The painting process at Mantena, step by step

Mantena helps you with the entire painting process – from sand-blasting and surface treatment to the finished painted object. All paint jobs at Mantena start with one of our professionals taking a close look at the job to be done. We measure the thickness of the primer and paint where necessary, and we end all paint jobs with a thorough final inspection.

These are our 10 steps to a quality paint job:

1. Review of the work to be done, carried out by one of Mantena’s paint experts
2. Cleaning the area and removing any components that are not to be painted
3. Washing and degreasing
4. Repairing damage, filling and rubbing down rough areas, removing any rust
5. Rubbing down existing paint for optimum adhesion
6. Masking, priming and rubbing down the primer where necessary
7. Blast-cleaning, washing and degreasing and removal of any specks of dust
8. Painting and possible application of clear varnish
9. De-masking and re-installing components
10. Final inspection

Spot-painting

If there is only minor damage to the object that needs painting, ‘spot painting’ (sometimes called ‘smart painting’) may be the sensible option. Spot-painting is environmentally friendly and cost-effective for you as a customer.

The work is confined to the areas that are actually damaged. The new paint is merged into the old with a spot blender. After drying, the transition is polished for a perfect finish.

Wet painting of components and industrial products

Mantena can paint components and structural elements of all kinds, with all types of surface treatment.

For component and structural paint jobs, sand-blasting may be required before painting, with the associated requirements for the sand-blasting and the thickness of primer and topcoat products. Mantena paints all components and structural elements in accordance with the applicable requirements and documentation needs.
