Transform Your Outdoor Space: A Guide to Painting Patio Slabs

Painting patio slabs can transform your outdoor space, adding colour and personality to what might otherwise be a dull, grey area. Whether you want to paint paving slabs made of concrete or natural stone, this guide will walk you through the process, the tools you’ll need, and tips for maintenance and care to ensure your newly painted patio stays beautiful for years to come.

Why paint patio slabs?

Is painting patio slabs a good idea? Absolutely! Painting patio slabs is a cost-effective way to revamp your outdoor space without the need for a full renovation. It allows you to match your patio’s colour to the rest of your garden or home exterior, giving it a cohesive and polished look. A painted patio also provides a durable finish that can withstand foot traffic and various weather conditions.

Choosing the right paint

What paint do you use on patio slabs? For the best results, use masonry paint or concrete paint, as these are specifically designed for outdoor use and can adhere well to rough surfaces like concrete and stone. Masonry paint (or even better, a waterproff masonry paint) is ideal for surfaces that are not very smooth, while concrete paint works best on concrete floors and slabs. For a long-lasting and durable finish, select a high-quality, hard-wearing paint.

Tools and materials

Before you start painting patio slabs, gather the following tools and materials:

• Protective gear (gloves, mask)
• Patio sealer (optional)

Step-by-Step guide to painting patio slabs

Step 1: Clean the patio

How do you clean patio slabs before painting? Remove any dirt, moss or old paint from the patio slabs with a stiff brush. For a deeper clean use a jet wash or a patio cleaner. If you don’t have these use warm soapy water and a stiff brush. Make sure the surface is clean and free of debris.

Step 2: Surface preparation

After cleaning let the patio surface dry completely. This is important as any moisture left on the slabs can prevent the paint from adhering. If there are any cracks or imperfections, fill them in with a suitable filler and let it dry. For non-absorbing substrates or very smooth surfaces use an etching formula to help the paint adhere.

Step 3: Priming (Optional)

Do I need to prime patio slabs before painting? Not always necessary, but priming will help the paint adhere better and give a better finish. If you do prime, use a primer for masonry or concrete surfaces and follow the instructions.

Step 4: Painting

Apply a thin basecoat with a brush for the edges and a long-pile roller for the main area. Use an extension pole. After the first coat is dry for at least 12 hours apply a second coat, get in all the cracks and bumps. A third coat may be needed for full coverage. Let it cure for 24 hours before you walk on it.

Step 5: Sealing (Optional)

For extra protection apply a patio sealer once the paint is dry. This will prevent staining and give long term protection against the weather and foot traffic.

Costs and other considerations for painting patio slabs

Painting your patio slabs is a lot cheaper than replacing them. Here’s the breakdown:

Material Costs

1. Paint: The type of paint you use is key. Masonry or Epoxy paint is recommended for patio slabs as it’s durable and weather resistant. You’ll pay between €50-€200 depending on the size of your patio and the number of coats needed​​​​.
2. Supplies: You’ll also need other supplies like a concrete etcher, primer, brushes or rollers, painter’s tape, drop cloths and sealant. These will add up to around €100​​.

Labor Costs

• DIY: If you do it yourself it will take around 4-8 hours depending on the size of your patio. This is prep, painting and clean up time​​.
• Professional: In Ireland, a professional painter will cost between €10-€20 per square metre. For a small patio it will be 2-3 hours, for a larger patio up to 8 hours​​.

Maintenance and care

A painted patio needs some TLC to keep it looking fresh. Clean the surface with a mild patio cleaner or soapy water to remove dirt and debris. Don’t use harsh chemicals that can damage the paint. If you see any chips or wear, top up the areas with more paint to keep it looking uniform.

Weather resistance

One of the big advantages of masonry paint or concrete paint is weather resistance. These paints are designed to withstand rain, sun and everything in between so your patio stays looking vibrant and protected. Check the weather forecast before you paint and choose a dry day with mild temperatures so the paint doesn’t dry too quickly or not stick properly.

Painting patio slabs can breathe new life into your outdoor space, making it a more enjoyable and visually appealing area. By following these steps and choosing the right products, you can achieve a beautiful and durable painted patio that stands the test of time. Whether you’re looking to refresh old slabs or add a pop of colour to your new patio, painting is a practical and effective solution.
