    want to float solid oak on combo of parquet and concrete

    hah - i know what you mean. the guy who came spotted a small dip in the hall i hadnt noticed, and was smelling all the time (a manky dustsheet that got wet yesterday threw him a bit). damp readings were all less than 16 (mostly 11 ish) no idea of units, on his damp meter and he seemed happy...

    want to float solid oak on combo of parquet and concrete

    thanks- my pref is clearly to go for the easy option. may need to do some persuading on going for this option. what concerns me is the cost is going to be huge for the full dig up, screed and stickdown. cost of 50m2 of screed 7mm deep alone is going to be high. what type of underlay shd i...

    want to float solid oak on combo of parquet and concrete

    Flooring guy reckons anything onto the parquet/bitumen will cause it to buckle. Indeed I've discovered 2 folks in the street had this issue floating laminate over the self same parquet. So looks like I will be shoveling up 50 sq m of parquet, and have to get "most" of the bitumen off myself...

    want to float solid oak on combo of parquet and concrete

    sounds good. i'm guessing the concrete does have dpm in it, since it only has carpet and underlay sitting on top of it right now. i've got another fitter comeing round to opine and test. nice to have a view before hand tho. out of interest one guy said to level the parquet floor up to the...

    want to float solid oak on combo of parquet and concrete

    hi have read all the similar posts but still unsure about this. i have about 50m2 of parquet living dining and 10 of concrete extension. I really really do not want to have to lift the parquet and bitumen. I cant really lay wood over whole area as it will take level up to high (ply + foam...
