Professional blasting is the ultimate technical solution for removing corrosion and preparing metal surfaces, guaranteeing maximum durability anticorrosive protection.
What is blasting?
It is an industrial abrasive cleaning process that consists of projecting abrasive particles at high pressure onto a metal surface. This technique effectively removes rust, old paint, scale, and contaminants, leaving the metal completely clean and with the ideal roughness profile for optimal adhesion of high-performance industrial coatings in the demanding marine environment.
Blasting and anticorrosive protection
Corrosion is the main enemy of structures in saline environments. The abrasive treatment not only cleans but also prepares the metal to receive special paints that act as physical barriers against oxidation, extending the lifespan of naval hulls and superstructures through high-resistance protective layers.
Surface preparation
The quality of any industrial paint depends entirely on the prior preparation of the substrate. Through the abrasive process, an internationally standardized degree of cleanliness is achieved, eliminating microscopic impurities that would otherwise cause premature detachment of the coating, guaranteeing a uniform and protected final finish.
High-performance industrial painting
Once the necessary level of cleanliness is achieved, the application of specialized paint schemes is fundamental. These epoxy and polyurethane coatings, applied over correctly treated surfaces, offer superior resistance to impact, abrasion, and prolonged exposure to the elements typical of maritime operations.
Professional naval maintenance
Vessels subjected to periodic maintenance with abrasive equipment keep their structural integrity intact. This procedure is key to preventing weakening from generalized corrosion, ensuring that ships comply with the seaworthiness standards demanded by global classification societies in the maritime industry sector.
Industrial coatings and durability
The investment in quality coatings is only justified if the surface was treated by impact cleaning. This combination ensures that metal infrastructures, from ballast tanks to cargo holds, withstand the most demanding service cycles without suffering significant structural damage from chemical or mechanical oxidation.
Metal structures in hostile environments
Port facilities and docks require special attention due to their constant exposure. The abrasive treatment allows renovating large steel areas quickly, removing rust layers that weaken structures, thus facilitating comprehensive protection that minimizes long-term repair costs for operating companies.
Maritime industry and efficiency
Efficiency in maritime transport depends on smooth and clean hulls. The removal of marine organisms and rust reduces friction, improving the ship's hydrodynamics. This translates into lower fuel consumption and superior performance on all commercial routes operating under highly demanding conditions.
Frequently Asked Questions
Blasting is an industrial process where abrasive particles are propelled at high speed against a metal surface. This method serves to deeply clean parts and structures, removing rust, degraded paint, mill scale, and other contaminants that prevent proper protection. It is the indispensable preliminary step before applying any industrial paint system, as it guarantees that the coating adheres perfectly to the virgin metal, creating a durable barrier against corrosive external agents, thus ensuring the physical integrity of the treated equipment.
TECNAVAL Industrial Solutions S.A.S. can solve this technical need through the use of high-efficiency equipment and expert personnel in Cartagena. We apply the cleaning grades required by international regulations, ensuring the surface is free of contaminants to receive high-performance paint schemes. Our operational capacity allows us to service both large vessel hulls and complex industrial metal structures, achieving uniform finishes that meet the most demanding technical specifications of the naval and maritime sector, prolonging the operational life of your assets in the face of the severe saline environment.
The main benefit is the total eradication of corrosion spots that weaken the ship's steel. By removing rust layers and old damaged paint, a clean substrate is exposed that allows visual inspection for pitting or structural damage requiring immediate repair. Additionally, this method creates a specific roughness profile that acts as a mechanical anchor, which is vital for current marine paints, especially antifouling ones, to work correctly, reducing the ship's hydrodynamic friction during navigation and, consequently, optimizing its energy consumption and overall operational performance.
TECNAVAL Industrial Solutions S.A.S. can meet this requirement by guaranteeing a surface finish that maximizes the anticorrosive protection of your vessels. Our processes are designed to be fast and precise, minimizing stay times in dry dock or at the pier so that your vessel returns to its commercial routes as soon as possible. We use the appropriate abrasives for each type of metal, avoiding damage from over-cleaning or deformations in thin plates. With our intervention, you obtain a surface treated under superior quality standards, which ensures that your paint schemes last the time projected by the manufacturer.
It is recommended to perform this treatment when current coatings show signs of peeling, bubbling, or evident corrosion that cannot be treated using conventional methods like manual sanding. It is also imperative to apply blasting during major shipyard repairs, when new steel has been replaced, or when seeking to improve the paint scheme to achieve more years of protection. The frequency should be aligned with the vessel's preventive maintenance plan and the recommendations of classification societies, which usually require hull inspections where abrasive cleaning is necessary to evaluate the real condition of the hull.
TECNAVAL Industrial Solutions S.A.S. can solve your fleet's maintenance needs by scheduling highly efficient abrasive cleaning sessions in Cartagena. Our technicians evaluate the degradation state of your surfaces to determine if the treatment should be localized or total, thus ensuring efficient use of resources and budget. We handle all the necessary logistics to execute these processes in safe and controlled conditions, complying with local regulations on abrasive waste management. With our technical advice, you will know exactly when it is the right time to intervene, avoiding higher costs from uncontrolled corrosion.
The versatility of this process allows treating a wide variety of metal surfaces. It is primarily used on steel vessel hulls, decks, ballast tanks, cargo holds, piping, dock structures, and heavy industrial machinery. Depending on the substrate's hardness and the type of contaminant to be removed, different types of abrasives can be selected, from heavy minerals to softer materials, allowing work on both naval steel and other alloys. It is a universal solution for any structure exposed to extreme environments that needs exhaustive cleaning and high-quality technical surface preparation.
TECNAVAL Industrial Solutions S.A.S. can solve your surface preparation challenges regardless of the structure's complexity. We have compressed air equipment and precision nozzles that allow us to reach confined areas or difficult geometries where other methods fail. We evaluate the surface type before starting to select the abrasive medium that guarantees the removal of impurities without affecting the metal's nominal thickness. Whether you need to treat onshore metal structures or critical components on board, our technical team has the experience to apply this process safely and effectively.
The fundamental difference lies in the depth and efficiency of the cleaning. While manual sanding or mechanical wire brushing only remove surface corrosion and are extremely slow for large areas, blasting reaches total metal cleaning levels (such as SA 2.5 or SA 3 grade) in a fraction of the time. Furthermore, blasting is the only method that manages to create a controlled anchor profile (roughness) on the metal, something essential for modern industrial paint to have real mechanical adhesion. Other methods may remove paint, but rarely leave the surface ready to receive a high-durability anticorrosive scheme.
TECNAVAL Industrial Solutions S.A.S. can resolve this technical comparison by offering results that manual methods simply cannot achieve. Our processes are validated by international standards, guaranteeing that the anchor profile obtained is correct for the coating you plan to apply. This prevents you from having to repeat painting jobs prematurely due to adhesion failures. By choosing our solution, you invest in a process that ensures the longevity of your paint and the protection of your metal, leaving behind the inefficiencies of conventional, low-capacity cleaning methods.
This treatment prevents corrosion by absolutely eliminating all contaminants that accelerate the galvanic process, such as salts, oxides, and remnants of old paints that may be hidden in the metal's pores. By exposing the virgin metal and immediately applying a protective coating, the steel's contact with oxygen and ambient moisture, which are the direct causes of oxidation, is blocked. In addition, the created roughness profile allows the paint to penetrate deeply into the substrate, creating a waterproof seal that prevents corrosive agents from reaching the metal surface again during years of maritime exposure.
TECNAVAL Industrial Solutions S.A.S. can resolve corrosion prevention by integrating blasting with a strict anticorrosive paint application protocol. Our technicians are trained to measure environmental conditions (temperature and humidity) before starting, ensuring that the clean metal does not rust before the coating is applied. This care in waiting times and technical quality allows us to offer guarantees on our work. You obtain a surface armored against Cartagena's saline environment, minimizing costs for frequent corrective maintenance and maintaining the structural integrity of your vessels and equipment.
The cost of this service is variable and depends directly on factors such as the total surface area to be treated, the degree of existing corrosion, the geometric complexity of the structure, and the location where the work will be performed.
