SUPERCAP™ FAST
TM SUPERCAP™ FAST
Advanced Self-Leveling Underlayment Technology
Description SUPERCAP FAST is a pumpable and pourable, cement-based, advanced self-leveling underlayment based on a
proprietary mineral binder system that develops high early strength and is used to finish concrete and level uneven
SUPERCAP
floor surfaces. Finished flooring can be installed quickly. Apply it over concrete, wood and other types of sound, rigid
flooring before installing wood, resilient, cork, sports, ceramic, stone, carpet or other flooring systems. Floor covering
adhesives that are suitable for concrete can be used on SUPERCAP FAST.
Where to Use Location: ▪ Interior
Substrates: ▪ Concrete
▪ Wood
▪ Rigid subflooring including VAT, VCT and ceramic tile
Applications: ▪ New concrete
▪ Deteriorated and uneven surfaces – deflection
▪ Restoration
Advantages • Eliminates the need for power troweling concrete.
• Can be installed over newly poured concrete as soon as five days after placement.
• Finished floor goods may be installed as soon as 1 day after application, subject to thickness, drying conditions and
type of flooring materials.
• Eligible for two (2) LEED® project points for regional materials.
• Low pH formulation allows for quick installation of finished floor goods.
• Water damage stable; will not deteriorate, warp, buckle, or change shape even when soaked or exposed to high
moisture conditions.
• Surface is walkable in 2-4 hours and may be open to wheel traffic within 24 hours.
• Can be left open to normal trade’s traffic for up to 1 year prior to installation of floor coverings.
• Inorganic formulation will not contribute to or harbor growth of mold or mildew.
• Will not contribute to secondary emissions or irritating fumes upon setting or curing.

All test methods and procedures are described in “Testing Hydraulic Characteristics of SUPERCAP”; a document that is available upon request.
*Mix water demand may vary due to regional raw materials where SUPERCAP is manufactured and may cause slight variations in physical properties.
How to Use New Concrete Slabs: Bull float to FF of 12-15, adjust finished elevation by ⅝" for 2-course slab; curing compounds are
not recommended. New concrete should be allowed to cure for a minimum of 5 days prior to installation of SUPERCAP.
Concrete must be free from hydrostatic pressure.
Concrete Floors (general): Substrate must be well-bonded (ICRI Technical Guideline No. 03739) and completely clean;
free of oil, wax, grease, sealers, curing compounds, asphalt, paint, dirt, loose surface material and any contaminate that
will act as a bond-breaker. Surface bond strength of substrate should be minimum 100 psi (0.69 MPa). Weak concrete
surfaces must be cleaned down to solid sound concrete by mechanical means. Acid etching or chemical cleaning is not
acceptable. Expansion joints in the concrete substrate must be reflected through the applied layer SUPERCAP. Concrete
must be free from hydrostatic pressure. Fill deep areas and depressions with a SUPERCAP pre-fill or suitable cement-
based concrete repair product. Repair cracks with epoxy grout. Material will flow as water and will go anywhere water
will go (contact Product Technologies’ Technical Service Department for details).
Over Cutback and Adhesive Residue: Supercap can be installed over non-soluble adhesives residues such as Cutback.
Cutback adhesives may contain asbestos fibers whose inhalation resulting from sanding or grinding maybe harmful.
Thick accumulation, brittle, powdery residue or weak unbonded adhesive must be removed using the wet-scrape and
wet-sweep method as outlined in the Resilient Floor Covering Institute www.rfci.com booklet. Consult your local,
provincial and federal regulations before attempting to remove or dispose of hazardous material for further
instructions. Remaining residue needs to be translucent, clean and well bonded to the substrate readied for SUPERCAP
PRIMER. Installation over non-Cutback adhesives is possible provided the residue is solid, bonded to substrate and NOT
water soluble. Avoid applications where heat may soften the adhesive causing de-lamination.
Water Soluble Adhesive: Mechanically remove by shotblasting or other acceptable mechanical means leaving a
Concrete Surface Profile (ICRI CSP) 3-5. Other surface contaminates may also require mechanical removal.
