Hi all
Just ripped up the carpet to find the (anticipated) 5 finger parquet (1960s). Pretty sure its a hardwood - not sure which - mahogany / teak maybe.
The carpet underlay was stapled into the floor across the room so any blocks with staples in came up with the underlay. The middle of the floor seems generally stuck down okay (as far as i can tell from knocking.
The carpet gripper bars are nailed into the parquet around the perimeter and so the bars pull up these blocks too - with others around them becoming loose.
One side of the room is fully glazed to the garden and here in particular lots of the blocks are loose to the point the you can just lift them away. The bitumen is fairly thin on the blocks and left behind is a layer of paper. This is stuck (or in some areas - not stuck) to the screed with more bitumen, but it is not super thick.
So the question is....what to do. Patch repair / glue back all loose areas (sika rapid dpm followed by sika 5500s adhesive ?) and then sand/seal ? Or tear up the whole lot ?
Im guessing that the edges of the slab/screed - particularly against the big window edge are getting more temperature change - hence why the adhesion has become particularly bad in these areas. My concern is that if i spend hours patch fixing and then get a sander on it more blocks will start to vibrate loose across the whole floor.
Hope someone can advise...
