D737 High-Tack

Universal Flooring Adhesive

Special features

  • for wet lay or dry-lay (pressure sensitive adhesion)
  • can be used over moisture barriers
  • very long open time
  • can be used over cutback mastic

Product Description
STAUF D737 is a highly specialized flooring adhesive that can be used for a wide variety of floor covering, such as: carpet, vinyl, LVP, SVT, LVT, VCT, rubber, etc. It has a great green tack, high final shear and tensile strengths and a very long open time.

STAUF D737 installation methods can vary from a traditional wet lay method, a mid level tacky, and even a drier pressure sensitive type of installation. It can also be used in conventional wet lay on a concrete slab, when installing over existing non-absorbent flooring. STAUF D737 can be applied directly over a wide variety of moisture sealers including 2 part epoxy based sealers.

STAUF D737 is non-hazardous, contains no VOC, is certified as "very low emission" by an independant laboratory and is eligible for LEED points.
Pre-Installation Checklist
A successful installation requires proper preparation of the sub floor. Read and understand all applicable guidelines and technical data sheets before beginning installation. Follow industry standards and flooring manufacturer's recommendations for sub floor moisture content, design, layout and application of flooring materials. All slab constructions must meet the specific requirements of the floor covering to be installed.
Sub Floor Examination
Prior to installation, the sub floor must be checked according to applicable installation guidelines. It must be solid and sound, flat, permanently dry, clean, free of chaps, indentations and anti-adherents, as well as resistant to pressure and tension. Moisture content of all floors must be measured before installation.
Sub Floor Preparation
Depending on type and condition of sub floor, a mechanical treatment (e.g. mechanical brushing, grinding or sanding) may be required. Intensity of such work must be determined at the site by the installer. Dust, paint, residual adhesives or other surface contaminants must be removed by suitable means. Cleaning the surface with an industrial vacuum cleaner is recommended. Cracks and gaps must be filled with concrete crack filler unless they are expansion joints. Level when necessary to 3/16 inches within 10 feet. Heated sub floors must be primed.
Installation Procedure
Spread the adhesive with the appropriate notched trowel. Avoid excessive adhesive thickness by passing the trowel evenly through the adhesive at a 45 degree angle. Observe the appropriate flash time (if applicable). Lay the flooring into the adhesive, correctly position it and press down firmly. Be sure to check the back of the flooring to make certain good adhesive transfer from floor to flooring is accomplished. Roll flooring approx. 15-30 min after installation with a 35-45 kg roller if recommended by the flooring manufacturer. Push down raised edges approx. 30-60 min after installation.
Use Stauf notched trowel #1 (1/16"x1/16"x1/16") for all general installations, except in the following cases:

a) use Stauf notched trowel #2 (1/8"x1/8"x1/16") for installation of all carpets with felt, fiber, jute, action or synthetic backing on porous sub floors.

b) use Stauf notched trowel #9 (1/32"x1/16"x1/32") if thin, non-porous floorings (Sheet Vinyl, VCT, LVT, LVP, SVP or thin Rubber flooring) are installed over non-porous sub floors using the dry-lay or pressure sensitive installation.

c) use Stauf notched trowel #15 (3/32"x3/32"x3/32") to install thick, heavy and/or large flooring tiles as well as heavy sports flooring or thick flooring with heavy traffic on porous sub floors.
When installing non-porous floorings (e.g. VCT, LVT, SVT, PVC, Sheet Vinyl, Rubber, Carpet with foam or PVC backing) over a non-porous sub floor (e.g. speed troweled concrete, epoxy and other moisture barriers, cutback mastic) a dry-lay or pressure sensitive installation method has to be used. The adhesive should be tacky but not transfer to your skin when placing your hand lighty onto the adhesive.
