Spraying TotalBoat Lust varnish with a non-skid additive mixed in is effectively the same as spraying a one-part paint with non-skid. Proper reduction and having the proper tip size on the spray gun are even more crucial when spraying a non-skid finish.
A wider tip is required on the gun, but it must be one that is wide enough for the non-skid media to go through, but not so wide that it spatters and lacks control. This will be completely dependent on the size of the non-skid media. Next, the varnish must be properly thinned. The spray reducer for TotalBoat Lust is xylene (Xylol). If xylene is not readily available, Interlux 216 or Pettit 121 spray thinners will work as a quick substitute. The amount of spray reducer needed is dependent on the spray gun, environmental conditions, and the right sense of 'feel' for the person spraying. Because of the solvents concentration required for spraying, it is encouraged to wait longer between coats to ensure the best cure and results.
Possibly the most important thing to remember when spraying non-skid is that the wider tip will dispense more varnish at a time. It is extremely important to not apply too much TotalBoat Lust. Thin, even coats are crucial for proper cure. If there is too much reducer, the varnish can sag, or it will slow the cure down. If too much material is applied, it will form a cured skin on the surface, but stay soft and liquid underneath due to the high concentration of drying agents in Lust varnish. If this occurs, there are two options: the best course of action is to wait until it cures to a hard finish and does not feel soft under, which may take days, or you can try to remove the coating with a scraper and solvent, then start over.
