The Best Garage Door Paints For Stylish Rust Protection

As an extension of your home, it’s only natural that you’ll want your garage to appear as attractive and impressive as the rest of your external décor.

And as the largest and most instantly noticeable aspect of any garage, its door should represent a priority for any houseproud homeowner looking to keep up appearances.

That’s especially true when it comes to maintaining the paint on your garage door. After all, a peeling or flaking paint job can create an unsightly spectacle that detracts from the rest of your property and immediately creates a negative impression of it, regardless of the effort that has gone into sprucing up the rest of your façade.

When it comes time to give the garage door a new coat of paint, many homeowners make the unfortunate mistake of simply using the same exterior wall paint with which they coat the rest of their property. In reality, that substance is incapable of lending the same kind of protection that garage doors need, given that they’re normally made from galvanised metal or wood.

Instead, it’s worth investing in a bespoke paint that has been specifically designed to freshen up your garage door. Luckily, there are plenty of products on the market which do exactly that. When deciding which one is right for your home, there are a number of things you should consider.

First of all, you should check that the paint is actually suitable for the surface upon which you wish to use it. You should also look out for one which is resistant to the elements and which offers good coverage and consistency when applying it to your garage door. You may also wish to consider formulas which include the primer within the paint itself, while the colour and price of the product you choose are not insignificant factors, either.

Armed with all that information, you’re ready to make a sensible purchase that suits your circumstances – and with the help of our handy buyer’s guide, that process just got a little easier.

We’ve handpicked our five favourite products from the vast array of options available online and in DIY stores to save you the time and effort involved in analysing them all.

Best Pick: Hammerite Garage Door Paint

Heavy-duty paint designed for garage doors which aims to reduce running on vertical surfaces.

Cost: £13.99

Hammerite is a respected brand in the world of DIY and offer a range of paints, varnishes and glosses to treat all surfaces. With this product, they have created a tough and long-lasting paint that is specifically designed for application on metal and wooden garage doors.

As well as being specific to the surface in question, Hammerite’s other big-hitting claim is that their formula won’t run on vertical surfaces. The veracity of that assertion is up for debate, with some buyers having reported that the paint is too thin to form a coat which stays in place on some surfaces. The instructions on the tin further muddy the waters, since they warn against stirring the paint before use, though doing so does seem to improve its consistency as long as you don’t overdo things.

Once the application issues have been overcome, the paint does give a strong finish which should stand you in good stead for several years, providing you take the time to apply several coats of the stuff. Its oil-based nature means it is toxic (so take care when using it), but it can be removed from brushes using white spirit without too much of a struggle.

The paint comes in tins of 750ml in size and offers coverage of up to eight square metres per litre, so there should be enough to give your garage door at least two good coats. There are also six colours to choose from, which allows you to pick the paint that most closely aligns with your existing décor.

Pros

  • Durable paint specifically designed for garage doors
  • Plenty of colours to choose from to set off your existing aesthetic

Cons

  • Too thin to live up to its claims of non-running on vertical surfaces
  • Oil-based nature makes it toxic to humans, animals and the environment

Value Pick: Johnstone’s Exterior Wood & Metal

Multi-purpose paint is thick on the brush and easy on the eye.

Cost: £9.99

Although not specifically designed for use on garage doors, this affordable exterior paint is suitable for wood, metal and plastic, meaning it works a treat for that purpose.

Its viscosity is both a strength and a drawback. The paint is extra thick in comparison to most of its competitors, even after a vigorous stirring of the tin before use. This means it is good for achieving a uniform appearance across the entirety of your garage door and discourages running, making it easier to apply than some water-based alternatives.

On the other hand, one concern is its drying time – depending upon the thickness of your coat, the surface of the substance to which it is applied and the ambient weather conditions around your home, you could be waiting days or more for the paint to completely cure. For best results, wait for a warm, sunny day to freshen up your paint job.

Johnstone’s paints come in two sizes (750ml and 2.5 litres), meaning you should have plenty to give your garage door a good few coats of the stuff. They’re also available in a variety of colours, from “Brilliant White” to “Black” via more imaginative shades such as “Sherwood” and “Victory Red”.

Pros

  • Very thick paint gives a strong and uniform finish
  • Different sizes and colours available

Cons

  • Incredibly slow to dry, with some buyers having waited several days without result

Fascinating Finishes Garage Door Paint

No-frills paint dries in two hours and lasts up to five years.

Cost: £17.25

Another multi-purpose product, this Anthracite Grey paint is suitable for use on all kinds of doors, including those made from wooden, metal, fibreglass, UPVC and more. Don’t be put off by its no-nonsense label – the paint offers a high-quality solution to covering your garage coat in no time at all.

That’s because its watery viscosity means it’s shower-proof inside 60 minutes, dries to the touch within a couple of hours and is ready to repaint with a second coat the following day. On the flipside, the runniness of the product may make it difficult to achieve a uniform consistency across the entirety of the door – especially with the initial coat – but that’s something that can be worked through as you apply more.

The manufacturer claims that their paint contains a primer within its formula, but those with a metal garage door are advised to treat the surface using a separate product before use – Fascinating Finishes also sell acid etch primer, which is especially useful for removing previous coats of paint that are damaged.

It’s easy enough to apply with a brush or roller and a 500ml tin should yield around six square metres of surface area, which is plenty to meet the needs of most garage doors with several coats, though it’s certainly not the cheapest product on the market.

Pros

  • Suitable for use on a wide variety of surfaces
  • Very quick drying

Cons

  • Watery viscosity means it can be challenging to achieve a uniform finish
  • Only available in one size and colour
  • Slightly more expensive compared to the competition

Dulux Weathershield

Quick-drying and long-lasting exterior paint from a reliable household name.

Cost: £21.99

As one of the most instantly recognisable names in home decoration, Dulux command a certain level of respect for their products – and a certain level of expectation, as well. Thankfully, their Weathershield range lives up to their high standards with an exterior wood and metal paint that offers great protection.

As the name suggests, the formula has been engineered to provide adequate resistance to all kinds of weather, be it snow, rain or shine, while it also deters the accumulation of mould, reinforcing the strength of the surface it adorns. This means it is less likely to accrue stains or become susceptible to flaking or peeling, so your garage door will look better for longer.

It’s advisable to use a primer before applying the paint itself, though fortunately the viscosity is ideal for achieving uniform brushstrokes that don’t run. After the application of at least two coats (giving sufficient time in between each to allow the paint to dry), you’ll end up with stunning results.

At 750ml in size and with coverage of up to 18 square metres per litre, Dulux is more expensive than some but still excellent value for such a reliable and robust product.

Pros

  • Great coverage and quick to dry
  • Exceptional results which last the test of time

Cons

  • Slightly more expensive than other brands – but still excellent value all the same

Rust-Oleum Universal Paint

Paint and primer in one impressive package that is as versatile as it is effective.

Cost: £26.71

This universal paint is very easy to work with, offers great versatility in which surfaces it can be applied to and returns eye-catching results every time. Equally as effective when used indoors or outdoors, a single tin can service several coats of paint for your garage door – with some leftover for touch-up jobs inside the home, as well.

For those with a wooden garage door, the primer contained within Rust-Oleum’s formula is adequate and the paint can be applied straight away. For those with a galvanised or non-ferrous metal door, it’s advisable to use a separate primer to prepare the surface and increase its adhesive properties.

The consistency of the paint is fairly thin, which makes application very easy but also results in running and dripping – ultimately creating unsightly stains on the floor that can be difficult to remove. It’s also oil-based and therefore toxic, so not an ideal choice for the environmentalists among us. Having said that, it is impressively quick-drying for an oil-based option, being touch dry within a couple of hours and ready for a second coat the following day.

On the plus side, it does come in an impressive array of 12 different colours, most of which come in a matt, gloss or satin finish (all are available in gloss). It also offers great coverage (9 square metres per litre) and is available in 250ml or 750ml tins, as well as an aerosol for small touch-up jobs.

Pros

  • Quick-drying for an oil-based paint
  • Plentiful array of colours on offer
  • Very versatile

Cons

  • Runny consistency can lead to dripping
  • Not ideal for the environment

How To Paint A Garage Door

As with any paint job, the preparation is just as important as the execution. When it comes to a garage door, this begins with dealing with the previous coat of paint before you can apply a new one.

Presumably, the reason you’re planning to freshen up the garage door’s appearance is that the previous paint job is now faded, cracked or peeling. If that’s the case, you’ll need to remove the old paintwork using a flat scraper and possibly use an acid etch primer to ensure all traces of the previous paint have been eradicated.

After the door is bare, you should then achieve uniformity across its surface with 180-grit sandpaper. Don’t rush this job, since a level surface is key to achieving a quality finish. Once the door has been sanded, you should clean it thoroughly using a sugar soap solution, taking care to remove all dirt, dust and other detritus from all facets of the door, including its hinges and edges.

Now it’s time to think about applying the paint. Before you do so, you should use masking tape to cover any fixtures (such as the handle and lock) that you don’t want to get covered in paint. You should also read the instructions of the paint you intend to use to ascertain whether the surface needs primed further before use. Some paints already contain a primer, some don’t. Be mindful, however, that all metal doors are likely to benefit from a separate primer, even if wooden ones might not.

Next, apply the paint to the surface of the door using a brush or roller. First tackle the edges of the door (opening it slightly beforehand), then allow those to dry before moving onto the rest of the door. Make sure you get into all the hard-to-reach places to ensure that no stone is left unturned. Wait for the paint to dry (consulting the tin to determine how long that should take) before applying a second or third coat.

Ta-da! Your garage door will now look brand new.
