Indoor Sports Line Marking

Quick answer: Line Marking Australia marks indoor sports courts on timber, polyurethane-sealed and synthetic gymnasium floors, including basketball, netball, volleyball, badminton and futsal. On shared courts we give each sport its own colour, such as blue basketball, red netball, yellow volleyball and white badminton, and we match the paint to the floor coating so it doesn’t peel.

A recreation centre in Frankston called us about their gymnasium floor. The existing marking was confusing: five sports overlaid in similar colours with lines crossing everywhere. Players couldn't tell which lines applied to their game. Bookings dropped because nobody wanted to play on the confusing courts. We stripped all existing marking and redesigned the layout. Basketball in blue as the primary sport. Netball in red. Volleyball in yellow. Badminton in white. Each sport clearly distinguishable with logical colour hierarchy. The centre reported bookings increased significantly once players could actually understand the courts.

Why the floor coating matters

We made a paint compatibility error at a school gymnasium in Dandenong in 2018. We used standard floor paint on their polyurethane-sealed timber floor. The paint didn't adhere properly and began peeling within weeks. We had to strip, prepare, and remark with timber-compatible paint at our cost, around $4,600. Surface preparation matters.

Court dimensions follow each sport’s own rules: FIBA for basketball, Netball Australia for netball, FIVB for volleyball, BWF for badminton and FIFA for futsal. See our basketball court line marking page and our guide to multi-sport marking for indoor halls for layout ideas.

Standards and council rules we follow for indoor courts

• Each sport marked to its own rules: FIBA for basketball, World Netball Rules for netball, FIVB for volleyball, BWF rules for badminton and the FIFA Futsal Laws of the Game for futsal.
• Lines 50 mm wide for basketball, netball and volleyball, 40 mm for badminton and 80 mm for futsal.
• Paint that suits the floor coating, checked with the floor maker, so lines bond and do not lift at the next recoat.
• Each sport in its own colour, agreed with the venue.

Council and site rules on every court and field job

• Approval first. On council reserves, school grounds and club facilities we work only with the owner's written approval, plus a works permit where the council asks for one, and we follow the council's open space and reserve conditions.
• Safety paperwork. A Safe Work Method Statement and site induction under the Model WHS Regulations, with the work area coned or fenced off until the paint has cured.
• Insurance. Certificates of currency for public liability and workers compensation, at the level the council, school or club specifies.
• Working with children. On school and childcare sites our crews hold the state check, such as a Working with Children Check or Queensland blue card.
• Stormwater. No paint, wash water or grit goes into drains, in line with state EPA rules. We contain wash water and take waste away.
• Right paint for the surface. Court paint the surface maker approves, so your surface warranty stays intact, and grass-safe line paint on turf.
• Hours and bookings. Work is timed around council noise local laws and the club, school or council booking calendar.
