Affordable, versatile, lightweight, and easily portable Spray paint is the ideal choice for everyone to decorate nowadays. However, due to its distinct application method, there are some aspects to consider before starting.
Spray paint is suitable to decorate your home, car or even furniture. It's half the effort and has twice the effectiveness compared to the traditional method of using a brush to paint.
One of the main concerns when spray painting is to know how long does spray paint take to dry? It's essential to allow the paint to dry before applying another coat thoroughly.
But most people do not like to wait and within just 10 or 15 minutes after coating the first layer of paint they started to coat the second layer, which may result in bubbling of spray paint.
It is essential to know how long it takes for paint to cure, specifically for recoating. Failure to do so could end up ruining your entire project.
How Long Does Spray Paint Take to Dry?
This is the most commonly asked question. Most of the Spray paint take 10 to 30 minutes to dry to the surface and take upto 24 hours to dry completely. The drying time depends on the type of material you're putting it to and, also depends on the number of colours, coats, etc.
If you wish to apply multiple coats, it is necessary to wait for the first coat to dry before applying the second.
Also, allow the spray paint to dry when using more than one colour to prevent streaks.
The Four Stages of Drying
It is essential to understand the distinction between dry and wet paint. It is not a simple black-and-white scenario.
After the application process is completed, the paint goes through four phases before becoming fully dry and ready to use.
Types of Spray Paint Being Used
Many different types of spray paints can be readily available on the market. But you should always go for the best spray paint. Each spray paint comes with a unique design that significantly impacts how long the drying process can take.
The points discussed below also affect the drying time. So, if you want to understand the kind of paint to use, read below points.
Enamel Spray Paint
This spray paint will dry in just a few minutes. The main reason behind this fast drying process is the rate of evaporation of the solvent. The presence of oxygen in this formula links the polymers, resulting in creating a hard surface.
After the application of paint is completed, it can take between 10 to 30 minutes to dry surfaces, and it typically takes about 8 hours to get the complete drying.
Lacquer Spray Paint
This is another great available option. Utilizing lacquer spray paint will allow for a quicker drying time. For certain types of latex paint, you could achieve the same result when water is used to make the paint less diluted.
Lacquer Paint is produced with thermoplastic polymers. The process of drying the surface takes just three to five minutes. The average time for a hard dry is around three hours.
Epoxy or Polyurethane Spray Paint
The paint Epoxy, also known as Polyurethane, I would say is the most fast-drying spray paint available. With this formulation, you must wait until the two components undergo the chemical reaction.
Within five minutes, you'll be able to see an area drying. Drying usually takes approximately an hour.
If you want some more details you can read my detailed article on types of spray paints.
There are various environmental factors that may affect the drying time of spray paint like extreme hot or cold weather conditions but among various environmental factors humidity is the most important one.
Humidity is an essential factor that can hurt the general drying process. When it comes to painting, it is recommended to choose an area with low humidity.
In the case of temperatures, hot weather can accelerate the drying of the paint.
Drying Time-Based on Material
Different materials might have a higher permeability or are more prone to be damaged by paint, and you'll need to be aware of this.
The time required to dry a new coat of paint will totally depend on the material you're using to paint.
The most commonly used ones, which I'll discuss more are metal, cardboard glass, plastic and rubber.
How long does spray paint take to dry on cardboard?
Cardboard has a soft surface which makes it susceptible to accidental damage, and you could end up ruining it if you aren't sure of the right thing to do.
But, it is one of the most rapid drying items. If you're painting it in a ventilated area, It shouldn't take longer than fifteen minutes to allow the coat to dry.
How long does spray paint take to dry on metal?
Spray paint is typically used to repair a range of metal objects like doorknobs, refrigerators and cars. If you're in an arid space with no humidity, the paint will dry in less than 10 minutes.
How long does spray paint take to dry on glass?
The process of painting on glass can be challenging, and not allowing the paint time to dry may result in drip marks.
Try applying each layer as gently as possible and take at least 15 minutes before applying the next coat. It usually takes at least 24 hours to allow the paint to completely dry.
How long does spray paint take to dry on plastic?
Plastic is among the most simple substances to paint on. It can dry in an average of around 30 minutes.
However, you can be sure that the paint coats will not be at the fully dry stage until they've been allowed to remain for at least 3 hours.
How long does spray paint take to dry on rubber?
Since rubber is porous, it is recommended to be patient for at least 30 minutes before applying another coat.
Keep in mind that it is unlikely to reach the point of complete drying within under 24 hours. If you plan to paint an object from rubber, you must think ahead.
How To Make Spray Paint Dry Faster
There are numerous ways that you can help spray paint dry more quickly. The most straightforward method is changing the elements in your environment, including humidity, air circulation or temperature.
But, the way it is applied could be a significant factor in the drying time. Here are seven suggestions to speed up the drying speed of spray paints.
1. Use Thin Coats
In applying the paint, your most effective guideline to follow is to apply paint in short coats. The less paint you use, the faster the drying time.
The method you employ for applying spray paint is likely to produce thin coats. But, you could make mistakes that can result in the paint drying more slowly. For instance, applying oversized coats of paint can cause tacky paint.
Use your whole hands to push the container across the surface while applying the paint to get the most effective results. Do not just move your wrist.
This can assist you in avoiding the overlap of too many paint layers in one go and stick to thinner coats instead.
It is also possible to use the solvent or paint thinners to change the thickness. Spray paint that is fast drying also tends to allow greater control over the application.
2. Lower the Humidity
For spray paint to dry quickly, you require low levels of humidity. The high humidity can slow down drying time and can cause damage to your painting, like drips of paint and dust contamination. A humidity level between 40 and 70% is considered ideal.
Never paint during particularly humid days. If your area is moist, you can try to reduce the moisture content of the air by using the aid of a dehumidifier.
Sometimes, opening the windows and doors when painting can be beneficial in the case of a home that is humid. If the outside is damp, make sure to close the windows.
3. Create Air Circulation
Ventilation is essential when working with paints, especially spray paint. A variety of paints, including most spray paint brands, have volatile organic compounds (VOCs), which can be harmful to breathe.
Before painting, it is essential to open the windows and ensure that there is ample airflow.
If you're working in a room, you can use a fan to create airflow. Make sure the fan is running when you've finished painting to extend the drying time.
When you're working outdoors, painting in the garage gives you access to the box fan too. Avoid spray painting in windy weather outside to ensure safety.
Be aware not to use the fan in a dirty area. This can cause the fan to blow up debris and dirt and cause it to adhere to the paint. Do not place it too close to it because it can cause your paint to shift and spread.
4. Run a Heater Nearby
As a box fan, the space heater is the ideal way to generate more airflow. The combination of increased temperatures and air circulation is advantageous if you want to shorten drying time by a few hours.
A heater can be particularly beneficial during humid or cold days. A heater will also lower the humidity levels.
There are many methods to utilize this technique. It is possible to run the heater in your work area to aid in helping paint dry more quickly.
Allow the painting to dry with a heater near the surface. Then, the paint could dry to touch within minutes rather than hours. Alternately, you can raise the temperature of your house if you're painting inside.
Heating the paint does not dramatically reduce dry time. However, it can cut down the time for the paint to dry, from 24-hours to just a few hours. If you do not have a space heater or a hairdryer, you could try running an air-dryer across the surface you've painted.
5. Paint Outside on a Sunny Day
Why not let Mother Nature assist in drying your paint faster? You can regulate the climate without worrying about the temperature, humidity, or airflow by selecting a pleasantly warm day to paint outside. The safest choice is to paint with outdoor spray paint on a hot day.
Make sure you can paint outdoors during a sunny and warm day. Many artists enjoy painting outside in summer, as the warmer temperatures accelerate dry time.
Paint immediately early in the morning, so your artwork has plenty of the time needed to dry thoroughly.
Paint on a day in the range of 65-85 degrees F. The humidity should be average, and there is no rain predicted.
6. Coat Spray Paint and Furniture Polish
A new trick that can help spray paint dry quicker is applying wax-based furniture polish. It can be challenging to locate but can help spray paint dry in a flash.
It functions as an adhesive sealant that is matte. Find a polish based on wax that spreads that you can stream for easy application.
Spray paint the surface like you usually, and then coat the paint with polish for furniture. Place the can just a few inches above the object and paint the entire surface.
You might need several thin coats. Let it dry for about 5 minutes before applying another coat. Clean the polish using a soft rag. Be careful not to apply excessive pressure, or the polish could be sucked off.
You may only require less than a single coat of polish for specific projects. For instance, wood is likely to require at least three levels of furniture polish.
Always verify that the object is dry by using the pads of your finger, which you gently rub. If the surface is dry, you can handle the thing.
7. Curing Spray Paint in Oven
The final step is to cure spray paint using the oven of a toaster. Once the paint is on a dry surface you can bake the paint at 250 degrees F for approximately two hours.
Baked enamel is a great alternative. Certain paints could be cracked or bubble up in high temperatures. Make sure you use paint that's safe for curing in the oven.
Don't use over-to-dry spray paint. After the spray paint has dried. It emits harmful VOCs and other chemicals into the air, which could be absorbed by the inside that of the oven.
When cooking food using the oven, these chemicals will be released into the foods. Take care when using this method. Make use of a toaster oven only to dry paint.
What Are Some Of The Fastest Drying Spray Paints?
Spray paint is generally quick drying. Because of this, I'd recommend the quality of the paint over the drying time, in this case. Krylon, Rustoleum, and Hammerite are all top quality spray paints.
Krylon is also renowned for its easy spraying process and fast drying.
However, Rustoleum is possibly the most well-known brand of spray paints available in the present.
Time to dry Rustoleum Spray Paint
Various levels of dry and distinct formulations of Rustoleum states that it can dry tack-free in between 2 and 4 hours.
It can easily be cleaned without leaving marks or damage within 5 and 9 hours, and it is hard dried within 24 hours.
Crayola Spray Paint drying times
It's an exciting idea because Crayola and oil-based, non-permanent paint is intended for children to paint the sidewalk or driveway.
It can be cleaned off using water. It is usually dry to touch in approximately 30 minutes.
The Hammerite spray Paint drying time
Hammerite claims to dry tack in just 2 hours, handle dry in four hours, and completely dry in just 24 hours.
Be aware of the impact of humidity and temperature is an essential role in the drying time of all paint brands. The kind of material you're painting can play a huge role, as does reading the instruction, apply paint with light coats and be cautious to avoid many dollars and headaches, as well as rework.
