Newly drylined and skimmed bathroom

[pandabear]

It's my first post here so a big Hi to all of you!

I am looking for a little advice, we are about to start a bathroom install in a loft conversion which has been drylined. The external wall was dot and dabbed with the internals and ceiling screwed in place. The room has been skimmed over the past week.

So the question is, is there a recommended time after skimming that we should wait before tiling the walls? It is likely be at least two weeks after the skim before the bath and pan connector are in situ, are we able to start tiling immediately afterwards?

Your advice is most welcome!

Thanks in advance

Yeah couple of weeks will be fine skimmed plaster board doesn't take long to dry out and use a primer before you tile. oh and welcome to TF.

a couple of weeks this time of year will be fine.
what tiles are you using? just asking because you are tiling onto skimmed boards. just thinking of the weight thats all.

Hi and welcome....

As above, just to add un-skimmed plasterboard will take more weight than skim, make sure you prime with SBR not PVA. Good luck.

Hi, some more info on tile choice would be great.. is there a shower in situ as well.?

if its plastered, bs say 28 days, un plastered (dot & dabbed ) 10 days and screwed , you can fix to aslong as they have used proper support

I have never screwed dot and standard plasterboard, thermal boards yes...

british gyspum recommend screwing plasterboards when fixing large format or stone to dot and dabbed plasterboards. allow the adhesive to dry and then screw through the dots and 5 per meter. they also recommend 7-10 days for the board adhesive to dry and set prior to tiling.
seems like a day doesnt go by without something changing in this industry, its getting hard keeping up!!

Thats a new one on me Ed....

 

[tilerjason]

That's british standards for you lol

They also recommend 1 bag of dry line adhesive for 1 8x4 board , fixed with 12 dabs and 12 screws hence the phrase dot and dab , dots Being screws and dabs being adhesive

 

[strummerman]

i wonder why

 

[White Room]

An 8 x 4 board is 2.88 m2 and BG recommends on 4-5m2 for a bag of adhesive...a whole bag of adhesive on one board, thats ridiculous.

 

[Aston]

i like your style jason. lots of problems waiting to happen regarding tiling on dabbed boards!! many people i see dont but enough dabs behind the board and along the ceiling lines etc..anyway, the more we share the more we learn.

 

[White Room]

But not a bag a board Ed...and 12 screws for each board, if the tiles are that heavy they should'nt be fixed to gypsum anyway for heavans sake...

 

[Aston]

sorry beam when i said i like your style, i meant the belt and braces approach.
to be fair i always thought it was 8 per board, 3 down the side and 2 down the middle so so to speak as for a bag per board, i was never aware of that myself but i am aware that people dont run a full line around the perimeter of windows, sockets, ceiling lines and internal angles..

 

[White Room]

Especially on exterior walls as you say to stop any airflow....

Well you learn something everyday. I thought dot was the adhesive and dab was the action of dabbing it into plumb with a straight edge!!! haha - Not sure why though, nobody's ever actually explained that - I just seemed to have that in my head for some reason.

A whole bag per board, and then 12 screws too? Makes you wonder why we don't just render it! Though plasterboard was the 'quick and easy option'!

 

[strummerman]

its all just to keep tilers happy full of of female hormones and that :lol:

 

[White Room]

The dots are the adhesive and dabbing is the fixing of the board......

Tilerjason said at the end of this post:http://www.tilersforums.com/tiling-forum/59557-newly-drylined-skimmed-bathroom.html#post612903

That dots were the screws and dabs were the adhesive.

Though I thought like you that the dots were adhesive and the dabbing was the term for fixing them to the wall in general.

 

[White Room]

Screwing is somethink I'v heard recently for standard boards,thermal boards are a different issue, extra dabs should be applied where fixings, sinks, radiators etc are being fixed/screwed to the walls...if the screws heads break the surface on the paper facing they are next to useless anyway....I learnt with British Gypsum in 1999 perhaps I should be asking for my money back I've been doing wrong all these years.

 

[AliGage]

I thought the same as you Dan. The dot and dab bit.
If a board required a stronger fixing (i.e screws) i'd build a timber frame on the block work and secure the boards.
