Andy H Posted January 30, 2021 Posted January 30, 2021 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
nod Posted January 30, 2021 Posted January 30, 2021 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

Is that correct ..? 2
Vijay Posted January 30, 2021 Posted January 30, 2021 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 2 1
