Product Description

Kerakoll Keralevel Eco LR

Keralevel® Eco LR develops a perfect thixotropic balance which is ideal to correct walls that are out of plumb or irregular, and uneven floors without holding up site schedules and subsequent laying of floor/wall coverings. Rapid hardening.

Flooring and walls, for internal and external use, in domestic, commercial and industrial applications and on heat-radiant slabs.

Do not use:

On high flexible substrates subject to thermal expansion, plasterboard, gypsum; on wet surfaces or substrates subject to moisture rising or which are in continuous contact with water.

Instructions for use

Preparation of substrates:

In general, substrates must be free of dust, oil and grease, free from any moisture rising, with no loose, flaky or imperfectly anchored parts such as residues of cement, lime, paint coatings and adhesives, which must be completely removed. The substrate must be stable, non-deformable, without cracks and have already completed the curing period of hygrometric shrinkage.

Low-absorption substrates: smooth substrates with very low absorbency level or which are completely non-absorbent, such as ceramic tiles, marble floor tiles, epoxy and wall paints, residual traces of oxidised 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, the water-based, eco-friendly adhesion promoter, following the instructions for use and after having carried out thorough cleaning of the surface. Any substances used for surface treatment, such as wax or parting compounds, must be removed mechanically or using specific chemical products.
High-absorbency substrates: on screeds and plasters which are compact but very absorbent, first Primer A Eco, eco-friendly, waterbased surface isolation, in order to reduce and regulate the level of absorption. In the case of absorbent substrates with weak consistency, apply Keradur Eco eco-friendly, water-based deep consolidant. Respect the indicated waiting time before carrying out correction of the surface with a levelling product.

Preparation:

Prepare Keralevel® Eco LR in a clean container, first of all pouring in a quantity of water equal to approximately ¾ of the amount required. Gradually add Keralevel® Eco LR to the container, mixing the paste with a low-rev (≈ 400/min.) helicoidal agitator. Add more water until the desired consistency is obtained. The mixture must be of smooth consistency and without any lumps. For best results, and to mix larger quantities of levelling product, a stirring device with vertical blades and slow rotation is recommended. Specific polymers with high-dispersion properties ensure that Keralevel® Eco LR is immediately ready for use. The amount of water to be added, indicated on the packaging, is an approximate guide. It is possible to obtain mixtures with consistency of variable thixotropy according to the application to be made. Adding extra water does not improve the workability of the product, and may cause shrinkage in the plastic phase of drying and result in less effective final performance with a reduction in surface hardness, compressive strength and adhesion to the substrate.

Application:

Keralevel® Eco LR is generally applied with a smooth trowel. If necessary, the high level of thixotropy of the mixture allows for high levelling thicknesses with just one coating. It is advisable to press down hard with the trowel during application so as to regulate the absorption of water and obtain maximum adhesion to the substrate,. After that, the thickness can be adjusted as required. In the case of high thicknesses and extensive surface areas it is advisable to create levelling layers, using Keralevel® Eco LR, and then proceed to apply with a trowel and flatten for final correction. The appearance of the surface finish may vary depending on whether a smooth steel spreader or a sponge spreader has been used for application. For subsequent laying of ceramic tiles it is always advisable to obtain a roughened, porous surface. If an additional correction layer is required, it must be applied as soon as the previous layer is ready for foot traffic (≈ 2 hrs at 23 °C and 50% R.H.) but after the application of Keragrip Eco eco-friendly adhesion promoter, following the instructions for use. After this time, it is necessary to wait ≈ 5-7 days, depending on the thickness created, then apply Keragrip Eco and overlay.

Cleaning:

Residual traces of Keralevel® Eco LR can be removed from tools using water before the product hardens.
