Applying vinyl tiles to a not-brilliantly screeded conctrete floor..

self levelling compound.

A couple of mm of self levelling compound would seem like the ideal option.

If you want a cheap option, the Wicks latex one is not bad. If you want a top end solution Mr. Watts will be along to extol the virtue of the F & B products shortly ;-)

F Ball Stopgap 300 is what I used and it really does (mostly) slef level as long as you push it about first so it wets everything.

You need the green primer first which helps prevent water getting sucked out too.

If it's just that the surface is a bit rough, ordinary interior filler will do. The guy that laid our vinyl said he uses it all the time for

Yes, I wondered about filler. U thought about filler, but then I thought that cement would be more likely to stay put. Neat cement does spread beautifully smoothly, I seem to recall. (And I just happen to have a bag of it waiting to be used up.)

I'm sure the self-levelling stuff would work too (at a price). I don't have a Wickes near by, unfortunately, although B&Q has it at £10 per 2sq m.

Thanks to all. Al

Did that :) Eternal September might be a bit laggy.

If the surface is friable, another good trick is to coat it in:

dilute SBR - that will stabilise almost anything and penetrate well and will not be affected by any damp. And the vinyl adhesive will stick to it like s*it to a blanket.

You could also machine grind or polish concrete.

Ah but cement won't stay put in thin layers :) Fillers will. BTW the stuff they sell in a tube goes off in no time and spreads well.

Neat cement sets too brittle for this purpose, self levelling compound contains fine sand, latex and other additives to prevent this

Just mix it like piss and pour it on, give it a wipe over with a trowel and after it's dried, lay your tiles
