All types of self-levelling compound can be built up in layers. I would even recommend it, if you need build up your floor quite significantly (anything above 10-12mm). If you are using a cement based self-levelling compound that you add water to, you should wait for your first coat to cure properly. Then prep the…
Strictly speaking, self-levelling compound is not a finished floor covering. Despite it being pretty good stuff, it is designed to have a floor covering applied over it. Its purpose is mainly to provide a smooth and level surface. It is not designed to act as a wear layer, Unless you buy a specific product like…
Yes, If you are using a cement-based self-levelling compound it is always best to use a sealer on concrete. Even if it’s just because the floor is dusty, sometimes it can be quicker to apply a sealer rather than hoovering it all up, but it’s best practice to do both. Sealing the floor can be…
Yes, Get it used up! The quality of the product inside will not be compromised. The only thing that causes self-levelling compound to go bad is moisture getting into the bag. There is a simple check you can do, Open the bag if it is still fine and powdery you are good to go. If there…

The chipboard floor covering will start to absorb the moisture from the self-levelling compound mix, causing it to swell and blow. Very Important: Cement-based self-level also has no flexibility once it sets, so if it is on…
If you lay your Self-levelling compound and leave it overnight it will be dry by the morning. Most manufacturers state that their products can be walked on in around 4 hours. I have found this to be true, but there is no right answer here, as it all depends on the Temperature, Relative humidity and…
No, You can’t directly apply traditional cement-based self-levelling compounds that you mix with water, on top of Bitumen. Further preparation of the subfloor is required. See solutions 1 and 2 below if you are using the cement-based self-levelling compound. You can, however, apply a 2-part Latex-based self-levelling compound, which does not require any extra preparation,…
A self-levelling compound will have a tendency to crack as it is only applied in a very thin layer. This is usually between 3mm-10mm just thick enough to smooth imperfections in the floor. Once the floor is level a floor covering can be easily applied, this could be LVT, tile, laminate etc. What causes self-levelling…
