Aluminum antique finish

Aluminum as a furniture substrate may be much less than the wood, but the aluminum furniture is quite well popular in the market. Aluminum is much used to make metal furniture since it is easily handled, machined and shaped and have high durability. Aluminum in various model and shape can be found in many furniture products. (See our previous article: aluminum for furniture). Although aluminum can be exposed in the unfinished state, but we can finish the aluminum to produce more attractive appearance and more durable product. There are many finishing models and color can be generated for the aluminum, and now in this article we want to share the antique finish for aluminum. It it’s the finishing for aluminum with the application of stain and glaze with special techniques same as finishing process in the wood furniture finishing.

Here is the finishing process step by step.
  • 1. Application of metal primer coat.
In this finish basically we used the finishing process with NC finishing material. To generated good adhesion to the finishing layer then a the metal primer coat is needed. It is the paint or coating that serves to do as the "connector" between the NC finish with the metal. It is applied as the first coating on the metal before the application of NC or varnish, stain or glaze application. In this finishing process we used a clear metal primer (no color metal primer), since we want to make a semi transparent finish. The primer metal coat was layered as the first coat by spray wet evenly the aluminum surface. Then we waited for about 30 minutes to let the coat dry.
  • 2. Application of stain.
Stain was used to color the aluminum to produce the desired finish color. We used a black toner stain. Toner stain is a stain with some clear coat in the mixture. We mixed black stain with some  vinyl sealer (about 5 %) to make the toner. The sealer in the stain mixed helps the stain to attach better for the aluminum surface. The black toner was sprayed evenly all over the aluminum surface. The toner stain color blended with the basic color of the aluminum metal to make a dark aluminum metal color. To make antique effect and more life impression, we did some highlight to the stain. We wiped slightly the stain layer with steel wool at some parts to make more life finishing looked.
  • 3. Application of clear coating.
The next process is the sealer application. One coat of vinyl sealer was layered on the stain to provide protection layer to the stain and give smooth surface before glaze application. Vinyl sealer was applied by spray evenly all over the surface. We let the vinyl sealer layer for about 20 minutes to dry.

  • 4. Application of glaze.
Glaze was applied to form the dark black color and to make antic effect in the finishing. Glaze was poured to overall surface and wiped off by rag and brushed to get the even layer of glaze coat. Some highlighted with the steel wool was done to produce the antique and old looked impression. We let the glaze for about 60 minutes to dry.
  • 5. Application of top coat.
After the glaze layer is dry, then we blown the glaze layer to clean it for the steel wool dust or any other dirt. We also checked the color and effect of the finish, to make sure we got the proper color and effect before we applied the top coat layer. We sprayed 15 sheen NC top coat as the last layer. We waited for 30 minutes until the top coat layer to dry, and we checked the film layer and finished color resulted. Since we got rough surface, then we did lightly scuff sanding to the top coat and applied one more layer of top coat. The result was an antique black metal aluminum finish.
