Water has a high heat indexâit absorbs a lot of heat before it begins to get hot. This is why water is valuable to industries and in your car's radiator as a coolant. The high specific heat index of water also helps regulate the rate at which air changes temperature, which is why the temperature change between seasons is gradual rather than sudden, especially near the oceans.
Anyway, I finally bought the chalk paint and clear wax and got started. I did three coats of paint (with at least 24 hours of drying time in between) and yesterday I put on a coat of clear wax (with the uber-expensive wax brush).

Wait 30 Days. New concrete should cure for at least 30 days before being painted, according to Sherwin-Williams. However, even if that time frame has passed, the paint company recommends testing for moisture.Do this by duct taping a 2-foot-by-2-foot piece of plastic to the floor or wall.t's wise to let concrete cure for 60 days before painting, according to the Valspar paint company. After the concrete dries, Valspar and Sherwin Williams both say you should acid etch the concrete so paint will adhere to it.
