Blue grit.

[Jase]

Hi people got to board kitchen and bathroom with pink and green plaster boards. Is it correct these have to be primed first with pva mix or blue grit or simular products? Before skimming?   Many thanks, regards jason.

Missing sentence.

I used Gypsum contact adhesive on moisture boards for years Blue or green grit The last three or four years It’s stoped appearing in the bill of quantity So no Skim or tile directly onto your green boards

I found blue grit a pita to use. I tried on some green mrpb here despite everyone telling me not to bother!

 

I skimmed straight on the board.

I had years of having to supply it 

We still use it for skimming directly onto concrete

Would you scrim the boards joints b4 putting on the blue grit or after?. Cheers jase.
