Self-Levelling Compound Pumpable (SLC P) Fast-Track Self-Levelling Screed. abe.®screed SLC P
is a single pack, rapid hardening cement-based screed for levelling floors where the quick setting is essential. abe.®screed SLC P
can be hand applied by trowel (0 – 20 mm) or can be pumped (4 – 20 mm). For pumped applications, an 8 mm average thickness would be a typical expectation on a reasonably level base. For fast track refurbishment and new construction where finishes such as carpets, ceramic tiles, vinyl, woodblock or cork need to be applied quickly. Self-Levelling Screed is used for smoothing floors in office buildings, dwellings, shops, public buildings, schools, hospitals and airports where a fast track, smooth underlay is required for the above finishes.
Advantages of Self-Levelling Screed:
- Quick setting
- Can be pumped up to 2 000 m² per day, under suitable conditions
- Walk on after 6 – 8 hours @ 25 °C under normal conditions
- Can normally apply coverings onto a 10 mm thick screed after 24 hours
- Pumpable or hand laid
- Single pack just add water
- Protein free, will not harbour bacteria
The base slab or screed should be sound with a minimum thickness of 40 mm and with a minimum compressive strength of 25 MPa. The surface must also provide a minimum tensile adhesion strength of 1.5 MPa. All surfaces must be clean, mechanically sound and free of laitance, dust, grease and oil. Vacuum abrasive blast cleaning is the preferred method of surface preparation.
Wet grinding followed by vacuuming may also be used.
