Product Description
STAUF SMP-960 One-Step is an advanced formula, unique polymer 3-in-1 adhesive designed for professional wood flooring installation. It replaces isocyanate-containing urethane adhesives which can etch flooring surfaces. It is ozone and environmentally safe since it has no solvents or other hazardous materials. It is certified 'green'. And it meets ASTM standards for sound and impact noise control. Long open time allows for easy installations. No rolling is required. Since there is no water or solvent present, it will not cause dimensional changes to wood flooring. SMP-960 offers superior flexibility and moisture-retarding capability.
The adhesive spreads easily and has a non-slump formula that will help insure contact and adhesive transfer because the ridges will bridge normal gaps between the flooring and sub floor. It allows fast installation even with complicated patterns due to its strong green grab. There is no flash time required, so installation can commence immediately. Rolling is neither required nor recommended. It offers superior flexibility and is designed to keep the flooring in place, yet allow for normal movement during seasonal changes to the flooring.
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 starting, the sub floor 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, as well as resistant to pressure and tension. Moisture content of all floors must be measured before installation.
Moisture content in concrete sub floors must be below 12#/24h/1,000 sq. ft. using the Calcium Chloride Test.
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 sub floor. See NWFA guidelines and the wood flooring manufacturer's recommendations for details.
Sub Floor Preparation
Depending on type and condition of sub floor, a mechanical treatment (e.g. mechanical brushing, grinding or sanding) is required. Intensity of such work must be determined at the site by the installer. Dust, paint, residual adhesives or other surface pollution must be removed by suitable means. We recommend cleaning the surface with an industrial vacuum cleaner. Cracks and gaps must be filled with concrete crack filler CCF-30, 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. There is no flash time, so installation should begin immediately. Lay the flooring into the adhesive, correctly position it and press down firmly. Rolling is neither required nor recommended. Be sure to check the boards at regular intervals to make certain good adhesive transfer from floor to flooring is accomplished.
When using other than Stauf products in combination with Stauf sealers, we deny any and all responsibility for any ensuing problems and/or damages without prior written permission from Stauf.
Do not install solid wood below grade. Do not use on concrete with curing agents or sealers except approved Sealers listed below. Do not use on damp sub floors. 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 where moisture conditions are in excess of limitations outlined in Installation Procedure.
In case of accident, injury, spill or exposure, see MSDS sheet for information. Consult technical data sheet at for updated information.
