Skimming on Fireboard

[marcsouthagate]

Got a job where the customer decided to board up using 15mm fireboards (the smooth grey type) and i'm not totally sure if i need to pva and then thistlebond these or just to treat them like a standard plaster board. Done a bit of a search on here but seem to find various reply's.

Cheers

Sorry misread do you mean plaster boards or similar

They are the grey fireboards 15mm thick. Really smooth to the touch.

Must have cost the guy a bomb, why did he use fireboard out of interest?

 

[marcsouthagate]

They had a load lying round his work he tells me which seems legit enough. Boss said he could have them as they would end up in a skip...

 

[leebo02]

just skimming should be fine

Which make of fire board is grey as I've only come across pink?

 

[johniosaif]

Grey is usually sound board

I thought this as well Andy..

Don't know whether they are but the ones I've been using this week are 15mm grey/white and have fibre running through same as fireline

Sure they're not hardibackers lol

 

[marcsouthagate]

Knauf Fireboard

It's the 15mm type

 

[marcsouthagate]

Irritating part is sending knauf an email about the situation to be told to consult the plaster manufacturer prior to use...

I know which boards you mean ... did a partition in a factory in this stuff . 8x4 sheets ... heavy enough with 2 of you .... used 40 of em in total on that job ... didn't want it skimming though or i'd of been asking does it need priming lol

 

[marcsouthagate]

What a ball ache! I may put a small ceiling on while i screw the rest of the ceilings up seen as he's nailed them up...

Quick update on the fireboard situation. Tried a couple of trowels of multi on the board today and can safely say it's not to be skimmed onto without being primed! It dried the skim out in less than a min. I then tried 2 coats of pva as it dried the 1st out in no time.. to which the skim still dried out at a fast pace. Plan c is now in action, been to tp's and got a tub of thistle bond which i've applied so fingers crossed tomorrow morning it will be good to go.
