To minimize the downtime during water tank painting, a common approach is to provide an environment that speeds up the process and lessens delay.
This can be through the use of a containment system wherein the temperature and humidity can be controlled. A ventilation component is added to the containment system to control air movement, which reduces dirt and contamination in the area.
Elevated water tank painting projects can cost facilities a huge amount of money, due mostly to the need to take the tank out of service. Water tank painting requires a dry surface to assure good coatings adhesion. But water condensation is inevitable given that the tank’s inner chamber is filled with water. To prevent coatings failure, water tank painting specialists have to drain the tank of its content and dry it completely before any coatings application can commence. The bottom line is that the water tank is out-of-service in the duration of the activity.
Recent developments in coatings technology provided another option that lessens the time and money spent in water tank painting projects. Moisture-cured urethane coatings can be applied to tank surfaces without having to drain them of their content.
The effective application of moisture-cured coatings have made it possible for in-service tank painting, particularly of water tanks for major industrial, commercial and community facilities.
Moisture-cured coatings possess a unique chemistry suitable for water tank painting — they dry quickly, apply easily, and are not vulnerable to failure in the presence of humidity-born hydrogen components.
