Advise on OSB exterior wall left in rain
Posted: Mon Feb 15, 2021 11:59 am
My builder has used OSB for the exterior wall of one of the bedrooms (we were expecting brick). The wall is to be rendered on but due to delays it has been left out in the open for over 10 months, being hit with a lot of English rain. I’d appreciate any advise on if the boards can be left out for such a long time, and if I should be asking for them to be replaced before the render is applied? Thanks a lot.
