Getting the most from your Lacquer Finishes

When & Why To Use
Flash-Off™ Control Solvent & Lacquer Blush Retarder

Use Lacquer Retarder
to avoid Blushing –

  Lacquer retarder is used to help eliminate “blushing”, the white foggy look caused
by HIGH humidity or rainy and cool/cold weather. This blush sometimes is only observed in areas where the build of the coating is thicker such as bull-nosed edges.
  Blush retarder keeps the finish wet longer allowing the trapped moisture to escape the coating. Another advantage is an even flow of the lacquer.

To Eliminate Orange Peel
& Over-Spray,
Use Flash-Off Control Solvent

  The Hot Weather Additive.

  Blush Retarder Is Overused.
In cases of orange peel or overspray,
Flash-Off Control Solvent is the best choice to solve the problem.Flash-Off Control is used to improve the flow of lacquers and lacquer sealers without slowing the overall drying time.
The addition of a few ounces of Flash-Off Solvent per gallon of lacquer will solve orange peel and overspray roughness.
Flash-Off Control Solvent will improve flow and yield overall film smoothness.



Flash-Off Control Solvent Use:
   Add 3 to 5 ounces, Flash-OFF per gallon,
to Mohawk air dry nitrocellulose,
pre-catalyzed and post-catalyzed lacquer coatings. More Flash-Off may be added,
up to10% by volume if needed, but that will increase dry time.

Do Not add Flash Off Control to water base lacquers or conversion varnishes.
(NOT for use with Shellac)

About Lacquer Thinners:
Avoid Overuse of Lacquer Thinner
   Most lacquers come ready to spray. This includes Pre & Post Catalyzed, Air Dry, Instrument & Piano lacquers. If the spray gun is set properly, add Lacquer Thinner only as absolutely necessary to achieve a proper spray pattern. Adding more thinner does not help the flow-out or drying time.

Control lacquer flow-out with Flash-Off Control Solvent. If blushing is the problem, use a small percentage of blush retarder.

   Lacquer solids generally are somewhere between 20% – 25% solids and formulated
to be, Air Quality VOC’s (volatile organic compounds / smog pre-cursers), compliant as labeled. Adding thinner will result in a
non-compliant coating. Excess thinner or reducer results in a thinner coat of finish,
thus requiring additional coats to achieve the required appearance and enough thickness to provide a protective coating.
