Mercasol 1 – Professional Automotive Anti-Corrosion Treatment, 1 L

Automotive anti-corrosion treatment with Mercasol 1

One of the most important steps in ensuring a vehicle’s longevity. This highly effective, solvent-based anti-rust product is specially formulated to provide exceptional protection in hidden cavities, seams and joints, where the risk of corrosion is highest.

How does it work?

A professional-grade anti-corrosion product based on a unique formula of waxes, sulphonates and special oils. Unlike standard solutions, this product forms a durable, greasy and highly moisture-repellent layer after application. Its low viscosity ensures deep penetration, allowing it to effectively reach seams, joints and metal folds. The liquid penetrates deep into even microscopic cracks and hard-to-reach cavities in the car frame.

Once dry, the product remains flexible and forms a brown, moisture-repellent wax film that does not crack even under sharp temperature fluctuations. This makes it an ideal choice for Latvia’s changeable weather, where salt and moisture are a constant threat to metal surfaces.

The product has been evaluated in comparative tests and approved for use on most car makes.

Key technical advantages

When carrying out anti-corrosion treatment, it is important to use materials that not only coat the surface but also provide long-term protection.

• Deep penetration: Thanks to its high penetrating ability, the product effectively reaches seams, gaps and structural joints.
• Effective corrosion protection: Excellent adhesion to metal surfaces, preventing air and moisture from reaching them.
• Environmental sustainability: The product complies with the strict SS 18 65 11 standard and contains a significant proportion of renewable raw materials, reducing its environmental impact without compromising performance.
• Versatility: Can be used both as a standalone cavity protection product and as a primer before applying thicker underbody coatings.
• Proven compatibility: Mercasol 1 has been tested and approved for use with various corrosion protection systems and is compatible with many car makes.

Applications and compatibility

Mercasol 1 is designed to protect hidden structures and joint areas of cars against corrosion, and can also be used as a base coat in a system with Mercasol underbody coatings.

Internal cavities: Doors, sills, chassis rails and boot lids, where moisture accumulation promotes rust formation.

Seams and joints: Flanges and structural joints that need protection against the ingress of moisture and salt.

As a base coat for exposed surfaces: Can be used as a base layer in underbody protection systems in combination with Mercasol 3 or Mercasol 3AL, improving the adhesion of the next layer to the surface.

The product is compatible with most modern automotive corrosion protection systems and has been tested for use on factory coatings.

Instructions for use

For maximum effectiveness, the anti-rust treatment process must be followed carefully:

• Surface preparation: Before treatment, make sure the surface is clean and dry. Remove all loose rust, dirt, oil and road salt residue. Remember—proper preparation accounts for 50% of the result.
• Application: The product can be applied with a spray gun using suitable equipment with cavity tubes. The optimum working temperature is between +15°C and +25°C.
• Drying time: Drying time depends on the air humidity. At +23°C and 50% relative humidity, it is approximately 8 hours.

If you plan to apply Mercasol 3 or 3AL, it is recommended to wait at least 1 hour after applying Mercasol 1.

Compatibility and system use

Mercasol is part of a multi-layer anti-corrosion protection system in which proper surface preparation is essential.

Important: Mercasol 1 and Mercasol 3 products are not intended for direct application to active rust.

For rusty surfaces, we recommend using Owatrol Oil as the first stabilising layer. It penetrates the rust, stops its progression and forms a solid, stable coating that prepares the surface for further treatment. Available in: 300 ml aerosol, 0.5 l and 1 l packs.

After stabilising the surface:

• Mercasol 1 protects internal cavities after surface stabilisation.
• Mercasol 3 AL (bronze) provides an exterior protective layer with high mechanical and moisture resistance, thanks to its aluminium pigment content.
• Mercasol 3 BL (black) is an alternative coating with the same protective properties, chosen according to aesthetic or application requirements.

Mercasol products are available:

• In a 600 ml aerosol format, equipped with a special nozzle for precise application
• The 1 l pack is designed for use with a pneumatic spray gun and a special cavity probe.

Together, these layers form a complete corrosion protection system for the car body and underbody, with clearly defined functions: rust stabilisation, cavity protection and an external mechanical barrier.
