Radius Gutter Installation Guidelines
To fit Radius or Straight Grp gutter plan your installation before commencing work. Grp gutter is supplied in approx. 2 metre lengths and should be handled with care to avoid splitting or shattering (CAUTION: this product is much more susceptible to damage & knocks than pvc equivalents).
HMRKN1 gutter brackets should be spaced at a maximum of 800 mm apart along each gutter. The gutter can either be used level (due to high flow rate) or to a 1:350 fall on long runs. Ideally space brackets to give an even support along each 2 metre run.
To install gutter brackets use at least 2 screws (ideally Zinc & Yellow or long life equivalents) to each support. Ensure all brackets are fitted flush against your fascia board, and either level or with a slight fall as listed above.
Fix all 2 metre Grp gutter sections by using Omniseal* to seal each joint. This should be applied to provide an overspill seal to avoid any possibility of leaks. Ideally apply sufficient to cause a slight overspill as each section is joined.
Stop ends and running outlets/unions do not have built in rubber seals, and these should be installed using bitumen based mastic with a slight overspill as above. Running outlets will need to situated above each downpipe, and care should be taken in drilling a hole & then cutting an appropriate aperture for the loose running outlets provided. Ensure a good seal to the outlet flange.
Use standard square 65mm downpipes or our HMRDS2 adaptor if a round downpipe is required.
Ensure all unions, outlets and stopends are watertight before dropping scaffold.
*Our Omniseal is a weatherproof pu adhesive which is suitable for all joints/unions. Standard colours are white & black. This adhesive can be painted where non-standard gutter colours are required. We cannot recommend normal silicones as these rely on a surface skin to create a seal; invariably this deteriorates with time & will eventually cause leakage.
Orac Technical & Installation Guidelines
An overview of Orac adhesive application is presented below. Fully detailed documentation is available on the Downloads page.
ORAC-FIX EXTRA is an extra strong filler for perfect joints that should be used to glue cornices and panel mouldings together. Abundant
ORAC Fix Extra may not be removed immediately (hardening approximately 3 hours).
DECOFIX PRO is a water based adhesive that creates a durable bonding between the mouldings and wall and/or ceiling. It can be also be
used as a filler to finish joints or defaults. Available in two handy sizes.
ORAC FIX EXTRA and ORAC DECOFIX PRO should not be painted until after hardening for a minimum of 1 day. Never stock or apply under 5°C.
