Shop Conditions

Synthetics aren't as finicky as other finishes and can be applied in a wider range of conditions. The temperature in your shop should ideally be between 60 degrees F and 90 degrees F. Humidity should be about normal (between 45 to 65 percent). Ventilation is also very important and a good quality, high volume exhaust fan is highly recommended.

Dust control is really more important than any other shop condition -- since tacky synthetics are noted for attracting dust like a magnet. Though the shop should be well ventilated, open windows and doors should be avoided. Drafts from such openings can blow dust across the drying finish. Sweep the floors and machinery thoroughly and allow everything settle for a half hour or so before getting started. Sprinkle water on the floor to help keep the sawdust down, but be careful not to get and moisture on the project to be finished.

As for tools...like natural finishes, the appearance of a synthetic finish will improve dramatically if you use a good quality brush to apply it. However, you may be surprised to learn that you don't have to spend a lot of money to achieve a good synthetic finish. Many woodworkers have discovered that the disposable foam rubber brushes sold in most hardware stores and home centers for under a dollar work great with synthetic finishes.
