With a name
it has to be good

SL C955 ADVANCED is a high performance smoothing compound that doesn’t require intensive subfloor preparation – saving you both time and money!

With exceptional flow characteristics, it can be applied directly to most common substrates without priming, including old adhesive residues, ceramic tiles, Bostik damp proof membranes, flooring grade plywood, and resin flooring.

It’s unaffected by moisture, meaning it can be used over damp subfloors, and can be applied from 2mm to 30mm in a single application when bulked out with a suitable aggregate.
