Description

Isocrete Screedfast is a specially formulated cement giving a high early strength and very rapid drying screed. It is used in different mix designs with water and 0/4 (MP) grade sands to provide Screedfast 1000 and Screedfast 2000.

Mix:

  • Screedfast 1000: 1:4 mix (by volume) of Screedfast cement and 0/4 mm (MP) category 1 sand. When laid Screedfast 1000 will give a Category B screed and will dry to 75% RH in 3 to 4 days at 20°C.
  • Screedfast 2000: 1:3 mix (by volume) of Screedfast cement and 0/4 mm (MP) category 1 sand. When laid Screedfast 2000 will give a Category A screed and will dry to 75% RH in 24 hours at 20°C.

Screed thickness:

  • Bonded: Minimum 15 mm laid bonded with Isocrete M-Bond Extra epoxy resin bonding agent. Minimum 30 mm laid onto Isocrete Polymer 70 primer and grout.
  • Floating: Minimum 75 mm (65 mm domestic).
  • Unbonded: Minimum 50 mm.
