General Plasterboard Repairs just finished one its hardest job to date. The Gyprock ceiling Repair at the Cheetham Salt Factory on the York peninsula was a challenging but yet rewarding achievement from all the guys involved. The original Gyprock ceiling had been corroded from all the salt the had gathered on the top of the ceiling. Also all the Gyprock nails that were holding the Gyprock ceiling up were completely rusted. The salt the fell from the gyprock ceiling when we were removing it took just as long to clean up as it did to do the job.
