Can You Paint An Enclosed Trailer?
Having an enclosed trailer can be great for a lot of different reasons, especially if you often haul anything from lawn equipment to livestock to the ‘King’ of hot rods, the Ford Model B. The fact that an enclosed trailer is actually enclosed will be very useful when it comes to keeping anything inside protected and out of sight.
Not only can you paint an enclosed trailer both inside and out, but it is advisable even on new trailers to add to the protection the they afford your cargo and for their own longevity. An epoxy paint is best on exterior and interior floors while interior walls can have a variety of finishes.
But while the enclosed trailer is there to protect whatever it is that is inside the trailer, one important aspect is the ability to protect the trailer itself. Enclosed trailers are often made of metals such as aluminum with it begin common to have wood floor decks inside.
Of course, even though aluminum may be durable, it can still wear down due to the effects of the elements such as rain and snow. This can also cause leaks to form which further compromise the structural integrity of the trailer.
So, when you want to make sure that your enclosed trailer is protected, what are the things that you can do to keep the exterior safe from the effects of the elements. Can you paint an enclosed trailer?
The good news for you is that, yes, you can paint an enclosed trailer. In fact, painting can protect both the enclosed trailer’s exterior and interior.

DIY Enclosed Trailer Painting
In most cases, enclosed trailer owners prefer to have a professional paint the trailers because it can take time, effort, and a bit of experience. But the problem here is that not everyone is willing to spend a lot of money to have an enclosed trailer painted. This is why it might be a good idea to learn how to paint an enclosed trailer yourself.
Here is what you need to do:
- Get a bucket and then fill it with water and the soap in the same way you would prepare to wash your car. From there, clean the trailer using a hose so that you will remove any mud, dirt, or even loose rust on the surface of the trailer.
- After that, use a sponge to make sure you get everything and that you remove any surface dirt that is on the enclosed trailer. Rinse the trailer thoroughly using a hose after cleaning it with the sponge.
- We suggest that you also sand the trailer before you wash it to remove any surface rust. Use coarse sandpaper to remove any of the light surface rust that you can spot on your enclosed trailer. After sanding the trailer, rinse wash it with the sponge and hose to remove any of the remaining residues on the surface. You have to make sure that there is no residual rust on the trailer before painting it.
- It is important to then let the interior and exterior completely dry before moving on to the next step.
- It is best to use a paint sprayer to paint your enclosed trailer to get all of the different nooks and crannies while saving time and effort. These can be rented from your locate tool rental store. Foam rollers are an option, but they usually end up creating a less than optimal finish without expert level experience.
- Primer is your first step with the sprayer if you are not using a paint specifically made to be a one step process. (I make recommendations in the next section.) Make sure that you follow the manufacturer’s direction in relation to the primer. Coat the entire enclosed trailer with the primer and allow it to dry for three or more hours before spraying the second coat.
- After the second coat has completely dried, you can use a fine grit sandpaper to ensure that the primer is smooth. Try to feel the coat with your fingers to tell which surfaces need to be sanded.
- Wash out the spray gun and make sure that it is completely dry before pouring automotive or other epoxy paint into it. Only choose these types of paint because this is what forms an protective barrier on the surface of your enclosed trailer to protect it from the effects of the elements. Think of it as something that is similar to the paint that is used on your car. (Note: clear coats like the one on your car if desired will have to be additionally applied. Most epoxy paints will suffice without a clear coat.)
- Make sure that you spray the paint in thin, even coats so that your trailer’s paint looks smooth. Allow the first coat to completely dry before applying the second coat. And you have to make sure that the second coat has completely dried off before you use the trailer
It is very difficult to use brushes or rollers on surfaces like these due to streaks, uneven applications, and bubbling that can occur. If you are not confident in applying paint with a paint sprayer, it is advisable to contact a professional to get an estimate. Having to fix some mistakes could cost nearly as much as having it done right the first time.

How Do You Seal An Enclosed Trailer Floor?
Another thing that is important in relation to an enclosed trailer is sealing it. Even though an enclosed trailer has a roof and walls that will protect anything that is inside the trailer, it is vital to note that water and excess moisture can still seep through the tiny openings on the sides of the trailer’s roof and damage the floor.
Not to mention, the things we keep in these trailers can sometimes cause as much trouble as the elements we are trying to keep out. This is why you need to seal an enclosed trailer.
Here is how you do it:
- When sealing an enclosed trailer floor, it is best to use an epoxy paint sealant because it tends to work well with the wooden floors that most enclosed trailers have.
- Follow the instructions of the epoxy paint sealant. In most cases, this involves having to mix two different parts into one. Mix the two parts in a bigger bucket.
- Another simpler option is a product like this Trailer Floor Coating that can be applied without mixing and using a foam roller.
- Cover the sides of the floor as well as the hinges between the ramps with tape. This will ensure that you do not get paint on those parts of the enclosed trailer floor.
- The best way to apply the paint on the floor is by using a long paint roller so that you do not have to duck to paint the enclosed trailer floor.
- After that, all you need to do is to pour some of the paint on one area of the floor. Use the paint roller to spread everything out all over a certain area to cover it with a thin coat.
- Simply do the same throughout the entire floor of the enclosed trailer paint while also including the ramp. Make sure that you wait for the paint to dry before you use the trailer, which could take up to 24 hours. You are also free to apply a second coat if you want, but it really is not necessary for you to do so if using the paint suggested above.
