Coastal Paint Finishes for Cast Iron Guttering
The Durability of paint systems is not an exact science, neither is the predictability of atmospheric conditions to which a product will be exposed. Prevailing winds may carry airborne contaminants (e.g. seaspray from the coast) predominantly on to one face of a structure.
Areas falling within a coastal /marine environment are classified as a C4 corrosion category. The conditions in these areas are more aggressive than those experienced in many other areas due to the prevalence of airborne water and salt particles. If these water and salt particles can form an electrolyte on the painted finish, any exposed or damaged areas of the painted finish will begin to corrode the Iron substrate at an increased rate compared to an inland location.
Protecting Coastal Ironwork – Paint Finishes for Coastal and Marine Environments
Coastal and Marine environments provide a challenging environment for metalwork on period buildings, and metalwork not properly protected will deteriorate at a rapid rate.
To combat this aggressive environment, specialist paints with an overall coating thickness, need to be much greater. This increased coating thickness forms a longer-lasting barrier between the environment and the substrate thus delaying the onset of corrosion.
Maintaining Cast Iron Gutter in Coastal Locations
A robust maintenance regime must be put in place to ensure that no salt or other contaminants can build up on the surface of the coating. Irrespective of the volume and quality of coating applied, regular maintenance and repainting will be required to ensure your Cast Iron products can continue to combat the harsh environments that coastal conditions present.
Coastal Paint Finish for Cast Iron Guttering
For guidance, coastal areas are estimated to be areas within 5km (approximately 3 miles) of the coast. Areas falling within a coastal or marine environment are classified as a C4 corrosion category.
Marine Paint Finishes for Coastal Guttering
The durability of paint systems is not an exact science, neither is the predictability of atmospheric conditions to which a product will be exposed. For this reason, we are unable to be very specific regarding the number of years the paint will last. To combat this aggressive environment, our paint system finishes for marine environments have been developed over many years to ensure a quality and long-lasting finish.
Marine Paint Finish Specification for Cast Iron Guttering
Marine and Coastal paint finish specifications can be offered on all rainwater products and the Hertitage express (TX) soil system. Black painted or RAL and BS colours are also available to this specification.
Coastal Guttering Repairs and Maintenance – Site Survey
It is imperative that a robust maintenance regime is put in place to ensure that no salt or other contaminants can build up on the surface of the coating. Irrespective of the volume and quality of coating applied,regular maintenance and repainting will be required to ensure your

Standard Paint Finishes for Cast Iron Gutters and Pipes
The main functions of a primer are to provide short-term protection and provide a surface to which a subsequent top coat or finish coat can adhere. Our Bital 404 primer paints used are RAL 7024 dark grey in colour and have been specially formulated to create a barrier to corrosion. The primer can be over-coated with epoxy, polyurethane or acrylic paints.
Primed products are coated internally and externally. This primer is a transit coat to provide short-term protection during delivery and storage undercover.
Black painted products supplied have an exterior coating, high solids and a black gloss paint finish. High solids and a gloss finish ensure a greater durability over lower solids and matt/satin finishes. The paint application is carried out in a controlled environment located on site. All black-painted products arrive individually bagged for maximum protection and are ready for immediate installation. We also offer and recommend purchasing touch-up paint (XP0007 – 250ml tin) with all painted orders, this can be applied to installation scuffs, scratches or cut ends. This paint specification finish meets a C3 corrosion category environment.
RAL or BS (British Standard) Colours
Our bespoke paint service is available for all of our cast iron rainwater products (gutters, pipes and hoppers) and the Heritage Express cast iron soil systems. Tuscan Foundry, are able to offer products in any RAL or BS colour, this is a finished top coat (full gloss) and is supplied ready for installation. All RAL or BS painted orders will also be supplied with a matching touch-up paint. All bespoke painted products will arrive individually bagged for maximum protection. This paint specification finish meets a C3 corrosion category environment.
We are also to offer a factory colour match service. Colour identification can be taken from an existing casting or paint swatch.
