Can You Paint Block Paving?

It’s a sad fact that the visual appeal of block paving reduces over time. When exposed to the weather your driveway or patio can start to look past its best, particularly as the sun bleaches away the color. 

However it can be a reasonably simple process to bring your trusty block paving a whole new lease of life. In this article we’re going to cover every aspect of this process and fully answer the simple question “can you paint block paving?”.

Why Paint Block Paving?

Can You Paint Block Paving?

There are numerous reasons why painting your block paving might make sense. The first and most obvious reason has already been mentioned; to make your block paving look like new once again. At the same time there are other benefits of painting your block paving that you might not have considered:

Update the Style – More creative readers might like the idea of giving their block paving a whole new look, rather than just taking the appearance back to what it once was. Growing in popularity, for example, is two-tone block paving. In these cases the outer bricks are often black or charcoal in color, while the central bricks or pavers are colored differently. Such an arrangement can give real impact, looking stylish but also incredibly neat. 

Reduce Efflorescence – Efflorescence is the appearance of mineral salts on the surface of brickwork that can appear when water passes through it. While it doesn’t do any harm to your block paving, there’s no denying that it can look unsightly. Painting can help to rid you of this issue. 

Inhibit Moss and Weeds – Moss and weeds don’t just look unsightly, but can also increase the chances of slips and trips in the winter months. At the same time, removing moss isn’t the most enjoyable job. Painting block paving makes the surface less appealing for these invaders.

Protection From Stains – Engine oil, antifreeze and other motoring or gardening chemicals can stain block paving, making it look unsightly. A fresh coat of paint helps to create a barrier on the surface, so that any spilled chemicals can more easily be washed away rather than causing a permanent blemish. 

As you can see, there are a whole load of reasons why painting block paving might make sense for you. 

What Is the Best Paint for Block Paving?

So if painting block paving makes so much sense, the obvious next question is which paint should you choose? What’s best?

Ironically, the best paint for block paving isn’t actually a paint at all. It’s a colored sealer. Let me explain…

By its very nature block paving tends to receive heavy footfall. If used on a driveway, block paving will have the extra challenge of vehicles constantly passing across the surface. This can mean that many paints struggle to keep up with the constant attack. 

Colored sealers, however, offer all the benefits of paint, but while also properly sealing the surface to properly protect it. 

Seeing as it is recommended that block paving sealer is re-applied from time-to-time anyway, choosing a colored sealer is really no more work than the ongoing maintenance that should be done anyway. The side benefit is you end up with a “looks like new” surface to enjoy for years to come.   

Can You Use Masonry Paint on Block Paving?

Masonry paint is designed to be applied to brickwork, concrete and other masonry surfaces. At first glance it therefore certainly can be used on block paving. However there are a few drawbacks that may mean this isn’t the best option. 

Firstly, masonry paint typically works best on low-traffic surfaces, such as brick walls. Used on floors, the constant friction combined with sitting water in winter, can significantly shorten its lifespan. You may find that the paint starts to wear through and flakes off far sooner than you’d hoped, leaving an appearance that is worse than when you started.

It is also important to consider the sand between the pavers. Paint doesn’t always work well with this sand, which can leave an unpolished end result. Colored sealers, in contrast, help to seal the sand in perfectly, giving a professional job even for inexperienced homeowners. 

When Should You Paint Block Paving?

There are two deciding factors about when you apply block paving paint and colored sealers. At its most basic, the surface should be clean and dry. 

The best time to apply a colored sealer is therefore when you’ve found the time to thoroughly clean the surface (removing dust, dirt, weeds, moss and so on). The surface should be allowed to dry thoroughly before application of the sealer. Furthermore, consider the weather for the next 24 hours or so, ensuring that no surprise rain showers are going to ruin the effect. 

How to Paint Block Pavers: Step by Step Process

Painting block pavers with colored sealant is reasonably simple. It can be considered a DIY job that most homeowners can achieve. While it is recommended you always follow the instructions on the colored sealer, as a general rule the following process can be followed:

Remove Weeds and Moss

The first step is to remove any foliage from the surface. There are many ways to remove weeds and moss, each with their own pros and cons. Some options can include weed wands, chemical moss removers, weed killers, or jet washing.

Repoint Joints with Sand

Weeds, when removed, can disrupt the sand between the joints. Even without this issue, sand can slowly work its way out of the cracks or wash away in heavy rain. Now is the opportunity to repoint those joints to ensure they’re in tip-top condition. Applying the sealer afterwards will help to hold the sand in position, resulting in a long lifespan. Simply apply kiln-dried sand and brush it evenly over the surface to fill all the gaps. 

Clean Dirt and Debris Away

Before applying the colored sealer the surface should be perfectly clean of dirt and debris. Using a stiff yard broom or a jet wash carefully clean the surface, so the sealer has a consistent flat surface to adhere to. 

Apply With a Roller or Sprayer

Assuming the surface of the block paving is now clean and dry, it is time to apply the colored sealer. Most sealers can be applied using a roller or a sprayer, or even with a brush, given enough patience. Most experts agree a sprayer is quickest and gives the most uniform end result/ The weakness is that you have less control than if you were using a roller, which can result in some sealer ending up on other surfaces. 

Allow to Air Dry

Most colored sealers require two coats. The first should therefore be allowed to dry thoroughly before a second coat is applied. For many modern colored block paving sealers this will only take a few hours, especially in hot weather. 

Apply a Second Coat

Once the surface is dry apply a second coat to ensure the surface is fully and uniformly treated. Lastly you’ll just need to wait for the second coat to dry before the surface can be used again like normal.

Conclusion

It is quite a simple job to update the appearance of block paving. Given a weekend of decent weather, most readers will be able to completely update the look of their block paving with a minimum of effort.

This is also one of those pleasant jobs that requires only a modest investment, no expensive workmen, and yet really adds to the curb appeal (not to mention safety and lifespan) of your block paving. 

Best of all, done properly, it’ll be quite some years till you need to consider painting your block paving again.
