Looking for some advice on floor levelling if possible, please excuse my ignorance.
We have had an extension built and knocked down a few internal walls to make an large open plan area. The builder laid a concrete screed in the new extension and told us we need to put a latex self levelling compound over it before we lay the floor etc.
We now have uneven floors where the old house doesn't match the new house exactly, its about 15mm out in some areas, we plan on relaying the parquet blocks in the whole house so want to get it level.
The old house had parquet floor laid on top of concrete, my question is, do we need to install a new concrete screed in the old house and then lay a latex self leveller on top of that or can we just use a latex self leveller over the whole floor including the extension.
Hope this makes sense?
