When you decide to make your workshop a DINITROL station, you also decide on more success. From that points onwards, we will support you as your partner in every respect. To ensure the high quality standards of professional corrosion protection, there are several prerequisites to fulfil. But here too, we are here to guide you every step of the way.

We have compiled the recommended equipment and essential application information. This should help guide you through the first step. We are happy to discuss the details with you at any time.

  • The walls should be made of a material that is easy to clean, such as stainless steel. The walls can also be coated with strippable paint or film.
  • The floor should be made of a non-slip material.
  • An oil separator should be installed.
  • Use a pressure washer for cleaning (Caution! Do not use a high-pressure lance).
  • We recommend using an endoscope to show customers rust that has formed in vehicle cavities.
  • When lifting the vehicle, we recommend using a four-post wheel-engaging lift, as it provides good visibility from below while working on the vehicle.
  • The products should preferably be stored in a separate part of the building. The storage area should have a room temperature of at least +15°C at all times.
  • Use hose suspensions to ensure safety in the workplace.
  • For best results and for your own safety, always keep the pumps and other equipment clean.
  • The working temperature in the station should never drop below +15°C or exceed +30°C.
  • Spray diagrams should be stored where they are easily accessible.
  • It is extremely important to keep the work area clean.
  • Always keep the material safety data sheets for all products used within easy reach. Always hand these to medical personnel in the event
    of an accident.
  • Wear protective clothing, such as overalls, gloves and face masks (i.e. masks with an active carbon filter) and ensure that all employees
    do so as well.


    • The ventilation system must be positioned so that contaminated air cannot enter the respiratory tracts.
    • Never apply corrosion protection agent without switching on the ventilation. The ventilation should also be switched on when the vehicle engine is running.
    • The pump equipment should be screened off from the work area, if possible.
    • The air circulation below the vehicle should always be strong enough to prevent the formation of mist. The speed of the air circulation 20 cm below the lifted vehicle should be approx. 0.3 m/sec.
    • Circulation of ventilation air is only permitted for drying.
    • The ventilation system should be equipped with an indicator that shows when air circulation is not sufficient. The ventilation should not increase the regular noise level in the workplace. The noise emitted by the ventilation system should be at least 10 dB(A) lower than the regular noise level in the workplace. The noise level can be reduced by insulating the air channels and the ventilation, for example. The ventilation system should be housed outside the workplace.
    • Operating instructions for the ventilation system should be made available to users.
    • The ventilation system must undergo regular maintenance.


  • Since the corrosion protection product is dark in colour and there are many parts that can cast shadows on the vehicle underbody, lamps with approx. 500 Lux must be used.
  • The lamps should be placed so that they cannot be sprayed with corrosion protection product.
  • A handheld torch should be made available for inspection of the wheelhouses and cavities, etc.


  • The pipe connections must be equipped for a pressure of at least 300 bar.

Cleaning and degreasing

  • Protective gloves should be worn when using a cold degreaser. If the degreaser is sprayed, also wear the recommended face mask and eye protection.
  • Use a petroleum-based solvent for cleaning or degreasing.


Fire safety

  • Open flames, welding work and smoking are prohibited in the building where the work takes place.
  • A fire extinguisher must be easily accessible and stored in a secure place.
  • Some corrosion protection products are flammable or inflammable, and must be stored in accordance with local laws and regulations.
  • Containers with corrosion protection product must never be heated over an open flame.

Protective equipment

  • Gloves made of a suitable material, i.e. oil- resistant plastic, and face masks must be made available for employees to use when required. Lotion must be used on exposed skin. Apply a suitable, oil-resistant lotion to exposed body parts.
  • This lotion should be applied before commencing work. Do not use thinners or other harmful solvents to clean the skin. Do not use compressed air for personal cleaning.

Rust proofing work

  • A high-pressure airless system should preferably used for rust proofing work.
  • The hose for the system must be a hydraulic hose with steel casing. It must be resistant to four times the maximum applied pressure.
  • If the hose becomes damaged, it must be replaced. Do not repair the hose! Never exchange the hose connections.
  • The hose between the pump equipment and the spray gun must be earthed to prevent static electricity.
  • The hose between the spray gun and the nozzle (extension hose for internal treatment) must be protected by a plastic hose, which also covers the hydraulic connections. Note: If someone is sprayed by the product at high pressure, the product penetrates deep into human tissue. This can cause severe injury and may lead to amputation of the injured body part. If such an accident occurs, call for emergency medical assistance immediately.


  • It is important that the vehicle is clean and dry before starting rust proofing work.
  • The vehicle can be dried using various methods:
  • Portable or stationary dryers can be used to blow warm air on the vehicle underbody.
  • The vehicle can also dry indoors overnight. Warning: Never use open flames to dry the vehicle!

General application information

  • The engine, gearbox, radiator, silencer, and differential must not be sprayed, as they heat up while driving and the products have insulating properties.
  • The drive shaft must not be sprayed, due to risk of imbalance.
  • The brake drums must be protected.
  • A systematic approach must be used when applying the products to ensure that no areas are left untreated.
