How to use a spirit level
However big or small the job, level is important. This ranges from putting your refrigerator into service to hanging a picture and is a skill not only required by the workman, but by the lady of the house as well. This will help to be able to achieve level placement of items within the home, as well as gardening projects. A spirit level works on the basis of presenting a bubble. This bubble shows how off level any item is whether it is horizontal or vertical. This really does help to determine where even the first piece of wallpaper needs hanging and is something everyone should be aware of.
Decide where the line needs to be.
When measuring for level, decide where the line needs to be struck. In the case of wallpaper hanging, the line would be vertical. The difference between vertical and horizontal is easy. Think of the word «horizon». The horizon follows a straight line from right to left just as in nature. A vertical line runs from top to bottom. In the case of wallpapering the line for the main wallpaper would be vertical, while the border level would be horizontal. Decide where you are going to start wallpapering, as this will determine where to mark a pencil guide line. Similarly for all horizontal measurements, the system is the same.
The bubbles used to measure the vertical are usually found at the top of bottom of the level. Hold the level against the wall, or whatever surface you need to measure, and look where the bubble falls. There are two central markings on a level. When the level is correct, the bubble should fall directly between these two markings and be central.
Marking the level.
In the case of needing to mark the level, take a pencil and mark along the edge of the tool itself. One thing to be aware of is that often the edge of level has little slots for the horizontal bubble area. Try to use the straight edge of the level for all markings, even if this means turning the level over to use the other side.
Marking the horizontal lines.
In a case scenario where you want to hang something horizontally or judge the level of an appliance, use the level holding it from left to right, with the bubble on the top of the level. Move the level until the bubble appears in the center of the markers shown. Mark these lightly with a pencil if needed.
Laser levels are more complex, though the principle of these is to cast a vertical or horizontal line on a surface. These can be used similarly, although the traditional level is much easier for the amateur. On a similar principle, a bubble appears which needs to be centrally located and once you have found this position, turn on the light beam. This allows you to visualize the line needing to be struck and to pencil mark the line. The problem with these is that often the line is too thick for accuracy of marking and if found to be the case, the traditional level is the better option. In large areas this is hard to use, since the laser level needs holding in place while marking, and would mean to two man job.
Choosing a level.
Try to avoid buying cheap levels. A good quality level will give years of reliable service.
