Description

NeverSealTM Commercial Grade Pre-Mixed Grout is a patented, ready-to-use, water-based, urethane grout for interior and exterior installation of ceramic, porcelain, glass and natural stone tiles on floors and walls with grout joint widths from 1/16" to 1/2". Designed for residential and commercial applications, NeverSeal offers lifetime stain resistance, superior crack protection and uniform color consistency. It contains built-in, urethane sealer technology so it NEVER needs to be sealed and is ideal for use in heavy traffic areas as well as wet/submerged environments.

NeverSeal's quartz aggregate is color coated to ensure uniform color consistency every time; unlike other grouts that contain loose color pigments which can cause staining or be washed away during the initial mixing or clean-up steps.

NeverSeal contains Bostik's BlockadeTM antimicrobial protection, which inhibits the growth of bacteria, mold, or mildew on the surface of the dried grout and enables it to resist stains caused by mold.

NeverSeal is a technology engineered to appeal to today's green-conscience marketplace, specifically those seeking to obtain U.S. Green Building Council LEED certification for their projects. Its unique combination of features and benefits produces one-of-a-kind specification potential for architects and designers .

* With immediate cleaning and proper maintenance, NeverSeal is resistant to staining when exposed to the most common household goods and cleaning agents. Long-term exposure to any material can increase the potential for staining.

Directions for Use

Read and understand Technical Datasheet and Material Safety Datasheet completely before beginning installation. Always use protective clothing (gloves and eye protection) when working with grout. When installing your tile, follow applicable ANSI, TCNA and NTCA installation standards.

ALWAYS DO A TEST AREA TO ENSURE PRODUCT SATISFACTION OR TO BECOME FAMILIAR WITH PROPER APPLICATION TECHNIQUES PRIOR TO USE.

Surface Preparation

Ensure tile is firmly set and mortar/adhesive is completely dry (typically 8 to 12 hours - always follow mortar/adhesive manufacturer's instructions) before grouting. Remove all spacers, water, debris and adhesive from tile joints. For best results, surface of tile should be at room temperature 70F (21C) - 75F (24C). Urethane materials are affected by temperature and humidity variations. Cool temperatures and/or high humidity will extend cure time.

To facilitate cleaning, pre-seal all porous tile and natural stone with a water-based sealer before grouting; ensure that sides of tiles are sealed as well. For glass tile, metal tile, polished marble, stone and other soft surfaces, test grout on a small area to ensure compatibility and scratch-free application. Make sure tile and grout joints are clean and free from solvents/residues before grouting. To speed up installation and reduce potential hazing, or for quarry and other porous tile and/or outdoor applications, pre-wet tile surface using a damp, clean sponge prior to spreading grout. Be careful not to leave standing water on the surface of the tile or in the grout joints.

Mixing

DO NOT add any water, liquid, or other material to NeverSeal! This will cause grout failure and void all warranties. A translucent, milky liquid may be present on the surface of the grout upon opening the container. This is from normal settling during shipment.
Mix grout in its pail with a margin trowel to bring grout to a uniform mixture. This mixing process should be approximately one minute. Use of a drill mixer is not recommended as it will introduce excessive air into the product and cause grout sagging on vertical applications, pin holes, and/or other performance issues. Continue to remix grout with margin trowel throughout the grouting process.

Installation

NeverSeal is a new grout technology that allows a simpler application and cleanup process. Pre-treat tile surfaces per Surface Preparation section instructions. Spread grout over the face of the tile using a green, sharp-edged, firm (epoxy/urethane) grout float. Work the grout back and forth at a 45 angle to the face of the tile to ensure that grout joints are fully packed, especially in tight and irregular joints.

Spread only within an area that you can reach (arm's length) to apply and clean NeverSeal at any one time. Remove all excess grout by holding the rubber float at a 90 angle, working diagonally across the face of the tile to prevent grout removal from joints.

Prior to re-grouting applications, completely remove all old grout and any surface contaminants. Be sure to rinse any residual cleaner/solvent out of grout joints, then allow joints to completely dry before re-grouting.

Open Time

NeverSeal's typical open time is 3 hours. Hot and dry conditions reduce the grout's open time, while cold and humid conditions extend it. NeverSeal's liquid urethane binder should be wet in appearance. Do not install grout that has liquid urethane binder that has skinned over or appears dry.

Clean-up

For best results, remove grout haze as you work, particularly in warm or dry climates. If working alone, only grout as far as you can reach (arm's length) before initial cleaning. If working as a team, one person should grout, with the other(s) cleaning immediately behind the first person.

Clean/rinse sponge in water and wring nearly dry. During installation, urethane grout requires very little water to clean; using too much water during cleanup will dilute the urethane binder and cause curing issues.

Clean surface of the tile with a flat sponge, being careful to remove all excess grout and haze. Wipe up spilled water immediately; do not allow water to sit on grout surface or in ungrouted joints. Excessive water used during clean-up can dilute the urethane binder and cause curing issues that may lead to grout failure.

Change water after each 100 square feet, for each new bucket of grout, or when water is dirty or milky in appearance. Check work as you clean. Repair any low spots with additional grout. Unlike other grouts, DO NOT wash too vigorously.

Cure Time

Humidity affects cure to a greater degree than temperature; the lower the humidity, the faster the cure. Under normal conditions, light foot traffic is acceptable after 24 hours; heavy foot traffic after 72 hours. If grouting in ANY wet area wait 7 days before use.

See Limitations for further curing requirements.

Secondary Cleaning

(if necessary)
Allow cleaned areas to dry, and then inspect tile/stone surface. If a second cleaning is necessary, wait 3 hours in low humidity environments and 6 hours in high humidity environments, making sure grout is cured enough to withstand light finger pressure without losing form. Then spray Bostik's BlazeTM Urethane Grout Cleaner on a scrub pad designed for delicate surfaces such as the 3M DoodlebugTM white cleaning pad. Do not flood the surface with cleaner. Rub the cleaning pad lightly over any remaining urethane haze, allow it to dwell on the tile / stone surface for at least 60 seconds (excessive haze may require direct spray on surface and/or more dwell time) to ensure sufficient penetration. Use a damp sponge and clean water to remove the film and cleaner. Finish by drying the tile surface with a clean towel or cloth. Contact Bostik Technical Service at 1-800-7/BOSTIK if a persistent haze exists.

Limitations

  • Follow manufacturer's instructions for all other setting materials, waterproofing, anti-fracture membranes, etc. used on the job.
  • Minimum recommended grout joint width is 1/16" for floors and walls.
  • Maximum recommended grout joint width is 1/2" for floors and 1/4" for walls.
  • Do not use as a setting mortar.
  • Not for use in heavy industrial applications (i.e., chemical plants), in areas subjected to harsh or persistent chemicals, or areas exposed to very aggressive cleaning routines such as pressure washing or steam cleaning.
  • NeverSeal is not a replacement for a waterproofing membrane. When a waterproofing system solution is required, please consult Bostik Technical Service.
  • Protect grout from stains and chemicals during the cure process.
  • Do not grout when tile surface is above 85 F (30 C).
  • Do not use vinegar or acid solutions for clean up.
  • Do not use for commercial re-grouting or wet environment re-grouting installations, including showers, steam showers, and outdoor applications.
  • Outdoor installations must be protected for 7 days by tenting the grouted area (at least one foot above surface).
  • Steam shower/wet area installations must be protected from moisture and allowed to cure for 7 days.
  • Wait 7 days before exposing grouted area to water and/or household cleaners.
  • Wait 7 days prior to exposing grout to full water submersion.
  • Use care on soft, highly polished surfaces to avoid scratching. Test a small area. Use of a sealer before grouting is always recommended on polished marble, stone, slate and other natural, porous tiles.
  • Use an approved waterproofing membrane over mud bed applications. Follow manufacturer's recommendations for all waterproofing materials. For liquid applied waterproofing materials, apply to within 1" of any drains to prevent weep hole blockage.
  • Use of enzymatic floor cleaners will void all warranties.
  • Caulk all corners (change of plane or expansion joints).
  • Not for use in hot tubs.

Storage and Shelf Life

NeverSeal is guaranteed to remain suitable for use up to a period of two(2) years from the date of manufacture if stored unopened at temperatures above 32F/0C - 100F/38C. After opening, NeverSeal can be saved for reuse if properly resealed in original container (always wipe the pail lip clean prior to resealing to ensure proper seal is achieved with the vapor lock lid). If product freezes, return to room temperature and use as directed.

Packaging

NeverSeal is available in 9 lb and 18 lb pails.

Color Selection

The NeverSeal Grout Selector Card is the standard for color selection, manufacturing and quality control. Colors may vary due to jobsite conditions, absorption of tile, installation methods, or from batch to batch, and therefore may vary significantly from the NeverSeal Grout Selector Card.

PRECAUTIONS: Avoid contact with eyes and skin. Use adequate ventilation. Wash thoroughly after handling. Store container in a cool, dry area. Do not reuse container.
FIRST AID: In case of contact with eyes, flush eyes with water for at least 15 minutes and call a physician. If ingested, seek immediate medical attention.
FIRE: Dry chemical, foam, carbon dioxide or water.
