How do you prepare hardwood floors for self leveling compound?

How thick can self-leveling compound be?

Suitable for use on most common subfloors such as sand/cement screeds or concrete. It has high flow properties making it ideal for smoothing. It can be laid up to 6mm in depth.

How do you use a self-leveling compound?

How do you level a hardwood floor?

How thin can you lay self leveling compound?

The minimum thickness advised for many levelling compounds is only 2 or 3 millimetres (some require a minimum of 5mm). And whilst even a millimetre less than the prescribed minimum might not seem that significant, it can cause problems.
