Can i fix plasterboard to mdf using no more nails?

Niv

Hi,

Tryimg to box in under the stairs. Stairs are 1cm thick mdf (well al, i can see from underthe stairs is and i dont think there is another layer on top of it under yhe carpet)., so fixing battons to the mdf is very hard because it is so thinand dont want to go through the stairs.

Can i glue some of the plasterboard straight onto the mdf stair? It is only to be used as boxing, no real weight to go on it, altjough maybe obe bit may be a shelf for up to 8 bottles of wine.

Any thoughts welcome.

The answer is yes you can stick Gyproc to MDF but don't use any of the waterbased adhesives.

"Gripfill" is a good one, green tubes (solvent based) but don't use the solvent free yellow ones because the MDF will suck the moisture out of the adhesive and won't stick.You must use a solvent based adhesive. "No more nails" will be ok as long as its solvent based.
Gyproc won't take weight but if you are intending to fix a horizontal shelf to the underside of the stair treads then screw MDF to the underneath of the stair tread, they will be at least 22mm -32mm thick .

Cheap way of making staircases, the more MDF used in them the cheaper they are. 8x4 sheet of MRMDF 25mm is less than £30-00 and you could get all the treads out of one sheet, much cheaper than using real timber ...... Still a c r @ p staircase though....:D

The stairs are the ones that where here when we moved in a few years ago. There is no signs of damage etc so would seem silly to replace them simply due to part of the structure was made of mdf.

Regarding the shelf bit, it did feel like a bodge to me, i was just trying to make some use of a space that would otherwise be boxed in. Chances are it woukd ultimately be used for gloves and scarfs, the wine thing was a worst caee .

I am cery sorry the previous owners used a material you do not approve of, i wish i could afford to replace them so that you would be happier.

Thanks. I will pick up some solvent based tomorrow.

Typically i had picked up solvent free as the only thing it saod was different was that the solvent one could be used outdoors. ..

Apologies for my earlier comments - I just hate MDF!
As for considering using plasterboard as a shelf, that thought still stands. While you might appreciate its weakness and unsuitability as shelving, you can be pretty sure that someone at some time will put something too heavy on a flat surface consisting of nothing but plasterboard...

Its not the nicest material to use but it has its benefits such as its stable,takes paint well (moisture resistant one) cheap compared to solid timber.

You can get an exterior MDF called Tricoya which is very durable and stable. I put some in a bucket of water for 2 days and it didn't take on any moisture at all or expand... Down side is its about £130 a sheet.......
