Bostik LVT-Lock




KEY FEATURES

-    Rapid tacking
-    Bonds a wide variety of flooring
-    Plasticizer migration resistant

DESCRIPTION

Bostik LVT-LockTM is a solvent-free, single-component, water-based, acrylic adhesive specifically formulated for the installation of most resilient flooring. LVT-LockTM is a 0-VOC formulation as calculated per SCAQMD Rule 1168. LVT-LockT is formulated using special acrylic polymer emulsions and tackifiers that enable either "wet-set" or "transitional pressure sensitive" installation methods. It displays tenacious early bond strength, and is specially formulated to be highly resistant to plasticizer migration and staining. LVT-LockTM has been formulated to exhibit a unique combination of application properties including; excellent trowelability, fast tack/grab, low odor and easy clean up.

LVT-LockTM may be used for bonding LVT (Luxury Vinyl Tile), rubber, carpet, felt-backed linoleum, and cork floor coverings, as well as, rubber and vinyl, stair treads and nosing. It may be used over all properly prepared concrete, plywood, cementitious-based patch/underlayments, terrazzo and radiant heat systems.

LVT-LockTM comes with Bostik's BLOCKADEŽ antimicrobial protection, which inhibits the growth of bacteria, mold, or mildew on the surface of the dried adhesive; the dried adhesive resists stains caused by mold or mildew.

DIRECTIONS FOR USE

Read and understand the data sheet completely before beginning installation. Follow the appropriate industry standards, including ASTM F710 Standard Practice for Preparing Concrete Floors to Receive Resilient Flooring.

Resilient flooring materials have vastly different substrate preparation and installation requirements that are essential to a successful installation regardless of flooring material or adhesive being installed. Always do a test area to ensure product satisfaction, including adhesion to substrate, and/or to become familiar with proper application techniques prior to use. Periodically lift away a section of the floor covering to assure that proper coverage is being attained.

SURFACE PREPARATION

Surfaces must be clean, dry and flat; free of voids, projections, loose materials, oil, grease, sealers and all other surface contaminants. Mechanically remove all surface contaminants by grinding or scarifying the substrate. Surface areas requiring patching or leveling must be treated using Bostik UltraFinishTM, WebcreteŽ 95TM, or WebcreteŽ 98TM cement patches and/or Bostik SL-150TM Self-Leveling Underlayment. Refer to the technical data sheets for these products for proper installation.

Bostik D-250TM Moisture Vapor Barrier Coating or D-261TM Extreme Moisture Vapor Barrier Coating are recommended for installations where excessive moisture and/or alkalinity issues may exist or might occur from the concrete slab. Please refer to the "Installation" section for proper installation methods when using these moisture vapor barrier coatings.

PLEASE NOTE: Concrete substrate should NOT be smooth and reflective; it must have a concrete surface profile of CSP 1-3 (similar to a light broom finish), as defined by ICRI (International Concrete Repair Institute, Guideline No. 03732). It is advisable to test for adequate substrate texture in several areas throughout the jobsite by sprinkling droplets of water onto the slab. The drops of water should show signs of penetrating the substrate within one minute. This is evidenced by a water stain on the concrete without a "domed" droplet. If no signs of water penetration are shown within one minute and "domed" droplets remain (similar to drops on a car hood) the substrate will need to be mechanically textured.

INSTALLATION

Spread LVT-LockTM evenly with the proper trowel as described below. Open time is influenced by substrate porosity and atmospheric conditions (i.e. temperature, humidity, and air movement). For best results, maintain adhesive, floor covering, and room at a stable temperature of 50°F to 85°F (10°C to 30°C) for 24 hours before and after installation. Refer to the suggested trowel and flash time chart below for suggestions specific to the type of floor covering you are installing. Follow manufacturer's recommendations for rolling and/or cross-rolling the flooring during installation. Periodically check back of floor covering to ensure >80% coverage of flooring material's backing.

Applications Over D-250TM or D-261TM Moisture Vapor Barrier Coatings : LVT-LockTM must not be installed directly over D-250T or D-261TM without a 1/8" thick minimum cementitious layer. Refer to the technical data sheets for these products for proper application instructions.

CURE TIME

Higher temperatures affect the rate of cure, the higher the temperature the faster the cure. Porosity of the substrate and flooring materials also affect cure times. Under normal conditions (70°F (21°C) and 50% RH), light foot traffic is acceptable after 8 to 10 hours; normal traffic after 24 hours.

CLEAN UP AND STORAGE

As you work, immediately clean any adhesive from resilient flooring using a clean rag with soap and water. Immediately clean all tools and equipment before adhesive cures. Follow flooring manufacturer's recommendation for clean up. Use mineral spirits to remove dried adhesive. Some flooring may not be compatible with solvents such as mineral spirits. The product should be stored in the original container in a cool, dry place and out of direct sunlight. Do not allow product to freeze.

LIMITATIONS

  • This product is for interior installations only.
  • Do not use this product where excessive moisture and alkalinity are present as specified by the flooring manufacturer.
  • Test all concrete slabs for moisture per ASTM F1869 to determine the Moisture Vapor Emission Rate (MVER), or ASTM F2170 to determine RH. For slabs exceeding 5 lbs. per 1,000 sq. ft. (1,36 kg per 92,9 m2) per 24 hours or 80% RH, treat with Bostik's D-250TM or D-261TM Moisture Vapor Barrier Coating. Please refer to D-250TM or D-261TM Data Sheets.
  • Do not use this product directly over D-250TM or D-261T Moisture Vapor Barrier Coatings. A 1/8" layer of Bostik WebcreteŽ 95, WebcreteŽ 98, SL-150T, or UltraFinishTM with their proper primers must be installed on top of D-250T and D-261TM prior to the application of LVT-LockT. Refer to product instructions or contact Bostik Technical Service.
  • Slab temperature should be between 50°F and 95°F during installation. Large fluctuations in temperature during installation and cure should be avoided.
  • Do not use on wet, dusty, contaminated, or friable substrates; do not use over substrates/slabs treated with sealers or curing compounds; do not use in areas subject to hydrostatic head.
  • Do not allow heavy traffic or rolling loads for a minimum of 24 hours.
  • Prior to applying adhesive to rubber stair treads, lightly sand the entire back of the tread and nosing and wipe with denatured alcohol to remove any contaminants that may interfere with proper adhesion. This method does not apply to homogeneous recycled rubber flooring used for stair tread applications.
  • Do not use LVT-LockTM over any gypsum-based materials.
  • Test all concrete slabs for alkalinity per ASTM F710 to determine the pH level. For slabs exceeding 9 on the pH scale, treat with Bostik's D-250TM or D-261TM Moisture Vapor Barrier Coating. Please refer to D-250Tor D-261TM Technical Data Sheets.
