Durable Pool Plaster, Revisited
In December 2010, WaterShapes published "How to Make Durable Pool Plaster," an article filled with what I knew about making reliable, discoloration-free pool plaster - including basic information about both proper and improper plastering practices. It should come as no surprise that, since then, research has continued and our understanding of issues involved in the proper mixing and application of these cementitious finishes has continued to grow. This article will cover these developments, discussing in greater detail the
Good Chemistry
