Both wooden and metal carports need refreshing over time. Painting a carport, whether wooden or metal, is an investment in durability and aesthetics. It provides effective protection against the elements. Rain, snow, sun and moisture can slowly degrade the structure – the right paint and painting technique can significantly extend its life.
In this step-by-step guide, you will learn:
- how to prepare the surface for painting,
- how to choose the right paints for wood and metal,
- how to technically paint so that it will last for years.
How to paint a carport yourself step by step – practical instructions
Painting a carport does not require specialised equipment or technical training – all you need is good organisation, the right choice of paints and space, and a few key rules.
Step 1: Choose the right paint or impregnating agent
What should you paint your carport with to ensure it will last for years?
Before you start painting, consider what to paint your carport with to ensure maximum durability and aesthetics. The choice of product should depend on the material (wood or metal), the finish (opaque or semi-transparent) and the weather conditions in which the carport will be used.
For wood:
- protective impregnating agent – an absolute must if you care about durability. This product deeply penetrates the wood and protects it against blue stain, fungi, mould, insects and moisture penetration.
- Impregnating agent for wooden carports is particularly suitable if the structure is located near plants, in the shade or in a damp environment.
- Acrylic or alkyd paint – ideal if you want to achieve full coverage and a stronger colour effect.Acrylic paints are flexible, environmentally friendly and quick-drying, while alkyd paints are more resistant to mechanical damage and moisture. This solution is particularly recommended for carports exposed to frequent contact with water (e.g. from gutters or roofs).
- Wood stain – a semi-transparent product that not only protects but also highlights the natural grain of the wood. Thanks to its UV filters, it protects the colour from fading. Wood stains are a great option if you want a natural effect and long-lasting protection.
Question: Does a carport need to be impregnated? Yes – every wooden carport requires impregnation, even if you plan to use opaque paint later. Impregnation acts as a protective foundation – without it, any exterior coating will wear out faster.
For metal:
- anti-corrosive paint (e.g. with a rust inhibitor) – mandatory as the first coat. It protects steel or sheet metal from oxidation, moisture and salt (e.g. in winter). Its task is to create a coating that insulates the metal from the elements. If you plan to paint a metal garage, start with this coat.
- Enamel for metal – this is the final finish that adds shine, colour and an extra layer of protection. Enamels can be matt, satin or glossy, and with proper application, they can last up to 7–10 years without needing to be renewed.
Step 2:
Before deciding whether full sanding is necessary, consider whether it is possible to paint the carport without sanding – in some cases, degreasing and priming alone will suffice.
Nevertheless, it is worth remembering that painting a dirty, damaged or damp surface is asking for disaster. Even the best paint or impregnating agent will not last long if applied to an unprepared surface. Therefore, before you reach for a brush, carefully inspect the entire structure.
For wooden carports:
- Clean the surface of dust, leaves, cobwebs, lichen and moss – preferably with a soft brush or pressure washer.
- Check for signs of rot, mould, blue stain or insect damage. If necessary, use a specialised fungicide or mould remover.
- If the wood is rough or cracked, sand it with sandpaper (100–150 grit) – this will increase the adhesion of subsequent coats.
For metal carports or garages:
- Carefully assess all surfaces – especially corners and joints, where moisture tends to accumulate.
- If you notice any corrosion, remove it mechanically with sandpaper, a wire brush or a grinder.
- Then degrease the entire surface with white spirit or a special metal cleaner.
BHB Expert’s opinion:
The most common mistake is painting on a surface that appears clean. Dust, moisture or microscopic deposits can completely ruin the effect of your work.
Step 3: Prepare your tools and secure the surrounding area
Good preparation of the work area is half the battle. Ensure comfort, safety and aesthetics – not only of the carport, but also of its surroundings. The right tools and organisation of space will help you avoid stress, mess and unnecessary corrections.
List of things to have on hand:
- Brushes and rollers – natural bristle brushes for glazes and oil-based paints, synthetic brushes for water-based paints. Rollers are suitable for large, smooth surfaces, such as metal garage roofs.
- Paint mixer – all paints and impregnants should be thoroughly mixed before use and during work, especially if you plan to paint a shed without sanding, where even coverage is important.
- Masking tape – use it to protect elements that you do not want to paint (e.g. hinges, fittings, mouldings).
- Protective film and ground cover – use them to cover plants, paving stones, concrete and nearby garden furniture.
- Gloves and dust mask – not only for sanding, but also for applying solvent-based protective products.
- Steps or a stable ladder – especially for high roofs or side panels of metal structures.
Question: What should I use to paint a metal garage or steel carport? It is best to use a sponge roller or spray – for larger surfaces, this will significantly reduce the time needed and improve the quality of the finish.
Tip: If you are painting metal, do not forget to apply an anti-corrosive primer. This is an absolutely crucial step, as failure to do so will result in the rapid appearance of rust spots, even under a thick layer of enamel.
Step 4: Paint in the right weather conditions
The weather is your silent partner (or your biggest saboteur). Exterior paints need stable conditions: no extreme temperatures, no moisture, no strong wind.
Here are a few rules to follow:
- Air temperature: ideally between 15 and 25°C. Too low a temperature can prolong drying time and weaken the adhesion of the paint. In hot weather, on the other hand, the coating may dry too quickly and crack.
- Humidity: preferably below 80%. Excessive humidity prolongs the drying process and increases the risk of streaks and unevenness.
- No rain or strong sunlight: paint on days without rain, dew or wind. Avoid direct sunlight, especially on metal surfaces, which can heat up quickly.
Drying too quickly can cause the coating to flake. Paint early in the morning or in the afternoon in the shade.
Step 5: Painting a carport step by step – technique and sequence
Whether you have a wooden or metal carport, the right painting technique is the key to durability and aesthetics. The order in which the coats are applied, the drying time and even the direction of the brush strokes all influence the final result.
For wooden carports:
- Prime the wood with a protective impregnating agent – preferably one that protects against fungi, blue stain and insects. The impregnating agent penetrates deep into the wood structure and protects it from the inside. Wait at least 12–24 hours until it is completely dry.
- Apply the first coat of paint or wood stain – following the grain of the wood. This will ensure that the product is absorbed evenly and does not leave streaks.
- Once dry (min. 12 hours), sand gently with 240-grit sandpaper. This will improve the adhesion of the second coat.
- Apply a second coat of paint or stain – this will provide protection and improve the appearance. In the case of stain, it will bring out the structure of the wood. If you are using opaque paint, it will ensure a uniform, durable colour.
For metal carports:
- Remove rust – using sandpaper, a sander or a wire brush. The surface must be clean and matt for the new paint to adhere well.
- Apply an anti-corrosive primer – this not only protects against further rusting, but also improves the adhesion of the topcoat.
- Apply two coats of metal enamel – paint designed for outdoor use, resistant to UV radiation and moisture. Allow the recommended drying time between coats (usually 6–12 hours).
Step 6: Check the effect and maintenance
Are you done? Not so fast. The last step is not just about admiring the final result – it is also about quality control and planning for the future. Even the best carport paint or protective impregnation needs regular maintenance to retain its properties.
After completing the work, carefully inspect the entire structure:
- Check for water stains, blisters, peeling paint or characteristic blue discolouration (these may indicate that the wood is reacting to moisture).
- If you notice any unevenness or unpainted areas, now is a good time to touch them up before the paint hardens completely.
- Plan an inspection every 2–3 years, especially if the carport is located in a sunny spot or exposed to heavy rainfall. Quick response to the first signs of wear (e.g. microcracks) will prevent the need for a complete renovation.
Daily care? All you need is mild soapy water and a soft brush or sponge. Avoid strong detergents – they can damage the coating. Once a year, it is also a good idea to clean the carport roof of leaves, moss and dust.
Question: Does a carport need to be re-impregnated after a few years? Yes – wooden structures in particular require a new coat of impregnating agent or a refresh of the protective coating every few seasons.
