Hello lads as the title says got a job to look at the sub floor is half floorboards and half asphalt with some well stuck ceramics on top. I was thinking 6/ 9mm ply on top of the floor boards nailed down with ring shanks at 6 inch centres . Prime full area with p51 or similar then ardex na all over . The finish will be camaro . Cheers ?
Shouldn’t really go deeper than 6mm over ashpalt. So 6mm ply over floorboards nailed every 4 inches. 3mm coat of NA no primer Ardex 1c DPM Another 3mm coat of NA Full feather over the lot
Asphalt is also the dpm and tends to be found in older properties direct to earth and is normally damaged or cracked so it’s best to use a liquid Dpm to be safe
OK cheers mate . What about on quarries ? Dpm then na ? Im rusty as you can prob tell . I need to go on a refresher course i think .
