Preparation: Clean the driveway with a bleach-and-water solution, pressure wash, and acid wash
Before painting your driveway, it is important to prepare the surface by cleaning it with a bleach-and-water solution, pressure washing, and acid washing. This will ensure that the paint adheres properly and the final result looks neat and professional. Here is a step-by-step guide to help you through the process:
Clean the driveway with a bleach-and-water solution
Create a diluted bleach solution by mixing bleach with water. The exact proportions may vary depending on the specific instructions provided by the bleach manufacturer. Use a stiff brush or a scrubber to apply the solution to the driveway, scrubbing away any visible stains, tyre marks, or discolouration. This step will help remove any built-up grime, oil stains, or other contaminants that may interfere with the painting process.
Pressure wash the driveway
Pressure washing is an effective way to deep clean your driveway and prepare it for painting. Start by clearing any loose debris, such as stones, dirt, toys, or bikes, from the driveway. You can use a leaf blower or a broom for this step. Move potted plants and outdoor furniture away from the area you'll be working in. Cover any nearby walls or doors with a tarp and painter's tape to protect them from accidental spray or flying debris. If there are in-ground plants close by, consider covering them with a tarp as well, being mindful not to leave them covered for too long to avoid limiting their air supply.
Connect the spray wand to the pressure washer using a pressure hose, and connect the washer to a water supply using a garden hose. Select the appropriate nozzle for your task—use a low-pressure nozzle for applying detergent and a high-pressure nozzle for rinsing. Before starting, test the pressure washer on a small, inconspicuous area of the driveway to ensure it won't damage the concrete. Begin pressure washing at the higher end of the driveway, working your way down in the direction of water flow. Point the spray wand at the surface and pull the trigger, sweeping the nozzle steadily back and forth and overlapping each stroke by several inches. Once you've applied detergent to the entire surface, let it stand for about 15 minutes before rinsing. Always be mindful of your surroundings when pressure washing, and avoid pointing the spray wand at people, pets, or plants.
Acid wash the driveway
Acid washing, also known as acid etching, is a crucial step to prepare concrete surfaces for painting. It helps promote adhesion so that the paint or epoxy coating will adhere properly and not chip or peel over time. Before beginning, ensure you have the appropriate safety gear, including rubber boots, acid-resistant gloves, vapor-proof goggles, and a respirator with an acid-grade filter. Choose the right type of acid for your project and experience level—sulfamic acid is recommended for amateurs, while phosphoric acid is suitable for areas with acid-vulnerable materials. Muriatic acid, on the other hand, is only recommended for professionals due to its intense fumes and strong corrosive properties.
Mix the selected acid with water in a plastic bucket, always adding the water first and then slowly pouring in the acid to prevent a violent reaction. Consult the manufacturer's guidelines for the correct proportions. Hose down the driveway to dampen the concrete, and wet surrounding objects like bushes, trees, doors, and walls. Keep the concrete wet throughout the process. Sprinkle the acid solution onto the surface using a plastic watering can. Be cautious and follow safety instructions, as acid washing can be dangerous for people, pets, plants, and metallic objects.

Paint choice: Epoxy-based paint is durable and can be mixed with colourful chips
Painting a driveway is a relatively easy DIY project. However, it is important to note that paint can start peeling off over time, and it can be challenging to maintain. To avoid this, proper surface preparation is key. The driveway should be pressure-washed and cleaned with a bleach-and-water solution, and then rinsed with clean water. It is also recommended to acid wash the driveway using muriatic acid diluted with water while wearing protective gear, such as gloves, goggles, and a respirator.
Epoxy-based paint is a durable option for driveway painting. It is resistant to scratching and staining and can withstand various forms of abuse, such as dropped tools, leaking fluids, or chemical spills. Epoxy coatings can also be combined with additives like plasticisers or reactive diluents to enhance their performance. These additives help the epoxy resist heat without discolouring and prevent slipperiness when wet.
Epoxy-based paint can be applied using a roller or squeegee, and it is available in major hardware stores. For a 40 x 15 ft driveway, approximately 3 gallons of 2-part epoxy are required for one coat, costing around $200. If you desire a coloured driveway, epoxy-based resins can be mixed with colourful chips to create a unique and durable surface.
It is important to note that epoxy coatings can be affected by moisture, leaks, and drainage issues. Therefore, it is crucial to ensure that the driveway is completely dry before applying the epoxy coating. Additionally, avoid driving on the driveway for at least 7-10 days after painting to allow the paint to cure properly.

Application: Use a roller brush and apply at least two coats
Painting a driveway can be a good idea for specific situations. It offers aesthetic improvements, helps protect the surface from UV damage and stains, and can extend the driveway's life span. It is a relatively easy DIY project.
Before painting your driveway, you should thoroughly clean it. Use a broom to sweep away rocks, pebbles, leaves, dirt, and any other debris. Then, use a pressure washer to get rid of bacteria, weeds, chalk marks, and other difficult stains. You can mix 1/4 cup of trisodium phosphate cleaning agent or another driveway-safe alternative with 1 gallon of water and apply it to your driveway with a brush. Be sure to wear latex gloves to protect your skin.
Once your driveway is clean, allow the surface to dry completely before painting. Tape the edges of your driveway and use a roller brush to apply the paint. Epoxy-based paint is recommended for concrete driveways. Depending on the epoxy coating you use, you may need to wait 24 to 48 hours between coats. Apply at least two coats of paint, allowing each coat to dry completely before applying the next. The drying time will vary based on weather and humidity levels. Apply the second coat in a cross direction to the first coat to ensure color uniformity and a more even finish.
After painting your driveway, consider sealing it with a high-quality urethane sealer. This will add a protective layer against UV rays, rain, and wear and tear. Resealing your driveway every few years will protect the paint and enhance its colour and lifespan. Regular maintenance, including cleaning and touch-ups, will help keep your painted driveway looking its best.
