I have a small amount of recovered parquet flooring which was originally laid in a bitumen on a concrete floor. I want to relay this on a timber floor (WBP layer on top of boards). I was wondering if anyone could recommend or identify a suitable new adhesive / bed that will bond adequately with the residual bitumen on the tiles. I am advised that the modern adhesives don't bond well and that the older cold bitumen emulsions have been taken off the market. this is a DIY'er job and while I could scrape off all the old bitumen, there is always a residual layer (aside from the fact that it will take weeks to scrape off all the old stuff. I was thinking of just sofening it with a hot gun and laying it directly to the WBP.
Any help would be great.

I have only done this for my sister and i used gripfill (adheres and lets you fil any gaps)adheshive. It was a small porch and is still there.


But i stress it was a non paying diy job for family

Hi, Came accross your post by accident whilst researching porcelain tile sealers. I've just laid 75 sq m of Mahogany flooring (DIY) and did a fair amount of research before I started. I'd recommend leveling the floor area using 9mm ply screwed to the old floor and use gripfill or similar to keep the ply level. Everyone I spoke to recommended leycol 5500 flexible advisive (it made by laybond who also make Gripfill). You do unfortuantly have to remove as much of the old* Bitumen as you can as if you don't the adhesive sticks to the old bitumen and softens it which means your blocks might not stay secure. I used a Chisel and tungsten carbide harris decorators scrapers from Screwfix and clamped the blocks in a workmate. if you have just a small area it won't take too long (i'm told putting the blocks in bags and into the freezer makes the bitumen brittle and easier to chip off but with mine it was brittle and came off reletively easily anyway (just took a long time as I had so many to clean). Check out diynot forum you'll find posts from a company called Wood U Like and if you visit their site you'll find usefull info about refitting reclaimed parquet.*

did you clean all the sides of the blocks before laying them?

The OP was just a guest, so start a fresh thread to be advised by others.

I wouldn't put money on it. I knocked off a dozen tiles in my bathroom when replacing a door frame. I still gaze at them sitting on the window-sill 7 year later gathering dust and I find myself saying "Next Weekend....."
