    Default MDF instead of plasterboard?


    Hello all.

    First post here for me. I work as a freelance 'art technician' mainly installing exhibitions but also building new exhibition spaces.

    As you will all probably know, the usual method for building stud walls in galleries is to first fix a layer of 19mm plywood then a layer of 'tapered edge' plasterboard. The plywood is used in order to give flexibility as to where art work can be hung, without having to locate a stud. Unfortunately, this method is too expensive for a lot of galleries, which simply can't afford to lay out for two types of sheet material.

    One option is to use MDF as the sheet material. Of course, it is almost impossible to build with MDF without the joints cracking, especially in the very dry often over heated environment of an art gallery. Even with a 'heavy' chamfer.

    So my question is: is it possible to taper the edge of the MDF and then proceed to tape and joint it in the same way as plasterboard and will this produce a more stable joint?

    I have a great deal of experience with machining so making a cutter to fit a spindle moulder or even electric planer shouldn't be too much of a problem. Perhaps a tool already exists?

    My main concern is that if I go to the trouble of investing time and money into this, will the joints hold up without cracking?

    Many thanks, I hope someone can help.

    Try Fermacell boards. They are very resilient and can be fixed straight in to.

    Thanks for your reply TonyM.

    Just two quick questions, what is the surface of this material like (can it be painted directly or does it need to be skimmed) and is it readily available?

    You could use Rigidur,it can be jointed and you can fix to it.

    art tech i do a lot of taping for a company that does exhibition work.on on gallery they used mdf with chamfered edges. unibond the joints,doulble scrim and taped as normal.
    every 3 months the areas get changed to what the artists require,so holds up pretty well.
    on a whole prefer board but you can get round it this way.
