Spray Finishing on Wood

A finish adds that necessary touch to any wood work, be it a interior window or a whole wall system. It is a job that requires a certain amount of skill but can certainly be done. There are different type of finishes and they all require their own method when it comes to applying them.

One of the most popular methods of applying a finish to wood is to spray it using mechanisms such as titan sprayers. The most common types of finishes are lacquer finishes, water-based finishes, and paint finishes. Here is how you can spray these different finishes on wood:

Lacquer Finish
Many industry experts endorse lacquer as one of the best finishes to use. Graco sprayers in Canada are quite popular for this job. Prior to spraying the finish, you should first apply a lacquer sealer. Once the sealing has set, you should gently rub at the surface with some fine sandpaper. You can then spray the first layer of lacquer. Nitrocellulose lacquer is typically the best finish to use as it is quite easy to spray. If you feel that the fluid needs to be thinned out, you can use a lacquer thinner. The first coat that you apply should be very light. This will allow it to dry faster. You can then gently create more layers, leaving at least a half an hour in between each coat. Once it has dried, you can gently sand the finish once more and apply a wet coat.

Water-based Finish
As with the lacquer finish, it is best to add a sealant to ensure a more even finish. You should note that the sealer will cause the end finish to look a little lighter than you may have intended it to. You can then begin spraying on your first layer. Keep the sprayer at a 90⁰ angle and hold it about six to eight inches away from the surface that you are spraying. It is always best to keep this layer quite thin. Water-based finishes should be applied in thin, even layers. Once the first layer has dried, you should sand it down until it is nice and smooth. You can then continue with the next coat.

Paint Finish
Prior to painting the wood, you should ensure that the surface is smooth and free of any old paint or other debris. If the wood is uneven or if there is a peeling coat of paint, you should apply a sealant before painting the wood. Once the sealant has dried, you can begin painting. Ideally, you should keep the sprayer about eight to twelve inches away when painting. The distance between the surface and the sprayer depends on the viscosity of the paint as well as the pressure of the sprayer. If you are planning on using more than one colour, first allow the initial hue to dry first before applying another one.

It is important to start on even, clean surfaces regardless of the finish that you are using. This will allow you to obtain a more even, professional look. You should also use a sealer that is appropriate to the finish that is being used. You should always use the highest quality in both finishes as well as sprayers for this job.
