Age, subsidence, incorrect application and various other factors can cause plasterwork to be damaged over time. This can leave very unsightly cracks and holes within your plasterwork which are very difficult for a DIY’er to repair. However, many people give repairing plasterwork a go and, with care and the right tools it certainly is a very accessible job to do yourself. It depends on the size of the hole or cracks as to whether it’s something you should try yourself. Also, whether the actual plasterboard is damaged so much that it needs replacing.
If plasterboard has got damp due to a burst pipe or overflowing bath or sink then it quite often requires cutting out and replacing and then re-plastering and re-painting in order to get an effective repair. However, if the plasterwork has just sustained a small hole or gouge, maybe due to someone punching a wall or being clumsy whilst carrying something heavy, then it is possible to buy pre-mixed plaster repair kits and have a go and repairing it yourself.
