A sticker is a wooden strip or, its substitute, placed between courses of lumber in a pile at right angles to the long axis of the stock, to permit air to circulate between layers.

Stickers are strips placed perpendicularly between layers of stacked boards or flooring to improve air circulation. All lumber put into a kiln is “stickered” to promote uniform results by exposing every surface. Unfinished wood flooring should be “stickered” at the jobsite to arrive at equilibrium with the target environment of the occupied building. Straight Grain Also known as quartersawn, it is wood in which the direction and alignment of the wood fibers are parallel and run the length of the piece of wood.

When kiln or air-dryin wood, stickers are pieces of wood placed perpendicularly between layers of boards to allow for airflow through the stack. Stickers are usually placed 12 to 18 inches apart and directly over any support beams under the stack. Placing stickers as close as possible to the end of the boards helps to llimit end checking and reduce warp.

Strips placed between layers of lumber for drying.

The long narrow pieces of wood used between layers of piled lumber to allow for air circulation in the drying of lumber.

Narrow strips of wood placed at right angles between layers of lumber to facilitate air circulation in drying the lumber, either in a dry kiln or by air seasoning.
