Self-Levelling Compound Pumpable (SLC P) Fast-Track Self-Levelling Screed. a.b.e.®screed SLC P is a single pack, rapid hardening cement-based screed for levelling floors where the quick setting is essential. a.b.e.®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. 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.
