Description:

KÖSTER SL Premium is a high quality, fast setting underlayment that hardens tension free and provides a smooth, level surface ready to receive subsequent flooring systems. It hardens within hours to a smooth, strong, and multifunctional leveling layer. It may be applied onto a variety of substrates such as KÖSTER
VAP I 2000 coatings, concrete, etc. KÖSTER SL Premium accepts all major floor coverings and is compatible with most adhesives. It is resistant to abrasion and wear. If the material is installed onto smooth,
non-absorbent substrates such as KÖSTER VAP I 2000 coatings, the substrate must be primed with KÖSTER VAP I 06 Primer. KÖSTER SL Premium can be applied in layer thicknesses between 5 and 15 mm, can be feathered out to 2 mm, and installed in depressions up to 30 mm.It cures quickly and crack-free with up to 90% reduced shrinkage.
KÖSTER SL Premium has a high surface hardness and a very good bond strength to the substrate. KÖSTER SL Premium is not a decorative top coat, but is suitable as a low-wear wearing layer in cellars or storage rooms.

Fields of  Application:

KÖSTER SL Premium is designed for leveling uneven concrete surfaces as well as for surfaces covered with KÖSTER VAP I 2000 vapor barriers. It is intended for interior use.
