  • At some point I need to box in these corners round concrete pillars, have 8 to do in total and while most are not prominent in the rooms I want to do a reasonable job.
    Don’t want to use ply and not a fan of MDF as the edges/joins never look great. MDF was used before when the pipes ran all round the room and it looked terrible.
    I could do them in 9mm plasterboard as it’s easy to cut and I have plenty of experience shaping to fit with a sureform to a perfect fit but then I have to corner bead all the joints and skim or fill them. The edges remain crumbly and dusty so a lot of work with this method.
    I have some tile backer board that’s easy to cut and trim but it has a waffle texture.
    Is there some kind of smooth builders board that’s easy to cut with a knife, and corners can be filled then painted?

  • I've done loads of these (sadly). 9mm mdf and sand the edges to 400 grit is the way I've settled on. It does take some work to get a good decorative finish. I glue and screw them together, countersunk screws. Toupret wood filler to cover screws etc.
