Finishes

Heritage Foundry® systems

Heritage Foundry products are manufactured by Heritage Foundry Ltd and supplied transit primed (Heritage) or pre-finished (Heritage Premier).

Heritage: transit primed

Transit primed products are supplied with one coat of protective red or grey oxide primer. This primer gives protection against corrosion during transportation and short-term undercover storage, and provides a suitable surface for a primer coat and final painting. On-site handling and painting are the responsibility of the contractor. Particular environmental considerations should be taken into account when choosing the paint system for the final finish.

Cast Iron Rainwater Limited recommend that an additional priming coat be applied on site, followed by 1 undercoat and 2 gloss coats of an alkyd paint system. All individual elements should receive the first gloss coat before fixing, and the final gloss coat after the installation is complete.

Heritage Premier: pre-finished

Pre-finished products use a three-coat system: one coat of base or transit primer, one coat of 2-part epoxy primer and a top coat. This system has been developed specifically for cast iron, to give a smooth and long-lasting finish. We offer the most comprehensive range of pre-finished traditional sand cast iron in the UK. It includes all components, such as union clips, stop ends, outlets, angles, brackets, pipe bands, branches, offsets, access pipes and shoes, plus rainwater heads and sockets: a complete, ready-to-install integrated system. All exposed surfaces must be treated in this way. It is advisable to take the paint finish inside collars and within the ends of rainwater pipes, to avoid the possibility of rust staining.

On-site handling

Cast iron can be cut and drilled on site with metalworking tools. Site-cut ends and drilled holes that expose bare metal must be de-burred and then repainted in line with our recommended site painting procedure. Sand cast iron is inherently strong and durable, but like all high-quality materials it must be handled and stored appropriately.

To avoid accidental damage to collars and spigots, store gutter and pipe sections horizontally, supported clear of the ground and preferably under cover. Pre-finished cast iron is supplied wrapped, to protect against physical damage during transportation and site handling.

Painted cast iron rainwater goods

An extensive range of painted black semi-gloss cast iron rainwater goods is available with a 48-hour lead time. The most used profiles are available: Half Round, Beaded Half Round, Deep Half Round, Victorian Ogee and Moulded Ogee guttering, and rainwater pipes in 2½”, 3” and 4” diameters.

As one of the UK's leading suppliers of cast iron rainwater systems, Heritage Foundry keeps track of industry changes that affect the everyday working methods of its colleagues in the building industry.

By removing the need for post-installation paintwork, Heritage Foundry painted cast iron offers up to a 60% saving on installation time and a 30% saving in materials. The durable 3-coat factory finish comprises 2 coats of primer and a top coat, which can last around 8 years before repainting is needed.
