What Happens If It Rains On Fresh Paint? A Detailed Look
It can be frustrating when you’ve just painted something, only to have the sky open up and rain pour down unexpectedly. If you’ve been wondering what happens if it rains on fresh paint, you’ve come to the right place.
If you’re short on time, here’s a quick answer to your question: Rain can ruin fresh paint by causing blistering, cracking, glossy spotting, discoloration and adhesion issues. The severity depends on the type of paint, if primer was used, humidity levels and how hard it rains.
In this detailed guide, we’ll cover everything you need to know about how rain impacts freshly painted surfaces. We’ll look at how different paints fare in the rain, steps you can take to protect fresh paint, and what to do if your paint does get rained on before fully curing.
How Soon Can You Get Rain on Fresh Paint?
When it comes to painting, timing is everything. One of the biggest concerns for homeowners and professionals alike is what happens if it rains on fresh paint. Will all your hard work go down the drain?
Let’s take a detailed look at the factors that can affect the drying and curing process of paint when rain is in the forecast.
Most paints take 24-48 hours to fully cure
While most paints may feel dry to the touch within a few hours, they actually take much longer to fully cure. In general, it takes about 24-48 hours for paint to completely dry and harden. During this time, the paint is vulnerable to damage, including rain.
If rain falls on fresh paint before it has fully cured, it can cause the paint to run or streak, leaving an uneven finish. Therefore, it is important to protect your freshly painted surfaces from rain and moisture during this crucial curing period.
Humidity affects curing times
Another factor to consider is the level of humidity in the air. High humidity can prolong the drying and curing time of paint. When there is more moisture in the air, it takes longer for the water in the paint to evaporate. This can extend the curing time by several hours or even days.
To ensure proper curing, it is best to paint in low humidity conditions and avoid rainy or humid days whenever possible.
Darker colors take longer to cure
Did you know that the color of the paint can also affect the drying and curing time? Darker colors, such as deep blues or blacks, tend to take longer to dry and cure compared to lighter shades. This is because darker pigments absorb more heat from the sun, which can slow down the evaporation process.
So, if you have just painted a room with a dark color, it is even more important to protect it from rain or moisture for an extended period of time.
What Kind of Damage Can Rain Cause on Fresh Paint?
While rain can be a welcome relief on a hot summer day, it can pose a significant threat to freshly painted surfaces. The moisture from rain can cause various types of damage to fresh paint, including blistering, cracking/peeling, glossy spotting, discoloration, and adhesion problems.
Let’s take a detailed look at each of these potential issues:
Blistering
One of the most common problems caused by rain on fresh paint is blistering. When rainwater penetrates the paint film before it has had a chance to dry completely, it can create bubbles or blisters on the surface.
These blisters can range in size from small, barely noticeable bumps to larger, more pronounced formations. Not only do they affect the appearance of the painted surface, but they can also compromise the integrity of the paint job.
Cracking/Peeling
Rain can also lead to cracking or peeling of fresh paint. When rainwater seeps into the paint film, it can cause the paint to expand and contract, leading to the formation of cracks or peeling of the paint layers. This issue is especially common in areas with frequent rain or high humidity levels.
The cracks and peeling not only detract from the aesthetics of the painted surface but can also expose it to further damage and deterioration.
Glossy Spotting
Another problem that can occur when rain falls on fresh paint is glossy spotting. This happens when rainwater disrupts the drying process of the paint, leaving behind glossy or shiny spots on the surface.
These spots can be particularly noticeable on surfaces with matte or satin finishes, as they create an uneven appearance. Properly drying the paint after rain exposure can help minimize this issue.
Discoloration
Rainwater can also cause discoloration of fresh paint. When rainwater mixes with wet paint, it can result in the pigments spreading or bleeding, leading to inconsistent coloration. This can be especially problematic when painting large surfaces or using multiple coats of paint.
The discoloration can be quite noticeable and may require touch-ups or repainting to achieve a uniform color.
Adhesion Problems
Lastly, rain can interfere with the adhesion of fresh paint to the surface. When rainwater comes into contact with wet paint, it can wash away some of the paint particles, affecting the bonding between the paint and the substrate.
This can result in poor adhesion, causing the paint to easily chip, flake, or peel off. Proper surface preparation and allowing the paint to dry thoroughly can help mitigate this problem.
To prevent these issues, it is essential to monitor weather conditions when planning a painting project. If rain is expected, it is best to postpone painting until the weather clears up. Additionally, using high-quality paint and following proper application techniques can help minimize the potential damage caused by rain on fresh paint.

How Different Paint Types Hold Up to Rain
When it comes to rain and its effect on fresh paint, different paint types can behave differently. Understanding how each type reacts to moisture is crucial in determining how well your paint job will hold up over time.
In this section, we will explore three common paint types and their resilience to rain: latex paint, oil-based paint, and other specialty paints.
Latex Paint
Latex paint, also known as water-based paint, is one of the most popular choices for interior and exterior surfaces. It is known for its quick drying time, low odor, and ease of use. When it comes to rain, latex paint has a high level of water resistance.
It can withstand light rain showers shortly after application without significant damage. However, heavy rain or prolonged exposure to moisture can cause the paint to become soft and eventually peel or bubble.
To ensure the longevity of your latex paint job, it is important to allow it to fully cure and dry before exposing it to rainy conditions.
Oil-based Paint
Oil-based paint, also referred to as alkyd paint, is known for its durability and glossy finish. Unlike latex paint, oil-based paint is less water-resistant and can be more susceptible to rain damage. When exposed to rain shortly after application, oil-based paint may take longer to dry and cure compared to latex paint.
If the paint has not fully dried before it gets wet, it can result in streaks, runs, or an uneven finish. To protect an oil-based paint job from rain, it is recommended to avoid painting during rainy seasons or to use a protective covering if rain is expected.
Other Specialty Paints
There are various specialty paints available on the market, each designed to meet specific needs and provide unique properties. These paints can include epoxy paint for floors, waterproof paint for bathrooms, or heat-resistant paint for appliances.
The water resistance of these specialty paints can vary depending on their intended purpose. It is best to consult the manufacturer’s recommendations or seek professional advice to determine how well these paints will hold up to rain.
It is worth noting that regardless of the paint type, the quality of the paint and its application can also play a significant role in its resistance to rain. High-quality paints and proper surface preparation can enhance the paint’s ability to withstand moisture.
Additionally, applying multiple coats of paint and using a primer can provide an extra layer of protection against rain damage.

Steps to Help Protect Fresh Paint from Rain
When it comes to painting, rain can be a real downpour on your plans. However, there are steps you can take to protect fresh paint from the unexpected showers. By following these tips, you can ensure that your paint job remains intact and looks great for years to come.
1. Check the weather forecast
Before you start painting, it’s important to check the weather forecast. Look for a stretch of dry weather with no rain in the forecast for at least 24 hours. This will give your paint enough time to dry and cure properly.
Websites like weather.com or accuweather.com can provide you with accurate and up-to-date information on the weather conditions in your area.
2. Use primer
Using a primer before applying the paint can provide an extra layer of protection against moisture. Primers are designed to create a smooth and uniform surface for the paint to adhere to, helping to prevent water from seeping into the painted surface.
Make sure to choose a primer that is specifically formulated for the type of surface you are painting, whether it’s wood, metal, or drywall.
3. Opt for quick-drying paints
When selecting paint for an outdoor project, consider choosing a quick-drying formula. These paints are designed to dry faster, which can help minimize the risk of rain ruining your freshly painted surface. Look for paints labeled as “quick-drying” or “fast-drying” for the best results.
4. Pick the right sheen
The sheen of the paint can also play a role in its ability to withstand rain. Glossier finishes, such as semi-gloss or high-gloss, tend to be more water-resistant than flat or matte finishes. Consider using a paint with a higher sheen for areas that are more exposed to the elements, such as exterior walls or trim.
5. Maintain proper temperatures
Temperature can affect the drying time of paint, so it’s important to paint in the right conditions. Most paint manufacturers recommend applying paint when the temperature is between 50°F and 90°F (10°C and 32°C).
Painting in temperatures outside of this range can result in longer drying times or even paint failure. Keep an eye on the temperature and avoid painting if it’s too hot, too cold, or if rain is imminent.
6. Use tarps for outdoor projects
If you’re painting outdoors, using tarps or drop cloths can provide an added layer of protection against rain. Cover any surfaces that you don’t want to get wet, such as decks, furniture, or plants, to prevent water damage.
Secure the tarps tightly to ensure they don’t blow away in the wind, and remove them once the paint has dried completely.
By following these steps, you can minimize the risk of rain damaging your fresh paint job. Remember, prevention is key when it comes to protecting your paint from the elements. So, take the necessary precautions and enjoy a beautiful and long-lasting paint finish.
What to Do if Fresh Paint Gets Rained On
Painting a room or an exterior surface can be a time-consuming process that requires careful preparation and execution. Unfortunately, even with all the precautions taken, sometimes unexpected weather conditions, such as rain, can pose a threat to the freshly painted surface.
If you find yourself in this situation, here are some steps you can take to minimize the damage and restore the paint’s appearance.
Allow paint to fully dry if damage is minimal
If the rain exposure was brief and the damage to the paint is minimal, it is essential to allow the paint to fully dry before taking any action. Painting in wet conditions can lead to further issues, such as streaking or peeling.
Therefore, it is crucial to give the paint enough time to dry completely before attempting any repairs.
Sand down any damaged areas
If the rain has caused damage to the paint, such as creating water spots or causing the paint to blister, it is necessary to address those areas. Start by gently sanding down the damaged spots using fine-grit sandpaper.
This will help smooth out the surface and remove any imperfections caused by the rain. Be cautious not to sand too aggressively, as it can damage the underlying layers of paint.
Spot paint damaged sections
Once the damaged areas have been sanded down, it’s time to spot paint those sections. Use the same type and color of paint that was originally applied. Apply a thin layer of paint using a brush or a roller, making sure to blend it seamlessly with the surrounding painted areas.
Allow the spot-painted sections to dry completely before evaluating the results.
Completely repaint if damage is severe
If the rain has caused extensive damage, such as significant peeling or discoloration, spot-painting may not be sufficient. In such cases, it is best to consider completely repainting the affected surface. Properly prepare the surface by cleaning it and removing any loose or damaged paint.
Apply a primer if necessary, and then proceed with the new coat of paint. This will ensure a uniform and fresh look, restoring the surface to its original condition.
Remember, prevention is always better than cure. If you know there is a chance of rain, it’s best to avoid painting altogether or choose a different time when the weather is more favorable. However, if you find yourself facing unexpected rain during a painting project, following these steps will help you mitigate the damage and restore the paint’s appearance effectively.
Conclusion
Getting caught in the rain can wreak havoc on freshly painted surfaces. Certain steps can be taken to minimize rain damage like using primer, choosing the right paint sheen, and covering outdoor projects.
If your paint does get rained on, assess the damage and make spot repairs or repaint as needed once fully dry. With the information in this guide, you can help protect your painted projects from unpredictable weather and handle any rainy day mishaps.
