SMP-925 Poly-Link

Polymer-Based Wood Flooring Adhesive

Special features

  • Moisture cured wood adhesive
  • Non-etching
  • Cleans easily even after cured

Product Description
STAUF SMP-925 Poly-Link is an advanced formula polymer designed for professional wood flooring installation. It replaces isocyanate-containing urethane adhesives. It is ozone and environmentally safe since it contains no solvents or hazardous materials.
SMP-925 has earned the highest GEV-EMICODE EC 1 ranking by the European Association for Control of Emissions for Flooring. See for information. Because there is no water or solvent present, it will not cause dimensional changes to wood flooring. This adhesive is waterproof when fully cured and will not emulsify if it gets wet.
SMP-925 spreads easily and has a non-slump formula that will help insure contact and adhesive transfer. It allows fast installation even with complicated patterns due to its strong green grab and no flash time requirement. Rolling is neither required nor recommended. It offers superior flexibility and is designed to secure flooring, yet allow for normal movement during seasonal changes.
Pre-Installation Checklist
A successful installation requires proper preparation of the subfloor. Read and understand all applicable guidelines and technical data sheets before installation. Follow industry standards and flooring manufacturers' recommendations for subfloor moisture content, design, layout, and application of flooring materials. All flooring material's backing must be solid, sound, and free of anti-adherents. All slab constructions must meet the specific requirements of the floor covering to be installed.
Sub Floor Examination
Prior to installation, the subfloor must be checked according to NWFA installation guidelines. It must be solid and sound, flat, permanently dry, clean, free of chaps, indentations, and anti-adherents, and resistant to pressure and tension. The moisture content of all floors must be measured before installation.
Moisture content in concrete subfloors must be below 3#/24hr/1,000SF using the Calcium Chloride Test or below 75% RH using an in-situ probe per ASTM F1869 and F2170.
All wood floors should have 6-9% moisture content at installation. There should be no more than a 4-5% variance in moisture content between the wood flooring and any wood subfloor. See NWFA guidelines and the wood flooring manufacturer's recommendations for details.
Installation Procedure
Spread the adhesive using the sausage gun. Apply beads approx. ½? thick and 3? apart. Lay the flooring into the adhesive, position correctly, and press down firmly.
When using other than STAUF products in conjunction with STAUF primers, sealers, leveling compounds, or adhesives, STAUF denies any and all responsibility for any ensuing problems and/or damages without prior written authorization from STAUF.
Do not install solid wood below grade. Do not use on concrete with curing agents or sealers. Do not install wood flooring with a moisture reading above 9%. Do not use adhesive as a leveling material. This adhesive will not prevent moisture-related damages to wood flooring caused by flooding, busted pipes, etc., or where moisture conditions are in excess of limitations outlined in the Subfloor Examination.
This adhesive is mold and mildew-resistant and water resistant when fully cured. However, it will not prevent moisture-related damages to wood flooring unless it is used as a moisture barrier (if applicable) within the limitations set forth in the Technical Data Sheet.
In case of an accident, injury, spill, or exposure, see SDS for information. Consult the Technical Data Sheet at for updated information.
