- About 650 sq ft of slab with saw-cut joint lines
- Finish
- Charcoal dye, polished to a gloss
- Storage
- Wall shelves and a run of gray cabinets stay in place
- Estimated cost

Scope of work
Shelves and cabinets emptied, the slab degreased and ground through the diamond steps, cracks and saw-cut joints filled, one charcoal dye color worked in, a densifier, polishing to a gloss and a stain guard.
Project overview
In this example, the owner of a 2000s house in El Mirage parks a work truck in the three-car garage, and the bare slab shows every oil drip. A dark floor will hide small spots and look more finished.
Charcoal dye goes into the ground slab, and the floor is polished to a gloss. The cabinets and shelves are emptied first, and the work is done in strips so the shine matches across the wide room.
The goal
The goal is a dark, even garage floor that hides small drips and cleans with a mop.
Process
- Planning Floor checked for oil and cracks, color and shine agreed from samples.
- Grinding Slab degreased and ground, cracks and joints filled.
- Dye and polish Dye applied, densifier added and the floor polished.
- Guard Stain guard applied and the garage put back together.
Planning right
- A dark floor hides drips but shows dust and chalky footprints.
- Old oil can still leave a faint ring under the dye.
- A sample on your own slab shows how the dye will read.
- Say if you want the gloss toned down to satin.
