Contractors and DIYers, this Keson chalk dye is the real deal for making crisp, long-lasting layout lines! Unlike regular chalk that blows away or washes off easily, this premium blue dye lays down a brilliant line that stays put even in challenging conditions. The water-resistant formula means your marks won't disappear if they get damp, and the color is vibrant enough to see clearly on most surfaces. You get about 12-15 solid lines from each 5oz bottle, which is pretty impressive longevity. The flow is smooth and consistent, making it easy to fill your chalk line box without clogs or mess. Whether you're framing, doing concrete work, landscaping, or any project that requires precise layout lines, this chalk dye delivers professional results. Keson is a trusted brand in measuring and marking tools, so you know you're getting quality that professionals rely on daily. If you're tired of re-marking lines because regular chalk faded or blew away, this dye solves that problem completely. It's one of those simple upgrades that makes a huge difference in efficiency and accuracy on the job site. The blue color shows up well on various materials, and the weather-proof properties mean your marks will be there when you need them hours or even days later.
