Self levelling compound - mix of screed and tiles.

[ajpepe72]

I’m looking for advise on the best product to use to self level our existing kitchen and new extension in prep for lvt.

Kitchen is ceramic tiled and knocked through into extension which is screed.

I’d like to leave the existing tiles there and go straight over the top if possible due to mess and also the fact that underneath the tiles I’m pretty sure is the old 70 asbestos tiles.
Any recommendations on primers and compounds ?

Thanks

What’s the levels like?

Is it glue down or click LVT.

You will need to do a moisture test on the screed and the ceramics area won’t have a effective damp proof course for glue down LVT

Levels are fine, maybe 7mm difference between lowest and highest spot but they just spots, it’s pretty uniform all over.
Lvt is glue down and screed has been down for nearly a year now so no issues there with moisture.
I was wondering if something like Mapei eco grip plus would be worth applying to the existing tiles.

That will sort out the screeding compound sticking to the tiles.

Which of the actual Mapei levelling compounds is best or which brand would you use ?

Mapei Renovation over that will be fine.
