4 Points Style White Matte Concrete Look Bullnose Porcelain Trim 4x12

4 Points Style White is a 4x12 matte porcelain bullnose trim piece shaped for the edges of a concrete-look surface. The white color gives the collection's industrial character a lighter expression, while the matte finish maintains a restrained, low-reflection appearance. This straight-cut trim is 9 mm, or 3/8 inch, thick.

Its 4x12 dimensions produce a long, narrow line that visually caps exposed edges and completes the ends of tiled runs. Compared with a smaller mosaic format, the extended rectangle keeps borders calm and linear. V3 shade variation introduces noticeable tonal movement among individual pieces, preventing the white concrete look from reading as completely flat. The variations remain part of the same color family while adding depth across a longer finished edge.

Absorption is limited to 0.5% or less, qualifying the piece as impervious porcelain that takes in almost no water. Breaking strength is at least 325 pounds, exceeding the ANSI floor-tile minimum of 250 pounds. The surface has a Mohs hardness of 7, a level that resists scratches caused by grit and sand. Class IV abrasion resistance is associated with busy residential floors and most commercial floors. Chemical resistance carries a Class A rating, while frost resistance and thermal shock resistance are both present.

This trim is sold individually, and each box contains 15 pieces with a total weight of 18 pounds. Other White formats in the line are 12x24 tile, 24x24 tile, and the 3 inch hexagon mosaic. Beige matte supplies another option in the same 4x12 bullnose format.
