Work out your floor
Measure the length and width of the garage floor in metres and multiply them. A 6 m by 6 m double garage is 36 m².
What changes the price
- Old paint or coating. It has to be ground off first. How repairs work
- Damp concrete. A moisture barrier coat adds material and a few hours.
- Cracks and pitting. Small repairs are included. Big ones are quoted separately.
- Cove edges. Running the coating up the walls looks great and costs a bit more.
- Access. We need power and the garage empty on the day.
DIY garage floor paint vs a pro coating
An epoxy garage floor paint kit from a hardware store costs a few hundred dollars for a double garage. It's the cheapest way to change the colour of your floor. Without diamond grinding, it often lifts where the tyres sit within a year or two, and removing it later costs more than doing it properly the first time.
