Hi all
I removed some tiles from a wall. The wall is 12mm plasterboard dot- and-dabbed onto breeze blocks. In most places the tiles came away cleanly but in one area the tiles had been stuck down very firmly. Having removed those tiles I now have a 3 x 3 foot section where the wallboard is more or less destroyed (breeze blocks showing in places and any plasterboard that is left is very weak). I am thinking of cutting out that 3 x 3 foot section of plasterboard and replacing it with a new piece. I think the plasterboard adhesive comes in 25 kg bags which would be overkill for this sort of job. Is there something else I could use to glue the plasterboard to the breeze blocks? (Gripfill?).
Can anyone advise me how I make the joint between the new and old existing plasterboard? I think it involves tape and Easi-Fill? -do you fill the joint with Easi-Fill, tape over the joint, apply Easi-Fill over the tape and then sand it down when dry? Or are Easi-Fill and tapes two alternative methods and you use either one or the other rather than both?
thanks in advance
Julian
