plasterboard question.

[cass]

I have read in to this a bit but who here tapes joints and primes platerboard , so far I havent primed platerboard is this wrong.

 

[Qwerty]

No, not wrong, just not really necessary most of the time. I still prime plasterboard though and did so this very morning!

You don't have to prime plasterboard I don't, but there are always situations where it is sometimes better too.

 

[cass]

Ok depending on situation maybe large format tiles, what about taping plasterboard joints.

I now prime plasterboard as a matter of course.
I use Weber set plus & it states that you must prime plasterboard with PR 360.

I don't skim joints, I just make sure that I run my trowel up the taper so my adhesive is the same depth as the rest of the board.

 

[cass]

Yes I read that about weber gear , do you fill taper as you tile or do you fill first let dry then tile.

I primed & taped plasterboard today........I tend to prime anyway. Had a moment, and taped the joints as well.

Have a bathroom to do next week , 300×600 porcelain think I will prime and tape joints for goog mesure thanks for replys guys

If using a ready mixed dispersion adhesive then I believe it is not necessary to prime plasterboard . However if using a cement based adhesive then the plasterboard should be primed according to all the data sheets I have.
As for taping the joints with scrim, I do because if the tile joint aligns with a plasterboard joint then it will add little extra stability underneath the grout joint

Good point mate good enough reason as any

I fill taper as I tile provided I'm going full height with the tiling.

If its only tiling to say border/sill height then it's taped before I tile. This can lead to a bump on the wall though if its not been taped properly.

Ok steff nice one cheers.

I only prime the exposed gypsum edges on plasterboard.
