self-levelling compound

Our Self-levelling compounds are easy to use and create a strong adhesion to a range of substrates. The finished result is a durable, level and smooth surface that is great for use with different types of flooring.

We have a few different types of self-levelling compounds, all of which are suitable for application at a range of thicknesses. In today’s blog post, we’re going to be outlining the difference between our three self-levellers and then explaining exactly how they should be used.

EWI-250 Ultimate Leveller

The Ultimate Leveller is our standard levelling solution for internal floors. This product is great for levelling floors that require a bit of finesse, as it can be applied up to 20mm thick.

  • Suitable for application using a spray machine
  • 2-20mm
  • Easy to use, self-levelling compound
  • Suitable for under parquet, tiles, carpet and for use with underfloor heating

EWI-251 Deep Fill Self-Levelling Compound

As the name suggests, the Deep Fill Self-Levelling Compound is intended for application on floor surfaces that require a bit more product to achieve a level surface.

  • Suitable for application using a spray machine
  • 5-35mm – greater application thickness
  • Easy to use, self-levelling compound
  • Suitable for under parquet, tiles, carpet and for use with underfloor heating

EWI-254 Quick Set Self-Levelling Compound

If you’re levelling in a hurry, then we highly recommend our Quick Set Self-Levelling Compound. This product is safe for treading after 3 hours and will have fully cured after just 3 days.

  • 2-30mm
  • Easy to use, self-levelling compound

How to Install Self-Levelling Compounds

Our self-levelling compounds are very easy to use, but a lot of preparation needs to go into making sure the substrate is adequately prepared. Cement surfaces that are extremely rough need to be filed down, and any dust, dirt or grease must be removed from the substrate. Cracks within the floor also need to be repaired. If there is no threshold within the doorways, then temporary battens should be installed in these areas to prevent the self-levelling compound from running off into the other room.

You then need to establish exactly how thick you need to pour the product out to. To do this, place your spirit level flat to the floor and lift the lower end until it reads straight. You can then measure the gap between the bottom of the spirit level and the floor, which will enable you to determine the average thickness that you should pour the product out to.

Before application, you will need to mix the product with water (either inside of the spray machine unit or just using a bucket and mixer). Once this has been carried out, the product is simply poured out onto the floor before being spread with a trowel to distribute the product.

We recommend that if you are levelling a particularly large surface area, you should divide the room up with wood battens. This way you can pour the product out to fill the selected area, and then keep moving the batten backwards to create more space to fill.

Once the area is covered in the product it needs to be raked using a spiked roller. This will remove trapped air from the material and therefore prevent air bubbles from affecting the way that the product sets.

For the EWI-250 and EWI-251 you will need to wait 5 days for the product to cure before you can carry out any further works and lay down your chosen flooring. The EWI-254 has a faster curing time of just 3 days, so if you’re in more of a hurry then this is the best product for you.
