Personally, I think this step is usually unnecessary, however, if you're working with a more porous surface or a surface that will struggle to accept paint, sanding and applying a second coat of primer can ensure that your paint will really stick. So, if you want to sand over your first coat of primer and add a second coat, go ahead and do that now.
Then repeat step 2 and move on to painting once it's dried again. If, however, you don't feel the need to sand down your primer, go ahead and move on to adding coats of paint to your newly primed surface. Now that we've gone over some of the basics about how to properly apply primer and let it dry, you should be prepared to make your next DIY project or paint job a huge success.
So, no matter how many coats of primer you decide to use, make sure you're letting it fully dry before moving on to your first coat of paint. Check out some of these other helpful guides to help you nail the perfect paint job!
Repainting your exterior, but annoyed with all the previous paint that is peeling off? Are you looking for the perfect paint primer for your bathroom ceilings? By Pro Painter Madison Rude. Last Updated On October 15, Are you wondering how long you should let that primer dry before you paint over it? You've come to the right place! In this ProPaintCorner.
There are three distinct time frames to be aware of when interior painting with water-based acrylic-latex paint or oil-based paint also known as alkyd or solvent-based paint. Paint dry time is the period of time that it takes for wet paint to become tack-free and dry to light contact. Sometimes, paint manufacturers refer to this as "dry to the touch. For purposes of recoating, dry time is deceptive. It's easy to believe that if the paint can be touched by fingers, it can be touched with a paintbrush, too.
Paint recoat time is the period of time that it takes for the paint to be thoroughly ready so you can apply another layer of paint. This can be as little as 30 minutes for flat latex paint to nearly 3 hours for a glossy paint. Paint cure time is the time it takes for the paint to fully harden so it becomes washable and more touchable. This can sometimes take weeks, depending on the season and your climate. You don't have to be concerned about a paint's cure time when it comes to recoating.
Stay within the following margins of dry and recoat times for both water-based and oil-based paints for a smooth, flawless finish on your interior walls, trim, and cabinetry. Water-based paints always will dry considerably faster than oil-based paints. That's because the water in latex paints evaporates to let the paint dry, and there's no water in oil-based paints.
Paint has binders in its formulation to help hold the pigment together. Flat paints have the least amount of binders and glossy paints both water- and oil-based have the most amount of binders. The binders in the formulations translate into drying time.
On the other hand, an oil-based primer will need a longer time to dry out. If you have time, I advise you to always give a primer at least 12 hours to cure, no matter which type it is.

Always double-check the spray paint and primer labels to make sure. Automotive painting varies from other projects. Primers are important undercoats because they fix unlevel surfaces, providing a smooth surface. They also hide and prevent rust or corrosion. Most primers should sit on a car for around 24 hours before applying the base coat of paint. Some primers may dry in as little as 30 minutes, but experts say to apply the primer 24 hours before painting for the best results.
Although each primer has a standard time to sit before you paint, some factors alter the duration. In some circumstances, the primer may take longer or shorter to dry. Consider these factors to save time with your painting project. Temperature and humidity are the two biggest factors in the dry time.
The hotter and more humid your area is, the longer primer takes to dry. Painting in a hot or humid environment could require more time for your project. Low temperatures of around 74 degrees F, on the other hand, allows more primers to dry in about an hour. Maintaining an equal temperature is also ideal. When it comes to humidity, maintain low levels.
Dust and debris can get into the primer as it dries, causing more issues. This is a massive reason why you should paint over a primed surface immediately. The longer you wait for the primer to dry, the most likely it is for dust and debris to accumulate on the surface. When dust or debris sticks to the primer, it causes the painted surface to have an odd texture. You want to clean your work area before starting and always wipe off the primer surface with a wet towel before painting.
Ensure all loose dirt is gone. How you apply the primer and paint could also affect the dry time. If you thin a primer to apply it using a spray gun, the process is shorter. Spray painting also tends to apply the primer in thin layers, which speeds up dry time.
Consider your environment first. Primer tends to dry faster at low humidity. Lowering the humidity level allows the water in the air and your primer to evaporate quickly.
