Color Matching, - Color Blending

30. June 2016 11:40

By: Mitch Kohanek

Recently, I was in need of a color match on a 30 year old opaque exterior color.  It was for a few new pieces of Masonite siding I replaced on my house.  “Back in the day” that meant going to your local paint store in hopes of finding someone who had the knowledge and talent to mix colors by eye.

With today’s technology, a spectrophotometer made short work of matching an exact color for me. Gave the store a piece of the old siding, they made me a quart of paint that was a spot on color match of my old existing siding.

For transparent and translucent wood coloring using dyes, stains, micro pigments the meter comes close, but it can’t be relied on to be as accurate as it is with opaque colors. It can be a valuable tool, it has its benefits, but in many cases the color often needs to be adjusted “by eye”.

1.    The various natural shades of species of wood like white oak.
2.    The natural colors of cherry, walnut, and mahogany.
3.    Red oak and white oak in the same pile of oak that is to be used
4.    Blending Sapwood to Heartwood
5.    Quarter sawn glued next to flatsawn
6.    Veneer next to solid stock wood
7.    New wood that needs to look like old wood colors.
8.    Refinishers who need to strip and sand down an old table top and refinish the top to look like the sides of the cabinet.
9.    What degree of translucency you are looking for.

Because of all those variables color matching is back to being accomplished “by eye”. Whether you are creating color or correcting the color, it is critical for the finisher to be in command of color knowledge.

Basically we only have two main choices of coloring agents, one which contains pigment, which I refer to as stain. Paint falls into the pigmented category. The other coloring agent is a dye, which I categorize as having no pigment. There is a third medium, the chemical coloring of wood sometimes referred to as “reactive” stains or mordants. They do not contain pigments, they are more similar to dyes.  When applied to wood they “react” to the chemistry inside the wood, such as the tannins.  Mordants are often applied before dyes are applied to achieve colors not found any other way. For now, let’s stick with the dyes and stains for understanding color.

Dyes and stains (pigments) are two different tools. Used individually they offer two different visual presentations. Used together they greatly expand the color pallet. There are manufactures that formulate their dyes and stains so they are able to be mixed together. Mixing them together can offer a one-step coloring schedule rather than two.

Approaches to mixing colors
1.    Start with a clear base medium and use stains (pigments) using the primary colors, yellow, red and blue with the addition of white and black.
2.    Start with a clear base medium and use stains (pigments) using yellow, red, black and white
3.    Use premixed colored stains. An example would be using the earth tone colors, Raw Sienna, Burnt Sienna, Burnt Umber, Raw Umber plus black and white.
4.    Use the premixed colored stains plus the primary and/or secondary colors.
5.    Dyes are sold in liquid and powder form.  Decide on using the primary colors or pre-mixed colors such as the earth tones, or use them both.

I teach a systematic approach to using any color system and it all starts with the artists’ terms of hue, chroma, value, shade and tint. When looking at a target color, the first thing to do is identify the hue. Next would be identifying the chroma and then the value of the color. If you understand color theory it does not matter which system of dyes or stains you use.

One reason to start with the earth tones or other similar colors is that hopefully one of them comes close to the target color. Choosing the first earth tone is your base color, your second choice is determined on if you need to “warm up” or “cool off” the first color. It’s not guess work, it’s an educated choice.

Many shades of making “brown” in a one-step application can be made with just one umber and one sienna. Adding a third earth tone color is not unusual. Three well-chosen earth tone colors and the proper proportions of black, white or clear base if needed produces a tremendous amount of colors.

Some finishers would rather work with fewer colors and a clear base. These finishers think of color in “parts”. Example: 100 parts yellow, 10 parts red, 5 parts black is a color. To “tweak” that color is to first understand color and keep track of your “parts”. The results are going to be the same with both systems as long as you understand color theory.

It’s worth mentioning that if you choose to use pre-mixed colors like the earth tones, having the primary colors handy is another valuable addition. An example would be knowing that red needs to be added to your mix.  Burnt Sienna is an orange Hue and is the closest color you have to red.

If the target color can’t be accomplished in a one application step, it will have to involve a color on color finishing schedule. Color knowledge just got more important. A multi-step coloring schedule could involve a dozen or more finishing procedures for a completed color. Those tools for creating color are in the form of dyes, stains, glazes, toners and paint.

I will address those tools in the next blog.


Spot Repair - Level of Damage: Level of Skill

30. June 2016 11:36

By: Mitch Kohanek

“Spot repairing” wood brings to mind so many variations after so many years of repairing damaged objects. Damage to white wood, damage to newly finished wood, damage to just the coating, damage to the finished wood and coating, restoration of old wood and the heritage antiques worked on during my internship at the Smithsonian Museum.

Different levels of damage require different levels of skill.

Repairs happening in the shop where the customer has not seen the damage is a comfortable place to be. Repairs being worked on outside the shop can really be challenging, having fewer repair tools and working on damage that has probably already been seen by the owner.

The first tools needed in either category is your level of talent, creativity and knowledge of your materials. Repairing in house in a manufacturing environment the repair system can be rather straight forward.  If you ask 10 “Road Warrior” repair technicians (those who do repairing at the site of location) how to repair any given damage, you will get a variety different answers.

One example of damage is one that penetrates both the coating and the wood. The repair kit needs to first include something to refill the void in the wood. The higher skill level is associated with the coloring on top of that fill.
There are a host of materials that will fill the void. The size of the damage and the location of the damage will dictate which one of those is a better choice. Soft wax fill sticks, hard wax fill sticks, hard plastic fill sticks, low sheen sticks, high sheen sticks, shellac sticks, polyester fills, epoxy sticks and wood putty to name a few.

Sometimes a “burn in” is required which means the repair stick has to be heated with a hot knife and dropped into place. There are several choices of heating knives to choose from. There are two very different burn in “systems” we will be discussing, each requiring two different skill levels.

All of these sticks come in a variety of colors to correspond to the existing color of the object. The more you know about color matching and performing in-painting (graining), the fewer colored sticks needed. One of the more valuable fill sticks is one that is totally transparent. Excellent stick for dents in the wood and the coating has flexed with the wood with no color loss.

Once the void is filled, the excess needs to be removed and the surface leveled without causing any more damage to the coating or substrate. Don’t forget about the reestablishing the earlywood pores with an open pored finish.
The fill stick now needs the proper protective coating applied on top of it. Padding, brushing and spraying are your options for coating application. Solvent and waterbase coating are your two choices. Compatibility of the repair products and coating should be taken into consideration.

Once the void is filled, leveled and sealed the real “artistry” begins with the in-painting (graining) and creating a faux finish on the repair. The goal is to recreate the color, grain pattern and texture that used to be there.
Depending on the size, shape and location of the in-painting there are different tools to choose from. Touch up markers and graining pens are handy and do not require very much skill. Hopefully you have the right colors and ones that work.

Highly skilled repair technicians rely on pigments and/or dyes for coloring/graining/in-painting using a variety of different sized brushes. Doesn’t matter if it is a transparent, translucent or opaque finish that you are working on. Color is color. The more you know about color, the fewer colored pigments and dyes you need. Plus the fewer colored repair sticks you need.

Color matching is a challenging art. Sheen control can sometimes outweigh the stress of finding color. Off the gun low sheen finishes are a real challenge. Sheen has its nomenclature such as gloss, semi-gloss, satin, flat, dead flat. More accurately sheens are given numbers such as 80 degree sheen (high sheen), 50 degree sheen, 20 degree sheen, 10 degree sheen (low sheen), etc.

It is convenient to have aerosol cans that are labeled with the sheen number they produce. For mechanical sheen control adjustments, steel wool and synthetic steel wool (abrasive pads) have certain grits and sheens associated to what they will produce. A rubbed out satin sheen does not look much like a sprayed on satin sheen.

In order for damage to “disappear” all of these steps need to be executed to its highest degree. In reality making all repairs “disappear” is not reality. With so many variables you need to recognize what actually can be accomplished. The greater the damage, the greater the skill needed.

All of you who have walked this road know that WE are OUR worst critics when it comes to knowing when to quit working on the repair. Some go buy the 6” by 6’ rule.
What I have learned is that when that little voice in the back of your head says “Just one more grain line, just one more bit of color”………. Ignore that little voice.

Social Media & the Forest Products Industry: Reasons for Adoption and Metrics for Success

16. June 2016 07:36

By: Iris Montague, Research Forester: USDA Forest Service; Kathryn Arano, Associate Professor of Forest Resources Management: West Virginia University and Jan Wiedenbeck, Team Leader/Research Forest Products Technologist: USDA Forest Service

In 2013, we investigated social media use by companies in the forest products industry in the U.S. We received information from 166 companies.  About 60% were using some form of social media as part of their marketing mix and most of these companies (90%) had started using social media recently (since 2008).  We learned from these companies that Facebook was the most used social media site, followed by LinkedIn.

The majority (63%) of the companies that were using social media have a person who is dedicated to social media development, yet responses indicated that on average their social media sites only get updated on a monthly basis or less. Research shows that message frequency (the number of times an average person or household is exposed to a company or brand’s message) is very important in achieving consumer recall and attitude change and maintaining fresh content on company social media sites is considered a key to being successful at engaging current and potential customers (Kaplan and Haenlein 2010).

The top three reasons cited by companies for using social media were (1) to increase exposure, (2) to establish branding, and (3) to improve sales. Although the benefits of social media use are well documented, there are still many who are apprehensive about using it.  Generating a return on investment (ROI) to cover costs, generating member/customer activity, having staff to manage social media sites, getting members or fans, and maintaining site security were identified as challenges of adopting social media.

Because the nature of social media as a marketing tool makes calculation of ROI challenging, forest products companies mostly focus on other quantitative metrics (non-dollar) as well as on qualitative metrics for measuring the effectiveness of social media. The top three quantitative metrics used for evaluating social media effectiveness were: (1) number of site visits, (2) number of social network friends, and (3) number of comments/profile views. In terms of qualitative metrics used by companies to measure social media effectiveness, the three most commonly used metrics were: (1) growth of relationships with key audiences, (2) audience participation, and 3) moving from monologue to dialogue with consumers. From a marketing standpoint, focusing on these metrics rather than just ROI may be a good social media strategy.

Are Mushrooms the Solution to the Industry’s Petroleum & Chemical-based Resin Challenge?

9. June 2016 06:53

n     Growing Interest in the Industries New, Natural Resin

Could mushroom materials be the solution to the industry challenge of formaldehyde and other toxic resins used in the production of engineered wood? 

That was the question posed by furniture industry executives to our co-founders at Ecovative a few years ago.  It may sound like an odd question to some, but as the pioneer and world leader in mycelium-based biomaterials and, given that we use biology to grow materials with exceptional properties unattainable through conventional chemistry, the question made perfect sense for us to explore.

Flash forward two years, and the answer is “yes,” and the solution is MycoBoard™ a premium, customizable, certified sustainable engineered wood product. It is bound together using mycelium—“nature’s glue”—which is formaldehyde-free, safe, and healthy. This versatile, non-toxic engineered wood, which offers natural fire-resistant properties, can be molded into custom shapes or pressed into boards, making it an ideal solution for the architectural and design community.

You will find MycoBoard™ in an award winning chair, in commercial wall panels, and in other products being produced by leading furniture manufacturers and designers.

MycoBoard™ provides a solution to the rising cost of resins, the growing customer concerns about product health and safety, and looming possibility of expanded government regulations.


Interested in talking about how to integrate this new bio-resin into your product planning and production?  Join us at the “Wood Composites Symposium,” on Tuesday, August 23rd.  In session one (8:30 a.m.) we will be talking about “Resins and Coatings for Wood Composites” – including Ecovative’s bio-based resins—for composite panels and structural members.


3 Axis Nested Based CNC-What Else Can I Do With It?

8. June 2016 09:17
So you have purchased your first CNC Router! The jobs are flowing thru the shop at a pace that you could have only dreamed of and you are becoming more comfortable with the machine and the programing. Now you start to dream about the possibilities and doors that are opening up if you could make other items with all of the excess capacity that is available for your CNC. This is precisely the vision that I had for my CNC router 8 years ago when I purchased my first router.
For the first year or so we produced just our cabinet parts via Cabinet Vision we would occasionally cut curved bottom rails or lambs Tongue feet for vanities and the like. Along the way we learned about fixturing methods for flat table CNC routers.

We then took on a project that would require elliptical casings, Keystone with center carvings and a two story tall great room with spoon gouged rift oak panels and large detailed crown with applied rafter tail ends. This required additional software with which we would be able to produce complex 3-D shapes and geometries. We used Vetric V-Carve Pro for the spoon gouge texturing and Bob Cad Cam for the true 3-D carvings and elliptical moldings. Both packages were fairly easy to learn and we were producing code within a couple of weeks. With these software packages you had to understand more about 3-D drawing and layering as well as proper tooling and tool path strategies.


As we developed all of these skills we were able to diversify our products and offerings to our customers which in turn bought additional work into our shop and allowed us to bid on jobs we would have passed on prior to having the CNC in our shop. We were also able to produce just CNC parts for other companies and individuals. We have turned the machining of cabinet parts and components into its own business that we market separately from the cabinet business with great success and profit.

In closing I have found with few exceptions that we are able to produce just about anything we or our customers can dream of. You will need to put in time to research the proper software and tooling to produce the product need and learn about different fixturing techniques, tooling types and tool path strategies. If you do all of this you will put your investment of time and money to work for you and your company in ways you had not imagined.

You can learn more about the discussion above this summer at IWF in Atlanta myself and David Bushsbaum will be presenting for IWF Education Conference on Wednesday August 24th from 3-4pm CNC Tips And Tricks

Wood Flooring Benefits & Expectations

31. May 2016 08:04


Ask any wood flooring inspector about his or her experience analyzing wood flooring failures, and many will tell you that a good number of them are not due to manufacturing issues or installation errors.  Surprisingly, many happen at the point of sale, with the flooring retailer selling the wrong product for the job.


Fortunately, this issue is easily preventable with a little training and knowledge about how wood flooring will perform in different environments.  Preparing sales teams with the proper understanding of how wood flooring products differ can help them educate customers and create realistic expectations about the long-term performance of their floors.


Grading is one such issue.  Wood flooring is graded according to its appearance, which includes things like grain, texture, mineral deposits, and knots.  When customers understand that wood is a product of nature, and that no two pieces of wood flooring will be identical, even two pieces from the same tree, they will have more realistic expectations about using wood as a flooring material. 


Likewise, it is important to dispel the myths about wood flooring being bad for the environment.  Wood is the only flooring material that is entirely sustainable because trees are a natural resource that can be regrown.  Wood grows in a factory called a forest using a renewable source of energy called the sun.  Manufacturing wood into flooring also uses less water and energy than manufacturing other flooring materials, which makes wood an environmentally friendly flooring option.  Wood also is carbon neutral.  During their growth cycle, trees produce oxygen.  What most people don’t realize, however, is that during its service life, wood also sequesters carbon.  So whatever its end use – as flooring, cabinets, even picture frames – wood continues to sequester carbon during its entire service life.


Helping consumers understand the many environmental benefits of wood flooring can lead them to choosing more wood for their flooring projects, while helping them to understand grade and performance issues can help establish realistic expectations that will result in happy customers and increased sales.


These and other issues will be presented at the IWF Wood Flooring Symposium on Tuesday, August 23 from 1:30pm – 4:40pm by the National Wood Flooring Association’s VP of Education & Certification, Brett Miller.  The NWFA also provides a number of workshops in addition to detailed guidelines about issues relating to wood floors.  For more information, contact the NWFA at 800.422.4556 (USA and Canada), 636.519.9663 (international), or at www.nwfa.org.
