Seal-N-Grip TM

HARDWOOD ADHESIVE, MOISTURE CONTROL & SOUND REDUCTION MEMBRANE

KEY FEATURES

-    One-step application reduces Labor, time and cost

-    Moisture vapor & sound protection

-    Great for solid and bamboo flooring

DESCRIPTION

Bostiks Seal-N-Grip TM is a high performance adhesive, moisture control, and sound reduction membrane all in one. Its superior properties provide a tough, flexible, tenacious bond to a variety of surfaces, and it is not adversely affected by exposure to moisture, water or alkalinity. Seal-N-Grip TM 's elastomeric characteristics allow the adhesive to move with the wood as it expands and contracts over the life of the floor. Seal-N-Grip TM exhibits exceptional green grab or high tack immediately after troweling, making installation easier and more secure. This adhesive contains 1% recycled rubber material, has zero VOC's (as calculated per SCAQMD Rule 1168) and does NOT contain any water. Seal-N-Grip TM contains Bostiks BLOCKADET 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.

THICKNESS CONTROLT SPACER TECHNOLOGY

Seal-N-Grip TM contains Bostik's patent-pending Thickness ControlT Spacer Technology. This proprietary feature helps ensure proper membrane thickness is maintained between the hardwood flooring and substrate. Installers can use mallets to engage the tongue and groove or even walk on their work during the installation process without significant reduction in the film thickness that could compromise moisture protection and sound control.

MOISTURE PROTECTION

Seal-N-Grip TM has very low moisture vapor permeability and is not adversely affected by moisture. As a result, it will reduce moisture vapor transmission through the concrete. When applied as directed as a moisture vapor membrane, it will prevent damages caused by moderate/high subfloor moisture. Seal-N-Grip TM may be used for concrete slabs as an adhesive and moisture vapor control membrane on slabs with elevated moisture levels up to 15 lbs. per 1,000 square feet per 24 hours (using an anhydrous calcium chloride test kit according to ASTM

SOUND CONTROL

Seal-N-Grip TM provides a premium sound reduction barrier over the substrate that typically outperforms %" thick cork underlayment. This eliminates the costly labor and materials required to transport and install these secondary acoustical sheet membranes. Independent testing laboratory results are summarized on the Acoustic Performance Chart.

ANTI-FRACTURE PERFORMANCE

Seal-N-Grip TM 's elastomeric characteristics establish an antifracture membrane that can bridge cracks up to 1/8" (3mm) which can occur in the substrate prior to or after installation. This superior elasticity allows the adhesive to move with the wood as it expands and contracts with changes in humidity and temperature over the life of the floor.


ULTIMATE VERSATILITY

This high performance formulation may be used to adhere all engineered, solid, bamboo, cork, and parquet. Seal-N-Grip TM  has no restrictions on board width or length. It may be used over all properly prepared substrates common to hardwood flooring installations including; concrete, plywood, OSB, well bonded vinyl/VCT and ceramic tile, cement backer board, gypsum underlayments (dry, above grade), cement patch/ underlayments, radiant-heat flooring, and properly prepared terrazzo. This adhesive can also be used to install plywood as described, as well as ceramic tile, marble, and stone inlays for light commercial and/or residential applications.

LEED CONTRIBUTION

This 0 VOC formulation (as calculated per SCAQMD Rule 1168) may contribute toward LEED credits under section EQ 4.1: Low-Emitting Materials-Adhesives & Sealants. It also contains 1% recycled rubber material contributing to LEED credits under section MR 4.2: Recycled Content.

DIRECTIONS FOR USE

Read and understand data sheet completely before beginning installation. Follow industry standards and flooring manufacturer's recommendations for acclimation, design, layout, and application of wood flooring material. If jobsite conditions are outside of flooring manufacturer's recommendations, take necessary corrective actions. Whether the moisture content of substrate exceeds or is within the flooring manufacturer's recommendations, to address current or possible future subfloor moisture, sound, and cracks (up to 1/8"), apply Bostik's Seal-N-Grip TM as directed.

SURFACE PREPARATION

Surfaces must be absorptive, clean, and free from loose materials, oil, grease, sealers, curing compounds, waxes, silicates, laitance, and all other surface contaminants that may inhibit proper bond. Completely remove cutback adhesive residue or other surface contaminants by diamond grinding to open the pores of the concrete. All surfaces to be treated must have a concrete surface profile (CSP) of 1-3 (similar to a broomed finish), as defined by ICRI (International Concrete Repair Institute, Guideline No. 03732). Maximum acceptable floor variation is 3/16" in 10 feet. Areas requiring patching or leveling must be done using a Portland cement-based material (e.g., Bostik's UltraFinishT, Webcrete 95, Webcrete 98, or SL-150T Self-Leveling Underlayment).  PLEASE NOTE: Concrete substrate should NOT be smooth and reflective; it must have a concrete surface profile of CSP 1-3 (similar to a broomed finish), as define by ICRI (International Concrete Repair Institute, Guideline No. 03732). It is advisable to test for adequate substrate absorption and 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

The installation begins with a starter row secured to the subfloor; the starter row provides a stationary point to push against so flooring doesn't move during installation. Once the starter row is secured, apply adhesive/membrane to substrate using the appropriate trowel. See the chart on last page for trowel suggestions. Flooring may be installed using a "Wet-Lay" or "Walk-On-Work" methods of installation. For either type of installation, spread the adhesive and begin to install the flooring immediately. Periodically lift boards immediately after installation to ensure proper slab coverage and transfer to the back of the flooring. As you work, immediately clean any adhesive from prefinished flooring with Bostik's UltimateT Adhesive Remover or mineral spirits (be careful not to harm finish), then dry buff with a nonabrasive paper towel. After a few rows have been installed, and as you move across the room, tape the boards together using removable 3M #2080 Blue tape to prevent boards from sliding and to secure close-fitting joints. Rolling is recommended for all installations. Flooring that is not flat should be tacked, weighted, or rolled to ensure proper contact between the flooring and substrate.

PLYWOOD OVER CONCRETE: Score 4' x 4' or 2' x 8' sheets of 3/4" exterior-grade plywood on the backside every 8" to 10" by using a circular saw and cutting one-half the thickness of the plywood; "scoring or kerfing" takes the tension out of the plywood and helps to prevent possible warping or curling. Apply adhesive/membrane to substrate and then set plywood into the wet adhesive/ membrane. Allow the adhesive/membrane to fully cure before nailing or using Bostik's Seal-N-Grip adhesive/membrane to install flooring. If nailing to the plywood, nails must not protrude through to the adhesive/membrane.

CLEAN UP

As you work, immediately clean any adhesive from prefinished flooring with Bostik's UltimateT Adhesive Remover or mineral spirits (be careful not to harm finish), then dry buff with a nonabrasive paper towel. Immediately clean all tools and equipment with Bostik's UltimateT Adhesive Remover or mineral spirits before material cures.

TROWEL CLEAN-UP TIP: Before use, cover areas of the trowel that are not used to spread the adhesive with blue tape. After use, simply tear off tape before material cures, and clean the remainder of the trowel with adhesive remover.

STORAGE/SHELF LIFE

Store at temperatures between 50F and 100F (10C and 38C). Shelf life is one year from date of manufacture in closed, original packaging.

Re-Seal Partially Used Container: With pail upright place a sheet of plastic (e.g., trash bag) over the top of the pail. Secure lid tightly over the plastic on top of pail. Carefully turn pail upside down. Plastic will help prevent the material from bonding the lid closed.  Re-Open Partially Used Container: Carefully turn pail right side up. Remove lid. Carefully cut and discard cured material and plastic from top of pail. Any uncured material may be used.


LIMITATIONS

  • Periodically check coverage of adhesive during installation; 100% substrate coverage and adhesive transfer is required to protect against damage from subfloor moisture.
  • Due to limitations with solid and bamboo wood flooring (e.g., lack of dimensional stability), "below-grade" installations are limited to engineered hardwood flooring.
  • For substrates with any history of moisture problems, or for concrete slabs exceeding 15 lb MVER or 85% RH, use a high performance moisture vapor reduction product such as Bostik's UltraGrip.
  • Do not install solid wood or bamboo flooring over VCT/vinyl.
  • Bamboo installations should follow solid hardwood flooring installation recommendations.
  • Slab temperature should be between 50F and 95F (10C and 35C) during installation.
  • Do not use on wet, dusty, contaminated, glassy smooth or friable substrates; do not use over substrates/slabs treated with sealers or curing compounds.
  • Do not use in areas subject to hydrostatic head.
  • Completely remove all adhesive residue and other surface contaminants by diamond grinding, shot blasting, or scarifying.
  • Do not use over perimeter bonded flooring material.
  • Use over gypsum-based underlayments is limited to dry, "abovegrade" installations where the gypsum has dried hard (not dusty/ powdery), with a minimum compressive strength > 2,000 psi for engineered hardwood installations, or minimum compressive strength > 2,500 psi for solid hardwood installations.
  • Please refer to flooring manufacturer's recommendations and NWFA's specifications for proper acclimation, verification of moisture content of flooring with a moisture meter, and expansion relief around perimeter throughout installation.
  • Do not use with vinyl-backed cork flooring or foamed-backed parquet.
  • This membrane is designed to reduce moisture vapor emissions that originate/emanate from below the membrane only.
  • This membrane does NOT reduce/affect issues originating from the sides, ends, or top of flooring (ie. puddles, water, leaks, hydrostatic-head, etc.).
  • This membrane does NOT eliminate all possible moisture related or install related issues (i.e. improper acclimation of flooring, jobsite temperature/relative humidity, etc.).
  • This membrane is designed to prevent excessive variance of moisture between the top, middle, and bottom of flooring that originates from the substrate.

TROWEL SELECTION

In order to form a membrane that functions properly for moisture vapor protection and/or sound reduction, the right trowel needs to be selected to achieve both 100% coverage of the substrate and 100% transfer to the back of the flooring. Jobsite conditions, profile of the substrate, depth of back channeling in the flooring, and other factors affect the amount of adhesive that must be applied to achieve proper coverage and transfer. Always pull a board at the beginning of and during the installation process to confirm adequate coverage and transfer. Trowel size may need to be changed to achieve the required coverage and transfer. See trowel suggestions below.

ADHESIVE & MOISTURE MEMBRANE INSTALLATION METHOD

Suggested Trowel (For use as an adhesive only, refer to adhesive only installation method.)

Solid, engineered or bamboo wood flooring up to 5/8" thick. Coverage: 30-35 sq.ft. per gallon

Solid, engineered or bamboo wood flooring >5/8" thick, or plywood. Coverage: 20 sq.ft. per gallon

1/4" x 1/4" V-Notch  

1/4" x 1/4" x 1/4" Square Notch

1/2" x 15/32" V-Notch

1/4" x 3/8" x 1/4" Square Notch

Trowel size is suggested to maximize coverage of adhesive. Periodically lift a board to ensure the following conditions are being met: 100% coverage of concrete substrate and 100% transfer to the back of the flooring product. Uneven subflooring may require the use of either a leveling/patching material, or a larger V-notched trowel for proper coverage of adhesive.

ADHESIVE ONLY INSTALLATION METHOD

Suggested Notched Trowel (For use as an adhesive and moisture control membrane, refer to chart above.)

Engineered hardwood flooring <1/2" thick. Coverage: 50 sq.ft./gallon

<1/2" Parquet, or cork underlayment.

Coverage: 80 sq.ft./Gallon

Engineered hardwood flooring >1/2" thick, Solid wood or bamboo flooring <1/2" thick, and parquet <3/4" thick. Coverage: 40 sq.ft./gallon

Solid wood or bamboo flooring >1/2" thick, or plywood. Coverage: 35 sq.ft/gallon

Trowel size is suggested to maximize coverage of adhesive. Periodically check coverage of adhesive during installation: > 80% coverage and transfer to the back of the flooring is required for all engineered wood flooring; > 95% coverage and transfer is required for all solid wood flooring or bamboo flooring products.
