Steel structures are durable, but their corrosion protection coatings require periodic renewal. Paint systems protect steel from rust and environmental conditions, but over time coatings age, crack and peel. Timely maintenance painting extends the structure’s service life by decades and prevents costly repairs.<\/p>\n
Maintenance painting is needed when:<\/p>\n
According to EN ISO 12944<\/a>, the service life of a coating system depends on the corrosion category (C1\u2013C5). In harsher conditions (C4\u2013C5), maintenance painting may be required every 7\u201310 years.<\/p>\n Before starting work, the structure is visually assessed and coating thickness measurements are taken where needed. Assessment follows EN ISO 4628, which defines coating damage levels.<\/p>\n Surface preparation is the most critical stage of maintenance painting. Depending on the extent of corrosion:<\/p>\n After cleaning, an anti-corrosion primer is applied to ensure good adhesion and provide chemical protection. The primer is selected to be compatible with the existing coating system.<\/p>\n The number of top coat layers depends on the specified dry film thickness (DFT) and environmental conditions. All paints used must meet EN ISO 12944 requirements for the applicable corrosion category.<\/p>\n Maintenance painting (spot repair + top coat renewal) is viable when the base coat is still in good condition and rust has not spread deeply. If the steel structure is heavily corroded, full surface preparation and complete paint system renewal is required. Starting maintenance painting at the right time is always more cost-effective than full structural restoration.<\/p>\n Steel Element O\u00dc offers maintenance painting of steel structures in Estonia and the surrounding region.
