Products : Grout : Cement Grout : Prism® Ultimate Performance Grout
Prism® Ultimate Performance Grout sets a new standard in cement-based grout technology. Prism's calcium Aluminate cement based 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.
American National Standards Institute (ANSI) ANSI A108.10 & A118.7 of the American National Standards for the Installation of Ceramic Tile ASTM International (ASTM)
Prism® SureColor® Grout meets ANSI A118.6 and A118.7 standards.
Installation must comply with the requirements of all applicable local, state and federal code jurisdictions.
Prism® grout is a blend of specialty cements, recycled aggregates and chemicals.
Custom® Building Products is committed to environmental responsibility in both products produced and in manufacturing practices. Use of this product can contribute towards LEED® v3 certification:
USE CHEMICAL-RESISTANT GLOVES, such as nitrile, when handling product.
Tile or stone must be firmly bonded to a sound substrate, and setting material must be cured a minimum 24-48 hours before cement grout is applied, unless rapid-setting mortars are used. See the corresponding data sheet for the bonding mortars used in your application. Remove spacers and ensure that the grout joints are uniform in depth and width and free of loose debris, contaminants and excess mortar. Use TileLab® SurfaceGard® Sealer or Aqua Mix® Grout Release to seal tile or stone subject to staining or when using a grout that contrasts with the color of the tile.
This product contains Portland cement. Avoid eye contact or prolonged contact with skin. Wash thoroughly after handling. If eye contact occurs, flush with water for 15 minutes and consult a physician. Use with adequate ventilation; do not breathe dust and wear a NIOSH approved respirator. If ingested, do not induce vomiting; call a physician immediately.
Mix 4-5 pt (1.89-2.36 L) clean water to 17 lb (7.71 kg) box. Mix only with cool, potable water.
When installing more than 1 container of grout at a time, blend dry powders prior to mixing with water. Mix with a trowel or low speed mixer (less than 300 rpm) to achieve a smooth, lump-free consistency. Let the mixture stand (slake) for 10 minutes, and then remix and use. Periodically remix to keep the mixture workable, but do not add water, which can weaken the grout, cause color variation and possible cause shrinkage, cracks and pinholes. Discard grout when it becomes too stiff to work.
Installation must conform to ANSI A108.10. Lightly dampen absorptive, highly porous tile with clean, cool water, but leave no standing water in the joints. Holding a rubber grout float at a 45° angle, completely fill the joints. Holding the edge of the float at a 90° angle, remove excess grout. At 70° F, do not spread more grout than can be cleaned within 30 minutes of the grout firming and use as little water as possible for grout clean-up (higher temperatures may shorten this time frame). Using a damp, small pore grout sponge in a circular motion, smooth and level joints and remove excess grout. Change the water and rinse the sponge frequently. Haze can be removed after 3 hours with cheesecloth or wrung-out sponge. If haze persists, the installation can be washed after three days with Aqua Mix NanoScrub or after ten days with Aqua Mix® Sulfamic Acid Crystals, TileLab® Sulfamic Acid Cleaner or Aqua Mix® Cement Grout Haze Remover. Perform a test in an inconspicuous area prior to complete application. Movement joints are required for perimeters and other changes of plane in all installations. See TCNA Detail EJ171 for recommendations.
Curing time is affected by ambient and surface temperatures and humidity. Use the following as a guideline. For exterior applications in hot, dry and windy conditions, it is recommended that the installation is periodically misted with clean, cool water for 3 days. Can be subjected to intermittent water exposure after 3 days. For submerged applications, allow grout to cure for 14 days before filling the area with water.
Exterior applications must be protected from rain, snow and other wet conditions for at least 7 days with temperature above 50° F (10° C). If inclement weather is expected, protect the work area with tenting at least 1 foot (30 cm) above the finished surface to allow air flow. Enclose and protect installations and maintain >50° F (10° C) temperatures for at least 72 hours for proper cure.
Sealing of Grout
Use a pH-neutral, water-based sealer such as AquaMix Sealer's Choice Gold or TileLab Surface Guard.
Clean tools and hands with water before the material dries.
Clean with a pH-neutral cleaner such as Aqua Mix AquaKleen, Aqua Mix Concentrated Tile & Stone Cleaner or TileLab Grout & Tile Cleaner.
