Self-Levelling Compound, Ultimate Leveller (EWI-250)x40

The Ultimate Leveller is a self-levelling compound used for internal flooring and is suitable for floors in homes, offices, public buildings and places exposed to similar loads. This product is very easy to utilise and ideal for basic surface levelling including: cement, concrete, load-bearing anhydrite screed, and more.

The EWI-250 Ultimate leveller comes in a 25kg dry bag ready to be mixed with water. Once dry, the ultimate leveller provides the perfect substrate for ceramic tiles, synthetic flooring, parquet flooring, etc.


Before application, determine the level to which the compound will be poured. The level of the compound can be determined by using notable benchmarks or benchmarks made by using embedded dowels with screws in the ground the heads can determine the level. This process will ensure consistency throughout the project.

It is recommended to start work at the wall furthest from the entrance. If you are working in a large room, it is suggested to separate smaller working fields with a width of 3-6 metres, depending on the speed of the pouring mass. After pouring, it should be immediately spread with a steel trowel and de-aired with a spiked roller.

If the layer is greater than 20mm, it is recommended to level the levelling compound with a metal bar in vibration movements. Then, pour out the mixture with a machine, use a dual mixing unit. Work without interruption until the entire floor area in the room is covered.

Application Conditions
