Paint doesn't cure, or reach maximum hardness, until days after the paint is dry. How long it takes to cure depends on the type of paint: Oil-based paints - about 7 days. Latex paints - about 30 days.
You can still get a little bit of sticking, which is the difference between dry to the touch vs. cure time. Manufacturers will typically say that a paint will dry on average in about an hour but in reality it's going to take 30 days to cure and reach its full optimum hardness.
Applying the second coat too early will result in lost time, money, and effort. Not only that but it'll also create additional stress that's not necessary. Applying the second coat too early will result in streaks, peeling paint, and uneven color.
But if you press a fingernail into the painted surface, a dent may be left behind, and washing, wiping, or exposure to water may damage the paint. Curing: When you can wipe or wash the paint surface without damage and the paint stands up to minor scratches and bumps, it has fully cured.
When it fully dries (about 4-5 days) the tacky goes away.

After taking care to protect any unpainted surfaces, spray some white spirit onto any parts that don't seem to be drying. The white spirit should provide the oil-based paint with the solvent it requires to dry.
For Sherwin Williams and Benjamin Moore paints, the curing time varies based on the paint type and environmental conditions. Generally, exterior paints take around 30 days to cure fully, achieving their maximum hardness and durability.
Paint Curing Process Overview:
Use high velocity air to speed up the curing process by removing evaporation barriers. Avoid thinning the paint by using a plural component pump and an in-line paint heater. Warm the product before applying the coating to increase curing speed.
Water-based paints generally take four hours to dry, while oil-based ones need a full day with open windows providing ventilation. If you have allergies or other respiratory issues, it doesn't hurt to give the paint a couple of days to fully cure before snuggling up in your freshly painted room.
Recoat Time for Oil-Based Paint
Water-based paints dry considerably faster than oil-based paints because the water evaporates to let the paint dry. Oil-based paints contain no water. Though oil-based paint may feel dry after only a few hours, it's best to wait a full 24 hours or more before applying additional coats.
The Walls Were Not Prepped or Primed Properly
Sometimes, paint streaks aren't caused by poor technique, inconsistent coverage, or too much paint. If your walls aren't prepped properly, then the paint might have trouble adhering to the wall's surface. This can lead to clumps, drips, and paint streaks.
Oil-based paint: 6-24 hours to touch and 24-48 hours to fully dry. Latex paint: 1-6 hours to touch and 24 hours to fully dry. Enamel paint: 4-8 hours to touch and 24-48 hours to fully dry. Chalk paint: 1-2 hours to touch and 24 hours to fully dry.
Children, pregnant women, elderly individuals, and those with respiratory issues should avoid freshly painted rooms for at least 72 hours. Understanding the time needed to safely re-enter a freshly painted room is crucial for your health and well-being.
To aid in the drying process, you can place your project in front of a fan but be careful not to be too close to disturb the paint. Also, be sure your room is dust free to avoid blowing dust into the wet paint. You can also use a blow dryer, using the lowest speed, and stay away at least 6 inches from your project.
The answer is yes. A fan can help get the air flowing in your painting space. You can use an overhead or freestanding fan to get your paint to dry faster. Just be sure to make sure it's positioned properly.
Mix an equal amount of an absorbent material such as cat litter into the paint can and allow the paint to dry. In addition to cat litter, you can use sawdust, plaster of Paris, Oil-dri, or a product called waste paint hardener which can be purchased at home improvement stores.

A quick an easy way to determine if paint is cured is to press into the surface of your paint with a fingernail. If the paint dents it is potentially not cured completely.
Temperature – the colder the temperature, the longer it takes paint to dry. Humidity – the lower the humidity, the faster the dry time. Airflow – the better the airflow, the faster the dry time. Thickness of paint layers – thicker paint layers will take longer to dry.
Too cold or too humid temperatures. Lack of ventilation. Coating applied too generously. Application of a quick-dry varnish on a different type of varnish.
