Hi all,

I have a concrete slab which in places has some small shallow (say a couple of mm) indentations. I need to fill them to make it flat (doesn't need to be smooth just flat) and was wondering what you would suggest. Given the small thickness, I was thinking of exterior self levelling compound but then wondered whether maybe tile adhesive would be better?

Anyone any ideas?

Thanks

Lee.

I used a resin based cement for levelling a worn step and that has
lasted about 40 years so far.

Yes, I doubt if cement itself will adhere to the surface well enough and
will break up over time.

Self level,ling should be good. Tile cement is not a lot of cop under
high wear or damp conditions.

Colin's suggestion sounds the best so far.

Those who want slavery should have the grace to name it by its proper
name. They must face the full meaning of that which they are advocating
or condoning; the full, exact, specific meaning of collectivism, of its
logical implications, of the principles upon which it is based, and of
the ultimate consequences to which these principles will lead. They must
face it, then decide whether this is what they want or not.

The big advantage of resin bonded cement is that it can be taken to a
feather edge without any problems.

I have used this stuff before on concrete repairs, very tough, can be
smoothed out quite thin and is weather resistant. I did one repair outside
last year and despite snow, ice and anything else the weather has thrown at
it it is still intact.
