Certified, extra‑rapid hardening, eco‑friendly, self‑levelling mineral product for the high‑performance, high‑thickness correction of irregular substrates, ideal for use in GreenBuilding.

This self levelling compound is for internal use and can be used for depths of 2-30mm. Keratech Eco R30 is suitable for use with all types of underfloor heating if bonded to a rigid substrate properly treated with a suitable primer. You can tile on the new surface in just 3 hours.

Keratech® Eco R30 develops a high degree of workability guaranteeing an ideal surface for the subsequent laying of ceramic tiles and natural stone using eco‑friendly mineral adhesives.

Areas of Use


Self-levelling correction of uneven substrates, with extra-rapid setting and drying and compensated shrinkage. Thicknesses from 3 to 30mm. For internal use. For domestic, commercial and industrial applications with underfloor heating systems and minimum 15 mm flooring grade plywood overlay substrates.

Compatible adhesives:

- gel adhesives, mineral adhesives, with SAS technology, single and two-component organic adhesives

- reactive-epoxy and polyurethane, single and two-component cement-based adhesives, dispersed in water or solvent solutions

Covering materials:

- porcelain tiles, ceramic tiles, klinker and cotto of all types and formats

- natural stone, recomposed materials, marble

- hardwood floors, textiles, rubber, PVC, linoleum

- protective resins for concrete

- raised floors

Suitable for use on mineral screeds or screeds made using Keracem® Eco Pronto 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; underfloor heating systems.

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.

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 flooring grade asphalt and bitumen, 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 selflevelling product. The side joints must be protected with a suitable deformable band to prevent leakage of material.

Instruction for use

Prepare Keratech® Eco R30 in a clean container, first of all pouring in a quantity of water equal to approximately ¾ of the amount required. Gradually add Keratech® Eco R30 to the water in the container, mixing the paste with a suitable low-rev (≈ 400/min.) electric mixer. Then add more water until a fluid, smooth, lump-free mortar is obtained. Keratech® Eco R30 is immediately ready for use. The amount of water indicated on the packaging is merely an indication.Adding extra water does not improve the workability of the self-levelling product, and may cause shrinkage during drying and result in less effective final performance with a reduction in surface hardness, compressive strength and adhesion to the substrate. Excess water causes the colour to change to beige. Keratech® Eco R30 is applied with a smooth trowel. Application with plaster pumps allows the user to very quickly achieve a smooth high-thickness finish for large areas. Using a cylindrical section, lightened levelling bar helps the self-levelling product to create a smooth surface even when applied in great thicknesses. Application of a further substrate correction layer must be carried out as soon as the previous layer is ready for foot traffic (≈ 3 hrs) by laying Keragrip Eco, a eco-friendly single-component, water-base adhesion promoter, following the instructions for use. In the case of low temperatures and high humidity levels it is recommended that the room be kept well aired after application.


Electrical mixer, spreader and trowel, lightened levelling bar. Wash tools with water before the product hardens.
