The surface repair consists in applying different materials to correct the potential surface imperfections of the component, producing a homogeneous and prepared surface to apply the protection and surface finishing.

The protection is the application of a coating to produce sealing and isolation of the base component, protecting it from the exposure to aggressive atmospheres and increasing its useful life.


It means the application of putties and sealants to repair superficial imperfections and seal joints. The purpose is to get a homogeneous and smooth surface with a proper finish.

The composition of the applied putties and sealants depends on the surface to be treated and its purpose.


Sanding consists in smoothing surfaces with sandpaper or other items in order to let them ready for the surface finishing.We proceed to sand filled and previously repaired surfaces, as well as those surfaces that have not received a previous preparation and cleaning treatment.


This process consists in applying a layer of primer over the surface.

The primer is used to offer protection against corrosion in surfaces exposed to aggressive atmospheres. It also acts as a bridge between the surface and the finishing layer.

The chemical nature of the primer depends on both the material and the atmosphere to which the treated component will be exposed.

The application is carried out by mechanical (spraying) or manual means (rollers and brushes).


Coating technique that consists in the fusion with an electric arc of two metal wires. Its composition can be formed by different materials and in different proportions. This fusion of metal material is sprayed over the surface and a metal layer is adhered on the treated component. The total thickness of the screed is selected using different guidelines.

The choice of coating compound is made depending on the type of material on which it will be applied and the type of protection you want to perform. Among the materials to be applied, we can find: zinc, zinc/aluminium, aluminium, copper, brass, bronze…

The purpose of the metallization is to provide the best protection to the treated component.

Among its advantages we found:

· Long-lasting corrosion protection;

· Unlimited screed thickness;

· Component metallization of any dimension;

· Bigger adhesion value (with a good surface preparation);

· Excellent resistance to abrasion;

· Portable equipment, coating in the repair shop or on site;

· No risk of deformation (minimum heat transfer);

· No alteration of mechanical properties;

· No drying, curing, or cooling is required.


Intumescent paint is a passive protection system against fires. It consists in applying, manually or mechanically, a layer of variable thickness depending on the massiveness of the component and the required fire resistance quality in the component.

The intumescent paint has the ability to expand due to chemical reactions that occur when the temperature increases, becoming a foamy material, a thermal insulation, which remains adhered on the surfaces on which it has been applied.
