Site painting
All of our products are supplied in polyester powder coat paint finishes unless otherwise requested. We can supply some of our product ranges in mill finish but for further details and availability please contact our Technical Services Team on 01234 344108.
When site painting rainwater systems, it is recommended that all components are individually painted prior to installation to make sure all surfaces are uniformly coated.
Prior to painting either unpainted (mill finish) or polyester powder coated surfaces, clean components using a clean cloth and solvent cleaner, SC108. Prime mill finish surfaces with an “aluminium etch primer” or zinc phosphate; rub down polyester powder coated components with a light abrasive scotch (not steel) wool to achieve a good key.
Two-part synthetic or polyurethane paints are recommended for maximum durability. Ensure the paint is fully dry prior to contact with joint sealant. Partially dry paint may react with sealant, affecting reliability of gutter joint.
Handling & Storage
Gutters and pipes should be handled with care and should preferably be stored under cover on racks to prevent scratching or denting. All polyester powder coated gutter and pipe lengths are supplied in protective polythene sleeving and components packed in cardboard boxes.
If polyester powder coated products are stored outside, cover with a tarpaulin to guard against water ingress into the protective polythene tubing. If water becomes trapped within the polythene wrapping and left exposed to warm sunlight, it may leave permanent water stains on the paint finish.
Sealants should not be stored in temperatures below 0°C and kept away from any direct heat source.Solvent cleaners must be stored away from any direct heat or combustible source, preferably in an appropriate fire resistant storage cabinet.
Mill finished goods to be installed in their natural state should also be stored undercover, to prevent uneven oxidization to visible surfaces. Once installed the surface will mature uniformly.
Safety
The relevant safety regulations are outlined in the Health and Safety at Work Act 1974 and should be followed. Refer to The Approved Code of Practice (Design and Management) 2007.
Handling mill finished or polyester powder coated aluminium products does not pose any known health hazard, however it is recommended to wear protective gloves when handling mill finish aluminium.
Hazard instructions relating to sealant, solvent cleaner and touch up paint are printed on their respective containers and COSHH data sheets are available on the website.
Maintenance
Gutters should be periodically cleaned out and any built-up debris removed to maintain peak performance.
Check all fixings are secure and take any remedial action to rectify if necessary.
Leaf guards are available to fit each gutter system and are recommended for buildings close to trees, with restricted access, or areas susceptible to airborne debris.
To maximise the life of the decorative paint finishes, all parts should be washed down with clean water at least every 12 months. This period would be shortened to 6 months in a marine/aggressive environment.
