Can I Use Garage Floor Paint Outside?

Dull concrete surfaces like your garage floor, patio, driveway and garden exteriors can look so much better with a lick of paint. So can you use garage floor paint outside?

Painting concrete gives the advantage of allowing areas to be easily cleaned up, maintained and protected. Paint also protects the surface as it adds a special coating that resists damage through stains, moisture or environmental damage. 

The Short Answer

It depends on the surface you wish to do up outside. In some cases, yes, you would be able to use your garage paint for the job, and it’d work. The matter on hand is that you need to make sure that you have the best garage floor paint that is the right kind and will work for your project outside. Simply put, there are a few kinds of paints that support concrete jobs. These are:

  • Latex 
  • Epoxy 
  • Acrylic Latex 

What Garage Floor Paint Can Be Used Outdoors?

The best paint tends to be epoxy garage floor paint. This kind is designed as a reliable solution for concrete garage floor paint or concrete floors. The chemical binders in the paint can withstand harsh treatment from a car, for instance, so it has durability, making it perfect for garage floors and car showrooms. It also shows wonderfully glossy results on the surface. 

It’s most likely you have a colour that’s universally used, such as grey garage floor paint. That would work on concrete areas like your patio, for instance. 

However, it comes with a problem of being somewhat hard to apply as it requires some solution mixing. Along with this, it’s dense and can start running down a wall before it dries, so if you intend to use it on a wall outside, you may end up with patchiness and streaking, giving you an uneven coating. 

This goes for all vertical surfaces such as walls and foundations. So if your intended use is for a vertical surface, you may need to purchase a concrete block paint made for concrete walls. 

You could select an acrylic latex type suitable for outdoor use that can put up with the worst of the weather effects, thanks to acrylic resins. It comes with the advantage of being less dense than the epoxy kind, so it’s easier to handle and is also available in a wide range of colour options. 

Can You Paint Concrete Floor Outside?

If you intend to use Epoxy paint on a floor outside, the results will be solid (no pun intended) – you can rely on it because you’ll get a rock-solid finish that’s resistant to moisture and stains. 

Epoxy types have the advantage of being ideal for masonry areas like outside floors and garages because they don’t crack with the exposure to the sun or cold weather temperatures. 

You might already have some black garage floor paint or another muted colour on hand. These universal shades are multi-use and can be used across all your concrete floors around your house.

Usually, latex paints can fade and crack after some time due to rain or moisture getting into the concrete and soaking into its pores. So for a floor, an epoxy or an acrylic-latex type would be a great choice as it’s protecting and relatively low maintenance, requiring fewer repairs and holding up for longer.

When choosing paints for your concrete floor outside, consider a few things for the best buy:

  • Weather Resistance: Epoxy puts up with weather challenges better than the other two. It just comes with slight difficulty in the application stage.
  • Finish: If you want a glossy look, epoxy types come with this. Having a glossy finish also makes cleaning easier due to the slip, and you’re less likely to notice scratches. The acrylic types have a more matte finish and are non-slip, making them a good choice for a patio or garden floor. 
  • Longevity: Epoxy paint is the longest lasting. The other two do perform well but might need re-applying every year or so. 


Can I Paint My Patio With Masonry Paint?

Yes, masonry paints are the acrylic-latex type that can be used on many areas like patios. They can leave your patio with a clean, matte finish. They’re made to work with rough textures and come with the advantage of having a wide range of colour options and durability. They’re also moisture vapour-permeable, so they do well in tricky weather conditions. 

A patio floor of concrete slabs, slate, stone or laid concrete will adhere well to this type. Ensure that the one you select for your patio surface is non-slip, and follow these steps before painting to ensure you achieve the best finish.

  1. Start by cleaning using a pressure washer or a wire brush to get rid of any debris, dirt and unevenness. You can use some acid products, which are available in home improvement shops, to help dissolve grime away. 
  2. Fill any cracks with sand or a concrete sealant, ensuring you apply an even coating over the areas of the floor most needy of it and repair any loose slabs. Make sure you follow the manufacturer’s recommendations of the sealant product. 
  3. You can now start painting, using a paint roller or brush, and depending on how porous your patio floor slabs are, you may need to apply an extra coating or two for total coverage.
  4. Be prepared to re-do the garage floor paint outside about once or twice a year.  

Final Thoughts 

Using the right paint goes hand in hand with the space that you wish to do up outdoors. You could use your garage paint on areas that aren’t vertical. If you find that perhaps you want to try it out anyway, always patch test an area that’s not so obvious and see how it turns out. 

If you know how to paint a garage floor, the same technique will work on other concrete areas. Just bear in mind the factors we explained above, such as the weather resistance and the finish you’d like. 

You may be better off selecting one of the acrylic latex types hugely available in the market. These are versatile, made for easy applications and suitable for many concrete masonries, internal and external to your house.

You don’t have to have much experience to begin your new painting project. Just follow a few guidelines to ensure you have the most satisfying outcome.
