Talking of screed...

[Mungo "two sheds" Toadfoot]

Is it suitable for outside use, on a path?

I'll explain better: running along the back of my house is a strip of concrete, about 25' long by 5' wide, which is evenly flat but quite badly cracked. Rather than digging the whole lot out and re-laying more concrete I wondered if there's something available which would give a nice "new" surface but be no more than about 15mm-20mm thick?

It can't be too thick because there's a rainwater drain in the corner and a big square metal access lid to the sewer right in the middle of it. What I'd like is something which could be poured on and left to level itself. Yeah right :)

Any ideas?

screed no good except in bulk. Tarmac or bitumen and chippings?

[Mungo "two sheds" Toadfoot]

There's a thought. That sounds very...sticky though.

Smash the existing up even more to give a good bite

then mix a fine concrete using small 3/8 chippings. That will do the job. IMO.

test a bit first if unsure.....

Yes. that's sound. Smash it and make new mix using old bits.

4" of generalised muck and concrete will make a fine new path.
