Screed / Marley tiles and bitumen residue ?

Hi, 1st post so go easy on me. I am hoping to have some solid oak flooring in my hallway at home, which would be stuck down. The sub floor is currently half sand/cement screed and half Marley tiles. I am looking for advice on the best way to get the floor ready for the boards. Do I put some leveller over the whole thing, take Marleys up then level or take up and do "something" with the bitumen residue ? Also any products that you could recommend as well. Thanks for any replies. Steve

 

Marley tiles would need to come up but be advised they do contain white asbestos.

 

Take up tiles (probably asbestos type) grind bitumen away then screed with water based high strength screed, probably best getting a floorer in to be honest.

 

Use a 20mm engineered Oak with a 6mm wear layer and float it on acoustic underlay, more stable,easier to lay, will look the same, and will last as long as the solid, less aggravation with the subfloor.
a lot of clients only want solid because they think its better, they became like solid only snobs
the wear layer on solid is about 8mm before you hit the tongue so not a lot in it,
the engineered also tend to be longer planks from my experience, a lot of cheaper solids on the market send you out tons of 300mm lengths
just have a look into it Tommo and compare

 

Second uv's suggestion. Also you won't get seasonal movement showing in the floor

 

ENGINEERED ALL THE WAY TOMMO, I'VE RECENTLY STARTED TO AVOID & ULTIMATELY UNDERTAKE SOLID INSTALLATIONS DUE TO THE STRUCTURAL STABILITY, OVERALL PERFORMANCE & SUPERIORITY OF ENGINEERED vs SOLID...

BRAVO UVc, EVERYTIME...
