Painting a concrete floor is a great way to refresh a space and create a durable, smooth surface that’s easy to clean. Whether you're updating garage floor paint, patio floor paint, or painting a driveway, proper preparation is key to ensuring the concrete paint adheres well and lasts for years. Follow our expert advice to achieve a professional-looking finish.
Safety tip: Always wear the appropriate safety equipment (safety glasses, gloves and a mask, for example) and always follow the instructions for the product or equipment.
Before you begin, it’s important to determine whether the concrete has been previously sealed or coated. To test this, pour some water onto different areas of the floor and let it sit for about a minute. If the water soaks in, the surface is uncoated. If the water beads on top, this indicates that a previous coating has been applied. Identifying whether the concrete has been sealed will help you decide on the best preparation method for concrete painting.
To repair cracks, chips or holes in the concrete before your paint job, apply concrete filler smoothly with a putty knife and leave it to dry completely.
Priming is essential for ensuring strong adhesion and a smooth, even finish. In this case, the driveway has a previous coating, so we are spot-priming high traffic areas where the coating has lifted and applying a pre-coated primer to the rest of the surface. If you are spot-priming, apply two coats for extra durability.
Start by using a paintbrush to cut in around walls and edges where a roller can't reach. Then, using a roller with an extension pole, apply the concrete primer evenly across the entire surface. Work in small sections to ensure an even application. Let the primer dry for the recommended time stated on the packaging, which is typically a couple of hours, but always double-check before proceeding.
After applying the final coat, allow the paint to cure fully before using the area. Drying times will vary depending on the product and weather conditions, so check the manufacturer’s recommendations. Avoid walking on the painted surface or placing any furniture on the surface until the paint has completely hardened. If painting a driveway or garage floor, wait the recommended time before driving on it to prevent damage.
With the right preparation and application, your painted concrete floor will have a fresh, durable finish that lasts for years. For extra protection, apply a concrete sealer to the painted floor after curing – check the application instructions to make sure it’s compatible.

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.
When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
