Metallic floors are the ones that go viral. Pigments suspended in the resin move as it cures and produce depth and marbling that genuinely looks like nothing else. They photograph beautifully.
They are also the finish we talk people out of most often, so here is the honest comparison rather than the sales version.
What each one actually is
Flake. Coloured vinyl chips broadcast into a wet basecoat to full refusal, then locked under two clear topcoats. The surface is a continuous field of chip. It has texture you can feel.
Metallic. Metallic pigment dispersed in a clear resin, manipulated while wet so the pigment migrates and pools. The result is smooth, high gloss and unique to that pour, because you cannot reproduce it exactly twice.
Where metallic is right
Dry, indoor, low traffic spaces where the floor is meant to be looked at rather than worked on. A showroom. A retail unit. An office lobby. A finished basement bar.
In those rooms it is genuinely impressive and nothing else does what it does. We install it, we like installing it, and we are not talking anybody out of it in that context.
Where it is wrong
A working garage, for three reasons that all follow from the same property.
Metallic is smooth. Smooth means slippery when wet, and a garage floor gets wet every time a car comes in off a February road.
Smooth also means it shows everything. A flake blend hides scuffs and tire marks in visual noise; a metallic pour has nowhere for a scratch to hide, and every mark reads against the pattern.
And smooth means repairs telegraph. A flake floor can be patched and blended because the field is continuous and busy. Matching a marbled pour in a small area is close to impossible, so a damaged metallic floor tends to need a whole section redone.
Anywhere outdoors. Same UV rules as everything else, plus the slip issue multiplied.
Over a slab with visible repairs. Metallic will show the outline of a filled crack. Flake will not.
Cost
Metallic is typically more expensive than flake per square foot, because it is slower and more skilled to install and there is more clear resin in it. It is not a budget option.
The short version
If the floor is going to be used, choose flake. If the floor is going to be looked at, metallic is worth every penny.
