Product description
WULFF SA 50 Plus is a premium cementitious self-levelling compound for top-grade smoothing and preparation of interior floors prior to installation of all textile and resilient coverings, linoleum, PVC, demanding LVT vinyl planks and ceramic.
It is characterised by extremely low internal stresses and superior flow capability ahead of the trowel — the compound finds the level on its own, not the installer. The result is a smooth, even substrate without cracks or hollow spots.
Compliant with the highest flatness classes E1–E4. No maturing time — work immediately after mixing; faster sanding and floor laying already after 24 h.
