- Subfloor Requirements
- When installing over existing hard surface floors, remove finish to allow a good mechanical bond.
- Subfloor must be sound, smooth, dry and clean: free of dirt, wax, grease, loose paint, or any foreign matter that would interfere with a good bond.
- Complete drying of leveling compounds is critical before installation. While curing time may only take a few hours, the complete drying time of these compounds can take 24 hours or more. Please read manufacturer’s instructions.
- Radiant-heated subfloors - DO NOT USE DriTac 9100. DriTac Flooring Products recommends the use of DriTac 7800, DriTac 7700, DriTac 7600, DriTac 7500, DriTac 7400 or DriTac 7300 wood flooring adhesives when installing wood flooring over radiantheated subfloors.
- If there is a concern about adhesion to any subfloor, install a test area before installing the entire floor.
- Subfloors must be flat to within 3/16” in a 10’ radius or 1/8” within a 6’ radius.
- Remove any high spots with a terrazzo grinder or sander and fill any low spots with a good quality cementitious based latex patch mix.
- Thorough examination for excessive moisture in all subfloors is essential.
- Look around for visible water stains on the drywall and subfloor, particularly on concrete.
- DriTac does not warrant the installation of DriTac adhesives over non-approved concrete sealers and coatings.
- Concrete Subfloors
Concrete should be at least 60 days old. Inspect the concrete before installing flooring over it. First inspect for any wetness at the base of the drywall or for visible signs of moisture on the concrete. Second, test for moisture. Use a Calcium Chloride Method Test or Relative Humidity Test for reliable concrete testing. The results should not exceed 3 lbs., per 1,000 square feet over 24 hours, per the ASTM F1869 Calcium Chloride Method Test, or 75% Relative Humidity (RH), per the ASTM F2170 Relative Humidity Method Test. The maximum reading on concrete for wood installations should not exceed the wood flooring manufacturer’s recommendations. Many wood flooring products can be installed over lightweight concrete (less then 3000 PSI) or gypcrete, providing the surface is properly prepared. Follow the concrete manufacturer’s recommendation for the application of a surface hardener/sealer.
- Wood Installations
- Wood Flooring should acclimate to “live-in” temperature and humidity conditions (please follow manufacturer’s specifications). Job site environment should be at “live-in” conditions at time of installation. Job site environment should be maintained at “live in”conditions at all times
- To start installation, create a starting line and secure a straight edge or backer board at this line.
- Trowel DriTac 9100 adhesive onto the subfloor and lay the wood into the adhesive immediately. Trowel only as much adhesive as you can install wood flooring in 30 minutes. The adhesive will dry faster in drier climates.
- Occasionally check for transfer of adhesive to the back of the wood flooring. If adhesive transfer is less than 90% to the back of the wood flooring, scrape up the adhesive and spread fresh DriTac 9100 Contractors Choice.
- Keep the flooring tight as you install. Install wood against the backer board secured at the starting line. The first five or six rows should be interlocked with releasable or painter’s tape, securing the floor from movement during installation. Continue to use tape TECHNICAL DATA SHEET as necessary. Check with wood manufacturer for list of approved tape manufacturers.
- Allow for expansion in all wood flooring installations. Follow manufacturer’s recommendations.
- Roll the floor with a 100 lb. roller every two to three hours during and immediately after installation.
- When the installation is complete, fill expansion with wedges or cork stripping to hold the floor tightly in place. Remove wedges or cork stripping after floor has set to allow for normal expansion.
- Allow flooring to “breathe”. Do not cover floor with nonporous material such as plastic or vinyl.
- Restrict heavy traffic and furniture placement for 24 hours after installation.
- Allow unfinished wood flooring to acclimate to its new environmental conditions prior to sanding.
- Apply weight to any bowed boards to ensure that the wood flooring adheres securely to the subfloor.
- Clean Up
To remove adhesive from the surface of the wood, use a damp cloth. If the adhesive has already dried on the surface, use mineral spirits to remove. To remove adhesive from tools, clean with water immediately upon completion of installation.
- Ventilation
Installers should provide adequate cross-ventilation during and for 24 hours after installation.
- Keep from Freezing
It is necessary to keep this adhesive from freezing. If the adhesive freezes, it cannot be used.
- Limitations
Adhesive will not prevent moisture-related damage to wood flooring installations. Do not use on wet, contaminated or friable substrates. Due to dimensional stability, only engineered plank wood flooring can be installed below-grade, when proper moisture testing has been conducted and the results do not exceed limitations. After 8 to 12 hours, light traffic is allowed. Do not use as a leveling material. Cutback residue must be removed or encapsulated prior to applying new adhesive.
- Reuse of Partial Containers
Cover adhesive in the pail with a plastic trash bag or two layers of plastic film. Put lid on tightly. Turn over pail. This will seal contents from outside air. To open container, take off lid, cut plastic and remove thin layer of cured adhesive on surface.

Safety & Health
- Precautions
KEEP OUT OF REACH OF CHILDREN. Avoid contact with skin, eyes and clothing. Wash thoroughly after handling. Avoid breathing vapors. Use only with adequate ventilation. Use impervious gloves, eye protection and if TLV is exceeded or if used in a poorly ventilated area, use NIOSH/MSMA approved respiratory protection in accordance with applicable federal, state and local regulations. DO NOT take internally. Empty container may contain hazardous residues.
- First Aid
In case of eye contact, flush thoroughly with water for at least 15 minutes. SEEK IMMEDIATE MEDICAL ATTENTION. In case of skin contact, wash affected areas with soap and water. If irritation persists, SEEK MEDICAL ATTENTION. Remove and wash all contaminated clothing. If inhalation causes physical discomfort, remove to fresh air. If discomfort persists, SEEK MEDICAL ATTENTION.
