Hi everyone,
Was wondering if anyone has experience with stucco on Hebel (Aerated Concrete Block).
I have been told to use acrylic render rather than a cement based render but when googleing the topic there seem to be a lot of people recommending stucco.
Does anyone have any experience with either of these?
STUCCO MIX
For a scratch coat, you will need this mixture:
window.google_render_ad(); 1 part portland cement
1 part hydrated lime
2 1/2 to 4 parts sand
For a brown coat, you will need:
1 part portland cement
1 part hydrated lime
3 1/2 to 5 parts sand
Finish coat ingredients:
1 part portland cement
1 part hydrated lime
1 1/2 to 3 parts sand

Did a Hebel fence couple of years back but I used 1p cream cement, 1p hy lime and 3 parts sand for all 3 coats, to give it a limestone finish.
Long ago I also did a retaining wall using clay bricks, a quick cement render followed by acrylic render. I didn't moisture proof the back of the wall properly and soon after the water pressure behind the wall caused the acrylic render to start bubbling and peel off. I scraped it all up and redone it with thin coat of cement render (1p cement , 1.5p sand) and 20 years on its still intact.
cheers
