Old paint can often de-laminate over time, which will affect younger coats. The entire surface should be hosed down to get rid of any dust or dirt, then allowed to dry before applying any paint, as even a small amount of dirt can weaken the adhesion and lead to peeling.
Use quality caulk to seal around windows and other gaps. Finally, adding a good primer is essential to a lasting paint job and reducing the effects of weather to the underlying materials, especially wood. No matter how much effort you put into creating a top-notch paint job, there are some factors which are beyond your control. These can often cause a quality paint job to fade or chip in a fraction of the time that same job would last elsewhere.
One of the biggest factors that can reduce the lifespan of your paint job is the location of your home. An arid environment will age the paint much slower than a humid environment, and a location near an ocean or sea can cause a paint job to degrade approximately five times as fast. Weather patterns also play a major role in how quickly a paint job degrades. In regions with mild weather throughout the year, your paint job will last much longer than in a region with heavy snows or harsh temperature fluctuations.
Heavy storms, hail, and frequent violent winds can cause the paint to scratch or blister. Over time, this will lead to chipping, peeling, and fading. While it is unlikely to chip the paint on its own, direct sunlight for long periods will start to fade the paint. This is more noticeable with darker colors than light, and the side that faces the sun will fade faster than the shaded sides of your home. The material you are painting will have a major effect on the lifespan of your paint job.
Wood surfaces tend to degrade the fastest, followed by brick or stucco. Aluminum and vinyl siding can retain paint for 20 years or longer, when properly applied. The lifespan for wood may be extended somewhat by sealing any gaps and using a quality primer, although the shorter lifespan becomes quite apparent when wooden trim is painted alongside a more durable wall material.
Low-gloss paint will cure more quickly. Interestingly, though oil-based paint takes more time to dry, it should be fully cured within 7 days. If you still want more information about paint dry times, consider the answers to these frequently asked questions. Ideally, you should wait until your paint project has fully cured before you hang artwork or otherwise resume regular use of a newly painted surface. The cure time for latex paint can be as long as a month, while the cure time for oil-based paint is about a week.
Yes, patience is key if you want quality results that last. Failing to wait the recommended recoat time can weaken the bond between the paint and the surface, leading paint to possibly blister, crack, or peel down the line. That 4-hour period is the recommended wait time between coats of latex paint, but for an oil-based product, wait 24 hours between coats. The recommended dry time between coats of latex paint is 4 hours.
For oil-based paint, wait 24 hours between coats. Maintaining the ideal temperature and humidity level in the environment, and keeping the space well ventilated, will keep dry times to the shorter end of the range. But trying to hasten paint dry times is a bad idea; this can weaken the bond between the paint and the surface and lead to peeling or cracking down the line. As paint dries, it releases gases and odors.
This is one reason why water-based paint, which typically has less harmful VOCs volatile organic compounds than oil-based products, is preferred for interiors, especially bedrooms. If using a water-based, low-VOC paint, you should still wait at least 4 hours before sleeping in the room. With oil-based paint, wait at least 24 hours before bedding down in a freshly painted room.
Patience is a virtue—particularly when it comes to paint projects! Stick to the recommended wait times between coats, and the suggested cure times before resuming daily use, and your painted surfaces will look great and really last.

Always consider the weather when painting. The drying time for a primer depends on many factors. Different types of primers dry at different rates. Different brands and types of latex paint can also have varying drying times. The key is to always read the package instructions for more information. How dry or sealed the surface is that you are painting also impacts the time it takes to dry. A dry or porous surface will absorb primer more quickly, which could speed up drying time.
Weather conditions could play a role in the drying time. When painting outdoors, hot dry weather, cool temps and high humidity will all affect how quickly your paint dries. Primer and paint dries faster in hotter dry weather while colder temperatures or high humidity areas can make drying process slower.
Another factor is the wind, which can speed up the drying process. One hour after the primer is dry to the touch, light rain should not be able to penetrate the primer. The primer of an exterior paint job needs to be dry before a heavy rain or it may wash off.
