The following is a brief guide
on some frequently asked questions...
Do I need to use Marine Clean and Metal Ready every time
I use POR 15® Rust Preventive Paint?
No. It will depend on what you
are doing - here are some quick guides...
Painting a rusty gate or general farm machinery - as long as
it is clean just wire brush, dry and paint with POR 15®
Rust Preventive Paint.
I want to do some general car repairs, around the windows, doors
and sills etc.
Just prep around the rusted area, and remove as much rust
as you can by hand, again if the area is clean, use some Metal
Ready to remove rust and prep both new shiny metal or old rusty
metal, Metal Ready will also take any weld scale off, rinse
with water, allow to dry and paint with POR 15® Rust Preventive
Paint.
I want to paint my floor pan / chassis / underbody areas.
These areas are normally heavily contaminated with just
about everything - oils, waxes, grease, dirt etc. The use of
Marine Clean is very important in these areas, because without
it the whole paint system performance, can break down. Rinse
well, follow with Metal Ready, rinse and dry. Then apply POR
15® Rust Preventive Paint.
I've just sandblasted some steel, do I need Marine Clean and
Metal Ready?
No, just paint it with POR 15® Rust Preventive
Paint - the surface is already cleaned and keyed.
When painting POR 15® Rust Preventive Paint on aluminium
should you always use Metal Ready?
Yes, and generally the use of Marine Clean is also advisable.
Will POR 15® Rust Preventive Paint stick to wood
or concrete?
Yes, POR 15® Rust Preventive Paint will stick
to just about anything, as long as the surface is clean, and
it has something to stick to, eg. the surface has some profile.
Can I recoat POR 15® Rust Preventive Paint with any
paint?
Yes, POR 15® Rust Preventive Paint is compatible
with all paints. Just be sure to follow the recoating directions.
How do I topcoat POR 15® Rust Preventive Paint? -
the three options
1. Apply topcoat within 48 hours (12 hours for non POR 15®
topcoats) of the last coat of POR 15® Rust Preventive Paint
being touch dry.
2. Apply our Tie-Coat primer - at any stage from touch dry.
3. Allow surface to fully cure (96 hours) sand POR 15® Rust
Preventive Paint - this is not an easy job, on such a tough
surface.
We recommend option 1 or 2, as being the simplest and most
cost effective.
Why do I need to "topcoat" over POR 15® Rust Preventive
Paint anyway?
You don't unless the POR 15® Rust Preventive
Paint will be exposed to sunlight (UV rays tend to discolour
the finish) or you are after a definite colour. For example
the Black POR 15® Rust Preventive Paint will go completely
matt with UV exposure.
