SURFACE PREPARATION
 
To get the best results, ensure surfaces to be
painted are sound, clean and dry (new surfaces
particularly must be fully dry) and free from all
defective or poorly adhering material such as dirt,
grease and wax.
Degrease where necessary with a suitable oil and
grease remover. Rinse with clean water to remove
residues.
 
APPLICATON INFORMATION
 
Apply a liberal coat of  Mordant
Solution by brush and allow to dry. If the surface
fails to turn black overall, the most likely cause is
contamination of the surface or the presence of a
factory applied pretreatment. Rinse the surface
thoroughly and abrade, using a suitable abrasive
paper. Remove all residues and re-apply, Avoid over-application
as pooling of the wash will result in the formation
of a fine brown deposit of copper.
After treatment the surface must be rinsed with
clean water to remove all residues and then
allowed to dry before priming.
The pre-treated surface should be overcoated
with an appropriate  metal primer
within 48 hours or before contamination can
recur.
 
 
APPLICATION METHOD
Brush only. Do not spray.
Practical Coverage
10 meters squared per litre
