Do You Have To Put A Sealer On Chalk Paint . I do have a few pieces on my blog that are milk painted but i didn't fall in love with it. I use the wax for sealing or chalk painted items.
Find a can of clear wax sealer from the hardware or paint store. Do i need to use a bonding just keep in mind that the paint is very thick, so you may or may not have to repair chips beforehand. Very good point about the preparation of what you're painting versus the finishing you have to do with chalk.
If you do go in a few different directions, just brush over the area in one direction to even it out.
Chalk pastels are easily smudged and have to be fixed immidiately or put under glass in order to protect the painting. I've only ever used poly or spray on sealer. Chalk paint promises that you'll never need to sand or prime your projects, but sometimes that's simply not true. But i've used a matte poly sealer on a coffee table to guard the surface better.
