http://www.plastermagic.com/how-it-works Rory Brennan, founder of Big Wally's Plaster Magic, takes you through a step by step repair of a hole in a plaster wall. The hole surrounds an electrical light switch box in a house built around 1900. Using a special adhesive, Rory reattaches the broken plaster to the lath behind it. Now stabilized, he is able to apply a special patching plaster and finish it off with a thin coat of joint compound.
