Isowarm Tackerboard System - Isocrete K-Screed (Upper floor)

Isocrete K-Screed is semi-dry cementitious and incorporates proprietary additives to produce early drying and high strength.

Standard K-Screed and Heavy Duty K-Screed may be laid bonded, unbonded or floating (for weight saving and thermal or sound insulation) and may be used with proprietary underfloor heating systems.

• Bonded: Minimum 15 mm laid bonded with Isocrete M-Bond Extra epoxy resin bonding agent. Minimum 20 mm laid onto Isocrete Polymer 70 primer and grout.

• Floating (reinforced screed): Minimum 75 mm (65 mm domestic) but can be less (40 mm) on 5 mm acoustic insulation.

• Unbonded (reinforced screed): Minimum 40 mm.

Thickness (Heavy Duty Isocrete K):

• Bonded: Minimum 30 mm laid bonded with Isocrete M-Bond Extra epoxy resin bonding agent. Minimum 40 mm laid onto Isocrete Polymer 70 primer and grout.

• Floating (reinforced screed): Generally 75 mm (65 mm domestic) but can be less (40 mm) on 5 mm acoustic insulation.
