If you're in doubt concerning the nature of the metal surface you want to paint, test it with a magnet: aluminium will not attract the magnet. To paint aluminium, Valmour recommends to proceed according to the following 2 steps :
1- PREPARATION :
First, make sure your surface is clean by brushing it with a suitable brush. Avoid sandblasting as well as anti-rust products.
The metal also needs to be completely greaseless: if necessary, eliminate any grease with DILUVAL Thinner below.
Afterwards, apply a coat of WASH PRIMER, which will contribute to a better hold of a finishing paint on light alloy and non-ferrous metal.
2- FINISHING :
This is, strictly speaking, the painting which will give the final appearance. There are 2 types of paint:
. Monocomponent : an excellent value for money, this paint has the advantage of being less expensive and ready-to-use. Choose on of the following 3 appearances:
- mat : use Triple Mat FLAMBO
- satiny : use TOLEMAIL SPECIAL IRONWORKS
- shiny : use SUPER SHINY LACQUER .
3- PROTECTION :
This step is optional and allows to complete the finishing by adding a protective varnish to increase the life of the paint, and thereby prolonging the intervals between renovation. Use MARINE VARNISH LOUIS XIII.
Remarks :
If you want to apply a protective high temperature paint onto an aluminium surface, do not apply a primer which would make this paint loose its high temperature properties. Pickle the aluminium surface and afterwards directly apply one of the following high temperature paints : TOLEMAIL Silver High Temperature
or TOLEMAIL Black High Temperature.
