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). First of all you donât have to wait that long between coats of paint. Depending on humidity, an hour or two should be enough.
Waiting for a painting to dry thoroughly is less of an issue with acrylics than it is with oils (some experts say you should allow at least six months). If you want to even out the gloss on a not-yet-dry oil painting, use retouch varnish.y Tips on Varnishing a Painting. I used to find varnishing stressful as it is possible to muck it up. My fear was that I'd accidentally go over some varnish that had started to dry and cause it to go cloudy (and acrylic varnish dries very rapidly in a hot climate !).
