Preparation Tips - Black & Decker BDPH200B Instruction Manual

Warning! Be sure to use appropriate protective gear
and unplug unit.
Warning! Make sure area is well ventilated and free of
flammable vapors.
Aligning the pickup tube (FIG B and B1)
The pickup tube can be aligned in the direction that you
will be doing the most spraying to help minimize the
amount of times that you will have to refill the canister.
f If you are spraying at an upward angle or straight on,
position the pickup tube (Figure B) toward the back
of the canister.
f If you are spraying at a downward angle, position
the pickup tube (Figure B1) toward the front of the
canister.
This will ensure you spray as much material as possible
before you need to refill.
Liquid material preparation (FIG C, C1 and C2)
Tip: Make sure the type of material you use can be
cleaned with either mineral spirits or paint thinner (for oil-
based paints) or a warm water and soap solution (for water
soluble paints like latex). Use drop cloths during pouring,
mixing, and viscosity testing of materials to be sprayed to
protect your floors and anything else in the spraying area
that you wish to remain untouched.
The liquid being sprayed may need to be thinned (diluted)
before starting. When thinning, use the proper liquid
thinner recommended on the container by the material
manufacture.
Warning! Do not use materials with a flashpoint higher
than 60ºC (140ºF).
A 2- quart mixing bucket is provided to use
3/4
when transferring spray material from the original
container into the bucket for thinning and
measuring purposes (Fig. C).
A viscosity test cup is provided to determine the
"runout time" of the material being used.
f Before measuring for the proper viscosity, stir the
material thoroughly.
f Dip the viscosity cup into the material being sprayed
and fill the cup completely.
f With the cup held over the material container,
measure the amount of time it takes for the stream
of material flowing out to "break" or stop being a
constant stream out of the bottom of the cup (2
SET-UP
minutes or less) (Fig. C1). This is the "runout time"
Refer to the thinning table for information on the
thinning required for different materials.
f If material needs thinning, add the appropriate liquid
thinning material recommended by the manufacturer
(Fig. C2).
f It is possible to spray latex paint with this unit,
however, the required thinning may exceed material
manufacturer´s recommendation. Thin latex paint so
that it runs through viscosity cup in under 2 minutes.
The operator should con- sider the type of application
and final location of the project when spraying a
material that requires more than 2 min- utes to run
through the viscosity cup.

PREPARATION TIPS

f Always stir and strain the material thoroughly before
use.
f With any spraying job you should always ensure that
you have properly prepared the surface to get the best
finish. That is, all surfaces are free from dust, dirt, rust
and grease. Lightly pressure wash decks or exterior
surfaces and ensure that they are dry before spraying.
f Even though HVLP sprayers have very little
overspray, it is recommended that you mask all edges
and other areas and use drop cloths to protect your
floors and anything else in the spraying area that you
wish to remain untouched.
f Skin that forms on the top of paint can clog the
sprayer. Remove skin before mixing. Strain with a
funnel with a filter attached or through hosiery to
remove any impurities that could clog system.
f Before starting have gloves, paper towels, rags etc.
available for unexpected spills.
FILLING THE CANISTER (FIG. D)
f Check to make sure that the canister is completely
screwed onto the sprayer.
f Lay the sprayer on its side with the canister side lid
facing up.
f Unscrew the lid on the side of the canister.
f Pour the properly thinned and strained material to be
sprayed into the side fill canister (Fig. D).
RUNOUT TIME
