Using wall plugs for DIY

  1. 1. Using wall plugs for DIY Wall plugs were invented in 1911 by John Joseph Rawl- ings. His wall plugs were mar- keted under the brand name Rawlplugs, and this name, as a generic term for wall plugs, is still widely used today. Wall plugs are best suited for use on masonry walls. That is walls of brick or stone. They are not the best choice for plasterboard walls. Wall plugs come in various colours. This isn’t simply random, each col- our is a different size and these are standard. For each colour there is the correct drill bit to use for a certain size of screw. The smallest is the yellow wall plug to be used with 6-8mm screws. The correct drill bit to use for these plugs is a 5mm masonry drill bit. The next size up is the red plug, which should be used with a 6mm drill bit for screws of 80-10mm. For screws of 10- 14mm use a 7mm drill bit and brown wall plugs. Finally the largest sized wall plugs are blue in colour, for 14-18mm screws and should be used with a 10mm masonry drill bit. There are plenty of tips for us- ing wall plugs that you’ll pick up along the way. One useful tip, when you’re drilling a hole for your wall plug, is to put your wall plug alongside your drill bit, and mark on the drill bit the length of the wall plug with a piece of tape. You will then know how far into the wall to drill for your wall plug. Another handy tip, if you’re fitting something to a tiled wall, perhaps a towel rail or toilet roll holder in a bath- room; put a piece of masking tape on top of your bathroom wall tiles at the points where you will be drilling. This will give a rougher surface to drill into and should help to stop your drill bit slipping and causing tile breakages or an in- jury. Take it slow. Any drilling task can be dangerous and it’s easy to make a mistake. Debris can easily fly off into your eyes, so do make sure you are wearing goggles or safety glasses while you are drilling, especially if you are drilling through bathroom wall tiles as shards or tile can be particu- larly hazardous. When you’re drilling through plaster into a brick or stone wall, don’t use the hammer ac- tion on your power drill until your drill bit hits the masonry itself as this can cause damage to the plaster. When you have drilled your hole, insert your wall plug and gently tap it into the hole with a hammer. It is best to hammer it until it is just below the surface of the wall. If it is flush with the wall, when the plug expands when you screw in your screw, the plaster could crack and crum- ble. This is less likely to occur if the plug is slightly below the surface.
