EWI-250 Self-Levelling Compound Ultimate Floor Leveller Application:

 · Before application, determine the level to which the screed 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.

 · When pouring out the mixture with a machine, use a dual mixing unit.

 · The work should be performed without interruption until the entire floor area in the room is covered.


Substrate Preparation for EWI-250 Floor Leveller:

 · All surfaces should be clean, dry, and free from any materials which may impair the application.

 · Also, prime the substrate with EWI-310 universal primer and ensure that all the substrates are load-bearing and stable.

 · This should be checked before application.

 · Concrete substrates must be at least six months old, and cement screeds must be at least four weeks old before application.

No matter whether you choose a local installer or a national company, there’s a few tips to help you find the right installer for your home insulation improvements, such as asking for recommendations and making sure that they’re part of a certification scheme. This makes sure that they have the right skills and standards of workmanship to carry out the installation, and you can be sure that they know exactly what they are doing.


1. Thermal inspection picture in portfolio

It’s worth seeing a installer’s previous work. There’s no harm asking if you can see any properties nearby that they’ve installed insulation in. Best way would be to see Infrared Thermal Imaging Inspections. Thermal cameras spot small, but key changes in temperature in different areas of a house, identifying problematic areas that the human eye never could and some that a visual inspection could only hypothesize.

2. Reviews

Along with checking recommendations and previous work, finding reviews online can often be a great way to find out if they provide a good service or not. However, it’s best not to solely rely on reviews you may find or review websites, as there’s no controlling who writes them.

3. Compare prices

Comparing prices will also ensure companies can’t take advantage of you and give you a fair price. 

4. Word of Mouth

The best way to find a great insulation installer is through recommendations. Make sure you ask friends and family. They will most likely give you their honest opinion and can tell you from first hand experience.
