Product Description:

SUPER FLO-TOP is a single-component, cement based, free-flowing, self-leveling compound specially designed for easy application over concrete floors as an underlayment for subsequent placement of floor coverings. It is suitable for use as a repair and leveling course and may be applied at thicknesses from featheredge to 1" (25 mm) neat. SUPER FLO-TOP may be used as a light-duty (foot traffic only) wearing surface, when protected by a Euclid Chemical epoxy/urethane system.

Primary ApplicationS:

  • Leveling interior or exterior (see precautions/limitations) sound concrete surfaces
  • Leveling wood subfloors
  • Over radiant heat systems
  • Light duty wearing surface

Features / Benefits:

  • Fluid consistency for self-leveling applications
  • Pumpable through standard equipment
  • Self-leveling for smooth, flat floors
  • High early strength for early turnaround
  • Excellent bond strength
  • Excellent self-healing properties
