QUICK-DRYING LIGHTWEIGHT FIBRE-REINFORCED INSULATING SCREED. SUITABLE TO TAKE ALL TYPES OF ADHESIVE AND FLOATING FLOORING
Latermix Fast is a bagged pre-mixed lightweight insulating screed mortar of semi-dry “damp soil” consistency based on special Laterlite Plus hydrophobic expanded clay.
It’s ready for use after mixing with only water.
Its special formulation makes possible rapid drying times that enable ceramics or stone to be fixed with adhesive after only 36 hours and moisture-sensitive types of flooring (parquet, carpet, vinyl,
etc.) to be laid after 7 days (on a thickness of 50 mm).
Can be used in thicknesses of 2,5 cm or above if bonded to a supporting layer, and does not require mesh reinforcement.
It weighs 30% less than a traditional or flowing screed (approx. 1.250 Kg/m3 when laid), reducing dead loading. It is particularly suitable for reconstructing existing floors and roofs, or to prevent
excessive loading in seismic zones.
Strong, stable, durable, and CE-marked
It has high compressive strength (18 MPa), is CE-marked to denote conformity to EN 13813 (screed materials and floor screeds), is dimensionally stable and non-deformable, and retains its properties unaltered over time.
For interior and exterior use
It can be used in screeds and to create falls internally or externally.
Because it is 6 times more insulating than traditional or flowing screeds (? =0.27 W/mK) it improves the thermal resistance of floor and roof slabs and reduces thermal bridging. Its porosity improves acoustic insulation, including in association with specific resilient layers.
Non-combustible and fire-resistant
This is a 100% mineral non-combustible product (Euroclass fire rating – A1) that is fire-resistant and safe.
Suitable for sustainable construction
Its use of natural raw materials, its manufacturing process, which respects the environment, and the absence of harmful emissions (even in the presence of fire), make it suitable for sustainable construction as certified by ANAB-ICEA, the Italian Accreditation Institute.
