Plasterboard up - What now??

mac123

Hi

I've just put up my new plasterboard in my kitchen as i took it all off as when removing tiles, chunks were taken out of the wall!!

The board will be covered by units and tiles but there are some areas where i need to paint it to match rest of the room.

BTW it's b&q gypsum board and is brown on one side (and it says 'plaster other side only') and the other side is greyish!

Do i need to do anything before i paint the wall and also what side do i paint?

Also, finally how do i fill the joints in between the boards??

cheers

Plasterboard Joint Tape

As for which side you paint, if you've already put it up it's the side that's exposed

Ideally you'd be plastering the board first, but if you're going to paint directly on to it, then you'll need to prime first. Either use an all purpose primer, or diluted emulsion for the first coat.

You could also use diluted PVA.

You can get primer specifically for the job of sealing plasterboard, but it'll probably work out more expensive than the other methods.

Going on that information I would suggest painting the side facing into the kitchen ????????

NO NO NO No and NO. Never put PVA on a surface your going to paint. Just apply a watered down emulsion paint.

As to the joints depends whether you used square edged or tappered edge. Having brought it from B&Q I suspect it will be square edged. Both methods would be the same but the effect would be totally different. Apply jointing tape over the joint (I prefer the open mesh type) then cover with jointing cement ?? (think thats what its called). With the tappered edge board you will get a nice flat finish. With the square edge you will end up with a bump which means that you should then get the wall skimmed.

hiya mac,
i'll be redoing the bathroom soon and know i'll make a mess of the walls ripping tiles etc off. i was going to get a plasterer in to make good after the suite is fitted, then tile the minimum amount possible. anyroad! how hard was it to plasterboard? and are you happy with what youve done, or given the chance would you call in help?

Hi ABN, am a little curious as to why you should say not to apply PBA to a surface that you are about to paint?
We have just completely renevated our house over the last 3 months, requiring almost every wall and ceiling to be re-plastered. I have apllied PBA to all of them prior to painting due to the walls being bone dry and found it to be the only way to get a decent finish.
Hope this doesn't come across as being argumentative, just curious as our plasterer advised the opposite.

Tried searching the net to find te definative answer and was surprised how many links I could find that did recommend sealing plaster with dilute PVA

Perhaps thats how/why the mistake has grown.

But I can assure you that emulsion paint will NOT stick properly to PVA is a similar way that it won't stick to gloss paint either.

This thread I think sums it up better than I could

Would heavy duty lining paper, or two layers of medium/light paper hung alternate ways, be good enough to give a smooth surface for painting or would the joints show through?

I’m asking the question of the experts on here, not recommending this method.:D
