The different treatments of aluminum

Aluminum undergoes various treatments to prevent it from becoming clogged quickly Among these, the aluminum gates are covered with an anodized or lacquered finish that aims to bring durability and shine to the work.

Anodization

The anodized finish reveals the natural texture of aluminum.

Anodizing is an electrolytic surface treatment that creates an oxide layer to protect aluminum against daily aggressions. Current technologies allow the thickness of this layer (expressed in microns) to vary depending on the nature of the final exposure of the product. Thus, this treatment makes it possible to strengthen the resistance of aluminum against scratches, corrosion, cold and heat.

Thermolacquering (or powder coating)

Powder coating, also called «thermolacquering» consists of a surface treatment whose objective is to protect the aluminum surface from physical impacts. It is a thin layer of paint in the form of a powder that is applied to the surface with an electrostatic gun.

The major advantage of this method is on the ecological point. The powder does not contain any solvent.

Why is my aluminum gate tarnishing?

Among the reasons that can lead to tarnish or damage the aluminum gate finish:

  • The transport of impurities by the winds (dirt, dust, micro-organisms, abrasive elements such as dust grains).
  • Continuous heavy rains.
  • Urban pollution, with dense traffic and therefore a portal exposed to external aggressions.
  • Marine air

Once the impurities and dirt are embedded in the finish of the portal, it is very difficult to remove them. The more the dirt is present, the more it creates a film of dirt that contributes to the general aging of the aluminum portal.

Remove dust and deposits

It is necessary to follow certain cleaning rules using products adapted to aluminum, as well as to know their maintenance frequency, on the assumption that a regularly cleaned aluminum gate will prevent premature aging.

What are the solutions to restore color to my aluminum portal?

If the paint on your portal is not too damaged, a warm clear water, mixed with some neutral pH detergent will be sufficient. If the paint on your portal is not too damaged, a warm clear water, mixed with some neutral pH detergent will be sufficient.

  • Use a soft side sponge only If you are using detergent, consider rinsing the portal with clean water and drying it with a dry microfiber cloth.

Be careful here, this product is mainly for gates with thermal paint. Under no circumstances should this method be used if the treatment is anodization.

The aluminium carpentry renovator allows you to restore the brilliance of the painting and make your gate shine. This solution is much less expensive than using a craftsman to completely repaint.

Make sure the product is used on a clean surface (cleaned with water and detergent at neutral ph)

The application is done in a circular manner, by placing a small amount on a microfiber. A whitish deposit after a few minutes is formed and will then be removed with a clean cloth.
