Hard black substance under carpets

Anonymous user 23/02/2024 - 3.30 PM

We have removed carpets to decorate and found a hard black floor underneath. When removing gripper rods which we nailed into this, chunks of the black floor have broken away. It looks quite brittle and almost like seaside rock but very black! The house was built in 1980 and the room is on the ground floor. As some small pieces are now broken away id like to get it repaired. Any idea what it is and what would be needed to repair these patches ? Thanks

The substance you are seeing is asphelt used in also of properties . The gripper should have been glued to this and not nailed , where it has broken it can be repaired with quick drying cement available in BQ . WICKS .When gripper is refitted it must be glued down

Its a asphalt floor, and gripper should never of been nailed into it, ideally glued really, only way around it now in my eyes and what id suggest is for floor to be primed then screeded over or if you wanted a cheap fix just do the perimetre then glue the gripper rods in place.

It may have had vinyl tiles laid which were laid on bitumen adhesive & the pinning of gripper around the edges of rooms with concrete floors quite often causing the edges to break away. You may have to fill around the edge & stick the gripper.

we used to find this stuff in the older 50s houses.we used to call it chocalolly.Some times it would break when being nailed yes.To repair it I think floor leveller would be OK or something like Tetreon both dry hard .If you need to put gripper down again it might be better to stick it instead of nailing .Hope this helps.
