Alcohol based Primer

Special features

  • use prior to WFR-930
  • creates dust-free surface
  • will increase spread rate
  • dries within 1/2 hour

Product Description
SOP-230 is a solvent based primer created for a dust free installation and better adhesion of Stauf WFR-930 adhesive. SOP-230 penetrates deep and leaves a rough texture to assist in adhesion between adhesive and surface to be applied. Spreads easily and creates an evenly absorbent surface ready for installation of flooring. It has superior coverage and dries very quickly.
Pre-Installation Checklist
A successful installation requires proper preparation of the sub floor. Read and understand all applicable guidelines and technical data sheets before 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, permanently dry, clean, free of chaps 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 3#/24h/1,000 sq. ft. using the Calcium Chloride Test or below 75% RH using an in-situ probe per ASTM F1869 and F2170.

Sub Floor Preparation
The condition of the sub floor will determine which type of mechanical treatment is required (e.g. wire brushing, sanding, grinding or shot blasting). Dust, paint, curing compounds, sealers, residual adhesives or other surface pollutants MUST be removed by suitable means. Extent of sub floor preparation can only be determined at the site by the installer. Clean the surface with an industrial vacuum cleaner, tack or damp mop floor before application. Do not use sweeping compounds as most will contain oil or wax which will act as an anti-adherent and prevent primers, sealers, leveling compounds, coatings and/or adhesives from bonding to the concrete. Cracks and gaps must be treated prior to application of primers, sealers, leveling compounds, coatings and/or adhesives (for details see Technical Information #19 @
Installation Procedure
Shake can before use and apply primer undiluted with brush or foam roller. Avoid pudddles as they prolong the drying period. Apply primer once and not too thick. On poorly absorbent sub floors the primer must be applied sparingly; do not leave a visible layer of primer on the floor. Once dried, the primer is transparent. Higher temperatures will speed up the drying process.
Flammable. UN 1263 paint related materials, DOT class 3. Observe official regulations on storage and handling of flammable liquids (red labels).
