PGVT means polished glazed vitrified tile. It starts as a GVT tile, but the factory applies a thicker glaze and then polishes it after firing to a mirror-like gloss.
GVT is usually sold with the finish it has when it leaves the kiln, such as matt, satin or a light gloss. Both share the same dense porcelain body. The difference is in the top layer, and that changes the look, the wear and the slip resistance.
How PGVT is made
The tile is pressed, glazed and printed in the same way as GVT. The factory then adds a thicker glaze layer, sometimes called a polishing glaze, so that there is enough material to grind and polish.
After firing, the tile passes through a polishing line. Rotating heads with abrasives of finer and finer grit smooth the glaze until it reflects light. The edges are often squared at the same stage. Read about that step in rectified vs non-rectified tiles.
How the two compare
- Look: PGVT has a high gloss and deep colour, which suits marble designs. GVT looks softer and more natural, which suits stone, concrete and wood looks.
- Slip: a polished surface is more slippery when wet. PGVT is usually not suited to bathrooms, entrances or outdoor areas. GVT matt finishes can reach higher slip ratings.
- Scratches: gloss shows fine scratches and dull paths sooner in busy areas. A matt GVT hides wear better.
- Stains: polishing can open tiny pores in the glaze. Factories often add a nano coating to close them, covered in nano-polished tiles.
- Cleaning: PGVT shows footprints and streaks; GVT matt shows grime in its texture. Each needs a different cleaning routine.
Where each one fits
PGVT is popular in living rooms, hotel lobbies, showrooms and offices with controlled, dry floors. Many buyers in the Gulf, Africa and South Asia choose it for a premium look.
GVT matt or satin suits kitchens, corridors, shops and anywhere the floor may get wet or carry grit from outside. For wet areas, check the slip rating. Our guide to slip resistance and R ratings explains the tests.
Many importers stock both in matching designs. A marble design can be offered in PGVT for the living area and in matt GVT for the bathroom, if the factory makes both from the same print.
What to check on samples
Polishing quality varies a lot. Hold a PGVT sample under a strong light at a low angle and look for these points:
- Waves or ripples in the reflection, which show uneven polishing.
- Pinholes or small pits in the glaze, which can trap dirt.
- Dull patches at the edges, where the polishing heads did not reach evenly.
- Gloss level that matches between tiles from different boxes.
Some factories state a gloss value measured with a gloss meter. If gloss matters to your customers, agree a target and a measuring method in writing, and keep a sealed reference sample.
