Floor Leveller

Cemix Floor Leveller is a user friendly cement based product for levelling uneven concrete floors prior to tiling, carper, vinyl, parquet etc. Just add water and mix thoroughly to a pourable consistency. Pour it on the floor and it will self level with a very smooth finish. Under normal conditions access onto the floor is available after 1 -3 hours and the final flooring can be laid after 7 days. The obtained surface is so smooth that vinyl or carpet can be laid directly onto it and at the same time, provides a durable surface for use. Cemix Floor Leveller combines rapid hardening and self-flowing properties with low shrinkage. It is supplied as a pre-blended, dry powder designed for application at thickness between 3 - 30mm in one operation. Normal application thickness is 6 - 8mm.

Uses
It is designed as an underlayment screed for use on concrete floor to receive tiling, carpeting and to cover under floor heating coils.

5kg, 10kg and 20kg.

Water Resistance
After curing, Floor Leveller can be exposed to water spillage without damage. However, saturation with water over longer periods may reduce the strength to less than its normal value with full strength returning within 24 hours of drying out.

Coverage
Depending on the surface to be treated. Normal approximately 10kg of dry powder per square metre, corresponding to a layer of 6 mm thickness, is required. Dry powder consumption is 1.7 kg per mm thickness per square metre.

Installation
Preparation of substrate The surface to be treated must be hard, sound and free from surface contamination. All dust and debris should be vacuumed from the surface. Concrete laitance and old coatings should be removed mechanically e.g. by enclosed shot blasting, scabbling or scarification. Concrete contaminated by oil or grease may require flame gunning and/or treatment with a proprietary degreaser.

Priming
Cemix Multibond should be applied to the prepared surface at 1 litre per 8m2 on smooth concrete or 1.5 litres per 8m2 on porous substrates using a soft brush and allowed to become touch dry (1 -2 hours under normal conditions) before the Floor Leveller application.

Substrate
Floor Leveller is principally designed for application on concrete substrates. Uneven substrates can be leveled with it. Weak or soft substrates, such as asphalt, which may be subject to movement under imposed load (either in use of during material curing), must be removed. Contraction joints, construction joints and cracks in the substrate which may be subject to movement after installation of Floor Leveller must be maintained as joints in the new surface.

Surface Finish
In appearance, Floor Leveller can be compared to ordinary concrete flooring. As an underlayment, Floor Leveller is compatible with most commonly used adhesives and soft floor finishes as well as with hardwood flooring, ceramic tiles and athletic flooring.

Mixing
Use of mechanical mixer is recommended. Mixing time is between 3 - 4 minutes depending on the type of mixing equipment used. Floor Leveller should be used within 20 minutes. Only clean potable water should be used at 1L per 5kg powder.

Application
The mixed material is poured onto the surface at a constant pace when a screed of uniform thickness is required. Levels may be corrected by applying greater or lesser amounts of material as required, and falls may be maintained by pouring from the higher to the lower end. The freshly applied material may be lightly troweled with a serrated steel spatula to assist dissipation of surface bubbles and lines left by the hose. The semi-hardened material may easily be formed or cut allowing any necessary adjustments to be made.
