I want to lay some self adhesive vinyl floor tiles over some existing floor
tiles.

The existing tiles are the very brittle vinyl asbestos ones and have cracked
where carpet gripper has been removed. Bits of tile are missing & I reckon
it will look pants if I tile over the gaps.

Only two options I can see are to remove all the tiles including old
adhesive - which will be a pig of a job, or to fill the gaps with something.

Its going to be in a very thin section of filler & will need to bond to the
adhesive. It will also need to be fairly quick drying, but remain workable
for long enough to get it flush without sanding.

Any suggestions?

I'm thinking of the old standby on the group - car body filler.



Absolutely. It takes a while to cure in thin layers because not as much
heat is generated. Also worth noting that even a tiny amount of catalyst
will cure it eventually providing it's thoroughly mixed. Not helpful
when some manufacturers make it the same colour as the resin though

The best type of car filler for this purpose would be a Polyester base,
a bit like;

Polyester fillers use talc which are easier to rub and remain more
flexible than the cheapo rock hard chalk type fillers.

The catalyst is a different colour which makes mixing easier too.

They're all polyester, and talc is as hard as any other mineral to rub
down. Bondaglass do a cheapo "lite" filler, based on microspheres,
which is much easier. AFAIK the flexibility is down to the resin rather
than the aggregate. It's a different type to the ones used in GRP work.
