Hmmmmm, if you don't even know the correct mix, how do you intend to put it on the wall without devaluing your house by thousands of pounds?

Rendering is a time learnt skill, you can't learn it on a forum.

There are two coats to a render btw, one has to be moisture resistant.  There are stainless beads to consider as a bell drip and over window heads.

There is just so much to know, only spending time with an experienced guy will point you in the right direction.  I have been a builder for 30 years and NO WAY would I render ANYTHING.  I get a guy in.  He can render the outside of a large extension in a couple of days so why do it yourself?

Not trying to be a smart-ass here, but it's much more difficult than it looks.

I'm sure someone will be along in a while to tell you exactly how to do it but 'on your head be it'....... (and it probably will be)  

If its only a small area why risk making a bad job of it????????????????

Jerry is right it is an extremely difficult job that is made to look very easy by the guys who know what their doing.

if you make a hash of it the cost repairing will far exceed the cost of getting it done in the first place


but hey someone might pop along with the mix and some instructions so best of luck if you go for it

Robbo.Wouldn`t you use waterproofer in the undercoat?Then 4 to 1 and lime for the top coat.
