Wood 1010 Wood and Finishing Technology: Sample Boards

In our 1st class back from winter break, we hit the ground running! The students have studied our 2 main text books, and we do some intense lecturing about solvents, coloring agents and coatings, as well as different means and methods of applying these things. Then we put this knowledge into action by finishing 10 different boards with 10 different finishing schedules.

We spray and brush lacquer, spray, brush and pad shellac, we brush varnish, we shoot gloss & satin, we do open pored finished, and closed pore "piano" finishes. We color strike pores, we stain, dye, glaze, distress, tone and shade. and we dabble a bit with water base finishes as well.

This intensive 3 week section is full of learning, and getting to experience what tools we have as finishers and what their benefits and challenges are.

Wood 1019 Spot Repair II: Jerry Behrens visits DCTC again to talk touch-up

Today we had our old friend Jerry Behrens back to talk touch-up work. You might remember Jerry from an older blog post, as he is a regular visitor to the program. Jerry graduated from NIWF in 1989, and has served on the board since 1992. He has also written, produced, and hosted two Wood Restoration Videos and has been gainfully employed in the field of wood finishing for 20 years.

Today Jerry was showing some of his techniques for doing spot repairs. Like I tell my students, if you see 10 different repair people doing a repair, you'll see 10 different ways to do the repair. So it's great to get some past grads in to show off their techniques, it exposes the students to a variety of solutions to a problem. Jerry was using colored graining pencils for one repair he demonstrated. He also shared some insight on color matching, working in the field, and did a large repair on a cupboard door.

Both repairs only took about 25 minutes and looked great when he was done; and he was able to pull them off while talking to students and answering questions. A big thanks once again to Jerry for sharing his time and talents with our students.

Wood 1015 Spot Repair I: French Padding Color

French Padding color onto a wooden object is part of Spot Repair. In these pictures you can see very worn wood, all the finish and much of the color has been worn away from years of use.






We can apply pigment to the wood, then use a French Padding technique to lock in the color.
















The end result, we have replaced color and replaced coating so our color is protected.

Wood 1012 Color Theory - Using New Mediums

Color Theory is the root of much of what we do. We can not repair a wooden object and hide that repair unless we can match the color of the wood and the coating on the wood. In color theory, we will make color wheels, and learn how colors relate to one another. We look at hue, value and chroma; and we learn how different mediums work differently.
In the first picture, you can see we are color matching, that is to say, the students are given a sample of wood and asked to find a mixture of colorants that will match. Currently we are using glazes to find that match, but in the near future, we will use powdered pigments, dyes as well as using different glazing and toning techniques to achieve a match.

In this second picture, we are discovering our powdered pigments. With these powders, we can mix them with a binder and carrier and make a paint. In this picture we are charting out what these colors look like on a white background so we can start to understand how they will behave when we start using them on wood.

Wood 1026 Advanced Finishing: working our color theory with dyes

"Learning is not attained by chance, it must be sought for with ardor and attended to with diligence."

-Abigail Adams

The color theory never leaves us, we just get the opportunity to apply it differently. We are in advanced finishing (Wood 1026) and we are, once again, matching colors, but this time we are using dyes instead of pigments. We are still using our color wheel and going about the process the same way to match the hue, value and chroma of the color, only the materials have changed. Exercises like this really solidify color theory and give us a greater understanding of the materials we are using.
