What is the name for a 4 inch by 14 inch piece of hardwood used to embed tiles on a flat plane?

The piece of hardwood described is known as a beating block, which is utilized primarily in tile installation. A beating block serves a crucial purpose during the tiling process; it provides a solid surface for installers to place their tools against when tapping down tiles. This ensures that the tiles are correctly embedded into the adhesive and set evenly on the flat plane.

The dimensions mentioned, 4 inches by 14 inches, are appropriate for a beating block, as this size allows for effective control and force application without risking damage to the tile itself. The hardwood material gives it the necessary sturdiness and weight, making it ideal for delivering precise blows to ensure proper tile placement.

In contrast, the other options serve different functions. A tile spreader is often used to apply thin-set mortar evenly rather than for the specific purpose of embedding tiles, while a backing board typically refers to a substrate layer on which tiles are installed, providing support and stability. A tile ruler is a measuring tool used to ensure accurate cutting and placement of tiles but does not directly engage in the embedding process.
