is it ok to use plasterboard on kitchen walls?

Anyone plasterers out there?
I had to have off about a 1m° at the bottom of the wall due to mould. the depth is about 3/4 inch. As I've never plastered. before important thinking focusing plasterboard and skimming. Would this be ok for a kitchen wall?

Thanks

Is the rest of the wall solid? If so, I wouldn't patch with plasterboard and skim. I'd use bonding to build up the level and then skim with finishing plaster.

The bottom metre is largely behind the units so forget.

But, obviously some will show. It is far easier to bond plasterboard to the wall then skim flush than it is to use say bonding then skim.

Sorry Evoke, but skimming onto plasterboard is so much easier than finishing bottom coat.

^ A future potential issue with that scenario is blown plaster due to different densities behind the skim. I actually have a doorway in the lounge that had been blocked off with plasterboard and then the whole wall was skimmed and then painted.

A year later I have a nice outline of the doorway as the skim has cracked where the different densities join.

Given my experience, i'd always go with the more solid, albeit expensive, time-consuming and difficult job of bonding and skim.

It's a damp area (as there has been mould there) so it's probably best to avoid the possibility of water seeping into a crack in the plaster due to different materials expanding/contracting at different rates.

I had to fork out £300 to get my doorway bricked up and replastered and painted again.

Strange that, I understand what you are saying but if something is "giving" underneath,any finish is going to crack;);)

if it's out of sight, plasterboard and skim. Any plaster type surface will crack if there's still damp behind it.
I've had part of walls built up with expanding foam, pasterboard and skim. You can't tell andit's still intact after 5 years. No damp here though.....

why was there mould on it? from damp or from condensation?

Thanks for your replies. the mould was from condensation. behind the fridge on an external corner. I've had people out to check its not damp and they say condensation.I've hacked the old plaster off up to about a metre and the wall is dry.

You'll just have to take steps to remove the condensation then, and it shouldn't be a future problem
