Bridge coating not only enhances the aesthetic appeal of bridges, but it’s also important to prevent corrosion and rust for longevity. However, this painting and coating job is not easy, but there are various steps that can help achieve even paint coats.
Cleaning the Surface
Painting on a dirty bridge surface is one of the most common pitfalls. This is why you must ensure that the coating service in Dallas is cleaning the bridge’s surface from salt contaminants and other dirt particles to make sure the paint layer is even. In addition, it is important to comply with ISO 8502-9:2020 but make sure that the coating contractors are using water cleaning methods.
Dew Point Condensation
When the metal heats up, it is likely to sweat. In particular, the fluoropolymer paint tends to dilute and lose the adhesive quality if the bridge is coated after condensation has occurred. For this reason, the coating service in Dallas shouldn’t paint the bridge if the temperature is around 3-degrees Celsius as it’s the dew point.
This is why reputed coating services like 1 Priority Coating And Bridge Painting use a psychrometer to make sure there is no condensation.
Ineffective Intercoat Adhesion
Surface cleanliness is essential to achieve proper bridge coating. However, if the cleaning is not done properly, the contaminants can interfere with mechanical and chemical bonds that form the topcoat and base coat. For this reason, the exterior coat must be abraded to ensure the adhesion and bonding are on point.
