Using Varnish with a Spray Gun

Thank for taking time for my question.

I started a new business refinishing wood doors. When it comes to varnish, the directions on all the cans indicates to apply varnish with a brush. They do not have any information about using or not using a spray gun. I have been spraying the varnish on and it seems to be going on much more even and coming out much bettter after the doors are dry. I am using a .22mm nozzle.

Is there any problems with what I am doing? Will the varnish life be shorten by using this method?

Thanks for you help, Bill

Welcome to the forums Bill

As far as I know all varnishes/polys can be sprayed. Not all labels will give details about spraying. Unless you need to use a lot of thinner to make the varnish atomize there shouldn't be any negative effects from spraying - infact often spraying allows the application of a thicker paint film.

They put it in spray cans, so why not a sprayer. The problem with spraying any finish is the overspray, it settles on everything. A proper spray booth is best and technically is required by most EPA rules. The final results are nicer than brush or roller, but don't thin too much.
