Area of use
Self-levelling correction of uneven floors, with extra-rapid setting and drying and compensated shrinkage. Thicknesses from 3 to 30 mm. Interior floors. For use in domestic, commercial and industrial applications and on heat-radiant slabs. Compatible with all cement-based, reactive-epoxy and polyurethane two-component adhesives, dispersed in water solutions.
– Porcelain and ceramic tiles, klinker, cotto and natural stone of all types and formats,
– Recomposed materials, hardwood floors,
– Textiles, rubber, PVC, linoleum, protective resins for concrete.
Suitable for use on mineral screeds or screeds made using Rekord Eco or Keracem® Eco as binder
or ready-for-use premixed products, cement-based screeds, concrete and those with well anchored
residual traces of cement-based additives; under-floor heating.
Do not use:
Do not use in external applications, on highly flexible substrates subject to thermal expansion, or on wet surfaces or substrates subject to continuous moisture rising.
Instructions for use
Preparation of substrates:
Substrates must be free from dust, oil and grease, free from any rising damp, with no loose, flaky material. The substrate must be stable, non deformable, without cracks and have already completed the curing period of hygrometric shrinkage. Smooth substrates with very low absorption or which are completely non-absorbent, such as ceramic tiles, marble floor tiles, epoxy paints, vinyl glue residues of adhesives and smoothed concrete coatings which are compact and properly anchored, must be prepared by means of mechanical abrasion or by application of Keragrip Eco, a professional, single-component, water-base adhesion promoter, following the instructions for use. Any substances used for surface treatment, such as wax or parting compounds, must be removed mechanically or using specific chemical products. On screeds which are compact but very absorbent apply Primer A Eco water base, eco-friendly surface isolation product, in order to reduce and regulate the level of absorption and to avoid the formation of air bubbles in the self-levelling product. Respect the indicated waiting time before carrying out correction of the surface with a self-levelling product. The side joints must be protected with a suitable deformable band to prevent leakage of material.
