A concrete surface has no figure
That origin is the whole practical difference. Concrete has no grain, no vein, no direction and no point of interest, so a printed concrete face has nothing for an eye to lock onto and compare.
Which is why it hides things other prints cannot. The joint disappears into an even mottle where a veined print gets cut across by it, a repeated face is far harder to spot, and a tile can be laid any way round because there is no right way up.
Where the marks in the print come from
Look closely at a concrete look tile and the marks have sources. The broad tonal drift is uneven curing, where the slab dried faster at the edges than the middle. The fine speckle is aggregate showing through a thin layer of paste.
The occasional darker patch is where water pooled, and the faint straight lines are formwork. A good print carries all four at different scales, which is what separates one that reads as concrete from one that reads as gray paint.
Matte carries this range
Matte is the finish on most of this range, with honed and lappato groups behind it and a few faces whose finish field reads anti-slip.
The dominance of matte is not a style preference. Concrete is a matte material, so a shine on it is a contradiction the eye picks up immediately, and the only shine that works on the effect is a partial one.
Lappato, the partial polish
Lappato is worth understanding because it is specific to porcelain and it has no equivalent in stone. The face is ground back only at its high points, so the raised areas come up to a shine and the hollows stay matte.
The result is a surface that changes as you move past it: it catches light in patches and stays dull between them, which is closer to what a power-troweled concrete floor actually does than either a full polish or a flat matte. It is the finish for a concrete look that has to carry some light.
12x24 and the larger formats
12x24 carries the size list here, then 12x12 and 24x24, with 24x48, 18x36, 6x12 and a set of metric formats written in inches behind them.
Large formats suit this effect better than any other, for the same reason the print hides its joints: a concrete floor in reality is a continuous pour with no joints at all, so the fewer lines in the tiled version, the closer it gets. The limit is the floor underneath, which has to be flatter as the tile gets longer.
Concrete look mosaics and the shower
A substantial group here is supplied as mosaic sheets, which is the answer to a shower pan: it falls toward a drain in two directions at once, and small pieces on mesh settle into that shape while a large format fights it.
A concrete look is a good fit for a bathroom for a further reason. It is the one effect that looks the same on the wall, on the floor and in the pan, so a whole enclosure can be done in one face. The enclosure belongs to porcelain shower tile.
The outdoor pieces
A small 20 mm group comes with a pool coping, which is paving: structural pieces bedded in sand or gravel, or carried on pedestal supports, with no adhesive anywhere in it.
Concrete is an outdoor material to begin with, so the effect needs no argument on a terrace. Porcelain pavers is the full outdoor range.
Where a concrete look belongs
An open plan floor, a kitchen, a bathroom, a hall, a commercial interior and anywhere a surface is meant to recede. It is the effect chosen when the floor is not supposed to be the subject of the room.
For the material across the catalog, porcelain tile is the full range, and gray porcelain tile is the color most of this effect sits in.
