Is Spray Paint Waterproof: All You Need to Know about Waterproof Paints

If you are fond of renovating old pieces of junk or furniture, you would know the importance of spray paints. Spray paints are massively popular for their quick drying time, consistent results, lasting finish, and easy application, not to mention, they can stick to any sort of surface out there, with bright and vibrant pigment. I have always preferred them, considering that they have different types of formulas with a variety of finishes and viscosities.

Now addressing commonly asked questions; is spray paint waterproof? Do you need a sealant and primer or spray paints? How can you make the spray paints last longer? How to choose the right type of spray paint for your desired surface.

To save you from the struggle, I have brought together this comprehensive guide on spray guides, their formulas, types, usage, application, and removal. So, don’t waste more time, and let’s get in.

Is Spray Paint Waterproof? – Detailed Answer

Is Spray Paint Waterproof

Well, the answer to this question is not so simple. So, the simplest explanation would be that spray paints are the fastest to dry out there, and some of them are waterproof.

Most of the paints specifically designed for outdoors will be waterproof, given that they will be exposed to rain and sun for the most part. If you are most likely to use these paints for surfaces that have moisture, you need to make sure that they are waterproof and have the ability to withstand moisture.

How to Tell if the Spray Paint is Waterproof? What Makes These Paints Waterproof?

Well, you must be wondering what makes these paints resistant to water. Well, the simplest answer to this question would be that the quality of the things and sealers used in the composition make them waterproof in character.

However, it is equally worth mentioning that some formulas would be more resistant to water than others, considering the sealers and ingredients included in the paint. For instance, water-based tempera paints are great to be used on different surfaces, with minimal damage.

Similarly, acrylic paints are also waterproof, considering that they have the ability to expand and contract when there is a need. Here, latex paints are known for their rubber-like coating which makes them withstand moisture for the longest time, without any peeling or scraping.

Last but not least, if your desired formula is not waterproof, I would advise you to add a sealer that has a clear coat and even a single coat can protect the surface from moisture.

Does Spray Paint Come Off in Water?

Well, if the paint is still wet, it will come off in water eventually, specifically with water-based paints. To prevent this, you can go for spray paints that either have hard rubber-binding sealers or you can always add sealers in the formula yourself. This will help harden the paint without impacting its stickiness, making them long-lasting even in harsh weather. If you are going to be using oil-based compositions, you need not worry as they are naturally great at binding, so even if they are a little bit wet, you are good to go.

Now, what to do if the paint is stuck to your skin? Well, first of all, it is extremely damaging to your health and you should always wear protective clothing that prevents any sort of interaction. Now, if you didn’t know this and it’s done, the only possible solution is that you use oil-based cleaners or soaps with scrubbing agents. However, be gentle while you have toxic formulas on your skin.

Different Types of Spray Paints

Here are some commonly used types of spray paints you can find out there;

Different Types of Spray Paints

Tempera Paints

Tempera Paints are hugely popular for their pigmented formula. These are largely inspired by water paints and have a matte finish after drying. They can be used on different surfaces however, the application is really flat.

The downside to these paints is that they do not resist moisture, so any area that is wet will not be able to carry the pigment well, including your hair and clothes. After one wash, the color will be negligible. Most people use these paints for arts and crafts, as they are quite easy to work with.

Enamel Paints

Secondly, Enamel Paints are another easy-to-use spray paints that are not waterproof. Although these paints are pigments, their results on moisture surfaces are not the best. The quality of the paint is really good, so you will have to pay extra money for the formula. When it comes to the finish, they have a more shiny and glossy look that is great for art and craft projects.

Latex Paints

Similarly, Latex Paints are water-based formulas that are easy to apply as well as dry. These are preferably used by people outdoors, given that they do not get damaged by exposed UV and rain. When it comes to application, you can use brushes as well as rollers which is quite convenient.

They are also eco-friendly and do not include toxins in their formula. However, the downside to this composition is that they are not suitable for smooth surfaces like metals or even plastic.

Oil Based Enamel Paints

In addition, Oil-Based Enamel Paints are designed for long-lasting applications. These are absolutely the most convenient option you can find out there, given that they are easy to use and dry out quickly.

However, I would not advise you to use these paints on porous surfaces. This is because they will have extreme moisture that will peel off after exposing to the surface. Overall, these compositions are not completely waterproof.

Metallic Paints

Last but not least, Metallic Paints, as the name suggests, are known for their shiny and reflective pigment that looks absolutely elegant. These compositions are eco-friendly and include absolutely no toxins, so you can use them in enclosed areas easily. This can be the reason why they are really expensive.

Similarly, even after exposing them to sun and moisture, the results will be unhinged, so you can use them outdoors, without any peeling or flaking. However, using these paints can be a bit tricky.

Now that you know about the main types of spray paints, I hope you can choose the suitable formula and color for your desired project. Just make sure you have done practice before using the right tools to cover any surface.

Is a Spray Paint Toxic?

Well, the bad news about the majority of spray paint formulas is that they can be somewhat toxic. This is because they have VOCs, also known as Volatile Organic Compounds, including toluene, acetone, xylene, or even ethyl ketone, all of which can be damaging to the environment as well as the health of people. Irrespective of the type of spray paint, these elements could be present in any composition.

Now, addressing the important part, does it matter? Yes, it absolutely does. This is because it is common sense that toxins present in the formula can damage your health when inhaled or ingested, even when absorbed into the skin. The damage, overall, depends on the paint you are using as well as the intensity of these toxins used in the paint composition.

However, the good thing is that you can always prevent this damage by adopting some precautions. Here, I would advise you to always make sure you have proper ventilation in the room, not to mention, use protective gear so that the paints do not touch your skin. You can also find modern alternatives, as they are using fewer VOCs and are UV-resistant, making them safe.

Why Should You Use Spray Paints?

Now, you must be wondering what makes these spray paints really special. Well, there is a range of benefits to using these compositions, considering that some of them are resistant to moisture and sun. Here are some of the reasons why I have been using these spray paints for the longest time;

Why Should You Use Spray Paints
  • First of all, these paints are known for their ability to last for the longest time, which makes them suitable for permanent jobs.
  • The fact that they can stick to any surface out there makes them of great value.
  • Similarly, these pants are great for metallic, wood, and plastic surfaces, as they dry out quickly. So, there is no need for you to wait for the drying time, before reusing the tools again.
  • The majority of these compositions are waterproof, so even after exposing them to the rain, the paint will not wash away. You can easily use these paints indoors as well as outdoors.
  • These paints work great as a foundation for your projects, as they are suitable for sticking onto different surfaces, in comparison to other popular options. They also can work best with uneven and rough areas.
  • If you are renovating different furniture pieces and need something easy to use and quick to dry, these spray paints are absolutely incredible.
  • You can further use them to coat old items, if you have the intention to sell them, such as bicycles or any other piece.
  • In addition, they are incredible at lasting long, given that they have a lasting finish despite having a fast-drying character.
  • The result of these paints is absolutely vibrant and bright, so you can easily add life to the piece.
  • However, it is absolutely significant that you have a clear idea of what to use where, and how.

How Long Does Spray Paint Take to Dry?

Another question many people asked about spray paints is their drying time. Well, the good thing about these formulas is that they are incredibly long-lasting and durable, despite having a fast-drying character. On average, you just need to wait at most 24 hours after the application process. This is more than enough time to fully cure the paint, even if the object has a certain amount of moisture. Hence, waiting for this much will make sure the paint sticks to the surface incredibly and doesn’t peel off easily.

Similarly, although for the entire curing process, you have to wait for some hours, it can be ready to touch in just thirty minutes which is nothing in comparison to other alternatives out there. Here, I would say applying it thin and consistently further makes the drying process easy and fast. You can always use a dehumidifier or a fan to make sure the paint dries efficiently. Just make sure the room where you are painting has a temperature between 65 and 85 degrees Fahrenheit.

How to Apply Waterproof Spray Paint: A Step-by-Step Guide

Applying the spray paint is not challenging and all you need to know is the suitable type of paint you will be using as well as the equipment, and practice. To save your day, I have brought together this step-by-step guide along with some queries that can help you with a smooth process. So, dive right in for more.

What is the Preparation Phase for Using the Waterproof Spray Paints?

First of all, I would say preparation is the key, as already explained in the above-mentioned answers. These paints can be waterproof or not, depending on the materials and sealers used in the composition.

So, if you are most likely dealing with heavy sealers and toxins, it is absolutely important that you spend some time preparing yourself as well as the surface, so that it can withstand the paint, without peeling or flaking off. To start with, you need to clean the object with rubbing alcohol or a thinner.

So, starting off, if you are using any type of wood or material that requires sanding, it is ideal that you get sandpaper. This step is important to make sure the surface is smooth before you paint the surface.

If you, for whatever reason, skip the preparation step, it would not only allow water to penetrate into it but also the paint will bubble and all you will be left with are flakes and scratches. So, in order to make the finish long-lasting and durable, it is absolutely important that you prep and prep before painting.

Does Application Matter for Waterproof Spray Painting?

Now the second step is the application phase. As the name suggests, it makes up the most important step in the entire process. Yet, it requires time and skill, needless to say, some common sense. You are not to rush into the process at all. Before that, it is ideal that you do some calculations in your mind, such as the time you will be giving it to dry, the coats you will be needing, and some equipment you will use for the application step.

Here, I would say make sure to at least go for two to three coats. This is because not coating the surface properly will provide you with inconsistent and rough strokes that don’t look appealing, needless to say, cover it properly. Accompanied by this, it is equally significant that the application is provided with adequate drying time. Now, it depends on the number of coats you have used. For instance, for three coats, you need at least 24 hours for drying to make sure the moisture does not penetrate through the paint.

Always Finish it Off

Last but not least, now that you are done with the application, you need to finish it off. This entire step will not take you more than three minutes and it can do wonders for your paint. This is specifically the part where you correct all the mistakes.

For instance, if the water-based paint has some pops on your wood, you can also go back to highlight it from some places. You can also see whether there are some spaces left and use fresh paint to fill them.

Does Spray Paint Need to be Sealed?

Yes, sealing the spray paint can always help you with a lasting finish. This is because these alternatives create a clear topcoat that makes sure the paint doesn’t peel off or become flaky. So, adding one coat of sealers can add an extra layer of waterproofing or durability.

However, you should always add it once the paint is completely dry, which on average demands waiting for 24 hours. Similarly, if your paint formula already has sealants, there is absolutely no need to add a sealant for this application.

Do You Need a Primer for Spray Paint?

Well, it all comes down to the individual project requirements as you would not need a primer for all types of spray paints or all the projects. For instance, if you are most likely to be using spray paints for outdoor wood furniture, it always makes sense that you use primer as they allow the paint to stick well to the surface you are working with.

Similarly, if you are never fully satisfied with a spray paint application, adding a single coat of primer can make the finish even more lasting, preventing scraping and peeling.

Can You Spray Paint in the Rain?

Well, the answer to this question is no. At this point, it is common sense that rainwater can easily wash it away, irrespective of it being waterproof, as it hasn’t gotten a chance to even bond, let alone dry. Hence, it is always wise that you wait for some time and apply it on a sunny day.

However, if there is some emergency and you need to do it as soon as possible, it is time that you paint the object in the garage. Just make sure the temperature is regulated and the situation is not humid so that the paint doesn’t peel off easily.
