Difficulty: Moderately Challenging
Things You’ll Need:
- Concrete stain
- Pressure washer
- Non-residue cleaner
- Degreaser
- Brush or broom
- Hose
- Concrete acid cleaner
- Sprayer or roller
- Protective clothing
Step1
Purchase a concrete stain at a home improvement or paint supply store. Some stores offer both pre-mixed and custom color options.
Step2
Remove dirt with a pressure washer. Use a non-residue cleaner or degreaser to tackle tough stains. Scrub with a brush or broom and rinse.
Step3
Soak shrubs and grass around the patio with water to create a protective barrier.
Step4
Use a concrete cleaner with phosphoric or muriatic acid. Acid washing neutralizes the alkalinity so the stain will properly adhere to the concrete surface. Follow the mixing and application directions carefully.
Step5
Rinse the patio thoroughly with water and allow it to dry at least 48 hours.
Step6
Apply the concrete stain using a sprayer or roller on an extension pole. Wait 24 hours before applying a second coat, if needed.
