how to fit wall units onto plasterboarded wall.

irishjohn

If you have not already bought the wall units - or if they are in a returnable condition, maybe reconsider - if enough concealed storage in floor cabinets then consider open shelves instead of units on wall

Why is it assumed there is a studwork frame? could it not just be dot and dab?

Balance of probablilty. As SCRGI has noted its 7 cms from the wall to the plasterboard. An 8 x 4 sheet of PB requires a bag of PB addy to fix it to a wall properly just a cm or so off the wall. To fix it 7 cms off the wall you would require a mahousive number of bags at enourmous expense and it wouldn't be stable whist the addy was curing and levelling up the boards would be challenging to say the least with that amount of sloppy adhesive behind each one. Let alone the time factor in doing it. Frankly its just not common sense and not particularly intelligent either. Ahh, well I suppose there is a possibility you could be correct then.

Back again. Some interesting comments above.

I still would be looking to try to see of there were any studs holding the plasterboard. You can locate them with a stud finder - although if you don't know what that is, maybe Steve the fitter is right that you need some professional help.

If you do find studs there, you can mount the wall plate through these with long expanding screws/bolts into the brickwork. That would solve the problem of the mountings bending, and also give you a super-secure load bearing fixing. If you make the wall plate with a chamfered top edge, and put the chamfer facing the wall, you can then fix another plate with an inward facing chamfer on the bottom edge to the units, and simply hang the units by this onto the wall plate. The 2 chamfers marry with each other and hold the units secure and up. Yes, they hang away from the wall by the thickness of the plate, but you can easily pack out to sort this. This method also allows you to position the units laterally wherever you want - you're not governed by the stud / fixing positions. Just position the wall plate where you want the run of units.

It may sound complicated, it's not really for anyone with a bit of diy experience. When I stripped the old units out of my kitchen in a previous house, I found this was how they'd been (professionally) mounted.

That's a neat idea although I suspect you mean "top edge" rather than "bottom " on the wall units

If there's a 7cm gap, chances are there are some studs onto which the plasterboard is anchored. If you can find them, you can fix a longitudinal plate along the length of the wall units by screwing into the studs, and hang the units onto this.

thank you bob!
but could you translate it to "blond language" please.

with a 70mm gap the plasterboard is almost certainly fixed to 50 x 50 bits of wood (studs). These will be vertical and about one every two feet.

What Bob is suggesting is you locate these studs and then fix a pair of horizontal battens to them. These horizontal battens will then give you a secure fixing for your wall units

Neat yes but you have to be spot on with mounting the top batten on the wall cab. There is zero room for adjustment with this method. Its also going to push the wall cabs further out into the room thn the 3 or so inches OP has already lost.

I still think they should start again.
