Frequently Asked Questions
How to measure slope with a spirit level?
Take note of where the bubble is inside the spirit tube. If it’s centered between the lines on the tube, your object is level. If the bubble is to the right of the lines, your object slopes downward right-to-left. If the bubble is to the left of the lines, your object slopes downward left-to-right.
How to fill a chalk line?
To fill a chalk line, pour the chalk and tap the bottom of the tool against your hand or a tabletop to help the chalk settle. Repeat this step until the tool is full. Once full, extend the line as far as it will go and then wind it back in. Give the chalk line a shake and repeat a few times to evenly coat the entirety of the line.
