A LITTLE ABOUT PROCHALK- ALL MARKING CHALK IS NOT CREATED EQUAL
Keson is the only company making marking chalk in the United States. We have formulated our colors
to meet the diverse needs of our customers. The color and the amount of the pigment determines the
vividness and permanence of the line. We believe we have created the best marking chalk in the world. It
sticks to your line until you decide you want it to stick to something else. Over the years, we’ve fine-tuned
our formulas to produce chalk that performs with consistent excellence, batch after batch.
FIVE LEVELS OF INTENSITY
We’ve engineered a range of colors with five variations of intensity.
ProChalk Standard for your basic chalk line needs that are easier to clean up or let wear away naturally.
ProChalk High Visibility which include our Glo-Orange, Glo-Lime and Yellow formulations for highly
visible applications that will wear or wash away naturally in a few days.
ProChalk Semi-Permanent for weather- and
water-resistant lines that hit and stick for a long time
but will eventually wear away naturally.
ProChalk Permanent for weatherproof and
waterproof lines that aren’t going to go away any
time soon. Most users are choosing this level of
intensity for applications that are going to be
covered. This level is engineered for more extreme
conditions.
ProChalk Ultimate Dye which is almost 100%
pigment for lines that are intended will be laid down
once. Period.
