A Chalkline is made up of a string or line, coated with colored chalk. It will transfer a straight line to a working surface easily and accurately. It consists of a teardrop-shaped chalk box filled with colored chalk, a mason's string, and a handle on the side of the box for rewinding the string (line). You can buy powdered chalk at the tool shop to refill the chalk box.
You will need to pull the line out and hold it tight between the two points of measurement then snap it to leave a mark. Some chalklines have a pointed case to double as a plumb bob.
It is a great tool when you need to mark a straight line, whether you are creating a design you plan to paint or need to cut wood or wallboard.
Here are some quick tips that will help you keep things straight.
Usually you need another person at the other end of the chalkline. But if you are working alone a temporary nail can be your best friend. Simply tap it into the spot you want to set your chalk line and hook the chalkline to the nail.
One problem with chalklines is that the line often leaves a heavy layer of chalk dust, and the chalk is messy. It can get on your clothes, hands, and materials where you don't want the chalk dust. If you leave excess chalk on wallboard, for example, it may be picked up in your latex or other paint, and be carried all over the wallboard surface by the paint roller. Or, if you use the chalk line to mark the walls for installing a suspended ceiling, you will most likely get the chalk on your hands and spread it over the acoustic ceiling panels. So here?s another tip. Before you ?pop? the line to leave your mark. Pop it first away from your project, that way the excess chalk dust won?t get all over the area you want to paint or cut. You can also take a new chalkine, one that doesn?t have chalk in the case. In an area away from your project coat the line or string by hand, but only coat the length of string you need to mark your line. This will help keep
