3 Product Description
Prism® Ultimate Performance Grout sets a new standard in cement
based grout technology. Prism's calcium Aluminate cement
based, latex polymer-modified formula offers consistent color with no
shading regardless of tile type, temperature or humidity, and it will not
effloresce. The rapid setting formula results in high early strength and
dense joints for the highest stain resistance in grout joints up to 1/2".
A unique blend of lightweight recycled glass and fine aggregate sand
allows for a smooth consistency that is easy to spread and clean.

Limitations to the Product
Should not be installed when ambient or surface temperature is lower
than 50°F (10°C) or higher than 90°F (32°C).
Some ceramic, glass, metal, marble or stone tiles can be scratched
or damaged by the lightweight aggregate filler. Perform a test on a
small area prior to use. Polyblend® NonSanded Grout may be
appropriate for joints up to 1/8" or for tile not suited for sanded grout.
Tile or stone with high absorption, surfaces that are porous or rough,
textured surfaces and some types of porcelain tile may require sealing
prior to grouting to prevent possible staining. Use Aqua Mix® Grout
Release or Tilelab® SurfaceGard® Sealer to prevent staining when
required.
Not for use in either industrial applications or in areas subjected to
harsh or continuous chemicals, high heat or high-pressure cleaning.
For heavy industrial tile installations, use CEG-IG 100% Solids Epoxy
Grout.
Chemicals in salt-based pool filtration systems can cause a reaction
with blue, green and red grouts. Contact Technical Services for
recommendations.
Not for use in movement joints or changes of plane in the tile
installation. In these areas, use an appropriate caulk or sealant such
as Commercial 100% Silicone Caulk or Ceramic Tile Caulk.
