POR 15 RUST PREVENTIVE PAINT
DIRECTIONS FOR USE
This product is unlike any other paint or coating
you have used in the past. Please take time
to carefully read the instructions from beginning
to end before using POR 15. In addition, we
have provided you with questions and answers and
also tips and supplementary information. Please
also read instructions on the label of the can.
Reading this material will better acquaint you with
POR 15 and enable you to achieve a superior result.
POR 15 is a rust
preventive paint designed for application directly
on rusted or seasoned metal surfaces. It dries
to a rock-hard, non-porous finish that won't chip,
crack, or peel, and it prevents rust from re-occurring
by protecting metal from further exposure to moisture.
POR 15 is sensitive to UV light (sun) and must be
top coated for prolonged
exposure to sunlight. Topcoating is not required
for areas not exposed to sunlight.
are best; seasoned metal and sandblasted surfaces
are also good.
COAT SMOOTH METAL SURFACES (ie new metal, or
any aluminium / galvanising): Surface
must be dry and free of grease, oil or other foreign
substances which can be removed with our water based
product Marine Clean, use of solvent based preps
is not recommended. use POR 15 METAL READY
to prepare surface before painting. Use of "rust
converter" product is not recommended as they may
affect bonding of POR 15 to metal. POR 15
likes to adhere to surfaces with a
"tooth" rather than smooth, glossy surfaces.
Apply POR 15
Rust Preventive Paint directly to the sandblasted
OR RUSTED METAL:
First, wire brush loose
rust and scale. Then remove any grease
or oil with POR 15 Marine Clean and prep with POR
15 Metal Ready.
Do not use
Solvent based cleaners.
PROCEDURE: STIR CONTENTS
OF CAN THOROUGHLY before painting. Do not
shake. Then dispense a quantity of POR 15 into a
separate container and seal can immediately, ensuring
the groove is free of paint, use gladwrap
between the lid and the can. Refrigerate
unused portion of POR 15 for longer shelf life.
NOTE: left over portions of POR 15 should not be
put back into the can as this will shorten its shelf
Apply POR 15 in thin coats. Minimum of 2 coats for
general use, and minimum of 3 coats for Marine or
Industrial use. Topcoat when final coat is
dry but with slight remaining finger-drag, usually
Apply second coat when
first coat is tacky but almost dry (minimum 3
to 5 hours and not longer than 12).
If first coat is fully cured (more than 12 hours
old), wet sand first coat with 600 grit sandpaper
until gloss is dulled. Next, apply the second
coat of POR 15. Use same procedure for subsequent
Use 250 Kpa (30-35
lbs) pressure for normal gloss. Reduce pressure
for lower gloss 200 Kpa (20-25 lbs). Thin
only with POR 15 Solvent, if necessary, no more
COAT APPLICATION OVER POR 15 PRIOR TO FINISH PAINT
IF USING PRIMER:
Tie Coat Primer
provides an excellent sandable primer, that can
be applied over POR 15 from touch dry to up to a
year old with the only requirement that the surface
be free of grease, oil & foreign substances.
If using another primer then use the following method:
after the last coat of POR 15 has been applied,
wait approximately 45 minutes to 1 hour until the
POR 15 coating is tacky; then apply a light dust
coat of primer and let dry. Next, apply
a full coat of primer and follow normal top coating
procedures. If primer is lacquer based, apply
dust coat only after POR 15 is dry to touch, OR
To Topcoat a cured POR 15 SURFACE with a product
other than Tie Coat, wet sand with 600 grit until
gloss is dull, then paint.
Use POR 15 Solvent
or lacquer thinner for cleanup, which must be done
before POR 15 dries; once dry, POR 15 cannot be
removed by solvent. Avoid skin contact.
Remove from skin at once to avoid temporary staining.
USE OF GLOVES AND VENTILATING EQUIPMENT IS STRONGLY
RECOMMENDED. NOTE: Organic vapour particulate
respirators, NIOSH/MSHA approved must be used when spraying
POR 15. Moisture will shorten the life of
unused POR 15. Seal can immediately after
2 years or more. Opened can, properly used
with decanting out of the can, resealing with gladwrap
or similar up to 12 months.
most common reason for failure of POR-15 in the
marine application is the presence of moisture,
miniscule droplets of water remain trapped in
the rust and applying heated drying will remove
Always apply a minimum of 3 coats of POR 15
followed with good quality topcoats (normally 2
coats). Topcoating is essential below the
waterline topcoat, then apply antifoul.
In bilge areas always
make sure the area is dry (heatgun/hair dryer)
before applying POR-15, because these areas are always trouble spots.
In areas that have been extremely rusty,
eg. many millimetres of metal has been corroded
away, this can create a very porous surface, it
is likely to soak up preparation products like Metal
Ready, that then leach out later. The best
method of dealing with this is to give it all a
good chip - removing all loose rust, then a light
clean with a diluted mix of Marine Clean. Rinse
then use a heat gun to thoroughly dry out the metal.
Paint with a minimum of 3 coats of POR 15. In heavily rusted areas, apply a coat
of Black, Clear or Grey first, not Silver (in
some cases you will get a cosmetic rust colour
Silver can then be applied as a second or subsequent
coat for its high fill characteristics.
