The timber looks like it has had maybe an undercoat and thats it. The sheet cracking looks more like structural movement. Stewie Re: Help please: Porter Davis 5 year old FC (Fibre Cement) S 3Oct 28, 2014 7:10 am I can't comment on the FC sheeting but I thought exterior enamel paint on wood had a life of approximately ten years? If they had been varnished I would have understood it but paint? Re: Help please: Porter Davis 5 year old FC (Fibre Cement) S 4Oct 28, 2014 8:49 am Hi Overwhelmed2 At a guess they appear to be tension cracks caused by sagging (unfortunately timber sags and deflect while FC fixed vertically cracks)? Do you have photos of the inside of the wall framing/roof. Do you have the original engineering drawings for the house Is there excessive deflection of the support beam supporting the wall Sorry more information is required...

Attaching more photos of the construction stage. I assume this is what you mean by photos of the wall framing/roof? Are engineering drawings the contraction drawings? not sure if these are the right ones. R2 R3 R4 is the line where there are cracks happening. Next pic is the ground level and it correlates to 1B1 and 1L4 line. LOL I hope I'm making sense Thanks for the help and I hope these photos help.
