Primed or painted cast iron rainwater systems… Which will you choose?

Primed vs painted featured

Pre-painted cast iron is more expensive than primed cast iron, but the long-term cost benefits are substantial. Some things are worth paying a little extra for.

Properly protected and installed cast iron can last in excess of 100 years!

But all too often, primed systems that are painted on-site will suffer from premature exposure to the elements, and if water starts to attack the building, the cost of correction work will be massive when compared to the small initial investment in good cast iron protection.

Our stocked cast iron rainwater systems, treated with a certified three-coat system, factory-applied under strictly controlled conditions, last up to 10 years before needing to be repainted.

The factory-applied painting takes place in strictly controlled conditions which means that it is applied to a consistently high standard. It therefore consistently performs better and remains beautiful for years.

Primed or painted?

Priming and painting on-site is simply more difficult, several factors such as weather, skill, care of the painter and paint quality have a huge impact on the outcome.


Ask yourself these questions before you decide…

  • Are weather conditions suitable for on-site painting?
  • What is the quality of the paint and can you be sure all the coats will be applied on a busy site
  • Will all the coats be evenly applied, to the correct thickness?
  • Will the paint have sufficient drying time in the right environment?

The quality of installation and painting have a major impact on the lifetime and ongoing maintenance costs of rainwater systems.
