Where to use - Swimming pool plaster and stucco

Swimming pools and fountains must perform under some of the toughest conditions imaginable: constant exposure to water, harsh pool and cleaning chemicals, freeze-thaw conditions, and the critical eye of fussy owners. That's why Engelhard offers a way to make pools better by improving the plaster - so pool plasters are easier to apply, meet the challenges of their environment, and maintain their appearance and smooth surface for years longer.

Color changes, surface imperfections, and areas of weakness in plaster can result when lime, created as an undesirable byproduct of cement hydration, leaches from the hardened plaster. But MetaMax® PA high quality pozzolanic plaster additive is uniquely engineered to react with lime to form additional cementitious products, resulting in a more durable plaster finish. In addition, MetaMax PA produces a plaster with a creamy texture, improving the plaster's trowel ability and making it easier to apply and finish.

Over the past decade and in more than 40,000 swimming pools, results show that MetaMax PA reduces permeability of portland cement-based plasters and improves the surface appearance of hardened plaster. Its white color is perfect for architectural applications, white and colored plaster, and exposed aggregate finishes.  

Increase Production	Improve Appearance	Improve Performance	Improve Customer Satisfaction
Improve troweling Reduce bleed water Reduce premature setting to give plasterers greater control over finish. Minimal plaster dust for easier start-up.	Maintain high whiteness Create more vibrant colors Reduce spot etching Reduce cracking Reduce mottling Reduce efflorescence Reduce color pigment “fade”	Improve aggregate bonding Increase chemical resistance Reduce permeability Increase strength Reduce alkali silica reactivity Less shrinkage cracking	Smoother surface finish to touch Lower alkalinity in pool start-up water Resistant to staining and discoloration Easier long-term maintenance
