Not all roof coating colours are the same

It might be surprising to some but there are actually more colours available for roof coatings than just grey. Seamsil by HD Sharman boasts a wide range of colours to choose from. We use this system on many of our projects and we highly recommend it. The coating system colour chart compliments branding and design specifications while its performance is outstanding.

What is Delcote?

Delcote is an advanced full roof coating system. Its a remedial system designed to enhance and protect steel roof sheets. There are two Delcote full overpaint options; Delcote 10 and Delcote 25.

What is the difference between Delcote 10 and Delcote 25?

Delcote 10 is a single coat system providing a 10 year guarantee. Its more suitable for short tenancy agreements and has a reduced application time. Delcote 25 is two coat system providing a 25 year guarantee. Its preferred by owners who require a long term solution to steel roof protection.

Combined with Seamsil, Delcote provides market leading reliability and faster application times. Delcote is an inorganic coating with excellent resistance to UV, rain, snow and temperature extremes. Delcote offers high movement accommodation, flexibility and adhesion without cracking, peeling or chalking.

Features and benefits

  • Proven long term protection against corrosion on metal roofs.
  • Delcote is a 100% silicone based remedial treatment and is suitable for use in areas of industrial pollution and/ or coastal and marine environments.
  • Primer-less adhesion to most common substrates.
  • Fast cure rate, 15–30-minute skin over time followed by 1–2 hour tack free time.
  • High static viscosity ensures material stays where it is sprayed. It will not flow off high spots or vertical areas and therefore allows for easy build-up of required dry film thickness.
  • Long service life with high resistance to UV attack.
  • Provides breathable membrane for protection of asbestos and concrete surfaces.
  • Does not degrade by chalking.
  • Any subsequent soiling of the product can be easily removed by a simple detergent wash.
  • No additional structural weight is applied.
  • No risk of further penetrations.
  • Delcote needs no vapour control. It is a fully breathable membrane which can further seal the roof from air leakage, helping to retain heat.
  • No disruption for building users.
  • Ease of application – roller, brush or airless spray.
  • High solids helps prevent Sag.
