Fuji Spray | Myth vs Reality - Waterborne Finishes
When it comes to waterborne finishes, there’s so much information floating about that it’s hard to know what is a myth and what’s reality. Read our helpful blog and explore the common myths and half-truths about waterborne finishes!
Myth #1: Waterborne finishing materials can be sprayed without wearing a mask
This statement is completely false! Waterborne finishes have significantly less Volatile Organic Compounds, otherwise known as VOCs, as well as Hazardous Air Pollutants (HAPS) than solvent-based counterparts. However, despite this, we always recommend that you wear a protective mask to safeguard your lungs at all times.
Myth #2: Waterborne finishes aren't as good as solvent-based finishes
Once again, this is false. Far more elastic than solvent-based counterparts, waterborne finishes are ideal for woodworkers. They dry faster which allows you to finish projects more quickly. What's more, they are nearly as durable as solvent-based finishes, and they are also non-flammable for complete peace of mind. They are so versatile, all major flooring and car manufacturers have switched over to these type of finishes. Enough said?
Myth #3: Waterborne finishes are difficult to apply
This is also a false statement. Modern waterborne finishes are just as easy to apply as solvent-based finishes. Over the years, there's been lots of investment in developing such finishes to the standards they are today. Of course, there's some basic instructions you need to follow to ensure a smooth application. These include straining your waterborne finishes, respecting the humidity and temperature ranges as well as paying close attention to proper cleaning straight after use. Finally, you must always ensure you apply the finish as per the manufacturer's recommendations.
Myth #4: Waterborne finishes need to be thinned to spray
Next, this statement is also false! Using a High Volume Low Pressure (HVLP) spray system, there's no need to thin waterborne finishes. This applies to finishes including lacquer, sanding sealer, polyurethane, conversion varnish, stain and dye, and more!
Higher viscosity, thicker finishes such as latex paint or pigmented lacquer often require some thinning. However, not enough to affect the finish quality. In all cases, best results can be achieved by mating the recommended air cap to the product being sprayed.
Myth #5: Waterborne finishes cannot be applied over solvent-based finishes
Finally, this statement is also not true. So long as the finish has been left drying for at least 18 hours and wiped by a clean, lint-free cloth dampened with a solution of water and denatured alcohol mixed 1:1, you should not encounter issues. That said, it is always recommended to test in a small, concealed area, such as the underside of a chair or table.
