I think this liquid roof coating is very versatile because it works on any surface as long as it’s prepped clean and dry. For application, you can choose whether to brush, dip, roll, or pour.

Thankfully, I noticed no strong smell, so everything is good with my family. The coverage is just marvelous because the coat has hidden the lesions or cracks in my roof. It’s also worth noting that the drying time is quite fast — less than 24 hours.

One of the purposes of the Dicor EPDM roof coating is to protect the rubber roof from UV rays. As I have observed for many months, I think this claim is true. My EPDM rubber top was free of cracks and chalks, so it was leak-free for a long time.

Each application coats the RV’s roof with a durable polymer which makes an anti-static shield, minimizing the chalking and fighting dirt. Depending on the weather, the results last for 3-6 months.

What To Know Before Buying RV Roof Coatings

Choosing the right RV roof coating depends on several factors, like types and features. This section will explain each factor carefully, so you’ll make the right buying decision.

The Different Types Of RV Roof Coatings

In the midst of many brands of RV roof coatings around, it’s difficult to choose if you don’t even know what type they are. Let’s discuss the common types of RV roof coatings below.

• Acrylic

Acrylic is a durable and affordable elastomeric coating you can use for your RV roof. The high solid emulsion polymers make this type highly reflective and suitable for extremely hot climates. While this type of coating provides the greatest UV resistance, it might not fare well in terms of ponding water.

• Urethane

Urethane is more expensive than acrylics but more affordable than silicone. This type is the most durable, hence ideal for high-traffic areas. It also works well in resisting ponding water, as well as UV damage. The only drawback is that it tends to emit a strong odor during application.

• Silicone

Silicone provides the most benefits, but it’s the most expensive among the three types. This type is quick to apply since it can do with one coat and without a primer. Other benefits include high weather resistance, superb reflectivity, and resistance to ponding water. The downside is that it attracts dirt.

Benefits And Drawbacks Of RV Roof Coatings

An RV roof degrades over time, especially if it’s exposed to harsh weather conditions, so you’ll need an RV roof coating for protection. This type of product helps extend the life of the RV roof as it protects it from moisture, UV rays, mildew, and other elements. In most cases, these products prevent leaks and even fix minor crack issues.

If you use one with high solar reflectivity, it makes your RV interior more comfortable as it stays cooler during hot days. You get more energy savings as you run the air conditioner less. Also, it makes your RV roof look new and beautiful as it protects the roof from dust and mildew.

However, you need to prepare the RV roof before applying the RV roof coating. Some brands require a primer or activator, while others suffice with a detergent. Either way, you have to clean the surface before the RV roof coating application.

What To Look For In A Good RV Roof Coating

Finding the best RV coating is easy if you know what important factors to look for. Here are the things to evaluate when shopping for the right RV roof coating for your trailer.

• Compatibility

Firstly, you want the RV roof coating to work on your current RV roof. If you have a rubber roof, look for a rubber roof coating and not for a fiberglass one. The compatibility of the product can usually be found on the packaging label.

Some versatile brands offer compatibility to all roof materials — fiberglass, metal, and rubber. If you own more than one camper trailer, it’s wise to choose this type of product to save money.

• Ease Of Application

If you’re a DIY type of person, look for an RV roof coating that’s easy to use. You want a coating that needs little preparation and no complicated tools. The easiest RV roof coating won’t need a primer and can do well with a simple paint roller. It should dry fast, so you can apply the second coat faster.

The temperature can also be a determining factor in the application process. Some brands require a cooler temperature, while others require a hotter temperature. To solve all this hassle, look for a product that can be applied at any temperature possible.

• Safe Formula

You’ll want a safe formula to protect the health of your family and pets. Avoid products that contain VOCs and other harsh chemicals. To ensure the product’s safety, stick to US brands because they usually pass several tests before launching onto the market.

Most of the time, the smell can be a determining factor of its safety. If it reeks with a strong chemical smell, then it might not be safe.

• Maximum Protection

The goal of the RV roof coating is protection, so it’s only natural that you look for a brand that provides the best protection. Opt for brands that provide watertight seals to prevent future leaks. The best brands can even go as far as fixing minor cracks and holes on the roof.

To keep your RV interior cool, look for high solar reflectivity. The coating should be UV and moisture resistant, so it can endure all weather conditions.

• Warranty

We can’t always be sure of the product’s quality until we’ve used it. For quality reassurance, look for a product that offers a long warranty. It’s always comforting to find a product that provides a lifetime warranty or a money-back guarantee to ensure the longevity of the product.

• Price

In these hard times, the price plays a vital part in our buying decisions. You want to choose an affordable RV roof coating that doesn’t compromise the quality. Check your budget and find your options within that budget, so you don’t get into disarray with your expenses.

What Is The Best RV Roof Coating

The number one RV roof coating is the one with the best adherence to any RV roof surface. It should be UV-resistant to protect the RV roof from the damaging UV rays. Also, look for something that reflects the sun very well, so the interior stays cooler during hot days.

For this article, the best overall is the Heng’s Rubber Roof Coating because it adheres well to rubber RV roofs. It’s also sun-reflective and UV resistant. The best part is it comes at a reasonable price.

How To Seal A Camper/Trailer/RV Roof

The first step is to prepare the surface for application. Remove any debris or pretty much anything that might impede the coating process. Next, fix any defects using the best RV roof sealant to patch the holes and cracks on the RV roof.

Once the surface is cleaned, apply your favorite RV roof coating. Use a paint roller or any material that the product requires for application. Some products might suffice with only one coat, but doing a second coat after the first coat dries makes the protection more potent.

How Much Roof Coating Do I Need

It all depends on your RV roof’s condition. If your RV roof looks a little dull without any exposed black rubber parts, one coat might suffice. If it looks chalky or you find some cracked old rubber sealant, apply two coats.

Can I Use Flex Seal On My RV Roof

Yes, you can! Not only can this product be suitable for coating your RV roof, but also provide a watertight and pliable rubberized coating. The formula is developed to go on very smoothly on TPO, EPDM rubber, fiberglass, and metal roofs.

Conclusion

Applying an RV roof coating helps extend the life of your RV roof with its great weather protection. Some models can even help seal minor water leaks. All the products above are excellent, but Heng’s Rubber Roof Coating earns the top spot as the best RV roof coating because it provides excellent adhesion and UV resistance.

For high solar reflectivity, the Liquid Rubber RV Roof Coating can be a good alternative. It’s suitable for any RV roof surface. For RV rubber roofs, the Dicor RPCRC1 White EPDM Rubber Roof Coating is also a good choice.
