Purdy identifies this type by the name “Parrot”; it’s green in color. This roller will hold a lot of shellac and can be messy to use unless you roll it in the tray to press out the excess. Start in the middle of the panel and work toward the edges. The shellac dries quickly, so distribute it quickly and evenly.

Uses of Plywood
Plywood is an engineered wood from the manufactured boards family which includes particle board and oriented strand board (OSB). It is made from thin sheets of veneer peeled from debarked wood. These thin layers, also called plies, are glued together in alternating right angles to create a cross-grain pattern.
Types of Ply
A ply refers to a layer of veneer used to create plywood’s various thicknesses. More ply creates a thicker and stronger board. Plywood has an odd number of plies and needs at least three plies. Although specialty plywood can have any number of plies above three, most plywood is categorized as 3-ply, 5-ply or multi-ply.
