Mistakes To Avoid When Using Chalk Paint
By DEIRDRE MUNDORF
Overlooking Prep Work
Chalk paint can often be applied with little or no prep work, but if the surface is dusty or dirty, the paint won't adhere properly, or debris will show through the finish.
Vacuum off any dust on the surface and use a soft cloth dipped in warm, soapy water to remove dirt or residue. You can also use canned air to blast dust out of nooks and crannies.
When applying chalk paint to a laminate finish or slick surface, sand the surface down to give it a slightly rougher texture, which allows the paint to adhere correctly.
Not Stirring The Paint
As chalk paint sits, whether for months or just a few hours, the ingredients start to separate. Make sure to shake the can well, and stir the paint before and during painting.
If the paint isn't properly mixed before you start working, the consistency and color will be off, and brushstrokes may be visible on the finished surface.
Not Fully Drying Coats
Chalk paint usually requires more than one coat, and each coat must be totally dry. While the paint may feel dry to the touch in 15 minutes or less, it isn't fully dry yet.
Drying times can vary, but you'll know the paint is ready once it has a chalky texture, there is no visible shine, and the paint doesn't come off if you touch it.
Using Too Much Paint
A common mistake with chalk painting is overloading the brush, causing visible brushstrokes and drips that will be noticeable when finished. Apply multiple thin coats instead.
Not Letting It Cure
Painted furniture must be cured before use. Curing is a reaction with the oxygen in the air that hardens the paint, making it more resistant to peeling or getting scratched.
In most cases, it will take about one full day to cure chalk paint, but in some cases, like when humidity levels are very high, it could take as long as two weeks.
