3 Lots of Challenging Issues for Finishing No Agreement on What is a Good Finish Finishing is as Much Art as Science You Really Must do the Hands-on Work and Figure Things Out for Yourself Finishing Materials Do Change Over Time

4 Quick Introduction to Color Theory Color Theory Goes Back to Sir Isaac Newton (Prisms) = Light is the Source of All Colors Color is a Product of Light Wavelengths Absorbed or Reflected Colors on Wood Products Are Additive -Wood + Stain + Glazes + Top Coats + Pad Stain + Consult Handout for Additional Information

5 The Color Wheel 7 Principal Colors- Red, Orange, Yellow, Blue, Indigo, Violet Primary Colors = Red, Yellow, Blue

6 Color Terms-See Handout Hue Color Value Chroma Primary Colors Secondary Colors Intermediary Colors Tertiary Colors Complimentary Colors Warm Colors Cool Colors

10 Managing the Finishing Operation for Profit $ Finishing Affects the Cost of Products Finishing Affects the Throughput of a Shop or Factory Finishing Bottlenecks and Problems Can Kill a Company Good Finishing May Be the Cause of Success

11 Account Size Affects the Vendor Selection Options for Commercial Operations Large Purchases = Lots of Attention Splitting the Finishing Account May Lead to Less Attention Account Size and the Nature of the Business Affects the Economics of Finishing Material Cost (Tankers Vs. Drums Vs. 5 Gallon Pails Vs. Gallons)

12 Cookbook Color Systems The Supplier Creates Formulas Based on Weights Samples Show User What Formulas Will Create A Wonderful Way to Obtain Repeatable Results Great for Employees New to Finishing Reduces the Cost to Create New Finishes

13 Example-Sherwin-Williams Stainware System User Stocks a Limited Number of Base Materials Stainware Program Has Photos of Example Finishes Each Finish Has a Formula Based on Weight User Has a Digital Electronic Scale Formula is Scaled Up to the Volume Required We can utilize this concept for Green finishes too!

14 Recordkeeping and Quality Control for Colors It is Critical to Record Every Finish Created for a Job Good Records Supports a Good Quality Control Program Measure With Scales and Graduated Cylinders Use Number Codes for Finishes Limit the Number of Vendors Who Supply Your Finish

15 Understanding Finishing Economics Two Ways to Understand Finishing Economics: Standard Cost Method-Where One Estimates $ of Finishing Materials + Supplies + Labor Cost + Overhead Share = Cost of Finishing Bottleneck Method-Considers How Finishing Affects Income Statement Revenues and Expenses See Handout

17 Supporting the Finishing Operation Front Office Bosses Should Not Run the Finishing Dept. Finishing Should Be Balanced in Working Hours With the Rest of the Shop or Factory A Cookbook Color System Is a Good Idea-Cuts Time to Make Finishes and Has Better Chances of Repeating Correct Colors Green Finishes Can Be Cheaper Than Petroleum Finishes
