RUSTY METAL PRIMER

Dulux recently purchased 400ltrs of FERONITE to prime rusty areas on an Oil Rig

It Converts, Inhibits & Seals rust in one application.

What is Feronite Rusty Metal Primer?
Feronite rusty metal primer is based on the successful Feronite tannin pre treatment for rusty surfaces. It is non-toxic non-flammable water based chemical comprising highly protective resins, tannin extracts and anti corrosive additives.  When applied to rust, the tannin components react with the oxides of iron present to produce a stable black compound (chelated iron tannate) and this becomes incorporated in the resin layer as the coating dries. The result is a strongly bonded protective surface coating which includes the elements of the original rust converted to an inert passivated form with strongly anti-corrosive characteristics.

Feronite Rusty Metal Primer is a new coating which chemically eliminates surface rust and primes the steel surface in one application. It does away with tedious and costly surface preparation such as blasting or grinding, followed by application of solvent based anti-corrosive priming paints. Feronite Rusty Metal Primer replaces all this and can be applied to damp surfaces so weather conditions are not a limitation.

Uses for Feronite Rusty Metal Primer
Feronite Rusty Metal Primer is for treatment and preparation of rusted steel or degraded galvanised surfaces starting to show signs of rusting:

  • Steel structures of all kinds
  • Roofs and Guttering
  • Sheds
  • Balustrades and wrought iron
  • Fencing
  • Bridgework
  • Boat fittings
  • Trailer axles and springs and frames
  • Water front fittings
 
Feronite Repair Procedure - ANMM Lighthouse

 

During the Australian National Maritime Museum ‘Wooden and Classic Boat Festival’ in October 2012 it was noticed that the lighthouse was displaying visible signs of corrosion where the riveted plates overlap. If this is not treated it will become a serious issue as the rust (ferrous oxide expands at 16 times the thickness of the original metal rusting) will gradually place significant pressure on the rivets and start to distort the steel plate at the lap joints. This in turn would cause the degridation of a valuable Maritime Heritage artefact.

A Rusty Metal Skeptic Fixes His Cast Iron Keel

 

By John – A sceptical rusty metal customer

I have a Jeanneau 31 with a cast iron keel which developed multiple rust spots that were evident at annual haul-out and anti-foul time and the rust became progressively worse each year.   I tried many quick fixes but none seemed to work.

After reviewing many systems at the Australian Wooden Boat Festival in Hobart in February 2017, I was impressed with the Feronite Rusty Metal Primer / Bote Cote system and carried out a trial on a cast iron plate which I left at the water’s edge.  After 4 months of daily tidal washing cycles, it performed perfectly with no hint of rust appearing.  This gave me confidence to go to the effort involved to apply the product to my keel.

I used the following steps;

  1. Remove old antifoul. This step was delightfully easy by applying the “Lemon Peel” stripper product.  After applying a very thick layer, I covered it with plastic overnight and the old stuff just literally fell off with a paint scraper.
  2. Prepare the surface.  I then removed the majority of some old red-lead primer and grey epoxy filler with a combo of sharp scraper and rotary wire brush.  There were many (around 100) pockets of rust which appeared as dark stains, some big (50c coin) and many small (pencil diameter), which I dug out with a sharp point and then ground out with rotary wire brush.  The wire brushing left areas of bright metal which is not ideal for the Feronite Rusty Metal Primer as it needs some surface rust to react and bind to, so I brushed on some hydrogen peroxide to promote surface rust blooming.  The next morning I hosed the whole keel down with a pressure washer.
  3. Apply Feronite Rusty Metal Primer x two (2) coats. This turns dark brown/ black after it reacts with the rust.
  4. Two (2) coats of the Bote Cote Epoxy Resin were then applied as per instructions.
  5. The next day I brushed out the rust pockets with acetone (styrene would be better) and filled all the holes with epoxy paste that you mix as per instructions.    After this cured hard overnight, I sanded the whole keel to remove any high spots and was left with a reasonably smooth surface.   I then applied another 2 coats of Bote-Cote making 4 coats in total and fared this off again ready for the usual primer and anti-foul.

Previously there were rust spots starting to appear within a month but this time there is nothing at all after diving on it 2 months later.   I will monitor next year and update the Jeanneau post with the performance of Feronite Rusty Metal Primer & Bote Cote Epoxy Resin.
