Before applying the second coat, allow the first coat to dry completely to the touch.

Wait 24 hours after priming before continuing with the process.

Oil-based primer shouldn’t be used on drywall. Instead, choose a latex or water-based primer.

Primer that is oil-based creates more harsher fumes, making it unsuitable for indoor use. Therefore, while using oil-based primer to spot-treat stubborn stains in your home is acceptable, avoid using it on expansive surfaces like a wall or ceiling.

LAST THOUGHTS Oil-based primer does an excellent job of protecting wood and preventing stains. However, a water-based primer is the way to go if you’re painting drywall.

Water-based primers are designed for indoor use and don’t release as many volatile organic compounds into the air as alternatives that use oil.
The good news is that latex paint can be applied on top of oil-based primer wherever it has been applied.
