Classical cast iron rainwater systems are supplied in a black primer coating or in ‘Plus’ finish (a semi-gloss, black topcoat) – available on Express and standard HR gutters and fittings and circular downpipes and fittings.

Painting – (on site, prior to installation)

When preparing the pipe, gutter and fittings for the on-site finishes, inspect the products, wire brush and touch up the factory applied primer coating, with a metal primer, (if and where necessary) after first ensuring all surfaces are degreased with thinners and are dust free.

Apply an undercoat (usually 2 coats), before finishing the product with a top coat to suit the building decor. We recommend that only a suitable, good quality paint finish is used to ensure minimal maintenance. Please note that extra care should be given where cast iron is being installed in exposed coastal areas.

Always consult paint manufacturer’s recommendations.

It is the responsibility of the installer/purchaser to examine and repair any coating damage to the factory applied primer coating, before applying further primer, and top coats prior to installation.

Classical Plus (Finish Coat)

Hambaker’s Classcial Plus rainwater range is supplied to site protected with a black primer coating ready for onsite painting. We recommend that an undercoat is applied (usually two coats) suitable for use with a water based primer before finishing the product with a good quality top coat to harmonize with the building dĂ©cor and ensure minimal maintenance.

Alternatively the products can be supplied pre painted with a factory applied high performance polymer alloy (PPA 571) in black semi-gloss for immediate installation. The coating has been tested to 1000 hours salt spray giving an expected life of up to 15 years subject to area conditions. For installations within a geographical location of 10km from the coastline we recommend that you purchase primer coated products for the installer to apply a suitable paint recommend by a paint manufacturer.
