BLACK JACK - Frequently
Asked Questions
Q. What is Black Jack?
A. Black Jack is
a safe, water based treatment which
neutralises rust and protects rusted iron and steel.
Q. How do you use it?
A. First
, you remove loose flaky rust to expose some underlying bare metal. Second, you
apply Black Jack, by spray, stiff brush or roller in thin even coats. A
second coat of Black Jack can then
be applied or you can apply any other paint topcoat.
Q. How many coats do you
need?
A. Black Jack is
a one coat rust treatment. However, the best results are achieved
with two coats. In applications not exposed to weathering, two coats give
outstanding protection, up to five years, without using topcoating systems.
Q. What is the
difference in performance between one coat and two coats of Black Jack with an
appropriate topcoating?
A. Depending
upon how severe the conditions are, one coat lasts from 6 months to 2 years.
Two coats will last for up to 5 years again depending on the severity of the
weather and the impermeable, compatible and flexible nature of the topcoat,
epoxy, polyurethane, bituminous coatings etc.
Q. Can you apply Black Jack to blast cleaned
steel?
A. Yes,
but there is no need to blast clean if using Black Jack unless to sweep blast.
Q. On what surfaces is it used?
A. Black Jack is
used on iron and steel structures.
Q. What happens if Black
Jack is used on aluminium?

Jack contains ingredients which chemically convert rust to a stable iron
oxide. The polymer in Black Jack provides
a protective coating over the stabilised surface.
