Kerakoll Keralevel Eco LR fast wall and floor leveling compound (1–25 mm)

Wait 24 hours to tile? Standard levelers set slowly. Ready after 2 hours. Ceramic tiles can be applied. And it works on walls too — thixotropic and fast-setting, it does not slip. This is Kerakoll Keralevel Eco LR.

• Tileable after 2 hours: no schedule delays, no waiting until tomorrow — next trade can start, project moves forward
• Works on walls too: sloped surfaces, shower walls can be leveled — thixotropic and fast-setting, does not slip down
• 25 mm in one layer: no double application, no double waiting — one pass solves thick leveling
• No callbacks: CT-C20-F6 strength (20 N/mm²) — does not crack, does not flake, withstands load
• Qualifies for public procurement: Rating 5 is the highest eco-classification — mandatory in LEED/BREEAM projects, advantage in tenders
• No need for separate product: interior-exterior, wall-floor, plaster-concrete — one material for everywhere
