Which tools are essential for applying medium-sized sheets of surface wood veneer by hand?

The use of a hard metal edge in conjunction with a short nap roller for contact cement is crucial when applying medium-sized sheets of surface wood veneer by hand. The hard metal edge helps create a smooth, even surface by providing a solid, straight edge against which the veneer can be pressed. This ensures that there are no air bubbles trapped underneath the veneer and that it adheres properly.

The short nap roller is specifically designed to evenly apply contact cement, allowing for a uniform layer that promotes good adhesion between the substrate and the veneer. The combination of these two tools is ideal for achieving a professional finish when working with larger sheets, as both techniques help avoid issues such as warping or uneven bonding.

In contrast, the other options either utilize inappropriate tools or techniques for this specific application. For instance, wood glue with a damp cloth and an iron is better suited for fabric or thin veneer applications, while a soft cloth and brush might not provide the necessary pressure and uniformity required to ensure proper adhesion of medium-sized sheets.
