Economical ICF external render

[Andy H]

I am constructing a single storey ICF building with 3 sides being close to neighbouring boundaries and not visible. What would be the options for rendering these 3 elevations economically?

 

Thanks - Andy

Sand and cement render would seal the blocks and be easy on the pocket 

Add a bit of lime to the second coat to bring it up nice and white

@nodI had always been told 3:1 sand cement base then 4:1:1/2 sand cement lime for the top coat. Is that correct ..?

would it need any mesh or mechanical fixing or would the render bond to the ICF?

Perfect 

Straight onto the ICF with the first coat No mesh needed 48 hours then top coat with a spade of lime in the mix Gives a white wash look

Surely not if the ICF is polystyrene?

easy to add fibre mesh at 50 mtr if needed 

Just press into the firs coat
