Cementitious Self-Levelling Floor Topping

One-component polymer modified cementitious self-levelling screed for concrete floors and floor coverings.

  • Free-flowing self-levelling compound
  • Pumpable through standard equipment
  • Minimal shrinkage and crack resistance
  • High early strength for quick turnaround

Surface Preparation

Cementitious surfaces should be sound, clean and free of loose materials. Floors must be solid and concrete should be cured for 28 days

Priming

Prime the surface before application with Builda Latex SBR Bond. Remove excess primer and apply within 24 hours of primer application

Mixing

Add one 25 kg bag to about 5 L clean cold water and mix for 3-4 minutes at 400-500 rpm until smooth. Do not exceed 6 L water per bag

Application

Apply as self-levelling floor topping to prepared and primed substrate following recommended placement procedure

  • Unlevel floors
  • Interior sound concrete sub-surfaces
  • Old floors with cut back adhesive
  • Floors prior to carpeting or vinyl flooring
  • Wood, plywood, steel and structurally sound floor surfaces
