MicroGlass makes pool plaster HARDER and last MUCH LONGER.
MicroGlass: A Pool Plaster Preservation and Renewal System Unlike Any Other MicroGlass provides a revolutionary way to immediately and permanently stop the chemical reactions between the water and the interior finish. Now you can forget about staining from water contaminants (such as iron), and the annoying plaster dust from a new pool finish is virtually eliminated. Protects the plaster finish like glass.
Brands: MicroGlass penetrates micro-cracks, capillaries & voids in pool plaster/aggregate finishes, converting soft calcium hydroxide into a glass-like silicate, making it MUCH HARDER and resistant to damage.
