ST Hydra Stone is a non-yellowing, waterbased
compound containing ST matrix acrylic polymers
that offers outstanding curing, sealing, dustproofing,
increased abrasion and chemical resistance
for freshly finished ST material surfaces. ST Hydra
Stone has been formulated to form a membrane
film on the surface of the concrete that optimizes
water retention for maximum concrete hydration
and compressive strength. ST Hyrda Stone will
appear milky white in the container and dries to a
clear film. Can be used on any ST finished surface
that is not yet sealed. ST Hydra Stone is an
excellent interior or exterior sealer for horizontal or
vertical ST surfaces.
