Keratech Eco R30 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. Low CO2 emissions and very low volatile organic compound emissions, recyclable as an inert material at the end of its life.

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

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.

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 orange. 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. After this interval, it is necessary to wait ≈ 5 – 7 days, depending on the thickness created, and then apply Keragrip Eco, after which the subsequent applications may be carried out. In the case of low temperatures and high humidity levels it is recommended that the room be kept well aired after application.
