Frequently Asked Questions

When should I use yellow marking chalk?

Yellow is the best colour when you are marking on dark surfaces or working in low light. White and blue chalk can disappear on dark concrete, asphalt, dark sheet metal or timber, while yellow stays visible. It is also handy for showing a layout change or a correction over an earlier line.

How long does the line last?

The listing gives a weatherability of about 1 week for the chalk line. That means the line stays visible through normal weather for around a week, which is long enough for most layout and marking jobs. Heavy rain or foot traffic can shorten that, so it is not a permanent marking product.

Will this chalk work in a chalk reel?

Yes. The 226g bottle is sized to refill a chalk reel, and the chalk is a line marking grade that flows through the reel and snaps onto the surface. Use a reel with a good string tension and a straight pull for the cleanest line.

Is this chalk suitable for indoor work?

Yes. The listing states indoor and outdoor applications. On indoor jobs it is useful for marking layout on floors and walls before setting out, and the yellow line is easy to see on most surfaces. The chalk wipes or brushes off surfaces after the mark is no longer needed.
