GIROMAX SOLUTION: Repair Substrate

Avoid costly replacement and prolong the life of your system by simply repairing the lining. A lot less hassle all round.


A roof gutter at eaves or central valley location forms the main component of a system which collects and diverts rainwater shed by the roof to protect a building’s foundation by channelling water away from its base. They also help to reduce erosion and protect painted surfaces by reducing exposure to water.

Rain gutters can be constructed from a variety of materials, including cast iron, lead, galvanised steel, copper, aluminium, PVC (and other plastics), concrete, asbestos cement and single-ply.

PROBLEM: Coating Failure

When UV exposure and surface moisture lead to fading, delamination, blistering or spot corrosion on coated steel sheet roofs the advice is often to replace. Avoid this costly and time-consuming task by instead preserving your existing metal sheeting.


The lifetime of a coated steel sheet may be defined as the time it takes to reach the stage where re-coating is necessary to preserve its performance or aesthetics. This can often be predicted using manufacturers’ projected performance data. Prime indicators are when the coating starts to fade, craze and/or delaminate or, on smooth finish coatings, when it starts to blister and spot corrode.


  • UV exposure makes paint hard and brittle limiting its ability to expand and contract with the substrate, affecting adhesion & causing it to delaminate

  • Moisture laying on the surface can penetrate a coating causing discolouration, lifting and corrosion on a steel substrate

  • Important pigments added for colour, UV stability etc. are lost through chalking, a natural self-cleaning process where paint literally wears away

The good news is that it’s usually the coating and not the sheet itself that needs replacing. Caught in time, most roofing and cladding can be treated and its protection indefinitely preserved. So if you’re looking for a metal roof repair solution, then GIROSIL® is the answer.

GIROSIL® is NEW generation silicone hybrid coating system for reinstating long-term protection to profiled metal sheets, benefitting from properties which can often provide better protection than the original coating for the following reasons:

  • GIROSIL® is highly UV resistant and temperature from -100oC to +250oC

  • GIROSIL® remains flexible and can easily accommode sheet movement

  • GIROSIL® repels water, preventing moisture from laying on the surface

  • GIROSIL® will not sacrificially erode

  • GIROSIL® is solvent free, releasing no VOC emmissions

  • GIROSIL® incorporates laminar flake, offering matchless corrosion control


GIROSIL® RC requires little preparation and provides 200 micron one coat protection at least comparable with Plastisol. GIROSIL® RC is applied as a system on roofs, to seal laps, bolts & cut edges. This, ensures that, unlike conventional coatings, the weakest details are equally protected.

Giromax Technology offers a specified product range that is installed by fully trained and experienced applicators, backed up with full technical support and assistance.
