Regular storage tank painting is an effective way of preventing external and internal deterioration. Stainless steel tanks are susceptible to corrosion and polyethylene tanks need protection from UV degradation. Paint acts as a protective coating that extends the life of the tank and helps ensure its structural integrity. However, there is more to the process than just spraying on paint. It is necessary to prepare the surface, use the right materials, and follow safety procedures.

Industrial painting companies near me that specialize in painting the interior and exterior of storage tanks usually offer the full range of preparation services. This might be a simple high pressure washing to remove old paint and grime. Many painting companies use fully automated blasting systems with sand, steel shot, or dry ice pellets as the cleaning abrasive. The final plan for preparing the tanks takes into consideration specific conditions such as tank material, extent of deterioration, humidity, and temperature.

Epoxy is the most common coating for the interior of a storage tank. It is being upgraded continually, both in its ability to cure quickly and its resistance to chemicals. There are new polyurethane compounds that set in a few minutes, cure in only 48 hours, and are moisture resistant. These compounds can also be used on the exterior shell as can another new, moisture-cured polyurethane that can be applied even when there are high humidity levels. The storage tank painting company might also suggest acrylics, polyamides, silicones, enamel, and vinyl-ester.

Storage tank painting companies are aware of the procedures to follow for the safety of both its workers and anyone near the site. Proper ventilation is particularly important for painting the interior of the tank to reduce air borne toxins and solvents. Professionals use equipment to contain blast particulate and spray material from the painting. In addition, the workers all need proper gear including protective clothing, gloves, and masks.

There are certain efficiencies that reduce the cost of storage tank painting. Anything that can be done to shorten the number of days the tank is out of service is cost effective. This might include using coatings that cure quickly at the temperature of the time of work. It can also help to use equipment to control the heat and humidity inside and around the tank.

To ensure a successful project, it is important that professionals do the work. They not only have the proper equipment, they can advise on the best kind of preparation and paint or coating. Most importantly, they understand how to comply with all safety procedures and have the equipment to do so. Storage tank painting is a complicated job but one that is essential for making sure this huge piece of equipment will last for years.
