CIL has a reputation for amazing paint products, this paint is no exception. I bought a 946 ml can from Walmart for $18 which says it covers a 7 foot square with two coats. I also purchased a large sheet of OSB chipboard from Home Depot for $9 to use as the chalkboards surface. You can buy just regular plywood but it is twice the price as OSB and the only difference is the texture. If you want a perfectly smooth finish pay the extra and get plywood, kids are not too picky about how smooth the surface is trust me.
It took me less than an hour to apply the paint in two coats. It is very smooth, silky, and spreads nice and evenly no matter what level painter you are. I easily covered my 8x4 foot surface with two coats and had some leftover.
My new outdoor chalkboard cost me $35 including the chipboard, paint, and brushes.
This paint exceeds the expectations I had and the kids are going to love it. This week I am also building a canopy type shelter to keep my outdoor chalkboard in perfect shape, safe from rain, snow, etc. So stay tuned to see my next project.
