12 months from the date of production if stored properly

The product must be stored in original, unopened and undamaged sealed packaging in dry conditions and protected from direct sunlight at temperatures between 50°F and 77°F (10°C and 25°C).

Condition material between 59°F and 75°F (15°C and 24°C) before using.

~11.02 lbs/gal (~1.32 kg/L) at 68°F (20°C)

-40°F to 149°F (-40°C to 65°C)

Room temperature between 59°F and 90°F (15°C and 32°C). For ambient temperatures standard construction guidelines should be followed. Follow all floor covering manufacturer’s acclimation and room temperature requirements.

Between 40% and 70% during installation is best for adhesive. See floor covering manufacturer’s recommedations for floor covering requirements.

During laying and until SikaBond®-6100 has fully cured, substrate temperature must be greater than 59°F (15°C) and in the case of radiant floor heating, less than 68°F (20°C). For substrate temperatures, standard construction guidelines should be followed.

Concrete must be dry to touch. Inspect for any wetness at base of drywall or visible signs of moisture on concrete. Concrete and cement-based underlayments must be fully cured and free of any hydrostatic and/or moisture problems. When properly applied in accordance with Sika guidelines, SikaBond®-6100 provides unlimited moisture vapor protection.

SikaBond®-6100 is not affected by moisture or vapor transmission. For protection of the floor covering, follow the floor covering manufacturer’s requirements for subfloor moisture. If substrate is not acceptable, use Sika® MB. See Technical Data Sheet for proper instruction.

Floor may accept light foot traffic after ~6 hours

Curing times depend on environmental and subfloor conditions, adhesive layer thickness and floor covering type. 

~30 minutes at 73°F (23°C) and 50% RH

• These are estimated spread rate coverages and additional adhesive may be required based on substrate porosity/profile/levelness, material wastage or any other variations. Apply material to a test area to calculate the exact coverage for the specific substrate conditions. Trowel diagrams are not to scale.  
• Coverage must be monitored to ensure accuracy of application. Trowel angle may prevent proper coverage.
• Installer is responsible for periodic inspection of the trowel to check for excessive wear. Worn trowels must be replaced immediately.
• The above-listed trowels must be used to obtain proper coverage, larger sizes are acceptable. Excessive amounts of adhesive may cause floor covering to slide while placing, check coverage during installation.

These directions are general guidelines for flooring installations. It is the responsibility of the installer to determine proper drying time of the adhesive, trowel size to be used and acceptability of subfloor conditions. All installations must be in accordance with the flooring manufacturer’s recommendations. Only flooring that is approved in writing for glue down installations by the flooring manufacturer can be used with SikaBond®-6100. Floors installed with SikaBond®-6100 are not warranted against damage caused by wet mopping, flooding, plumbing leaks or other extraordinary circumstances. For any installation not herein recommended, contact Sika before proceeding.

The substrate must be sound, meet the requirements of national standards and must have good compressive and tensile strength.

Substrate must be clean, dry, stable, homogeneous and even, free of all contaminants such as oil, grease, dust and loose or friable particles. Paint, wax, curing and sealing compounds, laitance and other poorly adhering contents that will interfere with the adhesion of SikaBond®-6100 must be mechanically removed, as per ASTM F710.

Note: Adhesion tests on project specific substrates and floor coverings are recommended to be performed.

• SikaBond®-6100 can be used on properly prepared, structurally sound concrete, cementitious patch/underlayment, plywood, VCT, non-cushioned sheet vinyl (excluding self-stick). All floor covering manufacturer’s recommendations must be followed.
• Below grade applications are generally not recommended unless proper precautions are taken to protect the floor covering from subfloor and in-room humidity extremes.
• For on-grade subfloors Sika recommends the use of Sika® MB or Sika® MB EZ Rapid (see appropriate product data sheet for installation instructions and proper details) for best protection against subfloor moisture – moisture testing is required by the floor covering manufacturer for best results with the floor covering products.
• Preparation is a critical step in the installation process and will ensure a successful long term tenacious bond.
• Subfloors must be flat 1/8” (3.18 mm) within a 6’ (1.83 m) radius or 3/16” (4.76 mm) within a 10’ (3.05 m) radius. Remove any high spots with a grinder or sander and fill any low spots with a SikaLevel® patch/level product in conjunction with the correct primer.
• All subfloors must be structurally sound, clean, dry, smooth; free of voids, projections, loose materials, oil, grease, sealers and other surface contaminants that would hinder a good bond. Remove laitance or weak areas mechanically and thoroughly.
• Minimum age of concrete before application must be 21–28 days, depending on curing and drying conditions.
• Concrete substrate must have a concrete surface profile of CSP 1–3.
• For application over newly applied SCHÖNOX® gypsum/hybrid based underlayment products, once the applied product is fully cured, the surface must be cleaned thoroughly with an industrial vacuum before applying SikaBond®-6100. When installing floor covering over old existing SCHÖNOX® gypsum/hybrid based underlayment products, the existing product must first be sealed/primed with SCHÖNOX® VD 1:1 diluted with water, SCHÖNOX® KH FIX, Sika® MB or Sika® MB EZ Rapid. For installation over any other gypsum based substrates, the gypsum must first be sealed/primed with Sika® MB or Sika® MB EZ Rapid.
• For substrates with old well bonded non-water soluble adhesive or adhesive residue use Sika® MB or Sika® MB EZ Rapid. If surface contains asphalt (cutback) adhesive, follow the Resilient Floor Covering Institute “Recommended Work Practices” for removal. When the asphalt (cutback) adhesive is sufficiently removed use the Sika® MB or Sika® MB EZ Rapid to help promote adhesion to the subfloor or use a SikaLevel® patch/level product in conjunction with the correct primer.
• All moving joints and moving cracks must be honored up through the floor preparation and floor covering installation, finishing with an appropriate Sika flexible sealing compound. Dormant hairline cracks can be covered with Sika® MB or Sika® MB EZ Rapid. Dormant joints and dormant cracks greater than a hairline that will not be honored must be pre-filled in strict accordance with the installation instructions provided by the Sika Technical Service Department.
• SikaBond®-6100 will adhere to most common patching / leveling compounds. Due to differences in asphalt-based adhesive types and performance capabilities, installer must verify that preparation of the surface is sufficient prior to using Sika® MB or SikaLevel® patch / level compound. For unknown substrates, please contact Sika’s Technical Services for best practices at 1-800-933-SIKA.
• All dust, loose and friable material must be completely removed and cleaned with an industrial vacuum from all surfaces before application of the product.

SikaBond®-6100 cleans easily off of most flooring, even after cure. It is still easier to clean as you go while the adhesive is still wet. Clean with a soft non-abrasive towel as you work. After cure remove adhesive with a non-abrasive towel. Tools that will not damage the floor finish may also work. Clean all tools and equipment immediately after use before adhesive cures. Mineral spirits or other similar solvent can be used.
