Dilute with clean mains water, as follows:

 

Stage one                        Degreaser                 -    1 part water to 1 part product

Stage two                        Conditioner              -    9 parts water to 1 part product

Stage three                     Metalblak                 -    3 parts water to 1 part product

                                        Brassblak                  -    4 parts water to 1 part product

                                        Zincblak                    -    4 parts water to 1 part product

Stage four                        Oil sealer                   -    use as supplied                        

 

 

For best results the process temperature should be maintained at 18C.

 

 

Stage one - Degreasing

Antique Effect

 

To achieve an aged effect with Zinc, brass and copper  - relieve the components to allow the base metal to show through and seal with a lacquer to maintain finish.
