Jase Posted March 27, 2021 Share Posted March 27, 2021 (edited) 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. Edited March 27, 2021 by Jase Missing sentence.

nod Posted March 27, 2021 Share Posted March 27, 2021 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 1 Link to comment Share on other sites More sharing options...
Onoff Posted March 27, 2021 Share Posted March 27, 2021 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. 1 Link to comment Share on other sites More sharing options...
nod Posted March 27, 2021 Share Posted March 27, 2021 I had years of having to supply it We still use it for skimming directly onto concrete Link to comment Share on other sites More sharing options...
Jase Posted March 27, 2021 Author Share Posted March 27, 2021 Would you scrim the boards joints b4 putting on the blue grit or after?. Cheers jase. Link to comment Share on other sites More sharing options...
