Sopro Rapidur FE 678 - Levelling Screed

Application

For production of self-levelling, rapid-set cement screeds to DIN 18560 allowing early flooring installation. For heated screeds, bonded screeds and unbonded screeds (on separating or insulation layer). Unbonded construction with separating layer is recommended on mastic asphalt screeds. Suitable for a wide range of thin coat heating systems. For indoor use only.

  • Coat thickness for bonded screeds: 20–70 mm.
  • Coat thickness for insulation or unbonded screeds: 35–70 mm.

Suitable primers:

Substrates may be pre-treated with Sopro HE 449 bonding emulsion for wet-on-wet placing of screed or with Sopro GD 749 primer.

Description

A polymer-modified, ready-to-use dry mix for production of rapid-set self-levelling screed allowing early flooring installation. Grade CT-C25-F5 to DIN EN 13813.
