cementitious materials

Five years ago, Kim Skinner wrote about what was involved in making pool plaster durable. A lot has come to light and been studied and evaluated since then, he says -- more than enough to warrant preparation of a detailed, side-by-side update on the subject.

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

Water and cement-based materials interact in so many ways and on so many levels that it's tough to sort everything out. From initial issues of hydration and curing to a range of longer-term, maintenance-related concerns, says chemistry expert Jeff Freeman, cementitious products in submerged environments react so distinctly to water's presence that it is indeed essential for watershapers to consider what's up when putting them together.
