Woodworkers know how important accurate measurements are in building cabinets and furniture. A variance of just 1% in a 32” long board is 0.32”, more than a quarter of an inch, and will be readily visible to anyone if used. Some woodworkers set their saws up to be within 1/1000th of an inch. That might
Coatings technology has advanced rapidly over the last couple of decades. Two big reasons for the advances in durability, more environmentally friendly, and applications are the chemistries of the coatings and the finish systems that the individual coatings are a part of. Finish systems are specific coatings used together in a specific process to produce
Why do some finishes work together and some don’t? How many times has a poor choice of using finishes together resulted in a poor finish? Using finishes that weren’t designed to be used together can cause a multitude of problems. The best way to avoid these problems is to use finish systems as they were
Wiping stains are used on a great variety of woodwork. They can provide excellent color and a variety of aesthetics. The looks wiping stains provide have made them very popular. There are some problems that can be encountered when using wiping stains. Color “bleed,” which is the color coming back out of the wood to
Flat sheen coatings have become very popular, especially the dead flat coatings. What does flat or dead flat mean? Aren’t all the low sheen coatings the same? Does it really matter which one is used? These are all questions that have important answers that will determine the success of your low sheen finishing. Low sheen
Working within the shelf-life and pot-life of the coatings you use is vital to the success of the finish. Shelf-life is the amount of time after manufacture of the coating that it will be able to be applied and perform as advertised. Pot-life is the amount of time, after catalyzing, a coating will be able
The coatings temperature can be affected by the outside temperature in a couple of ways. Colder temperatures outside can mean cooler temperatures inside which means the coatings stored in the finish room are not as warm as in the warmer months unless a heater is used to warm the coating in line or in container.
The cold temperatures have made it to most of North America. The outside temperature can affect coatings in obvious ways and some that are not so obvious. Knowing how that can affect coatings is important to achieve a consistent finished product. Many finish shops are not completely climate controlled to provide a consistent finishing environment.
Waterborne finishes continue to become more popular. They allow for a lower health and environmental hazard. Also, the aesthetic qualities and durability have continued to improve over the years. This is so much so that often waterborne versions of a coating are more durable that their solvent based counterparts. We can see this in many
Polyurethane finishes are becoming commonly used by wood finishers. This tends to be based on those looking for more durable coatings to meet customers’ desires for not only good looking finishes, but very durable as well. Most two-component polyurethane (2K PU) coatings are more durable than catalyzed varnish. This is why many finishers looking for
