Building An Industrial Wood Finish

The information contained in this manual has been gleaned from the experiences of the author collected during more than 30 years as a supplier of wood finishes to manufacturers of finished wood products and as a consultant to the industry. The purpose of the manual is to help manufacturers gain a full understanding of all of the factors that impact the quality, durability, cost, and environmental impact of finished wood products. Four chapters cover: Finishing Products – multiple-step wood furniture finishes, kitchen cabinet and office furniture finishes, specialty wood finishes, and waterborne/water-based finishes; Executing the Wood Finish – wood finish application hardware options, examples of wood finishing manufacturing lines, and transfer efficiency and calculation of wood finish costs; Wood Finishes and the Environment – legal and regulatory issues and pollution prevention opportunities through hardware and finish product improvements; and Quality Control – white room wood preparation, wood finish variables and recommendations, finish inconsistencies/troubleshooting, the importance of lighting, and analyzing rejected pieces.
