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.
Not what I wanted to hear!?
When I have time I’ll see if I can find a foam cored tile board that’s smooth as it’s so much easier to work with.
This is one of those jobs to be done after we move in so I guess I have a couple of years to do them..
