SikaBond®-5800

LEED v4.1 & LEED v5 California Department of Public Health (CDPH) Standard Method v1.2

Acrylic polymer

24 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 and freezing at temperatures between 41°F and 77°F (5°C and 25°C). If frozen, discard.

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

~7.68 lbs/gal (~0.92 kg/L)

Room temperature between 65°F (18°C) and 95°F (35°C). For ambient temperatures standard construction guidelines should be followed. Follow all floor covering manufacture’s acclimation and room temperature requirements.

Between 35% and 65% during installation is best for adhesive. See floor covering manufacturer for floor covering requirements.

During laying and until SikaBond®-5800 has fully cured, the substrate temperature must be between 65°F and 95°F (18°C and 35°C). Radiant heated subfloors must be turned off 48 hours prior to, during and after installation to prevent premature curing of the adhesive. For substrate temperatures, standard construction guidelines should be followed.

Concrete moisture vapor emission rate (MVER) may not exceed 12 lbs. per 1,000 sq.ft. (5.44 kg per 92.9 m²) per 24 hours (using an anhydrous calcium chloride test ASTM F1869). Do not install when the relative humidity (RH) of the concrete slab exceeds 99% (using ASTM F2170) (or 5 lbs./80% RH prior to install vinyl sheet goods).

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

Floor may accept light foot traffic after ~8 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.

0–60 minutes (depending on laying method and porosity)

~15 minutes - up to 3 hours (depending on laying method and porosity; the adhesive layer must remain dust and dirt free)

• 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®-5800. Floors installed with SikaBond®-5800 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 compression 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®-5800 must be mechanically removed, as per ASTM F710.

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

• SikaBond®-5800 can be used on properly prepared, structurally sound concrete, cementitious patch/underlayments, lightweight
  concrete/gypcrete (coated with appropriate primer as per ASTM F2419), APA rated plywood (exterior or underlayment grade), existing vinyl tile flooring, terrazzo, underlayment grade OSB, existing fully adhered non-cushioned sheet vinyl. 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.
• 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. All moisture tests must be documented prior to installation for Sika warranty to be in effect. For on-grade subfloors Sika recommends the use of Sika® MB, Sika® MB Redline or Sika® MB EZ Rapid (see appropriate product data sheet for installation instructions and proper details; treat Sika® MB products as a non-porous substrate and if using SikaBond®-5800 directly over Sika® MB products, allow adequate time for SikaBond®-5800 to “flash-off” prior to the installation of the floor covering) for best protection against subfloor moisture. Moisture in wood subfloors must be measure with a wood moisture meter. The moisture content must not exceed 12%.
• Preparation is a critical step in the installation process and will ensure a successful long term tenacious bond.
• Concrete substrate must have a concrete surface profile of CSP 1-3.
• 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.
• Subfloors must be flat to 3/16” in a 10’ radius or 1/8” within a 6’ radius. Remove any high spots by mechanical means and fill any low spots with a SikaLevel® patch/level product in conjunction with the correct primert.
• When using new sheet vinyl as a moisture barrier over concrete, a vinyl primer must be applied. Refer to manufacturer’s instructions and limitations. 
• When installing floor covering over gypsum based substrate, the gypsum must first be sealed/primed (as per ASTM F2419) and allowed to dry prior to installation of floor covering (see gypsum manufacturer’s instructions for recommended sealer/primer).
• For substrates with old well bonded non-water soluble adhesive or adhesive residue use Sika® MB, Sika® MB Redline 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, Sika® MB Redline 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.
• To produce an absorbent, even subfloor, a cement based SikaLevel® levelling compound shall be used. For appropriate layer thicknesses refer to the relevant valid data sheets.
• SikaBond®-5800 will adhere to most common patching / levelling 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.

Wet adhesive can be removed with a damp cloth. Dry SikaBond®-5800 can be removed with mineral spirits or similar cleaning solvents. To remove adhesive from tools, clean with water immediately upon completion of installation.
