Ambient Air Temperature
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.
Relative Air Humidity
Between 35% and 65% during installation is best for adhesive. See floor covering manufacturer for floor covering requirements.
Substrate Temperature
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.
Substrate Moisture Content
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.

Curing times depend on environmental and subfloor conditions, adhesive layer thickness and floor covering type.
Flash-off Time
0–60 minutes (depending on laying method and porosity)
Application Time
~15 minutes - up to 3 hours (depending on laying method and porosity; the adhesive layer must remain dust and dirt free)
Coverage
- 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.
NOTES ON 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.
SUBSTRATE QUALITY
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.
SUBSTRATE PREPARATION
- 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.
CLEANING OF TOOLS
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.
FAQ
SikaBond®-5800 has a shelf life of 24 months when stored in its original, unopened packaging. It should be kept in dry conditions and stored between 41°F (+5°C) and 77°F (+25°C) to ensure maximum effectiveness. Avoid exposing the adhesive to freezing temperatures during transport and storage, even though it is freeze-thaw stable per ASTM D-7149.
SikaBond®-5800 has high moisture resistance and can be used on below-grade subfloors if moisture levels are within acceptable limits. However, it does not act as a moisture barrier. For concrete subfloors with excessive moisture, it is crucial to use a vapor barrier in accordance with the flooring manufacturer's recommendations. Always test for moisture levels and consult the manufacturer if you're unsure about using it in moisture-prone areas.
The waiting time before walking on the floor depends on the type of flooring and installation method. For most installations, including LVT, LVP, and vinyl sheet goods, you should allow at least 8 hours before allowing foot traffic if using a wet-lay method. For pressure-sensitive applications, traffic can begin immediately after installation, but it is recommended to avoid heavy traffic for at least 24 hours to allow the adhesive to set properly.
SikaBond-5800 is a high-performance, polyurethane-based resilient flooring adhesive used for bonding to a wide range of materials, including wood, metal, ceramic, concrete, and various types of plastic. It is commonly used in construction, flooring, and DIY applications where strong and durable adhesion is needed.
The maximum allowable moisture level in concrete subfloors is 12 lbs. per 1,000 square feet over 24 hours (measured using the ASTM F1869 Calcium Chloride Method Test) and up to 99% relative humidity (RH) (measured using the ASTM F2170 Relative Humidity Test). For vinyl sheet goods, the moisture level must not exceed 5 lbs. per 1,000 square feet over 24 hours.
If the adhesive dries too quickly, it may not bond properly. Ensure you are applying the adhesive in the recommended temperature and humidity conditions (65°F to 95°F and 35%-65% RH). For certain flooring types, such as LVT or LVP, you can use SikaBond®-5800 either as a wet adhesive (allowing a 10-15 minute flash-off time) or as a pressure-sensitive adhesive (dry to a tacky state). Ensure that you are working within the time frame before the adhesive becomes too dry for proper bonding.
No, SikaBond®-5800 is compatible with approved subfloors such as A.P.A. Rated Plywood, concrete, terrazzo, existing vinyl tile flooring, underlayment grade OSB, and lightweight concrete or gypcrete. It is not approved for use over ceramic tile or certain non-porous surfaces Always check with the flooring manufacturer for recommendations and ensure the subfloor is clean, smooth, dry, and free from contaminants.
SikaBond®-5800 is suitable for installing a variety of resilient flooring types, including Luxury Vinyl Tile (LVT), Luxury Vinyl Plank (LVP), carpet tile, rubber flooring, cork/rubber/foam underlayment, fiberglass-backed sheet vinyl, and cork tiles.
