Reddit mentions of Discovery Sidewalk Outdoor Chalk Paint

I’ll do you one better... instead of tiring out your arm using sidewalk chalk sticks, just roll it on with a paint roller... With the sidewalk chalk, they sell for kids a sidewalk chalk that is ground up into a fine dust that you add water to and then the kids “paint” that wet sidewalk chalk on to the ground with paint brushes and rollers. It’s still sidewalk chalk but your applying it like a paint, our kids like playing with that more then the sidewalk chalk sticks. Anyways, buying the powder kind that you paint on to ground is expensive but you can buy 100 sidewalk chalk sticks super cheap. So what we do for our kids is I run over the sidewalk chalk with my car tire to break it up (put it in a ziploc bag before squishing with your car). Then buy a super cheap blender at thrift store or cheapest one from Walmart and use the blender to grind it up into fine dust. It’s more steps but then you can have the paint on version of sidewalk chalk for the same price as regular sidewalk chalk.

This is the chalk “paint” that you can buy that I was referring to as being expensive that is just a fine chalk powder: https://www.amazon.com/dp/B074FX5W7K/ref=cm_sw_r_cp_api_i_H1CiDbBMA8BKA

Or just saw this online you can also get chalk in a spray can form that would be quick to use on fireplace but might not work well as rolling it on with a paint roller. https://www.amazon.com/dp/B01HDYBMYS/ref=cm_sw_r_cp_api_i_w0CiDbQWRR8FR
