Sopro Floor WS 3.50 Self-Levelling Compound 3-50mm 25kg

Sopro Floor WS 3.50 is a rapid-setting, cement-based self-levelling floor compound for creating perfectly smooth and level subfloors before installing ceramic tiles, natural stone, vinyl, carpet, laminate, timber flooring and resin floor systems.

Developed with Mikrodur micro-cement technology, it delivers outstanding strength, excellent workability and rapid drying, which suits both residential and commercial projects. The compound flows out and self-smooths, and can be mixed and laid by hand or pumped by machine for fast floor preparation over larger areas.

Key benefits:

• Layer thickness from 3 to 50 mm in one pour
• Walkable after approx. 2 hours
• Ready for ceramic tiles after approx. 12 hours
• High compressive strength (30 N/mm²) - class CT-C30-F6 to EN 13813
• Excellent flow and self-smoothing properties
• Pump or manual application

Application: the substrate must be clean, dry, stable and free from dust, grease and loose particles. Prime absorbent substrates first - a deep penetrating primer like Cekol DL-80 stops the substrate pulling water out of the compound. Mix with clean water following the bag instructions, pour or pump, spread with a smoothing trowel or gauge rake and go over it with a spiked roller to release trapped air.

Once cured, the floor is ready for virtually any finish. For tiling, pair it with Sopro S-Flex gel tile adhesive and Atlas Elastic Grout, and in showers and wet rooms waterproof first with the Sopro tanking kit.
