Proguard F99811 Liquid Rubber EPDM

rv roof coating recommendationsThis liquid rubber EPDM comes from the same Proguard brand as the above product. It’s a durable material that delivers the same high quality results.

This is a liquid EPDM that requires a catalyst for its application. The catalyst comes included with the coating and you need to mix them well together before you apply it to the roof. Depending on your RV’s roof material, you might also need to use a primer. For example, a TPO roof would require a primer, but a rubber roof doesn’t need it.

You have to clean and dry your roof before applying the coating. This would ensure proper adhesion to the roof and proper protection and sealing. The one gallon can is enough to create one coat over a 42 to 64 square feet roof. This would create a 20 mil thick membrane, which is thick enough, so you don’t need to add extra layers.

RV Roof Coating Buying Guide

There are plenty of reasons to invest in RV roof coating. Your RV is an expensive investment and replacing its parts is usually not a cheap process, the roof included. That’s why it’s important to protect this part, which would ensure that it would be able to stay in good condition for longer without needing repairs.

However, to make sure that you get proper protection for your roof, you should choose not just any but the best RV roof coating. The quality of different roof coating products and the level of protection that they can provide for your roof depends on several factors. That’s exactly what this section will explore.

By taking into account each of these factors, you’ll be able to choose the right roof coating for your recreational vehicle. It will also make your shopping experience less stressful since you’ll know exactly what to look for.

Types of RV Roof Coating

The first thing to consider is the type of RV roof coating that you’d prefer. There are a few available options and each has its advantages and downsides.

  1. Acrylic. One of the most common options is acrylic coatings. It’s a good choice for those that are looking for a cheaper solution. Acrylic coatings are fairly durable. They can also reflect damaging sunlight and prevent water damage and leaks. One of the downsides of this type of RV roof coating is that it’s usually thinner, which means that you need to apply several coats in order to get the best results. This means higher cost and more time spent applying it. Another downside is that it’s not as long lasting as the other two types. And it doesn’t handle very well pooling water.
  2. Silicone. This type of roof coating is a bit more expensive but it offers the strongest protection, so the benefits outweigh the costs. It applies without any primer and it creates a thick layer. In some situations, you won’t even need to do a second layer. The silicone coating is also very effective at protecting the roof from different outdoor elements and weather degradation. It reflects the UV rays and creates a perfect seal. The material is also flexible, which means that it moves with the roof and doesn’t crack or brittle. Moreover, the ponding water doesn’t do any harm to it. The only downside of this material is that it tends to get dirty fairly quickly. However, if you regularly wash your RV, it shouldn’t be an issue.
  3. Urethane. This is also one of the more durable options and is also a popular choice among many RV owners. Pricewise, it’s somewhere in between acrylics and silicon coatings. It provides good impact resistance, protecting the roof from falling branches and other debris. The coating also resists ponding water and it is UV reflective. The downside, though, is the strong odor that it emits during application.
  4. EPDM rubber. This is also a common type of roof coating used on RVs and they offer a few benefits that set it apart from the rest. One of the defining features of this material is its resistance to UV and ozone. EPDM has also great resistance to heat aging and weathering. It can survive in both very high and low temperatures, making it an all season coating. Since it’s also resistant to water swelling, ponding water is usually not an issue.
  5. Aluminum. This type of coating is not widely used in RV applications since they add quite a bit of weight.

Most of these types of RV roof coatings are sold in liquid form. It makes it easy to apply them. All you need is a paint brush and you apply it as if you’re painting the roof.

Your RV’s Roof Material

Another important consideration is your RV’s roof material. It’s important to choose the coating that would be right for the material of your roof. Otherwise, it might not adhere correctly or it will not be able to provide the necessary protection for the roof.

Most RV roofs are made of either metal, rubber (EPDM or TPO), or fiberglass. So, start by checking the roof material that you have. Many coatings are formulated for application on certain materials and it’s better to use them for that specified application for best results. For example, a rubber formulated coating might not work well on fiberglass roofs and vice versa.

This will make picking the right coating a lot easier. For example, if you have a rubber roof, you should look for products that specify that they are rubber roof coatings. Or if you have a fiberglass roof, look for fiberglass coating.

However, it’s also worth mentioning that some coatings work on a variety of surfaces and they can be applicable on all of these RV roof materials. Check the product’s specifications to understand if it would work for your situation and if it would be able to bond correctly.

UV Resistance

When UV rays hit certain materials, they cause a chemical reaction that results in material degradation. This is exactly what’s happening to your RV’s roof when it’s constantly exposed to the sun.

An effective way to prevent this damage is by applying high quality roof coating. The material reflects the UV rays, so it doesn’t damage the roof.

Moreover, another advantage of UV resistance is that it helps to maintain the heat off the roof. This results in a cooler environment inside the RV and lower energy costs for running the AC.

Water Repellency

Most RV roof coatings offer water repellency. However, some do it better than others. A good product would create a seal, ensuring that no water enters your RV even during heavy rain.

Some manufacturers recommend doing two or more layers in order to create watertight protection for the roof. But it depends on the product since some are thicker than others. For thicker coatings, one layer might be enough while for others, you might need to do two or more.

Impact Resistance

Since your RV will probably be exposed to all kinds of weather and elements, the roof coating should provide protection against them. A good material should also be able to provide protection against wear and tear caused by wind, rain, snow, and different debris.


The coating material should also be flexible. Your RV’s roof can contract and expand with changes in temperature. And the coating should remain flexible, moving with the roof’s changes. This is important for preventing cracking or peeling of the coating.

Ease of Application

Roof coatings can differ in how they are applied and some are more time consuming than others. Look for a coating that can be applied with minimum hassle.

Most RV roof coatings come in a thick liquid form. To spread it over the surface of the roof, all you’ll need is a paint roller, which will provide quicker application and smoother results.

In some cases, you’ll also need to use a catalyst that you mix with the coating. This, of course, adds time to the process of application.

Another thing that determines the ease of application is the number of layers that you’ll need to do. Applying one coat is, of course, faster and easier than applying two or four coats. So, keep this also in mind. In the specifications of the products, you can usually find the recommended number of layers of optimal performance.

Time to Dry and Cure

Different coating formulations will also differ in how long it takes for them to dry and cure. Figuring this out is essential if you will be doing several layers. Since if it doesn’t dry and cure in time, moisture will create bubbles and other weather elements can create additional damage. That’s why it’s important to choose a coating with a dry and curing time that you can fit into your schedule. And usually, the faster it is, the better.

A good drying time would be about 2 to 3 hours. This would allow you to apply several coats in a day, after which you can leave it to cure. As for curing, a good coating would cure in 24 to 48 hours. However, others can take as long as up to 4 days.

It’s worth mentioning that drying and curing time will also depend on the weather and temperature. During warmer summer months, the required time decreases significantly. Cold and damp conditions, on the other hand, extend the drying times.

However, it’s also important to note that many manufacturers don’t recommend applying the coating in intensive heat, so it would be better to work on your roof in the mornings and evenings.


RV roof coatings also come in different colors. The most common color is white since that’s the color of most RVs. Other coatings come in a clear color or tinted color. If your RV roof isn’t white, look for the appropriate color.

If you do buy the white color but then want to tint it, make sure that whatever paint material you’re adding is compatible with the formulation of the coating.


To have the least impact on nature, choose also a roof coating that is environmentally friendly. It should be made of non-toxic material that will have low VOCs. By choosing a non-polluting coating, you will not only be protecting the environment but also your health.


The price is an important factor when choosing any product and it’s also important when choosing an RV roof coating. So, start by outlining a budget, which will help you narrow down the options. This will make finding the perfect product an easier and faster process.

When considering the price of the different RV roof coating products, try to find a balance between cost and quality. Keep in mind that a good roof coating is going to cost you. A good quality product is usually not the cheapest one. However, it doesn’t mean that you have to buy the most expensive one either. There are plenty of affordable options that will also deliver good results.

You can look at the roof coatings that fit into your budget and then look at user reviews to understand the quality that the coatings offer. This will help you choose a good coating without wasting your time looking at products that you can’t afford.

RV Roof Coating Frequently Asked Questions

What is an RV roof coating?

An RV roof coating is a material that is used to seal, weatherproof and waterproof the vehicle’s roof. It is used on most recreational vehicles, including on trailers, motorhomes, 5th wheels, etc. This coating plays a crucial role in protecting your RV’s roof.

The RV roof tends to wear and tear with time due to the effects of weather and different outdoor elements. For example, if you have a rubber roof, it can become chalky. Roof coatings help to prevent this wear and tear. Instead, they revive the condition of the roof, making it look as good as new. And as a result, you don’t need to do costly repairs to your roof as often.

Roof coatings also act as a sealant, which prevents water from penetrating and damaging your recreational vehicle. The coating can also be used around skylights, vents, air conditioner,s and other parts that need leak-proofing.

How does an RV roof coating work?

How roof coating will work depends on the type you choose. For example, if you’re using liquid rubber, such as silicone rubber or EPDM rubber it comes as a self-leveling fluid that creates a waterproofing membrane over your roof.

The coating adheres to the surface of your RV’s roof, creating a strong bond. This means that the roof’s surface is protected from weather and elements.

What are the benefits of RV roof coating?

If you’re still unsure if you should invest in RV roof coating or not, here are a few of its persuading benefits.

  1. Reduction of wear and tear. Your RV’s roof takes all the beating. It has the most exposure to elements, such as rain and snow. It is also the most exposed to the sun, absorbing a lot of the UV light. All this causes it to degrade and lose its original look. A roof coating creates a barrier that protects the surface of the roof from all this wear and tear. And as a result, it extends the life of the roof.
  2. UV reflective. The material used in combination with the white color offers an effective reflection of the UV light. Due to this, the roof stays protected from the damaging rays.
  3. Temperature regulation. This advantage is closely related to the previous one. Since the coating reflects most of the UV rays, it helps to keep the roof at a cooler temperature. This also helps to regulate the temperature inside your RV and maintain it at a more comfortable level. As a bonus, you’ll also be using less power since you won’t have to run your air conditioner as often.
  4. Leak prevention. One of the main reasons to invest in RV roof coating is also to prevent leaks and provide structural protection for your RV. The coating seals your roof and any cracks that could potentially become sources of leaks. By creating this watertight membrane over your roof and keeping away the moisture, it will also help prevent rust, corrosion, and mildew.
  5. Flexible. Most of these RV roof coatings stay flexible when they are cured. It means that if your RV roof moves, the coating moves as well. This adds to keeping your roof in good condition.
  6. Energy savings. These coatings insulate your roof, which means that you won’t have to crank up your AC or heating unit. This leads to less power used by these appliances and more money saved. In addition to that, it’s also good for the environment since you can cut on the emissions created.
  7. Environmentally friendly. A good RV roof coating will also be safe for the environment. They usually don’t have any toxic chemicals that could be harmful to nature or you. This makes them safe to use without worrying about your health or pollution to the environment.
  8. Reduced costs. Another advantage of RV roof coatings is that they can help you reduce the running costs of your RV. First of all, as we’ve already mentioned, it will help you reduce energy costs. And secondly, it will help you reduce costs on repairs and roof replacements. By protecting the roof and its structure from damage, you’ll have a lot less maintenance to do down the line. As a result, your roof maintenance costs will reduce significantly.

What is the difference: coating vs sealant?

Choosing between coating and sealant depends on how much and what you want to coat. If you want to create a protective layer over the entire roof, then you need the coating, which comes in a large can. On the other hand, if you want to just seal cracks and edges, a sealant would be perfect for the job.

How much RV roof coating do I need?

There are two factors that will determine the answer to this question. The first factor is the size of your roof and the second factor is the spread rate of the coating. So, first, calculate the surface area of your roof and then check the amount of area that the coating can cover.

How to apply RV roof coating?

Applying RV roof coating is a fairly simple process. Its application is very similar to applying paint. You just pour it over the top of your roof and spread it out with a paint roller.

  1. First, determine how much coating you’ll actually need. For this, measure the surface area of your roof. Then, buy a coating that would be enough to cover it. You can usually find in the specifications of each product the spread rate per gallon of coating. Also, keep in mind the recommended amount of coats since you’ll need more coating for four layers than for just two or one layers.
  2. Once you’ve got your roof coating, before you begin applying it, prepare the surface of your roof. It’s very important that it’s properly cleaned and dried. Make sure that there’s no dust, dirt, oils, poorly bonded paint, or other substance left on the surface. Otherwise, the coating will not be able to properly adhere to the roof.
  3. Some manufacturers recommend using their own roof cleaner. However, that’s not always necessary. You can also just pressure wash it and then wipe it down with some denatured alcohol.
  4. Check the instructions for any other prepping steps. In some situations, you’ll also need to use a primer before applying the coating. This can depend on the type of coating and the type of roof material you have.
  5. Once the roof is clean and dry, it’s ready for the coating. For the application, you’ll need a paint roller or a brush. Most coatings are ready for use right out of the can. However, some products require adding a catalyst first. Check your product for the instructions.
  6. When applying the coating, it’s best to choose an area to work in that has good shade and ventilation, which would help it to set properly. It’s also best to avoid intense heat and sunlight, which can make the coating uneven.
  7. After applying the first layer of coating, let it dry. The drying time will depend on the product. After this, depending on the coating you have, you might have to do another coat or even more. And once all the coats have been done, it’s time for curing, which can take anywhere from one to several days.
  8. These are general guidelines. However, your product might have unique instructions. It’s better to follow the manufacturer’s instructions, which would ensure proper application. It’s also important for the warranty since if you do something as not per instructions, it can void the warranty.

How many coats do I need for an RV roof repair?

The answer to this question depends on the type of coating that you have bought. Urethane and acrylic coatings are usually not as thick as silicon ones. Due to this, they usually require at least two coatings. Many silicon based roof coatings need just one coat for good results. You can check the product’s specifications, where manufacturers often mention the recommended amount of coats.

When applying urethane or acrylic roof coatings, also keep in mind that it’s better to do several thin coats rather than one thick coat. This way it will have the most effectiveness.
