claim:
A method of surfacing the inner surfaces of a gunite swimming pool shell, comprising the steps of: providing a gunite swimming pool shell prepared to receive a surface treatment; mixing, for approximately 5-7 minutes, a combination of cement and 1/16-¼ inch marble aggregate, in a ratio of about 1 to 1-2 parts respectively, and swimming pool sand at about ¼ part with sufficient potable water to create a smooth textured mixture; adding a plasticizer to said mixture; pumping said mixture to said gunite shell; applying said mixture from said pump to said gunite shell; trowelling said mixture onto said gunite shell to form a still soft trowelled surface; seeding said trowelled surface with a pre-selected aggregate to create a desired surface effect; continuing to trowel said surface until firm to form a hardened surface having seeded pre-selected aggregate buried therein; allowing said surface to cure for ½ to 2 hours; spraying said surface with a chemical surface retarder and covering said surface using plastic sheeting; allowing said mixture to set for at least 12 hours; and, thereafter, alternately sanding and power washing said surface and cutting said pre-selected aggregate open until a desired degree of surface smoothness and exposure of said surface effect has been achieved.
