Can You Paint Patio Slabs?

Patios are available in natural materials such as stone, sandstone, travertine, granite and slate. Patio slabs are also produced in concrete, porcelain and ceramic. Man made materials are also used for products such as block paving. It’s no wonder that customers often question whether paint can be used on any patio surface. 

Ask yourself, why do I want to paint my patio?

Is your patio the wrong colour?

If your patio is just the wrong colour, patio paints are only available in limited colours. Some people are unable to find the colour they want so they incorrectly use masonry paint. Masonry paint is far too soft a product to handle foot traffic.

Is your patio stained?

Promain have an extensive list of suitable cleaners and restorers for substrates. Have a look at our Patio Cleaners category to find the correct product for your patio type. Painting might not be the correct solution, if just a good clean will bring your patio back to life. For further advise on patio cleaners contact our technical team.

Is your patio slabs old and faded?

Paint can transform an old and faded patio rather than removing or replacing a patio completely which can be extremely expensive and time consuming. Painting is not just a quick fix, but can be a long term solution if the correct products are chosen.

Did you paint your patio in the past and it’s failed?

If someone or yourself has painted your patio in the past without the knowledge of how to do the job properly, the likelihood is that the paint may have failed quite quicker than you would have hoped. Old paint on patios can be removed with a suitable paint stripper. However, hiring a heavy duty power wash may be cheaper, easier, quicker and more fun! We recommend a minimum 180 bar pressure and 540 litres per hour flow rate.

Preparation: How Can I Paint My Concrete Patio Slabs?

Firstly, use a stiff broom to remove any debris. Then clean the patio with a suitable cleaner such as Centrecoat R09 Heavy Duty Cleaner. If your patio has moss or algae growth, we recommend using Centrecoat GS36. However, if you intend to use a jet wash, allow to dry thoroughly before application of the paint. If you patio slab has algae growth that is not removed by the Centrecoat GS36, we would recommend the use of Centrecoat BG R04 Hard Surface Landscape Cleaner.

Application: How Do You Paint Old Patio Slabs?

You can apply most patio paints with a good quality roller. We would recommend no larger than 12 inch wide.

Thin the first coat with 10%- 15% suitable thinner. Refer to the product data sheet for the suitable thinner.

Apply a minimum of 2 coats, with one 90 degrees to the other to ensure best coverage. Do not apply patio paint in full sun – follow our weather guidance here: What Are The Ideal Weather Conditions For Painting?

Always allow a minimum of 48 hours before using your patio to allow the paint to harden. Follow product data sheet guidance for the paint you are using.
