try this, find yourself a really quick spider, chuck it on a dry spot and chase it round the wall with the float, they'll stay away from the damp spots to keep their feet dry so they dont get render on em etc and that way you wont end up floating a bit that isnt quite ready...
not a lot of people know that.. ;)

ahhhhhhhhhhhh the old spider trick not heard that for years chris dont be givin out all the secrets.
 
if you think about it, your top coat has gotta be weaker so it's more flexible, to avoid cracking.

If you put a stronger top coat on a weaker scratch coat, it's gonna go t1ts up. Simples

How does this theory work on wet dash roughcast when the universal measure of 3(chips) 2(sand) 1(cement) is applied? when mixed together i would say that is stronger or as strong as a 4.1. ??
 
yeah see what you mean.

First thing that springs to mind is the weight and size of the aggregate in the mix. Perhaps this makes a difference?

Is concrete with larger aggregates comparable? It's a lot stronger for sure. Guess mixes change with aggregates..
 
if you were rendering an old cottage, you would use lime

say 5 -1 (5 sand and 1 lime) no cement at all

wrong again mate 2 lime 5 aggregate
 
I've been doing 3.5 to 1 followed by 4 to 1 for years and never had
any problems, mind you I always scud thermalites

It must be an Irish term. Stipple/slurry coat thrown onto the wall with a trowel.

bit like nisus's skimming ;D
