This technique uses a graining tool to create a 'false wood' finish.>
By Mac Simmons
This month, this column focuses on a faux finishing technique that I call "rolling out the grains." This faux bois (false wood) graining process is another "Old World" finishing technique that is still used today to produce false graining lines on various colored backgrounds.
It is easy to learn how to do this unique finish. As with most faux finishes, there are three basic steps. Step one is applying a colored base coat, which acts as the background color. The second step is using a colored glaze and a graining roller to add false grains on top of the colored background, and the third step is applying clear coats to protect these colorful finishes. This technique can be used in many different color combinations, both by changing the color of the background and the color used for the grain lines.
Starting the process
To be sure all your finishing materials are compatible, you should always make complete samples, from the start of the process to the last clear coat. This not only allows you to test all your materials for compatibility, but also to become familiar with the process. Select one of the color mediums for your background, apply the stain/toner/opaque coating to the sample, allow for complete drying, and then apply a seal coat.
Adding the grains
After you have perfected the application technique using the tool, you can change the background colors or use different colors for the grain lines to create unique looks.
If you look at the five samples in the photo above, you can see different types of effects that can be created by "rolling the grains" with different colors.
Saving some steps
You can get a feel for these step savers by trying them when you are making your samples. The key to grain rolling successfully is practice. Also, be sure not to overload the bristle or foam brushes you place on the graining tool. If you prefer brushing the colored stain or glazing medium on the rollers of the graining tool, then first test it on some newspapers to be sure you get uniform grain lines. Once you have the right amount of color on the rollers, you can start "rolling out the grains."
With a little trial and error, you can master this false wood technique.

I read your article on factory finishes in the March issue of CWB and would like to know if you can recommend a book to help me understand more about the process. I have a small cabinet shop and would like to know more, as I use a lot of different woods and have trouble getting them to look all the same.
I suggest that you go to your local public library and look up books by Bob Flexner, Michael Dresdner and Jeff Jewitt. You also can search the Internet to find their books on finishing. You can compare these books and see which ones fit your type of finishing.
I thoroughly enjoyed your article in the March issue of CWB. It was very informative.
I am a woodworker and stained glass artist and I build exterior doors. (You can see some of my work in the April issue of CWB.) I use Honduran mahogany in the construction of my doors. I try to hand-pick lumber that will match color and grain, but I'm not always successful. I am currently using the Sikkins product to finish my doors, because UV and humidity are a real problem here in Florida. My question to you is, would the steps you outlined in your article apply to exterior wood? Can I use toners and glazes as part of my finishing process? What effect will UV have on the toner and glaze layers?
Since I spend almost two months building my entryways, the finishing process is important to me.
You are actually in luck, because both the colored toners and glazes are made up from colored pigments. Pigments have an advantage over dyes because they are larger in size and they will block out UV rays much better than the smaller dyes. In fact, silica pigments are being used in some of the UV blockers for exterior coatings.
What you should do is make sure that your toners and glazes are compatible with your clear coats. As I always say in my articles, make up complete samples from the start of your finishing process to the final clear coating to be sure.
