Prevent Skinning Paint
Those who like to do DIY projects around the house might be a little familiar with skinning paint. It’s what happens when builders leave cans of paint a bit open for a few days. The paint will solidify, causing a mess and sabotaging your next paint job. If you’re faced with this, just cut some foil and put it in the can. Blow some air into it while you close the lid of the paint can – the carbon dioxide from your lungs will prevent oxidation!

Random painting fact: When the White House was first painted, they used a lime-based whitewash that was meant to weather over time. It limited the white look to only cracks and crevices. The whitewash wasn’t meant to weather, however as it was periodically re-painted.
