conny rendering advice plz?

[zombie]

hi chaps...

after a little advice if poss....wanting to slowley dip my feet with external work and ive been asked to sand & cement render a dwarf wall on a conny....

its currently your standard blockwork and has been built about a month or so....

ive got a few quesions id like to ask regarding suitable mix ratios and meshings etc... but will probably ask them later as individual questions so as to not make this thread to complicated...

my original questions realy are with it only just being built how long if at all would you be happy letting the footings/brickwork settle first?... and aslo does a sand & cement finish seem an ok approach for this sort of substrate etc.

Thanks chaps zombie

Conny? is exactly what. concrete or conversion?

There should be no need to leave it to settle for any longer, yes S&C would be suitable and if you do a search there is a guide to mix ratios for different substrates.

Conservatory I'd guess.

Use webber ocr no need for scratch coat lay it on rule it off float and sponge it up like you would with normal sand and cement .

essexandy....thanks appreciated

ivor...thanks ivor...is webber ocr along the same lines as wetherbys bagged render that has scrim adhesive labelled on it? that you use on ewi before the final coat (coloured textured topping) etc

Don't complicate things. Just go with plain old sand and cement 2 coat work.

Like Andy said do a search for mix's and additives.
