• Filling deep holes and dents
• Work requiring durable mechanical reinforcement

This strength makes aluminium putty the solution of choice for car body repairs where reliability is paramount.

2. Excellent heat resistance:

The aluminium particles embedded in the Putty give it excellent thermal conductivity. Unlike other putties, it resists temperature variations without shrinking, blistering or peeling.

Average thermal resistance: up to 100 to 200°C, depending on application conditions and substrate. This means it can be used on areas close to the engine, the exhaust or parts exposed to the sun, without loss of performance or deformation.

3. Strong adhesion to metal substrates:

Another aspect of its resistance is its exceptional adhesion to bare metal, Galvanized steel, aluminium or old, sanded putties. This strong bond ensures that repairs last longer, even in the event of vibration, mechanical stress or differences in expansion between materials. To maintain this resistance, it is essential to carefully degrease the substrate and sand down to bare metal before application.

4. Foolproof durability :

In addition to its strength and heat resistance, aluminium Putty offers superior chemical resistance: it withstands exposure to moisture, grease and solvents, while retaining its cohesion over time. This is why it is often used as a base putty before a finishing putty, guaranteeing a durable, perfectly stable repair before painting.

Aluminium putty stands out for its complete mechanical, thermal and chemical resistance. Designed for professional bodybuilders, it ensures solid, long-lasting repairs, particularly on metal areas exposed to high stress. It's a reliable, technical and high-performance product, essential for guaranteeing perfect adhesion and maximum longevity of car repairs.

How do I use aluminium putty correctly?

Aluminium Putty is a product formulated for demanding metal repairs. Thanks to its composition enriched with aluminium particles, it offers optimum adhesion, high mechanical and thermal resistance, and forms a solid base for subsequent finishes. To achieve a professional, long-lasting result, it is essential to follow a precise application method.

1. Prepare the substrate correctly :

Preparation of the surface is the key to a successful repair:

• Clean and degrease the area to be repaired to remove oil, grease and dust
• Sand the surface down to the metal or over old sanded putty
• Remove dust carefully with compressed air or a clean cloth

Aluminium Putty will only adhere to a dry, clean surface. Any imperfection in preparation may lead to delamination or cracks.

2. Preparing the aluminium Putty :

Aluminium putty is a two-component product, requiring the addition of a Hardener :

• Hardener dosage: generally add 2 to 3% by volume of Putty.
• Homogeneous mixing: mix until a uniform colour is obtained, without streaks or unmixed areas.

Too much Hardener makes the Putty cure too quickly and become brittle, while too little will slow down drying and impair adhesion.

3. Applying aluminium putty :

To apply the product correctly:

• Spread in thin, even coats with a suitable spatula or spray gun for large surfaces.
• Avoid overthicknesses which can cause shrinkage or cracking.
• For deep repairs, apply several successive coats, allowing each coat to harden slightly.

4. Drying time and hardening :

Drying time varies according to temperature and Hardener dosage:

• At 20°C, complete hardening generally takes 20 to 30 minutes.
• The Putty becomes hard and sandable, ready for the next stage.

Be careful never to sand a fresh Putty, as this can cause irregularities and compromise the finish.

5. Sanding and finishing :

Once the Putty has hardened:

• Rough sanding with P80-P120 grit to obtain the desired shape
• Finish by sanding with P180-P240 grit before applying a Universal putty or a filling primer.
• The aluminium putty can then be covered with any type of finish or paint compatible with professional workshops.

6. Practical advice for bodybuilders :

A few practical tips for applying the product:

• Always work in a clean, ventilated area to avoid impurities.
• Clean the spray gun or spatula after use to protect the tools.
• Follow the dosage and drying times to ensure maximum adhesion and resistance.
• Store Putty in a dry place, away from heat and humidity.
