Don’t let the wrong chalk ruin your project 👎 #chalkline #learn #stains #deck #siding

This chalk can leave permanent stains on your house. There is not just one color of chalk line. They all have varying levels of resilience. The material from which the line will be drawn determines the color of chalk you should use. Red and black chalk are great for places where you don't want it to wash off. And blue or purple chalk is best if you need it to be washed off. This can be found out by the numerical scale on the bottle. Depending on the quality of the chalk line, some can leave clear lines, while some release much more chalk. So if this chalk gets on your siding or all over your patio, it may need to be replaced.
