A “granite garage floor” is usually not a layer of natural granite. In the Granite Garage Floors system, “Granite” is the name of a decorative flake finish: 1/4-inch chips are broadcast into a two-part 100%-solids epoxy base coat and covered with a polyaspartic topcoat. The granite-like appearance comes from the flake blend.
What the Brand Actually Publishes
Granite Garage Floors describes its namesake finish as decorative flakes broadcast to rejection into an industrial two-part 100%-solids epoxy base coat, followed by a UV-stable polyaspartic clear topcoat. The company also markets Stone, Quartz, Metallic and other appearances using related layered systems.
This Is a Useful Example of a Hybrid System
The floor is neither “just epoxy” nor “just polyaspartic.” One chemistry can provide the colored receiving/base layer while another is used as the exposed wear/UV layer. That is why Surface Blueprint recommends comparing the whole layer stack rather than choosing a contractor because one advertisement uses the word polyaspartic.
Questions to Ask About Any “Granite-Look” Floor
- Is “granite” merely the color/flake name, or is any mineral aggregate actually part of the system?
- What exact primer/base coat receives the flake?
- Is the flake a light decorative sprinkle or broadcast to rejection?
- What exact clear topcoat is exposed to tires, chemicals and UV?
- How are cracks, joints, oil and moisture handled before the decorative system?
- What does the warranty cover if a crack returns, a tire stains the topcoat or adhesion fails?
Do Not Buy the Floor by the Finish Name
“Granite,” “quartz,” “stone,” “terrazzo” and similar names can describe an appearance rather than the structural composition of the floor. Ask for product names, data sheets, layer thicknesses and preparation. A convincing color sample tells you almost nothing about the bond to your slab.
