BAL Bond SBR on plasterboard

[markdraper]

This is my first major tiling job in the house, so I am after some advice please.

We are looking at re-plasterboarding the kitchen walls, as when the old tiles came off, there was a big mess on the existing plasterboard, which I assumed there would be, so I am cutting out the old and replacing it.

I went to a tile warehouse store and found some tiles we liked. They are 40cm x 25cm tiles so large sized. I asked them their advice, and I am not sure it's right, by reading some threads on here.

My question is, after replacing the boards, they said that I need to use BAL Bond SBR on the plasterboard, before tiling on the board, to prime it. Is this the right stuff to use. It was expensive and looking on posts here, I am not sure it's right.

If it is right, is this correct procedure.
1) tape up the joints
2) use jointing compound, to fill in the gaps
3) mix up the BAL Bond SBR, brush it on
4) then tile once it's dry

Any advice help would be great.

no need to seal the boards imo ,something i have never done

 

[markdraper]

ok, do I need to seal the boards if I were to paint them?, as I am doing that on one wall.

Also, is taping them needed, will it add any strength for the tiling, or only needed if it's being painted?

 

[Brian the Tile]

dont know about the paint ,taping the joints will do no harm though ,the main thing is to make sure there is no movement in the boards when fixed

 

[Brian the Tile]

just to add to that tiling is a trade that looks easy when you see a tiler doing a job, if its your kitchen which will be seen by others would you not be better getting a good tiler in as usually a tiler will have the job done while you are thinking about it ,just a thought

 

[markdraper]

I will make sure there is no movement, the wall, we are tiling, isn't big anyway, just under the kitchen cabinets.

We have all the materials, so just a case of doing it now.

Do I take back the BAL Bond, as not using it on the tiled wall!, but what do I need for the board that will be painted?

 

[Brian the Tile]

i think the paint job ,you will need to ask a painter,but i would have thought if you dont seal it the plaster board will keep drinking the paint

No need to SBR bare plasterboard but for painting bare boards it's best to roller on a mist coat first - very diluted emulsion (assuming you're using emulsion?).
Can't say I've ever painted bare plasterboard before but I guess it will help, same as if it were plastered.

As the lads said no need for bonding as long as the boards are fixed well and as for painting them I've done dry lining and to get a proper pro finish you need rounded edge plaster board then tape the joints smooth over with jointing compound when it's dry sand it down then dilute the paint and mist coat it

If you are to paint over new plaster boards then you should use a drywall sealer.
A lot of people try to use a diluted coat of paint as a mist coat and most of the time you will get away with this.
Dont use Bal sbr as a sealer for paint unless you are going to use latex paint.
Use any drywall sealer, quite cheap and saves having to apply several extra layers of paint to cover plasterboard.

You should use this before decorating Gyproc Drywall Primer

What about painting over plaster?
What primer would everybody use or would you just use a mist coat?
I've always just used a mist coat but wondered what the right way to do it was?

A mist coat is all you need for paint....

I use a drywall primer on certain walls but find the finish isn't as good as using a sealer.
I find Primers are great at covering up inperfections in drywall but leave a mottled finish
But on new drywall,I find painting over sealer give you a glass like finish.

It's because of the texture of the tape joints, if you paint straight over the joints stick out like a sore thumb...

The texture of the taped joint has nothing to do with the with the finish, painting over primers achieves.
painting over primers give an inferior end result to sealers.
You can paint over drywall primers but the finish will not be as good as using a sealer.
You really can tell the difference the shinier the paint.

Quote from British Gypsum; A general purpose plasterboard primer. The product provides an ideal surface for decoration with most paints and wall coverings.

If you seal it then theres no [FONT=Arial, Tahoma, sans-serif]absorption into the plasterboard because of the shiny surface, the paper surface of the plasterboard has a different absorption than the joint filler.[/FONT]

I think were splitting hairs now.
Both will work, I use a lot of bathroom paints which tend to be shinier than normal emulsion, and I really do see the difference. Next time you paint just give sealers a go, see what you think.
Going to have a look at what British Gypsum they say about sealers.

 

[thompsonbrown]

Reading there product info you may be right.
Need to read more.

Your probably right, either one will do the job and BG move the goal posts as they seem fit at time especially there Thistle Uni-Finish but thats another thread.

seems to be more duel primers & sealers
Used a sealer when my Mrs spent over £300 on farrow & ball paint for our sitting room. what a finish it has.
Can't believe i'm serching paint primers and sealers at this time of night.
Ive forgot what the hell this post was about.

Heard good stuff about their paint....not cheap though.

 

[thompsonbrown]

Its about £50 a 2.5l tin but it is the best paint ive ever used.
They also still make paints with lead in if you can believe that.

Can't see that happening with the EU directive, last time I used lead paint it took us half an hour to mix up....
