There are three methods to choose from for
application:
Wet-on-Wet Method
Apply the first coat normally, and
when dry to the touch with no stickiness (approximately 1 to 2
hours), apply the second or next coat without sanding. You may
recoat without sanding at any time up to 24 hours after the last
coat was applied.
Dry Method
Apply a coat, allow to dry completely, sand and repeat.
Why anyone would want to do this we don't know, but people ask all
the time. By using this method you lose at least half of the
benefits of using Bristol Finish. Note that when
sanding between coats, you must apply 12 coats to end up with 6
coats on the surface of the high spots.
Practical
Method
(for a 6 coat application)
Apply 5 coats in one or two days using the Wet-on-Wet method
described above (maximum of 24 hours between coats). Don't
stop because of runs, drips or small amounts of dust. Allow to
dry for a day or two, and sand using 220 grit paper until smooth and
uniformly dull. Use a 3M #7447 red ScotchBrite pad on sharp
corners and edges. Lightly wipe with acetone or lacquer
thinner and follow with a tack rag to remove dust Apply 2
final coats without sanding in between This method gives you a
very fast, easy buildup and the chance to take out any defects with
a minimum of labor. Note that when sanding between coats, one
extra coat must be applied for each sanding session, so that there
is a minimum of six coats on the surface.
For either method, lay the coating on with the
brush, and tip back once in the opposite direction. Do not
excessively work the brush back and forth.
For roller
application, use a roller to quickly spread the coating on a 2' x 2'
or so area, and tip once with a slightly wet brush. This
technique will require practice (or 2 persons) if you are not an
experienced painter.
Spray application should be performed only by
qualified professional operators that are familiar with 2 part paint
systems.

Using the Satin Additive
The use of our Satin Additive is
very easy and straightforward. Packaged as a separate
component, the Satin Additive may be used in small amounts for a
light satin effect, or in larger amounts for a completely flat
finish, or anything in between. The Satin Additive comes with
complete directions for mixing and use.
When a satin or flat appearance is desired, we
advise that all buildup coats be applied by using the normal high
gloss product, and then the final coat is applied with the Satin
Additive mixed in.
Cure Times
Bristol Finish does not have maximum strength or
solvent resistance until fully cured. Allow a minimum of 48
hours before re-assembly of hardware or hard service when
temperatures are above 70 degrees F. More time will be
required in colder temperatures, or when working indoors with
inadequate ventilation.
General Considerations
Achieving a
beautiful brightwork job requires good, basic painting skills.
This is not a requirement that is particular to
Bristol Finish
, but to every varnish or paint product known to
man. Improperly sized (too small for the work piece) brushes,
overbrushing or losing the wet edge will guarantee bad looking
results. Our favorite technique description is nice and
simple- lay the coating on, and use a maximum of 3 brush
strokes. 1 stroke to apply the coating, 1 to spread it out,
and the final stroke to tip off the brush marks. Always make
your final stroke back into the wet area, and reduce the pressure as
you move along, just like an airplane taking off. Use the
largest brush that will fit the work piece. Always make the final
stroke back into the wet area, with decreasing pressure.
This is not a new technique- we found this in the
1879 edition of VanNostrands. It is still true
today.
