    Advice needed: how to level an archway under stairs

    Hi community Does anyone know how you can level a ceiling render which has a slight slope so that a door can fit nicely. I've attached a photo for reference. Research suggests using hard foam board. Scrubbing the slope... Cutting and gluing it on. Not sure if anyone here has better advice

    Using tile backer foam board for internal walling of single skin block wall.

    I am curios if this is doable or would work. I have a small single skin block shed. Now I am wondering if you can use foam tile backer board like Q Board dot and dabbed to the wall as both the vapor barrier, insulation and paneling without using plasterboard? This panel is meant for wet rooms...
