Hi there im new to the forum 
Iam rendering a back wall of a house for the first time next week and i have got a couple of questions if you wouldnt mind helping with?
The area iam rendering is approx 9 ft x 15 ft. how many bags and what materials (eg cement, sharp sand etc) should i be looking to buy for each coat?
And what is the mix eg. do i need lime in both coats ? do i need a waterproofer in both coats? someone mentioned feb mix? i have never heard of this. do i need it in both coats?
the wall iam doing has some old brickwork ( high suction) some old brickwork thats been painted (low suction) and some new brickwork (also low suction) all in it. what the best way to get an even level of suction on the whole wall?
In some parts of the wall where there are pipes etc going into it. there is a spongy material that looks like expanding foam that has been used to fill the gaps around the pipes. Will i be able to render over this?
Finally this is how iam planning on doing the job can you tell me if it seems ok
fix beads - apply scratch coat - rule off with feather edge - scratch. week later apply second coat - rule off with feather edge - rub up with float - pray it turns out ok
thanks for taking the time to help me its really appriciated
