How do I paint my caravan roof?

In this article, we will answer the following question: How do I paint my caravan roof? We will guide you to paint your caravan roof and also discuss the after-care of a painting job. 

How do I paint my caravan roof?

It is not difficult to paint your caravan roof, but you must put your safety first. The caravan roof can be hard to reach and most of them do not support the weight of a human being. Thus, you must be extra careful with this job.

First things first: the roof of a caravan is not a wall, so a brush and paint will not suffice. What you will need is masking tape, sponge sandpaper, soap and water, hardener, a paint gun and, of course, paint. 

 Here is a list of material that we need to make our motorhome the envy of the road:

  • Medium grit sandpaper. (If we want a more accurate job, we can use coarse-grained sandpaper and then fine-grained sandpaper for the details).
  • Polyester putty (if necessary if there are small flaws).
  • Masking tape.
  • Protection plastics.
  • Primer.
  • Paint spray gun (much more recommended than rollers, although both options work).
  • Water
  • Soap
  • Two-component polyurethane-based paint.

Ideally, use a two-component polyurethane-based paint, catalyst and thinner, which you will have to mix yourself. To know the ratio of the mixture, just take a look at the product’s technical sheet.

Before starting, it is best to do a small test of paint on a piece of the caravan, to make sure that it looks good and that the paint is compatible with the material of the body. If you have doubts, you can always consult a workshop.

Next, to paint your caravan roof, follow these steps:

  1. Choose a large place where you will not be disturbed or easily distracted. Be aware that you could stain other vehicles or even other people.
  1. Cover the unpainted parts, like window panes, with masking tape to protect them. 
  1. Carefully standing on a ladder, sand the entire area with a sandpaper sponge until the shine is removed.
  1. Clean the caravan roof thoroughly with soap and water so that no dirt remains, and then dry it with a cloth.
  1. Now you will have to pour the paint into the gun and give the roof a coat; When it’s dry, give it another one. Respect the drying time or you could spoil the result.

For the paint, we recommend you to use SUPER THERM®. This is a water-based acrylic paint used to insulate the roofs and facades of motorhomes, caravans and boats in order to protect, in summer, against heat by reflecting solar rays and, in winter, to avoid heat loss.

Things to keep in mind before painting the roof of your caravan

 If we think of our caravan as our home, it is logical that we want to treat it with care and leave it in the best possible way, both inside and outside. Doing a proper job will take us several days, but the result will last for years and we will protect our motorhome in a perfect way. In addition, we can save a lot of money, since it could cost us 1500-3000 euros in a professional workshop.

 It is highly recommended to carry out the entire process indoors, to ensure proper drying, that dust particles do not adhere, or that rain or snow spoil our work. But, if we have to do it outdoors, we must bear in mind that it is a process that generates suspended particles and can affect a large surface area. Painting is not recommended in extreme humidity circumstances or with a temperature below 16ºC, all to achieve optimal results.

Respecting the manufacturer’s instructions, both in the use and in the application of the products, will help us avoid unfortunate situations. Let’s not forget about it.

We must not forget to ask for the expert advice of a professional on the best type of paint and primer and its recommended amount depending on the model of our motorhome. At Juliá Pinturas we are aware of a large assortment of products thanks to years of experience, and we can advise on their correct application and use to always make our choice right.

Clean the roof of your caravan before painting it

Most people who get on their caravan do so to clean the roof or to do maintenance or to fix something. Few are those who go there for pleasure, but it can happen, in particular, to take a picture. Some even go so far as to use the roof as a terrace …

Remember that every time you step on the roof you run the risk of damaging it. If you stay upright, all of your weight will be concentrated in two points, under your feet. You may therefore sink the roof if you walk in a place without reinforcement.

A ladder or a stepladder should be high enough to clean the roof of your caravan. Besides, with a pressure washer, you can reach anywhere on the roof. Nevertheless, be careful about the pressure you send. Do not use too much pressure and keep a good spray distance.

But if you still want to get on your roof, keep it as short as possible. First, assemble the accessories you need. I am thinking of a brush, a broom or a blower. If after removing leaves and twigs you want to wet the roof, be very careful because the surface will be slippery. Stay on your ladder, stay safe.

How to walk on the roof of your caravan

Clearly, being able to climb on the roof of your motorhome depends on the material and the structural support.

Each roof has strong areas and weak areas. Knowing where the strong and weak areas of the roof area will help you navigate your way safely and not damage it.

  1. Walk on the strongest areas: The strongest part of the caravan roof is actually just above the cell walls. This is obviously where the roof has the most support. The further you move towards the centre, the more likely you are to feel the roof buckle under your weight.

So I advise you to stay at the edge of the roof, you should be able to reach the whole roof with a broom or a high-pressure lance.

  1. Avoid weaker areas: The weakest areas of a motorhome roof are in the centre and wherever the roof has been cut. The centre of the roof is furthest from the side support and therefore this area is the weakest, so do your best to avoid going there. I think it’s possible to stay on the ribs and still get to the centre with a broom or a high-pressure lance.

In addition, all areas of the roof that have been cut to allow the installation of a skylight, air conditioning and the like are also weak points. Avoid approaching these cut-out areas so as not to exert pressure and ultimately peel off the joints around these cut-outs.

  1. Use a ladder or stepladder to climb: If your motorhome is not equipped with an original ladder, take your ladder. Protect the angle under the ladder with a blanket and have someone block the legs and hold the ladder. If you are alone, wait until a partner joins you.

The bottom line

Painting the roof of a caravan is not an impossible job, but you must have some experience in painting! Ceiling painting work requires very specific and more technical equipment than painting a vertical wall. 

In any case, do not hesitate to ask for help from a professional when it comes to painting a caravan ceiling, as it could save you lots of time, energy and even resources.
