‘DIRECT TO RUST’ AND ‘DIRECT TO GALV’ PAINT
Hammerite - protecting your metal
Hammerite offers an easy to understand range of paints to enable you to protect and
rejuvenate metal. Hammerite offers technical excellence and quality you can count on.
For information on the full range of Hammerite products and colour range please refer
to the Hammerite Guide To Total Metalcare.

9) What temperature can Hammerite resist?

10) Can Hammerite be used under water?
No
11) After how many years should
Hammerite be repainted?
Direct To Rust: Current test shows performance of up
to eight years corrosion protection under “normal”
conditions, in high UV areas e.g. close to expanses of
water, it may be necessary to restore the appearance
with a single maintenance coat after roughly 3 years
depending on circumstances, particularly in Southern
European markets with high UV areas.
Direct To Galv: The appearance should be checked after
2 years, depending on the conditions the metal has
existed in (e.g. hard frosts, laying snow on paint film,
high UV areas) the coating may or may not need to be
rubbed back and one maintenance coat applied.
12) What should be used to degrease
galvanised steel?
The standard recommendation would be to use soapy
water which would remove any salts which might
encourage rusting where the substrate has lost its zinc
coating.
13) Can Hammerite Direct To Galv be
applied to roofs / flat roofs?
The product is more susceptible to wet adhesion failure
which rules out flat roofs as they are totally exposed
and it would be likely to find water sitting on the
coating for long periods.

15. ADHESION
Galvanised Steel provides a difficult surface on which to achieve good adhesion. Good surface preparation will
prevent most types of potential adhesion failure. The table below may be used as a guide to the causes of adhesion
failure and the solution to avoid this occurrence before use of Hammerite Direct to Galv Paint:
Cause of adhesion failure Remedy
Surface contamination – oil and grease Degrease with dilute detergent
Formation of soluble salts (particularly applicable Degrease with dilute detergent
to weathered galv)
Chromate factory pre-treatment Abrade to remove
New galv with large and bright spangle predominatly Weather until dull before application of DTG or use
zinc phosphoric acid etch primer followed by Special
Metals Primer
Corrosion of the zinc Refer to Surface Preparation section.
Etch primers or ‘mordant’ solutions Only use phosphoric acid etch primer – other acid
based primers do not cause adhesion failure but will
affect the thickness of the galvanised coating
Reaction between DTG and zinc (formation of fatty This is inevitable but sound surface preparation
acid soaps) (degrease and abrade) and the selection of alkyd for
this product maximises the adhesive strength of the
product. Prolonged performance will result from the
use of Special Metals Primer.
105% Any flaws in the painted substrate (scratches etc)
can allow water to get under the dry paint film to
encourage lifting of the paint particularly where water
is allowed to stand or pool on the surface Sound
surface preparation will prevent the product coming

should not be recommended for application with this
product (flat roofs must be avoided).
