Technical Data for Sopro FAS 551 – Fibre Reinforced Self-Levelling Filler
| Suitable Substrates | Old, rigid timber flooring, wood floorboards, grade V 100 G particleboard to DIN 68763 |
| Coat Thickness | Not extended: 3 – 20 mm Extended: for coat thickness upwards of 20 mm, can be extended using 0 – 4 mm graded silica sand (e.g. Sopro EEK 871 epoxy screed aggregate) by up to approx. 1/3 of prepared compound volume |
| Mixing Ratio | Approx. 6.5 ltr water : 25 kg Sopro FAS 551 Take care to ensure exact proportioning of water |
| Flow table value | 24.5 – 25.5 cm (Vicat ring to DIN 1164; size: internal diameter 65 mm at top and 75 mm at bottom, height 40 mm; on suitable, dry, clean glass plate) |
| Compressive Strength (28 days) | C30 |
| Flexural Strength (28 days) | F7 |
| Working life | 20–30 minutes |
| Walkable | After approx. 2 hours |
| Ready to receive floor covering | Ready to receive ceramics and cast stone after 2 – 3 hours; natural stone after 24 hours. For elastic, textile, laminate, parquet and wood block floor coverings, maximum permissible moisture content (≤ 1.8% CM) must be confirmed by CM measurement over full screed cross-section prior to flooring installation. Empirical values for achievement of this – in the function of filler coat thickness, subject to application to dry substrate – are as follows:
– 3 – 5 mm coat thickness: after approx. 1 day |
| Application temperature | From +5°C to +25°C (substrate, air, material) |
| Coverage | Approx. 1.6 kg/m² per mm coat thickness |
| Shelf Life | Approx. 6 months, subject to storage on pallet in dry conditions in original containers |
| Use | Indoor only |
| Reaction To Fire | Class A2fl -1 |
| Apparent density | Approx. 1.8 kg/dm³ |
*Based on DGNB (German Sustainable Building Council) criterion “ENV1.2 Local Environmental Impact” (2015 version).
Available in 25kg bags, 42 bags per pallet
