    Welcome to week 2

    WALT: We are learning to test and record our functional testing results in our document.

    Task 1: Scratch test on various finishes.

    Task 2: Dent test on various materials MDF, Pine, Plywood, dowels etc.

    Scratch resistance

    The ability of a finish to resist damage from coarse or sharp objects is one of the most important qualities you’re likely concerned about.

    To a large extent you can know the comparative scratch resistance simply from the category of finish. For example, oil-based polyurethane varnish and catalyzed lacquers are much more scratch resistant than shellac and nitrocellulose lacquer, and usually a little more scratch resistant than acrylic and polyurethane water-based finishes.


    Task: Test the scratch resistance of various finishes.
