Leca® Uno Pre-Mixed Concrete (25L Bags)

Leca® Uno for filling and leveling interior and exterior floors, applied in a single layer - increasing thermal and acoustic improvement of floors. 

Suitable for application in new construction and rehabilitation works, in thicknesses from 4 cm.

Mix Leca® Uno with water (5 litres/bag) to obtain a homogeneous mixture with a shiny appearance. 

• If you use a continuous mixer, the amount of water must be adjusted to the type of machine. 
• Spread the material across the entire area to be filled. 
• Level to the desired thickness using a level and regularize with a manual or electric trowel.
• Keep the material moist for the first few hours and create retraction joints, if necessary. 
• After drying (24 hours), the material is ready to be covered with ceramic material, natural stone or floating flooring or screed.

• Compressive strength 28 days: ≥5 N/mm2 (5 MPa)
• Flexural strength 28 days: ≥2N/mm2 (2 MPa)
• Fire behaviour: non-combustible (Class A1)
