LECA® QUOTAZERO

QUOTAZERO is the finishing screed for indoor and outdoor laying with a low thickness from 3 to 60 mm suitable for the direct laying of glued floors (even those sensitive to humidity) and waterproofing layers (both prefabricated and liquid membranes).‎ QUOTAZERO is a pre-mixed bagged product made up of selected aggregates, specific binders and additives, it has a density in place of about 2.‎100 kg/m3, with controlled shrinkage < 450 µm/m for surfaces up to 50m2 without joints and reinforcement netting, for the benefit of improved quality and safety of the flooring.‎ It is suitable for laying any flooring, both moisture-sensitive (such as parquet, rubber, PVC, linoleum, resilient flooring, etc.‎.‎), as well as those that are not sensitive to humidity (such as ceramic tiles, even large format ones, and similar), starting from 1 day in the minimum thickness of 1 cm (for other thicknesses and drying times see the technical data sheet).‎ QUOTAZERO is resistant to compression (25 N/mm²) and flexural strength (6 N/mm²).‎ Installation is easy and safe with the use of traditional site equipment such as concrete mixers, planetary mixers, auger mixers, also continuous, pneumatic pumps for sub-bases.‎ The screed has an earth-wet consistency and a certified thermal conductivity of λ 1.‎48 W/mK, which makes it suitable also for applications with underfloor heating systems.‎ Advantages: LOWTHICKNESS QUOTAZERO is suitable for the formation of low-thickness screeds, 3-60 mm, even on radiant piping and without reinforcement nets, for all applications and types of coverings.‎ PRACTICAL AND SAFE The bagged packaging makes it possible to obtain a product with constant performance in all conditions, and shorter processing times than traditional sand/cement with normal application methods.‎ In addition, the flooring can be glued directly onto the surface once the substrate is dry.‎ RESISTANT The remarkable mechanical properties (25 N/mm² at compression) allow the laying of any type of surface finish.‎ DRY Applied at a thickness of 3 cm, after 24 h.‎ it reaches residual moisture values suitable for laying ceramic-type flooring that is not sensitive to moisture, and after 6 days it reaches residual moisture values of <2%, ideal for laying moisture-sensitive flooring such as parquet.‎ INCOMBUSTIBLE Totally mineral-based, therefore with "Euroclass A1fl" fire reaction.‎ Fields of use: - Screed for modifying slopes or levelling in thin layers on existing floors.‎ - Screed for levelling/restoring the flatness of existing concrete/ screed surfaces.‎ - Screed for modifying slopes of flat roofs, terraces and balconies prior to waterproofing treatment or laying of tiles.‎ - Screed for levelling out thin layers to regularise the bottom of swimming pools/pools to make them suitable for waterproofing.‎ - Screed for restoring steps, levelling or correcting the level and slope lines of cement screeds or ceramic floor tiles.‎ - Screeds in general for indoor and outdoor use, also with low thickness from 3 mm to 60 mm.‎ - Screeds for laying moisture-sensitive (parquet, PVC, linoleum, rubber, etc.‎) and non-humidity-sensitive (ceramic, etc.‎) floors.‎ - Screeds on underfloor heating and cooling systems.‎ - Screeds for radiant systems
