I am plasterboaring a exterior door and window recess that now falls inside a conservatory. Need some advice. The top of the door and windows where I need to put the plasterboard has the metal flat lintels that look something like the pic below. Question is can I drill pilot holes in this and screw the plasterboard to it or shall I use some sort of glue?
Also the side of the recess has bricks. What kind of caulking glue can be use to stick the plasterboard? Can I use regular forget nails instant grab adhesive?
