Comprehensive repair of anti-corrosion coatings on steel structures and industrial installations

We carry out the work on site, usually on operational facilities, adjusting technologies and methods to the plant's working conditions.
When required due to technological reasons, we also offer the dismantling of components in need of repair and carry out the necessary work in a temporary workshop.
The rope access techniques we use eliminate the need for scaffolding or other costly solutions that often disrupt facility operations.
We carry out rope access work in accordance with the current safety standards of the IRATA system.

We operate professional spraying units and paint heating systems that significantly reduce thinner consumption, helping to cut costs and limit volatile organic compound (VOC) emissions.

By using Monti’s Bristle Blaster® technology, we are able to achieve surface cleanliness level Sa 2½ through mechanical methods, while minimizing the impact of the work on the surrounding environment.

This solution is particularly effective in situations where spot surface preparation to Sa 2½ is required, and abrasive blasting is either economically unjustified or impossible due to the risk of damaging existing equipment or installations.

QUALITY DOCUMENTATION

All work is documented in accordance with the current ISO 12944 standard (corrosion protection of steel structures) and the customer's specifications.

After completion of the work, we deliver quality documentation including:

Quality control reports
Reports on coating thickness measurements, climate measurements or other tests carried out
Declarations of conformity and certificates for the materials used
Photo documentation
Recommendations for further use and maintenance of coatings

QUALITY CONTROL

Each stage of our work is subject to systematic quality control by certified corrosion protection inspectors.

The process includes.:

Measurement of coating thickness (according to ISO 2808)
Testing of coating adhesion (according to ISO 4624 and ISO 16276)
Checking the cleanliness of the surface before application (according to ISO 8501-1)
Testing the roughness profile of the substrate (according to ISO 8503)
Measurement of coating application conditions (temperature, humidity, dew point – according to ISO 8502-4)
Tests for coating tightness and porosity (according to ISO 29601, ASTM D5162)

For quality control, we use professional measuring devices which are calibrated regularly. Our internal quality control procedures ensure full transparency of the work carried out and compliance with the accepted execution technology.

SURFACE PREPARATION

We use various methods for removing coatings and preparing surfaces, depending on the requirements and conditions of the work

Chemical coating removal agents – effective wherever the service has to have a minimal impact on the environment.
High-pressure washing – dust-free and spark-free removal of dirt and loose coatings with minimal equipment and logistics requirements
Mechanical processing with power or hand tools – used for local repairs or when the work must be carried out with minimal impact on the surroundings
Blast cleaning – complete removal of existing coatings and roughening of the substrate, which is particularly important for long-term corrosion protection
Blast cleaning in a water curtain – a solution that reduces dust and can often be used in areas with an explosive atmosphere

Depending on the method used to prepare the surface, the following degrees of surface cleaning can be achieved:

Using manual and mechanical processing – ST 2, ST 3
When using abrasive blasting – Sa 1, Sa 2, Sa 2 ½

COATING SYSTEMS

Depending on the characteristics of the surface, customer requirements and desired effect, we use:

High-temperature systems – resistant to extreme temperatures, used on components exposed to intense heat
Epoxy systems – with excellent chemical and mechanical resistance, ideal for use in aggressive environments
Epoxy-polyurethane systems – combining the durability of epoxy with the UV and weather resistance of polyurethane
Single-component systems – used in less demanding conditions and optimized for cost-efficiency

APPLICATION METHODS

Depending on the characteristics of the surface, customer requirements and the desired effect, we use:

Manual coating application (brushes, rollers) – often used in hard-to-reach places, small areas or complex shapes,
Airless spray – Ensures even coverage of large areas.

We provide services related to the renovation of coatings on such elements as tanks, silos, pipelines, fittings, pumps, motors, heat exchangers, chimneys, conveyors, boilers and all steel structures.

REPAIR OF CORROSION PROTECTION COATINGS

We provide corrosion protection for all corrosivity categories from C2 to CX in accordance with ISO 12944.
