COMPLETE DIRECTIONS FOR USE OF
POR-15 RUST PREVENTATIVE PAINT
Please note: 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 POR15. If temperature is below 12ºC do not apply POR15 unless the object to be painted has been heated. Surface preparation: Rusted surfaces are best; seasoned metal and sandblasted surfaces are also good. SANDBLASTED SURFACES; Apply POR15 Rust Preventive Paint directly to the sandblasted surface. SEASONED OR RUSTED METAL: First, wire brush loose rust and scale. Then remove any grease or oil with POR15 Marine Clean and prep with POR15 Metal Ready, leave Metal Ready wet on the surface for 20-30 minutes, then wash off with water. Dry the surface completely. Failure to do this may trap moisture under the paint and rust will form again. TO COAT SMOOTH METAL SURFACES,i.e. 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. Do not use solvent based cleaner’s prior to painting.
1. Washing:
All surfaces to be painted must be
absolutely clean and grease free. Washing with a water-based degreaser such
as Marine Clean followed by a heavy rinsing with clear water is necessary to
insure a clean surface. The use of a water-based product is important so as
to avoid the possibility of a solvent film or residue, which will impede the
adherence of POR-15. At this point all loose materiel and scabs, or multiple
layers of rust must be removed. Any moisture trapped within these multiple
layers of oxidation will cause rusting later on.
Marine Clean is packaged in a concentrated form
and must be diluted with water. A minimum ratio of 1:1 is necessary. It may
be diluted up to 10 parts water to 1 part cleaner depending on the amount of
dirt or grime to be removed. It may be diluted even further and used as a
household cleaner on walls, floors, counter tops or as a pre-wash on grease
stained clothing. Apply Marine Clean with a spray bottle or brush and allow
it to soak before rinsing. If Marine Clean appears to dry too quickly, add
more water. Repeat as necessary until parts are perfectly clean. A scouring
pad may be used on heavily soiled areas. Complete drying is not necessary
before proceeding with Metal-Ready. Simply allow several hours for excess
water to drip off.
2. Etching:
Metal-Ready is a phosphoric based acid etch that is applied at full strength
after degreasing to temporarily neutralize rust and leave a coating of zinc
phosphate which will aid in the adhesion of paint. This is especially
important on areas that contain new metal and/or welds. It should remain wet
for a minimum of fifteen to twenty
minutes (without allowing to dry)
before rinsing thoroughly with clear water.
Scuffing surfaces while rinsing will insure an even higher level of
adhesion. If it is not possible or convenient to rinse with a water hose it
is acceptable to remove all excess Metal Ready with a clean sponge and fresh
water. At this point the surfaces to be painted must be allowed to dry
completely. This means bone dry. If moisture is trapped beneath the
surface of the paint, oxidation will occur. A white powdery residue will
remain with some applications. This is normal and can be blown off with
compressed air, wiped with a clean cloth or painted over. Metal-Ready can
also be used as a complete rust remover if left in contact with the metal
for a longer period of time. Soaking parts in a non-metallic container of
Metal-Ready for 24-48 hours will completely remove all rust and prepare the
surfaces for paint. Exterior body panels can be made rust free with the use
of a scuff pad and Metal-Ready.
3.
APPLY POR-15 by brush at full strength or diluted a
maximum of 5% with Por Solvent only, before spraying. It should be stirred
and not shaken before each use. Regardless of what method you choose, POR-15
will dry to a completely smooth finish leaving no brush marks. It is
recommended to dilute as little as possible in order to retain the full
strength of the paint. An exact dilution rate is not given, as this will
vary with temperature, humidity, equipment and line pressure. Test spray a
small area and adjust as necessary. Full gloss finish 30-35 psi, lower gloss
20-25 psi. Lacquer thinner may be used for clean up. A disposable air filter
must be installed directly on your spray gun in addition to any other
filters or traps in the air supply system. POR-15 is moisture sensitive and
even minute amounts of moisture will cause failure of the paint before it
has cured. These filters are available from your POR-15 supplier.
A minimum of two thin coats (1-2 mil) is to be applied with approximately 4-5 hours between coats. This will vary depending on humidity levels. POR-15 will dry faster at high humidity, but normal humidity is the desired condition. NOTE: Bubbling will start to occur when humidity is @ 50% or higher leaving a pebbly-type surface. We recommend the use of a small humidity meter. . When the first coat is tacky, but will not transfer paint to your finger when touched, the second coat should be applied. Follow the same procedure when top coating with other paints or body fillers. If the second coat is applied too soon, bubbles will form as the base coat releases carbon dioxide in the drying process. If the second coat is applied too late it will not adhere because of the slick surface and will peel. If you waited longer that 24 hours to apply a top coat TIE-COAT PRIMER or ETCHING PRIMER required.
4.
POR-15 is UV sensitive. The chemical that gives paint it's
ultra-violet protection causes a slight weakness in paint and it is for this
reason it is not present in Por-15. If the painted surface is in direct
exposure to the sun it must be top coated to retain its finish. You may use
any type or solvent base of paint or fillers, except a clear to achieve
this. The usual result of an unprotected finish exposed to the sun is a
complete loss of color with no return of oxidation. Ask your Por-15
distributor or dealer for information on our extensive line of incredibly
tough, UV protected finish coatings.
Safety Considerations: POR-15 contains isocyanates. Because of this you must take the necessary precautions to avoid the inhaling of the paint fumes. When spraying POR-15 in an enclosed area, the use of an outside air source system is required. When brushing, you will create fewer fumes but still must insure adequate ventilation. Keep out of reach of children and pets, etc. Harmful or fatal if swallowed. MSDS sheet available upon request.
CLEAN UP Use
POR15 Solvent or lacquer thinner for clean up, which must be done before
POR15 dries; once dry, POR15 cannot be removed by solvent. Avoid skin
contact. Remove from skin at once to avoid temporary staining.
MARINE TIPS * Always apply a minimum of 3 coats of POR15 (90-120cu’m) followed with good quality topcoats (normally 2 coats). Top -coating is essential below the waterline - topcoat then apply antifoul. * In bilges areas always apply some extra coats because these areas are always trouble spots. * The use of a heat gun to ensure that the metal is dry prior to painting is a good idea especially in permanently wet areas, like bilges. * 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 dilute mix of Marine Clean, rinse, then use a heat gun to thoroughly dry out the metal - then paint with a minimum of 4 coats of POR15. * Again in heavily rusted areas, apply a coat of Black, Clear or Grey first, not Silver. Silver can then be applied as a second or subsequent coat for its high fill characteristics. Other Helpful Hints:
