Hi, I’d really appreciate some help/ advice I have a large rear extension, extending an existing room, but the new bit is flat concrete, & the old bit is old floorboards. Thought we could get away with it, but we can’t it’s just too uneven & lumpy particularly in the old floorboarded section The 2 sections are relatively level with each other, but it’s just too lumpy/ bumpy How could I now level both sections? Baring in mind half is concrete, & half old floorboards. Wanting to prep for a nice flat new laminate Appreciate any help guys
6mm plyboard to the timber area and flood the lot including the concrete part with a fibre based screed like Mapei Renovation.
