SikaBond®-6200

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).

Concrete moisture vapor emission rate (MVER) may not exceed 3 lbs. per 1,000 sq.ft. (1.36 kg per 92.9 m²) per 24 hours, anhydrous calcium chloride test (ASTM F1869). Do not install when the relative humidity (RH) of the concrete slab exceeds 75% (ASTM F2170).

For protection of the floor covering, follow the floor covering manufacturer’s requirements for subfloor moisture. 

Floor may accept light foot traffic after 8–12 hours

Restrict heavy traffic and furniture placement for ~24 hours after installation

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

• These are estimated spread rate coverages and additional adhesive may be required based on substrate porosity/profile/levelness, wastage or any other variations. Apply product 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®-6200. Floors installed with SikaBond®-6200 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.

SikaBond®-6200 spreads very easily. Expect little or no “grab” from the adhesive initially. As SikaBond®-6200 dries, it becomes increasingly tacky, ultimately producing a very aggressive grab. Working installation time is several hours. Keep the adhesive surface clean of dust, dirt or anything that may hinder a good bond. The time it take SikaBond®-6200 to attain its aggressive grab will differ with temperature, humidity, moisture content of the subfloor and the trowel size used. At 70°F (21°C) and 50% humidity it will take approx. 45 minutes to one hour for SikaBond®-6200 to become tacky. Fans can be used to create air flow and speed up drying time. Do not allow construction dust to settle on the adhesives surface.

Substrate must be clean and dry, homogeneous, even, free from oil, grease, dust and loose particles. Paint, laitance and other poorly adhering particles must be removed by mechanical means.

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

• SikaBond®-6200 can be used on properly prepared, structurally sound concrete, lightweight concrete (coated), cementitious patch/underlayments, plywood, APA standard underlayment particle board with latex primer, existing fully adhered non-cushioned sheet vinyl, terrazzo, existing vinyl tile flooring, underlayment grade OSB. All floor covering manufacturer’s recommendations must be followed.
• Concrete substrate must have a concrete surface profile of CSP 1-3.
• Thorough examination for excessive moisture in all subfloors is essential. Look around for visible water stains on the drywall and subfloor, particularly on concrete. Checking for and avoiding excessive moisture in every subfloor must be done. Sika requires the use of moisture tests on all concrete and wood subfloors. It is important that the subfloor’s moisture content do not exceed the flooring manufacturer’s or Sika’s recommendations, whichever is lowest. If excessive moisture is present use an appropriate vapor barrier. All moisture tests must be documented prior to installation for Sika warranty to be in effect. After moisture testing of the concrete subfloor is complete, if moisture is above limitations, a Concrete Moisture Control System is required. The ASTM F1869 Calcium Chloride Test measures moisture emission in concrete. Moisture in wood subfloors should be measure with a wood moisture meter. The moisture content should not exceed 12%. Subfloors should be within 5% of the wood flooring’s moisture content. Read flooring manufacturer’s moisture standards. A moisture meter can also be used to measure moisture in concrete. Follow the flooring manufacturer’s instructions carefully. Moisture meters measure wood and concrete differently.
• Below grade applications are generally not recommended unless proper precautions are taken to protect the floor covering from subfloor and in-room humidity extremes.
• The subfloor must meet the requirements of national standards, must have good compression and tensile strength.
• Preparation is a critical step in the installation process and will ensure a successful long term tenacious bond.
• 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. Thoroughly clean with an industrial vacuum. Remove laitance or weak areas mechanically and thoroughly.
• When installing over existing hard surface floors, remove finish to allow a good mechanical bond.
• When installing floor covering over gypsum based substrate, the gypsum must first be sealed/primed and allowed to dry prior to installation of floor covering (see gypsum manufacturer’s instructions for recommended sealer/primer).
• Epoxy and poured vapor barriers may leave an oily residue after application, which should be removed. The vapor barrier’s surface should be abraded or lightly sanded and cleaned thoroughly.
• When using new sheet vinyl as a moisture barrier over concrete, a vinyl primer must be applied. Refer to manufacturer’s instructions and limitations. 
• Subfloors must be flat 3/16” in a 10’ radius of 1/8” within a 6’ radius. Remove any high spots with a grinder or sander and fill any low spots with a Sika® Level patch/level product in conjunction with the correct primert.
• 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 a Sika® Level patch/level product in conjunction with the correct primer.
• SikaBond®-6200 will adhere to most common patching / levelling compounds. Due to differences in asphalt-based adhesive types and performance capabilities, inataller must verify that preparation of the surface is sufficient prior to using Sika® Level patch / level compound. For unknown substrates, please contact Sika® Technical Services for best practices at 1-800-933-SIKA.

Wet adhesive can be removed with a damp cloth. Dry SikaBond®-6200 can be removed with mineral spirits or similar cleaning solvents. To remove adhesive from tools, clean with water immediately upon completion of installation.
