How To Prepare Concrete for Painting? Simple Steps And Ideas

When it comes to concrete, painting may not be the first thing that comes to mind. But with the right preparation, painting concrete can be a great way to update the look of your home or business.

There are a few things to keep in mind when preparing concrete for painting, but with a little effort, you can achieve professional results.

Why Paint Concrete?

One reason to paint concrete is to improve its appearance. Chipped and flaked paint can make concrete look old and worn, but a fresh coat of paint can give it new life.

Painting is also a great way to protect concrete from weather damage and stains.

Another reason to paint concrete is for safety. Painted surfaces are easier to clean and maintain than bare concrete, which can become slippery when wet.

A fresh coat of paint can also make old and cracked concrete look new again, which can help prevent accidents.

Whether you’re painting a garage floor during garage conversion, basement floor, porch or patio—or even an interior concrete wall—proper preparation is key to getting the best results from your paint job.

Any good painting project starts with proper surface preparation, and that’s especially true when you’re dealing with concrete.

Concrete is a porous material, which means it can absorb paint, making it difficult to achieve even coverage and consistency.

In order to get the best results when painting concrete, you need to take some extra steps to prepare the surface. Here’s a look at what you need to do:


  • Water
  • Pressure washer
  • Etching solution
  • Bucket
  • Scrub brush

Preparing concrete for painting is a multi-step process that begins with power washing the surface to remove any dirt, debris, or mildew.

Once the surface is clean, an etching solution is applied to help the paint adhere better. After the etching solution has been given time to work, it’s rinsed off and the concrete is allowed to dry completely.

Once dry, any cracks or holes are filled in and then it’s finally time to start painting!

Steps: Pressure Wash, Etch, Clean, Rinse, Let Dry

Prepare Concrete For Painting

Pressure washing is the best way to ensure that your concrete is clean and ready for painting. Here are a few tips on how to pressure wash your concrete:

1. Start by wetting down the concrete with a garden hose. This will help to loosen any dirt or debris that may be on the surface.

2. Set up your pressure washer according to the manufacturer’s instructions. Make sure to use the proper nozzle for concrete surfaces – a 40-degree nozzle is ideal.

3. Begin pressure washing in a small area, using slow, even strokes. Work your way across the entire surface of the concrete.

There are a few key steps to take in order to prepare concrete for painting. First, you will want to etch the surface of the concrete.

This can be done with a muriatic acid and water solution. Simply mix one part acid to ten parts water, and apply it to the surface with a spray pump.

Be sure to wear gloves and eye protection while doing this. Let the solution sit for about 15 minutes, then rinse it off with a hose.

The next step is to clean the concrete thoroughly. You can do this with a pressure washer, or by scrubbing it with a stiff bristled brush and some soapy water. Once it is clean, you will need to let it dry completely before proceeding.

Once the concrete is dry, you will want to apply a primer specifically designed for use on concrete.

Tips: Wear Gloves, Safety Goggles

Wear Gloves, Safety goggles

If you’re painting concrete, you need to take some precautions to ensure that the job goes smoothly. Here are a few tips:

Wear gloves and safety goggles. This will protect you from getting any paint or chemicals on your skin, and from any debris that may be kicked up while you’re working.

Cover any areas that you don’t want painted. Use painter’s tape or drop cloths to protect baseboards, walls, floors, and furniture.

Bottom Line

Follow these Steps for Best Results

After completing all the necessary prep work, you are finally ready to paint your concrete. But before you start, there are a few final steps you need to take to ensure the best results.

First, mix your paint thoroughly. Be sure to stir it well so that all the pigments are evenly distributed.

Once your paint is mixed, do a test patch on a small section of concrete to see how the color will look and how it will hold up. If everything looks good, you’re ready to begin painting.

Start by painting the edges and corners first, using a brush or roller designed for use on rough surfaces.

Then fill in the rest of the area with a paint roller. Work in small sections and always keep a wet edge to avoid creating any lines or streaks in your finish.

What To Do Next:

If you’re going to paint concrete, the key is in the preparation. Follow these steps and your paint job will last for years.
