The outside of my house is rendered and painted. There were a couple of panels of render which were addled and I have now removed these to patch render them. Can anyone tell me:-
1) Does the surface of the brickwork need preparing in any way, before applying the render ie waterproofing, uni-bonding or something else
2) What mix should I use for the render and in how many coats should it be applied
3) Is the 1st coat a different (stronger or weaker) mix than the second
4) What type of sand is recommended for external rendering
5) Do I need to add a waterproofer into the mix and
6) What are the tricks for getting a nice smooth finish and how do you avoid shrinkage cracking between the new and the existing render when it dries
When I've finished the rendering, I intend to repaint all the elevations. I have posted my questions concerning this in the Decorating Forum.
Thanks in advance for any responses
