12 x 24 in Prima Charcoal Polished Rectified Unglazed Porcelain Tile
Item 4500-0562-1-8PC-MC
which finish?
Polished is glossy and reflective. It shows the most veining and light, and is slicker when wet, so check the slip rating (DCOF) before using it on a bathroom or shower floor.
Honed is smooth and matte. Softer, more natural look, more traction when wet, and it hides water spots and footprints.
Matte is non-reflective with the best everyday traction.
Same tile body and color, only the surface differs. Not every size is made in both finishes; a dashed size below is made in the other finish only.
Shower floor? Polished tile is slippery when wet, so it is not recommended for shower floors. For the shower floor, choose a matching mosaic.

Performance & ratings
What these ratings mean, in plain English
- Water absorption
- How much water the tile soaks up. Under 0.5% means almost none, which is why porcelain is safe in showers, outdoors and in freezing weather. Natural stone soaks up more, so it is sealed.
- Frost resistance
- Can it freeze without cracking? "Frost resistant" means yes, so it can go outside through a Kentucky winter.
- Slip resistance (DCOF)
- How grippy the surface is underfoot. Floors that get wet need 0.42 or more, measured wet. "Dry" means it was only rated for dry floors, so keep it to dry rooms and walls. The letters are the areas it is approved for: ID dry indoor floors, IW indoor floors that get wet, IW+ showers, steam rooms and pool decks, EW outdoor wet areas, O/G around oil and grease.
- Scratch hardness (MOHS)
- How hard the surface is on a 1 to 10 scale (10 is diamond). 5 or more shrugs off sand, grit and furniture legs; 7 or more is best for busy entries.
- PEI wear rating
- How well the glaze resists wearing through, 0 to 5. 1 and 2 are for walls, 3 is fine for any room in a home, 4 and 5 are for stores and heavy traffic.
- Breaking strength
- How much force a tile takes before it snaps. Floor tile needs at least 250 lbf; higher is tougher.
- Chemical and stain resistance
- How it stands up to cleaners and spills. Class A is the best (no mark left); Class B shows a faint mark only after the harshest chemicals.
- Thermal shock and crazing
- Pass means sudden hot-to-cold changes did not crack the glaze or leave hairline lines in it.
- Shade variation
- How much the pieces differ from one another. V1 all alike, V2 slight, V3 noticeable, V4 very different. Marble looks are usually V2 to V4, so pull tiles from several cases as you lay them.
- GREENGUARD
- Certified for low chemical emissions into indoor air, as listed by the manufacturer.
