MR GRAHAM BIRCH

HIYA ROBSAN,

(1)WHO TOLD YOU THAT YOU CAN'T PLASTER IT!IT DOES'NT MATTER WHICH WAY IT HAS BEEN PUT UP,ITS THE SAME ON BOTH SIDES APART FROM THE PRINT.
(2)IF YOU DECIDED TO PAPER IT YOU FIRST MUST SEAL IT BECAUSE THE PLASTER BOARD WILL ABSORB THE PASTE.TO SEAL IT,APPLY SEVERAL COAATS OF WALL PAPER PASTE OR MAYBE PAINT ITB BEFORE YOU APPLY THE PLASTER.(MAKE SURE ITS DRY BEFORE YOU START.
HOPE THIS WILL HELP YOU.
GRAHAM.
