Can you Paint Patio Slabs?

Patios come in stone, sandstone, concrete and slate. It’s no wonder that customers often question whether paint can be used on any patio surface. 

Painting your patio is doable, but precautionary steps need to be followed, as painting concrete can be a problem if specific measures aren’t taken. Avoid the problems and follow the suggestions recommended below.

Can I Paint My Concrete Patio Slabs?

Yes, you can! Using a paint roller, painting your patio can be done similarly to painting walls and floors in the home. You just have to give your patio space a deep clean before starting, using a jet washer, wire brush attachment and hose to remove the layer of grime – plan to do this in warmer months so that everything dries quickly too. 

Most patio paint available on the market can work on the common types of patio surfaces. The majority of patio paint is made to work with concrete.

Anti Slip Solutions

When selecting paint for your slabs, be sure to check if it’s non-slip. Whether it’s masonry concrete paint, water or oil-based paints, or concrete paints with waterproof features, they all have the advantage of being long-lasting. They’re also made to work with rough textures and come in a wide range of colours. 

Moreover, these patio slab paints are also moisture vapour-permeable which means they deal well with wet weather conditions. Once they’re set, they seal themselves onto the surface, making them hard to remove. 

Can You Paint Old Paving Slabs?

Yes, you can. Just make sure when purchasing paint that it’s for exterior-grade paving slabs. 

Most of the patio paints available will work well on paving stones as these masonry and concrete paints are thick and durable, designed to be used on concrete but also easy to apply with a paint roller or brush. 

Paving slabs can have a coarser texture; in that case, you might have to apply two coats of paint to have a lasting finish. 

Can You Change the Colour of Patio Slabs?

Aside from using patio paint to colour your slabs, you can opt to apply a dye to it using a single based colour or multiple colours. Staining your deck with dye is an alternative way of colouring your slabs if you don’t wish to paint. This gives a more natural look as the stain can deepen the colour of your current stones. 

The dye will settle on the stone’s surface more translucently than paint – that is more opaque. Regarding which one is better, there’s no solid answer. Concrete stains take less work than paints and dry quicker, whilst paint takes more work and dries relatively slowly but offers protection for your patio. 

If your slabs are covered with a sealer, the stain won’t adhere to it, so you need to bear that in mind if you want to use a dye. Depending on what kind of look you wish to go for, you can choose the one that fits your patio the best. 

How Do You Paint Old Patio Slabs?

Follow these steps to get the most satisfactory outcome from your patio slabs. All these steps are crucial to achieving a smooth finish for your paint:

  1. Begin by getting rid of any moss and weeds by hand or using a herbicide about a fortnight before cleaning. 
  2. Repair any cracks in the stone by filling with a masonry crack filler to allow the product to dry between applications. Once fully dry, sand the area with sandpaper and clean up the dust. 
  3. The best patio cleaner is a pressure washer/hose. This, along with a wire brush, gets rid of any debris, dirt and unevenness. Use some Trisodium Phosphate solution (TSP), which will remove surface grime, trapped dirt and grease. Follow the manufacturers’ recommendations on the bottle. You can use a stiff brush to scrub the concrete, wash it thoroughly, and let the surface dry.
  4. You can use some self-etching solution. It will give the concrete a sandpaper-like finish that will make the paint stick on better.
  5. Rewash the surface with a hose and let it dry completely before moving on to priming.
  6. You can now apply some exterior grade concrete primer to give your patio a coating of protection from any cracks by acting as a bonding agent between the concrete and your paint. Finally, make sure you let it dry after applying it with a paint roller. 

What Do I Buy?!

Patio paints come with a wide range of choice. When buying, always check that the product is anti-slip. You can opt for: 

  • Outdoor concrete paints work well as floor paint and provide resistance against the elements. They come with waterproofing sealant features so your paint will resist water and grease well, giving your patio area a clean finish. 
  • Water and oil-based exterior grade paints that are designed for concrete floors like patios and porches are a good choice as they can take a lot of wear and tear. 
  • Masonry paints are often used to paint garage floors and concrete walls.

After applying your paint and letting it dry, you can opt for a wet look patio sealer. This can give your stones a colour-enhancing, wet-look finish. It also serves to protect your patio from stains.

Ending Remarks

Your patio is the gateway to your home. It can be easily given a makeover with some paint that can also emphasise other landscaping features in your garden or surroundings. Painting your patio is possible, and it’s crucial to take the preparatory advice offered above to get the best out of your next DIY project.

Cleaning your paving area will prolong your slabs’ life, and adding paint on top will add value and protection to your patio. You have a variety of choices and colours to choose from. You can choose a natural look if you prefer, with concrete staining, or go for something more vibrant and use concrete exterior grade paints to create a different effect.

As a general rule of thumb, you should clean, repair, wash, add your solutions and then set out to prime and paint. Make sure you don’t rush any of the steps. Good discipline will aid in your success for your next garden landscaping project.
