The American National Standards Institute has given its final approval of the ANSI/APSP/ICC/NPC-12 Standard for the Plastering of Swimming Pools and Spas. The newest APSP standard will be available for sale in late December.

This standard covers material and application for the plastering of cementitious finish coatings for in-ground swimming pools or other cementitious water-containment vessels. It sets forth the identification and stipulation of non-structural cementitious finish coating materials for usage in plastering of water-containment vessels, the application and finishing methodologies, based on common accepted trade practice, for the installation of non-structural cementitious interior finish coatings for water-containment vessels and more.
