There are three types of Keson powdered chalk:
1) ProChalk & ProChalk GLO Standard Marking Chalks: ProChalk is formulated to achieve a perfect line every time. Brilliant color tones provide strong, sharp lines. From the brightest pigments in the industry, we produce standard colors plus our unique, fluorescent Glo-Orange and Glo-Lime for improved visibility.
-4-5 strikes usual line yield
-Brilliant color
-Great flow for easy reel fill-up
2) ProChalk Plus Professional grade marking chalk: There is a delicate balance that needs to be maintained with higher grade chalk: you need enough pigment to slap down a line that’s not going anywhere and enough carrier to keep the chalk flowing. ProChalk Plus is formulated to achieve a perfect, lasting line every time.
-8 to 10 usable lines.
-Brilliant weather-proof color
-Water-resistant lines hold your mark
-Great flow for easy reel fill-up
3) ProChalk Ultimate Permanent Marking Dye: Sometimes called chalk dye, this product lays down a mark that stays. Our red and blue dyes are souped up even more than the ProChalk Plus grades.
-Premium grade marking dye
-12-15 strikes line yield
-Eliminates the need for chalk line saver in most environments.
NOTE: ProChalk Ultimate is PERMANENT, and will be visible for a year or longer no matter how you try to get them off. They will even show through light-colored paint!
