RLC-580 Fiber Level

Fiber reinforced Hydrolyzed Anhydrite Self Leveling Compound

Special features

  • levels up to 3" thick by itself
  • forms flat and even surface by itself
  • can be used over any interior subfloor

Product Description
STAUF RLC-580 is a leveling compound based on Hydrolyzed Anhydrite formulated specifically for use over old adhesive or flooring remnants that still remain embedded in the concrete after the old flooring has been removed. It is very forgiving of any foreign objects that are still intact and stuck to the floor and may be used directly over them.

It forms a flat, even, level surface and may be used to level up to 3? thick variances.
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 applicable installation guidelines. It must be solid and sound, permanently dry, clean, free of chaps 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.
Sub Floor Preparation
The condition of the subfloor 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 contaminants MUST be removed and a porous surface achieved by suitable means. The extent of subfloor preparation can only be determined at the site by the installer. Clean the surface with an industrial vacuum cleaner and tack the floor with a damp microfiber mop before application. Do not use sweeping compounds unless they are water-based as most others 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 @ www.staufusa.com).
Apply suitable primer or sealer to the subfloor before spreading cement or gypsum-based leveling compounds to increase the bond.
Mixing of Components
Fill the correct amount of cold water into a bucket. Wear a proper dust mask when using powdered products in enclosed areas. While stirring add powder to the water and continue stirring until an even mixture is formed. Use an electric mixer with 600 to 800 rpm. Stir for two more minutes, wait one minute and stir again for one minute.
Installation Procedure
Spread the leveling compound within approx. 20 min. Do not pour the compound in one spot but evenly over the entire (approx. 6x6 ft.) area to be covered. The self-leveling compound does not need to be leveled mechanically and forms an even surface by itself. Protect the leveling compound from direct sunlight and draft during drying.
Limitations
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.
