Abrasion resistance

A tile’s resistance to withstand surface wear is known as abrasion resistance. This surface wear is generally caused by repeated friction due to various daily elements, such as foot traffic and dirt. It results in loss of finish, dulling of texture and color, and other similar damage in both residential and commercial settings. It is closely associated with tile surface hardness and the durability of the glaze or top layer.

A tile may appear to be structurally intact; however, due to low abrasion resistance, significant surface damage may happen.

In simplest terms, the question ‘What is abrasion resistance?’ can be answered as to how well a tile keeps its original look with day-to-day use.

Surface Wear: Causes

Some common factors for tile abrasion are

Dirt

Different-sized dirt particles can act as sandpaper on tiles.

Pets

Running pets often damage tiles with their sharp claws.

Foot Traffic

Shoes that have a hard base or shoes carrying sand or grit.

Cleaning

Certain cleaning tools and chemicals may cause abrasion.

Furniture

Constant movement of furniture causes abrasion.

With time, these small actions can add up and may cause significant wear of the finish and surface of the tile. Matte finishes can help conceal minor abrasion, while glossy tiles highlight their smooth surface and reflective finish. While choosing flooring, tile surface hardness and overall wear resistance must be considered to ensure durability.

For porcelain and ceramic tiles with glazed surfaces, the abrasion resistance is measured using the Porcelain Enamel Institute (PEI) rating. The higher the PEI rating, the more resistant a tile is to foot traffic. Porcelain tiles generally have higher abrasion resistance, making them ideal for high-traffic spaces.
