It Started With Needing to Fix A Problem
Repairing small diameter plasterboard holes in walls and ceilings is a relatively expensive and time-intensive process usually requiring a professional or competent DIYer, working over a long period of time. The current popular repair options are:
Current Repair Options for Holes up to 150mm in Diameter
Wall Patch – a thin self-adhesive mesh patch stuck over the hole and plastered over. This repair bulges proud of the wall and is easily cracked with a small knock.
Back Block – this method is typically a plaster or timber frame glued from the inside, to which the plaster repair patch is then affixed. It offers better results than the patch but is awkward and requires experience, tools and materials not available in small quantities. Not only does this technique require several layers of plaster and 24-48 hours to dry, but most methods also use screws or other metal components which can rust over time – leaving unsightly stains.
Butterfly Patch – more common with professional plasterers, this repair method gives the best finish of the current options, however, requires purchasing tools the average DIYer will not own (large diameter hole saws) and plasterboard/drywall repair panels.
Despite the poor quality and extra manual workload, professionals and DIYers continue to use these methods, as there are no better offerings on the market.
As a result, tradesmen and builders are either leaving poorly repaired holes in walls or leaving other jobs to go back and put extra layers of plaster over the holes the following day, taking time out of jobs and passing the cost onto clients.
