In a contract there may be reference to appearance grades, which applies to:

In the context of a contract, appearance grades specifically refer to the classification of wood materials based on the quality of their visible surfaces. These grades help determine the aesthetic quality of the wood when it is installed, meaning they assess characteristics such as grain, color, and the presence of flaws or imperfections that can impact the visual appeal of the finished product.

While the overall appearance of finished work is essential, the focus on appearance grades is directly aligned with the quality of visible surfaces. This is significant because various applications might require different grades based on how much of the material will be seen once installed, impacting decisions in selection and budgeting. Therefore, referencing appearance grades in the contract pertains primarily to the quality standards that apply to all surfaces that are observable after installation.
