Do not use in external applications, on wet substrates subject to moisture rising or floating applications, in environments where water is always present.

Instructions for use

Preparation of substrates

The substrate must comply with current British standards and industry regulations. 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.

In particular, substrates must be treated with a suitable primer as shown in the table below:

Substrates

Preparation

Pour 4.5 – 5.0 l of clean water into a clean container; then pour in a bag of Kerakoll Levelflex Rapid, while shaking. Mix with a mechanical mixer until a smooth, lump-free and self-levelling mixture is achieved. Larger quantities of Levelflex Rapid may be prepared in suitable mixers. After the first mixing, it is advisable to leave the mixture to rest for approx. 2 minutes and then mix again briefly. Kerakoll Levelflex Rapid features a high degree of self-levelling capacity. 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.

Instructions for use

Application

Kerakoll Levelflex Rapid is generally applied with a flooring trowel. The use of a spike roller or aeration roller can be used to further improve the surface finish of Levelflex Rapid by removing entrapped air from the mixture.
In the case of low temperatures and high humidity it is advisable to keep the environment ventilated during application and during the hours immediately following application, in order to avoid the formation of condensation on the surface of the self-levelling product during the setting phase. Protect from air currents at actual floor level.

NB

• Product for professional use
• abide by any British standards and industry regulations
• do not use Levelflex Rapid to correct substrate irregularities greater than 15 mm in a single coat do not add other binders, additives or pigments to the mixture
• low temperatures and high relative humidity lengthen the drying time and can saturate the environment; this may have a negative effect on the quality of the surface of the self-levelling product
• an excessive quantity of water will reduce strength and the drying time
• respect any movement or expansion joints present in the substrate
• if necessary, ask for the safety data sheet for any other issues, contact the Kerakoll Worldwide Global Service
