Abstract: A method of creating a smooth-to-the-touch Terrazzo pool finish is disclosed. A mixture of 1 part cement to 1-2 parts crushed marble aggregate, ¼ part pool sand, and sufficient potable water, is mixed until smooth and creamy in texture. The mixture is pumped to the gunite shell of a pool interior surface and hand trowelled onto the shell. In a still soft state, the trowelled surface is seeded with colored and/or high performance aggregate to create desired surface effects. The seeded elements are then trowelled into the upper layers of the surface until hard. After an initial set has taken, the surface is sprayed with a chemical retarder. Once fully set, following 10-20 hours of curing, the mixture surface is power-washed and diamond sanded until smooth-to-the-touch and acceptable in appearance in terms of exposing the previously seeded surface effects. The pool is then filled, chemically treated, and brushed until the surface is no longer dust producing.
