Getting the most from your Lacquer Finishes
When & Why To Use
Flash-Off™ Control Solvent & Lacquer Blush Retarder

Lacquer Retarder helps avoid Blushing  caused by Cold Humid Wet Weather
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.
Generally,
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.

L
acquer 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.

STOP throwing away partially used oil paints and varnishes
Use Bloxygen

Bloxygen uses ultra pure Argon, the  natural inert gas
drives the oxygen and moisture from the container.
Simply blow the oxygen out of the container with Bloxygen,
then seal the lid.
The heavy, inert Bloxygen gas sinks down and blocks oxygen
from the liquid surface. Because Bloxygen is heavier than air,
it will seal the liquid from any air that may remain in the container.

• Recommended for oil / solvent based products.
• Up to 75 uses per aerosol. • NOT for use with latex or lacquer products.
• Non-flammable  • Non-toxic   • Contains argon

Is BLOXYGEN expensive?   It Is Not, BLOXYGEN lasts for about 75 uses for quarts.
At $9.95, BLOXYGEN only costs 13 cents per use.
If you save just one half  of a $20 quart of varnish,
you’ve paid for your BLOXYGEN. The next 74 uses are “free!”

Lighting for Wood Finishing

Proper use of Light will Improve your Finish

& enable you to really SEE what you are looking at.

Lighting for shop work and finish room areas, and its correct use,
is important for obtaining high quality good looking finishes.

Lighting and Color

With translucent & clear furniture finishes light travels through all the finish layers and is reflected off the wood or substrate. The ‘Observed Finish Color’ is a combination of all the color tones in the various finish stain & dye layers combined with the wood color.

Finish Diagram of Clear or Translucent Furniture Finishes
Light travels through all the finish layers.
The Finish color is a combination of all
the colors in the various finish layers
combined with the wood color.

When studying a color we notice that its hue will vary depending on illumination and its surroundings. Illumination changes the color hue of an object due to the color available in the light source. Color is the product of wavelengths that are either absorbed or reflected by the surface of an object.
see: Color Theory and color mixing for the woodworker.

The hue appears to alter according to a colors surroundings. Our retina is affected by these wavelengths and the stimuli are communicated to the cortex, that part of the brain that enables us to distinguish one shade from another.

Light bulbs are available in:
1 – Warm white or soft white (2700-3600 °K)
2 – Cool white (3800 -4800°K )
3 – Daylight or Full Spectrum designations (5000°K) or higher.
The color spectrum output of a bulb is rated in Kelvin° color temperature (has nothing to do with the heat a bulb produces). Full Spectrum Daylight bulbs for incandescent and compact or linear fluorescent are available in a range of wattages and styles.

You need the entire color spectrum in your light source to evaluate or match stain and finish colors accurately. Full Spectrum Daylight Bulbs with a high CRI (color rendering index) are a must. Better daylight bulbs will list the CRI on the package, the higher the number the better. A CRI above 85 is good for shop use. Bulbs rated above 95 are expensive and are not needed for wood finishing.

The very best light for critical color matching work is natural daylight (out of direct sun glare).

SEE what you look at !

Proper use of lighting will automatically improve your finish quality.
When you can really see what is happening the finishing process is easier.

Now you have the right light to see color – Correct use will enable critical evaluation of the surface condition prior and during the finishing process.

Fluorescent lighting (Cool White or Daylight bulbs only) is fine for ambient lighting or general work area illumination. Avoid using warm white or soft white bulbs they bathe everything in a yellowish light. The shadow-less lighting produced by fluorescent bulbs tends to hide surface defects.

Inspection Lighting:

A shadow producing light source is necessary to see that a surface is free of any unwanted defects.

Use incandescent bulbs in a reflector for inspection lighting in:
1, surface prep areas (sanding, dying staining)
2, finishing areas
3, final rub-out, waxing or polishing.

Arrange inspection lighting so that the light is aimed at the work and toward the operator so that any defect is accentuated by the shadow or reflection it produces. When you can easily see: scratches from sanding, glue smears, minor dents, brush marks, finish drips, runs, curtains or sags, and polishing or rub out marks it will be much easier to achieve the desired, defect free, finish look.
