Applicable Standards

American National Standards Institute (ANSI) ANSI A108.10 and A118.6 American National Standards for the Installation of Ceramic Tile ASTM International (ASTM)

  • ASTM C109 Standard Test Method for Compressive Strength of Hydraulic Cement Mortars (Using 2-in. or (50-mm) Cube Specimens)
  • ASTM C531 Standard Test Method for Linear Shrinkage
  • ASTM C580 Standard Test method for Flexural Strength


Polyblend? Non-Sanded Grout exceeds ANSI A118.6 standards.

Conformance to Building Codes

Installation must comply with the requirements of all applicable local, state and federal code jurisdictions.

Composition of Product

Polyblend? Non-Sanded Grout is a dry, Portland cement based grout, inorganic aggregates and chemicals.

Environmental Consideration

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:

  • Up to 2 points towards MR Credit 5, Regional Materials
  • Up to 1 point towards IEQ Credit 4.1, Low-Emitting Materials – Adhesives & Sealants

Suitable Tile Types

  • Vitreous, semi-vitreous or non-vitreous tile
  • Impervious porcelain and glass tile
  • Cement-based precast terrazzo
  • Natural stone tile

General Surface Prep

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.

Health Precautions

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.

Limitations to the Product

  • Should not be installed when ambient or surface temperature is lower than 50°F (10°C) or higher than 100°F (38°C).
  • 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.
  • Color variation can occur due to tile type, tile porosity, jobsite conditions, application and cleaning techniques. Variation can be minimized by following directions and using as little water as possible for cleanup.
  • 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 us an appropriate caulk or sealant such as?Commercial 100% Silicone Caulk?or?Polyblend? Ceramic Tile Caulk.

Mixing Ratios

  • Mix 2.9 pt (1.4 L) clean water to 10 lb (4.5 kg) grout.
  • Mix 7.25 pt (3.43 L) clean water to 25 lb (11.34 kg) grout.
  • For 1 lb (.45 kg) grout, see package for fill line indicator.

For increased stain resistance use StainBlocker for Grout Additive. See datasheet for details.

Mixing Procedures

Dry mix bags of different batches together as they can vary slightly in color. Mix with a trowel or low speed mixer (less than 300 rpm) for approximately 3 minutes to achieve a smooth, lump-free consistency. If needed add: up to 0.2pts (0.1L) of water for each 10 lb. (4.5 kg) powder. Let the mixture stand (slake) for 5 minutes, and then remix and use. Periodically remix grout to keep it workable but do not add water as it can weaken the grout, cause color variation, shrinkage, cracking and pinholes. Discard grout when it becomes too stiff to spread.

Application of Product

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 of Product

Curing time is affected by ambient and surface temperatures and humidity. For exterior applications, it is recommended that the installation is misted periodically with clean, cool water for 3 days.

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 exterior 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?TileLab? SurfaceGuard??or?Aqua Mix? Sealer's Choice? Gold.

Cleaning of equipment

Clean tools and hands with water before the material dries.

Product Maintenance

Clean with a pH-neutral cleaner such as Aqua Mix AquaKleen, Aqua Mix Concentrated Tile & Stone Cleaner?or TileLab Grout & Tile Cleaner.
