Description

A special polymer-modified binder for use in rapid-set cement screeds allowing early flooring installation, based on DIN 18 560. Low-chromate to Regulation 1907/2006/EC, Annex XVII.

Features and benefits:

Ready for tiling after only approximately three days.
For fast-track or tightly scheduled screed laying.
Suitable for floor heating systems.
Good workability.
Pumpable.
Tested to CT-C60-F7 DIN EN 13813.
Floor heating system: Suitable (maximum flow temperature: +55°C).

Mixing ratio:

1:4: 25 kg Sopro Rapidur® B5 : 100 kg 0–8 mm screed sand to DIN EN 12 620 (15 shovelfuls) : 7.5–8.5 L water (depending on sand moisture and mortar consistency). w/c ratio 0.30–0.34.
1:5: 25 kg Sopro Rapidur® B5 : 125 kg 0–8 mm screed sand to DIN EN 12 620 (20 shovelfuls) : 9.0–10.0 L water (depending on sand moisture and mortar consistency). w/c ratio 0.36–0.40.

Particle distribution (grading curve) for aggregate (screed sand) shall fall within A8/B8 range under DIN 1045 Part 2, Annex L, Diagram L.1, and shall exhibit an adequate, though not overly high proportion of fine sand; percentage passing a 0.25 mm sieve: approx. 7–10 %.

Coverage:

Mixing ratio 1:4: Approximately 4.0 kg/m² per cm thickness.
Mixing ratio 1:5: Approximately 3.5 kg/m² per cm thickness.

Strength class:

- Mixing ratio 1:4:

CT-C20-F4 after one day.
CT-C35-F5 after three days.
CT-C45-F5 after five days.
CT-C60-F7 after 28 days.

- Mixing ratio 1:5:

CT-C16-F3 after one day.
CT-C25-F4 after three days.
CT-C30-F4 after five days.
CT-C45-F7 after 28 days.

Specification data - Polymer-modified levelling screed mixes

Colour	Cement grey.
Thickness	Maximum and minimum screed thickness depends on incorporated aggregate. Screed should be at least three times and at most ten times as thick as maximum particle diameter of aggregate. Recommended grading of screed aggregate 0–8 mm; coat thickness approximately 25–80 mm.
Pot life	2–3 hours (approximately). Guidance for specification option: Stiffened mortar must not be retempered by addition of water or fresh mortar to restore workability.
Drying time	Walkable: After 7–8 hours; Ready to receive floor covering: For tiling: after approx. three days; for impervious coverings: after 3–5 days and after achievement of residual moisture content ≤1.8% CM.
Application temperature	5–25°C.
Minimum thickness	Floor heating systems, 25 mm pipe cover.
Suitability for castor chairs	Suitable (for castors to DIN 68131). Manufacturer guidance (Castor chair resistance)
