Preparation of Iron Surfaces

The preparation of iron surfaces is a fundamental step before applying paint.

Proper preparation helps ensure a quality finish, prevent rust and increase the durability of the paint.

Why is iron surface preparation essential?

A wrought iron gate showing advanced signs of corrosion, with rust spots and peeling paint, illustrating damage caused by exposure to sea air.

Iron, although aesthetic and robust, is vulnerable to corrosion and wear. Insufficient preparation can result in:

• Rapid corrosion:

Rust can develop under poorly applied paint.

• Paint peeling: An unprepared surface compromises the adhesion of the coating.

• Aesthetic defects:

An uneven finish diminishes the visual value of the ironwork.

Concrete example:

In a villa in Sainte-Maxime, a wrought iron gate exposed to the sea air showed signs of advanced corrosion.

Thanks to careful preparation including sandblasting and application of anti-rust treatments, we were able to restore its appearance while guaranteeing its durability.

Steps for preparing metal surfaces

1. Initial cleaning

A worker cleans a metal railing with a fine brush, in an outdoor environment, to remove dirt and residue prior to preparation.

A basic cleaning is the first step in removing dirt, grease and accumulated residue.

Recommended methods:

• Use a specific degreaser for metal.

• Clean complex areas with a fine wire brush.

Case study:

In a workshop in Grimaud, the initial cleaning of an iron balustrade revealed particularly damaged areas requiring more in-depth treatment.

2. Stripping to remove rust and old paint

A craftsman gently sandblasts an ornate wrought iron gate, removing rust and old layers of paint while preserving the designs.

Stripping is essential to remove old layers and prepare a blank surface.

Stripping techniques:

• Chemical stripping:

Use paint stripping gels or liquids to dissolve paint and rust.

• Mechanical stripping:

Wire brushes, grinders or sanders for manual removal.

• Sandblasting or aerogommage:

For fast and uniform preparation of large surfaces.

Case study:

In Roquebrune-sur-Argens, we restored an old grille using gentle sandblasting which preserved the decorative patterns while removing paint and rust residue.

3. Sanding to smooth the surface

A worker uses a sanding block with an abrasive disc to smooth a metal surface to demonstrate the action of sanding.

Sanding removes any residue left after stripping and leaves a perfectly smooth surface.

Tools needed:

• Medium grit sandpaper for large surfaces.

• Wire brushes for details and corners.

4. Application of an anti-rust treatment

The anti-rust treatment protects the metal against oxidation and improves paint adhesion.

Steps:

1. Apply a rust-inhibiting primer using a brush or spray gun.

2. Allow to dry according to manufacturer's recommendations.

Localized example:

In a residence in Draguignan, we applied a reinforced anti-rust treatment to wrought iron shutters exposed to humidity, guaranteeing long-lasting protection.

5. Dusting and finishing

A worker uses an industrial blower to remove dust residue from a prepared metal surface, ensuring a flawless finish.

Thorough dusting is essential to avoid residual particles before applying the final paint or varnish.

Technique:

Use a blower or dry cloth to remove residue.

Essential tools and products for preparing ironwork

Here is a list of tools and products needed for optimal preparation:

• Wire brushes:

For manual cleaning.

• Sanders and abrasives:

To smooth surfaces.

• Chemical strippers:

To remove old layers of paint.

• Anti-rust products:

To protect the metal in the long term.

• Specific paint for metal: For a resistant finish.

Professional tips for successful preparation

A craftsman restores a wrought iron gate surrounded by protective tarpaulins, illustrating the safety measures and precision of the work.

1. Work in a well-ventilated area to avoid inhalation of chemicals.

2. Test products on a small area before full application.

3. Protect unaffected areas with tape or tarps.

Concrete example:

When restoring a gate in Saint-Tropez, we used a protective tarpaulin to prevent the stripper from touching the adjacent walls.
