Gutter Refurbishment DELCOTE® HPG is an elastomeric membrane, with vapour breathable properties suitable for application as a protective weatherproofing coating to completely coat the gutter surface. It has excellent elastic and flexible properties to withstand normal surface movements and is unaffected by UV or extremes of weather and temperature.
Key Properties:
Primer-less adhesion to
common products. Designed to
re-line metal, concrete and asbestos gutter and rainwater
systems. Used with SEAMSIL ® 300 gutter joint repair

DELCOTE® forms a tenacious, primerless bond to the
surface of steel substrate that prevents further oxidation


DELCOTE® is a silicone coating designed for re-coating roof and wall cladding substrate including masonry, concrete, asbestos cement, polyurethane foam and most painted or unpainted metals. It is the ideal product for reinstating a protective coating to profiled metal cladding where its standard 200 micron application will provide protection equal to or better than the original coating.
Key Benefits:

Primer-less adhesion to most Cladding Repair
substrates. Durability – proven
world-wide use with a life
expectancy of over 20 years
Used with SEAMSIL® 100 cut edge
corrosion repair. UV and
temperature resistant for longer
proven life.

Proven long term protection
against corrosion on metal roofs.
Provides breathable membrane
for protection of asbestos and
concrete surfaces.


UV makes coatings hard and brittle, limiting their ability to
expand and contract resulting in loss of adhesion.

DELCOTE® is completely and naturally resistant to sunlight
and UV radiation, ensuring enduring flexibility and adhesion.


SEAMSIL® is a unique flexible silicone remedial system
developed by Delvemade Limited in conjunction with GE
Silicones, part of the General Electric Company of EdgeSealingAmerica.
The system, initially developed to solve the problem of cut
edge corrosion on steel roofing has now become recognised as the most versatile and effective protection treatment in any situation where exposed metal is subjected to aggressive moisture conditions. For this reason, manufacturers across a variety of industries are specifying SEAMSIL® in the production of fabrications where resistance to corrosion damage is a requirement.

Key Benefits
Exceptional adhesion to cleaned and prepared surfaces and cure to provide a tough elastic seal, effectively encapsulating the damaged area to restrict further deterioration.
Proven long life, being unaffected by UV or extremes of
weather and temperature.
Excellent elastic and flexibility properties to withstand
normal surface movements.


DELCOTE® repels surface water, promoting flow and
discouraging the formation of ponding and standing water.


Delglaze is a high performance, high build, single
component moisture curing aliphatic polyurethane coating
that cures to provide a clear, tough membrane principally for
the re-coating and sealing of aged and weathered GRP
rooflights.Delgaze Roofing
Fully cured Delglaze provides a tough clear elastomericcoating with crack bridging capabilities that can also be used on a wide range of common building components such as concrete, glass, grp and ceramic tiling.

Delglaze is based on a unique blend of polyurethane resins to produce a coating, which provides a tough durable finish with a high degree of impact, erosion and weather resistant properties. Delglaze is simple and easy to use straight from the can by roller or brush application.
Key Benefits:

Primer-less adhesion to most common building products. Designed to recoat aged translucent rooflight systems,
including GRP, PVC and Polycarbonate. Fast application without disruption to internal activities. Provides ideal refurbishment solution for difficult to replace translucent sheets on asbestos cement roofs.
