What Is a Tile Radius Cap?

Description

• The rounded lip of a radius cap is set at a 90-degree angle that continues around the edge of the tile, instead of leaving the edge exposed. This is only necessary if the tile set is not flush with the surrounding wall. Radius caps are just like normal tile and are made of exactly the same materials, except that they have a ceramic edge to hide transitions. Tile radius caps are available in various color and style options. They are often available for purchase in conjunction with a tile set.

Selection

• An ideal tile radius cap is made by the same manufacturer as the tile set so it can be coordinated with your main tile installation. Generally, these caps consist of a glazed ceramic finish as with most tile sets. Some caps are made specifically for indoor installations, such as bathrooms and kitchens. Others are designed for outdoor use and can be applied to pools and patios. There is also special bullnose radius tile designed for corners, with two rounded edges.

Installation

• Keep your radius cap in mind when planning your overall tile layout. Use bullnose tiles or radius caps whenever an edge of tile is exposed. If necessary, you can grind down the edge of the tile to fit it as needed. When installing the cap, apply grout at the same consistency as the rest of the tile. Set the cap in place and use a level to make sure it is straight. Use a warm, low-alkaline, diluted detergent for cleaning the tile.

Trim Tiles

• Radius trim is appropriate whenever the tile is above the surrounding surface, but if the tile is flush with the wall, use surface trim. If you cannot find trim that is compatible with your existing tile, you can round the edges of a tile piece yourself, or use PVC or other material to construct it. While trim tiles are important for aesthetics, there are many options to choose from. One option is to select trim with special molding, for an elegant look. Another option is to use trim of a different color or consistency to serve as an accent for your tile.
