PREPARATION (sanding and cleaning)

The procedures necessary for repair and painting operations carried out on metal sheet supplied as a spare part are listed below.

NOTE: Metal sheeting supplied as a spare part is treated by cataphoresis.

PREPARATION (sanding and cleaning)

Operate on the affected part by feathering the existing layers of paint with the prescribed abrasive paper.

SURFACING

Repair operations carried out on sheet metal usually involve a surfacing phase.

Prepare filler by adding the relevant catalyst in the proportions recommended by the manufacturer; mix the product and apply a coating sufficient to cover the existing undulations. Allow the filler to dry completely before proceeding to the next stage.

SANDING

Dry or wet sanding may be carried out by hand or using an electric or pneumatic sander fitted with the prescribed abrasive paper.

MASKING

The areas surrounding the area to be repaired should be masked with sheets of paper fixed to the surface with adhesive tape.

The importance of this operation should not be underestimated and should be carried out, like all other operations, taking all the necessary precautions to avoid possible damage.

Masking should be applied after the filling has been sanded, and removed after the primer has been sanded (as the masking paper becomes impregnated with dust, fumes and abrasive particles) and replaced before enamelling.

PRIMER APPLICATION

Primer is applied to bare metal surfaces as a protection against corrosion; when the primer is dry and after curing, apply the undercoat.

1. Paint
2. Enamel
3. Undercoat
4. Cataphoresis (Primer)
5. Galvanization
6. Sheet metal

Thoroughly clean the the affected areas with silicone-proof products.
