How to use Fertan
Remove loose rust and scale if possible. Wire brushing is good but, particularly if using a powered wire brush, you really must wear eye protection.
Fertan needs to get to the rust so the surface needs to be clear of oil and grease. De-greasing agents are really cheap from motor factors. Then apply Fertan with brush, roller, sponge or spray.
1 litre covers approximately 12 - 15 square metres (140 sq. ft.) of oxidised metal surface.
Fertan reacts well on wet surfaces and in damp/wet conditions. In dry conditions wet the surface with a water spray. Most of the reaction takes place within 24 hours but, if you can wait 48 hours, particularly in cold conditions. By cold we mean near freezing.
Check that the rust is completely converted to a black layer. If not then insufficient was applied, so apply another coat to the non black areas. You can apply extra Fertan during the 24 - 48 hours time, it will only do good.
FERTAN can be applied on any other rust proofing treatment and is recommended for maintenance intervention on previously painted oxidises areas.
On light paint colours, any spattering of Fertan should be washed off within an hour of application.
Fertan is non-poisonous, harmless, non-irritating for humans and non-polluting for the environment.
It is sensible to point out that in case of contact with the skin you should wash with plenty of running water. If eye contact occurs, wash with plenty of running water and consult medical authorities. Fertan should not be consumed.
Fertan requires no particular safety precautions in storage. It is sufficient to keep the container closed.
Shelf life in closed containers is practically unlimited.
Sedimentation does not normally occur even during prolonged storage. Agitate the liquid if some precipitation or sedimentation has occurred.
In case of leak or breakage of containers it is recommended to dry with sawdust and wash with water.
