Koster SL Premium – Basement Floor Self Levelling
Koster SL Premium is a high performance self levelling flooring compound for use in demanding basement waterproofing applications.
It’s a high quality, fast setting underlayment that hardens tension free and provides a smooth, level surface ready to receive subsequent flooring systems.
Unlike latex based self levelling systems, SL Premium can be used on damp and moist slabs prior to the installation of a waterproofing system.
Koster SL Premium is ideal to level depressions in a slab prior to the installation of a cavity drainage membrane. Following a flood test of the slab.
Can be used to provide a stable, trafficable surface over a slurry waterproofing layer such as Koster NB1 Grey.
Can be applied between 5mm and 15mm.
Consumption Approx. 1.5 kg / m2 per mm layer thickness
