From preparing your concrete surface to choosing the best paints and tools, and finally applying the markings with precision, this guide will equip you with the knowledge to create a stunning, long-lasting basketball court that players of all ages will enjoy.

Preparing the Concrete Surface

Before any painting begins, the concrete surface must be thoroughly prepared to ensure proper adhesion and a durable finish. Start by inspecting the court for cracks, chips, or uneven areas. Repair any damage with a concrete patch or filler and allow it to cure fully. Cleaning the surface is critical; remove all dirt, grease, oil stains, and loose debris using a pressure washer or a stiff-bristled brush combined with a concrete cleaner or trisodium phosphate (TSP) solution.

After cleaning, rinse the surface thoroughly with water and allow it to dry completely. Moisture in the concrete can prevent paint from adhering properly, so ensure the surface is dry before proceeding. If the concrete is new, wait at least 30 days before painting to allow the curing process to complete.

To improve paint adhesion, consider etching the concrete with a muriatic acid solution or a commercial concrete etcher. This creates a slightly rough texture that helps the paint bond better. Always follow safety guidelines when handling acids, including wearing gloves and eye protection, and rinse the surface well after etching.

Choosing the Right Paint and Tools

Selecting the appropriate paint is essential for durability and appearance. Use high-quality acrylic latex paint specifically formulated for outdoor concrete surfaces, as it offers good flexibility, UV resistance, and weather durability. For basketball courts, some manufacturers provide specialized court marking paints designed to withstand heavy foot traffic and harsh weather.

In addition to paint, gather the necessary tools to achieve clean lines and a professional finish:

  • Painter’s tape or line marking tape for crisp boundaries
  • Measuring tape and chalk line for accurate layout
  • Stencils or templates for logos and key markings
  • Rollers with medium nap for large areas
  • Brushes for detailed work and edges
  • Spray paint or line striping machines for quick and precise lines

Marking the Court Layout

Accurate measurements and clear markings are crucial for a regulation basketball court. Use a measuring tape and chalk line to draw guidelines on the concrete before painting. This helps prevent mistakes and ensures symmetry.

The main dimensions for a standard half-court basketball court are:

  • Court length: 50 feet
  • Court width: 42 feet
  • Free throw line: 15 feet from the backboard
  • Three-point line: 19.75 feet from the basket in recreational courts (or 22 feet in professional)
  • Key (paint) area: 12 feet wide

Use stencils or templates for circles such as the center circle and free throw semicircle to maintain precision.

Court Element Dimension Notes
Half-court Length 50 feet Common residential size
Half-court Width 42 feet Standard for half-court play
Free Throw Line 15 feet from backboard Measured from the face of the backboard
Three-point Line 19.75 feet Recreational courts; can be extended to 22 feet
Key Width 12 feet Width of the paint area

Applying the Paint

Begin painting by applying a primer coat if recommended by the paint manufacturer. Primer enhances adhesion and longevity, particularly on porous concrete. Use a roller to spread the primer evenly, working in small sections to avoid drying lines.

Once the primer dries completely, apply the base color for the court surface. This is typically a muted green, blue, or gray, which contrasts well with the white or yellow court lines. Use a roller for large areas and ensure the paint is applied uniformly. It may require two coats for full coverage, allowing sufficient drying time between coats.

After the base coat has dried, use painter’s tape or line marking tape to outline all court lines, including boundary lines, the key, free throw, and three-point lines. For best results, apply the tape carefully to avoid paint bleeding underneath.

Next, apply the line paint, which is often white or yellow for visibility. Use a small roller or brush for precision, or a line striping machine if available. Multiple coats may be needed for opacity and durability. Remove the tape immediately after the final coat while the paint is still slightly wet to prevent peeling.

Finishing Touches and Maintenance Tips

After all paint has dried thoroughly, inspect the court for any imperfections or missed spots and touch them up as needed. Adding a clear acrylic sealant designed for outdoor concrete can provide extra protection against wear and weather.

To maintain the court’s appearance and longevity, follow these guidelines:

  • Clean the surface regularly using a broom and mild detergent
  • Avoid using harsh chemicals or pressure washers that can damage the paint
  • Reapply line paint or sealant every few years, depending on usage and wear
  • Address cracks or damage promptly to prevent further deterioration

Consistent maintenance will keep the basketball court looking professional and ensure safe play for years to come.

Preparing the Concrete Surface

Proper preparation of the concrete surface is crucial to ensure the paint adheres well and lasts over time. Begin by thoroughly cleaning the area to remove any dirt, debris, or stains that could interfere with the paint. This involves:

  • Sweeping and washing the court with a stiff-bristled brush and a mixture of water and mild detergent.
  • Using a pressure washer to eliminate stubborn grime, grease, or algae buildup.
  • Allowing the surface to dry completely, as moisture can prevent proper paint adhesion.
  • Inspecting the concrete for cracks or uneven spots and repairing them with concrete patch or filler to create a smooth, level surface.

After cleaning and repairs, etching the concrete can improve paint adhesion, especially if the surface is smooth or sealed. This can be done using a concrete etching solution or muriatic acid, following all safety precautions and manufacturer instructions. Rinse thoroughly and let dry before proceeding.
