"Question 1, why do you want to seal the green plasterboard, for what?

Question 2, yes you can use green plasterboard to join with normal plasterboard as long as It's the same thickness."

"However, Plasterers use it for different reasons. The other main function of PVA is that it's used as a primer. We seal all the walls with PVA (not needed on plasterboard), to make sure we can get a decent finish. It helps bond the plaster to the walls and also gives us time."

"Yes if using as a primer let it dry overnight, and as long as the existing board is the same thickness eg, 12.5mm to 12.5mm it will be fine."

"Green plaster board is moisture resistant .i would not recomend joing green to normal in any showers or other wet areas . Unibonding green is not necassary as its allready treated as moisture board .but wont hurt it .it will make tileing more difficult as the tiles will slide"
