Systems and support for your roofing jobs
Found cut edge corrosion on a job? The systems, the specification and the technical backing to price it and put it right.
Certified systems
Four liquid-applied systems, from treating the laps and eaves to coating the whole roof.
A specification for the job
Written for the roof in front of you, so the job is priced and installed with the right system.
Technical support
Answers from the technical team before and during the job, with a site visit where the roof needs one.
Surveys and reports
A survey and condition report to back up your quote, with drone surveys and moisture mapping where the job needs them.
Trade accounts
Buy the systems direct, with pro-forma for the first orders and 30-day terms once the account is approved.
A guarantee behind your work
Installations by contractors in the network are guaranteed through Basecare, materials and workmanship together.
Certified liquid-applied systems
Four systems, two for treating cut edge corrosion where the sheets are sound and two for coating the whole roof, all applied from the roof.
STPSilane terminated polymer
Cut edge corrosionA single-component sealant that bonds to plastisol, PVDF and bare galvanised steel alike, cures in damp conditions, and stays flexible as the sheets move with the weather. It is worked into the cut and along the lap as a bead, then coated over, so the cut is sealed against moisture and the corrosion underneath it stops.
- Used for
- Eaves, end laps, verges and the cuts around rooflights and vents
- Applied by
- Brush and knife, from the roof
- Cures
- Moisture curing, in damp conditions
- Finish
- Coated over with the treatment system in the roof colour
- Specify when
- A rust line at the cut, with the sheets still sound
PolyurethaneReinforced repair system
Cut edge corrosionWhere the coating has pulled back from the cut and the steel is corroding, the cut needs more than a seal. The polyurethane system builds a reinforced band over the cut and a hand's width of sheet either side, encapsulating it so it cannot lift again. Tough enough for foot traffic along the lap and flexible enough to move with the roof.
- Used for
- Advanced stage corrosion, gutter lines and heavily corroded laps
- Applied by
- Brush and roller, with reinforcement where the cut needs it
- Cures
- Single component, cures to a hard flexible film
- Finish
- Colour matched to the roof
- Specify when
- Coating lifting back from the cuts, with staining down the sheets
Hybrid polymerSpray roof coating
Whole roofsOnce the factory coating on the sheets is failing, the cuts are sealed first and the whole roof is spray coated in one continuous film. The hybrid polymer system covers every lap, fixing and profile without a seam, renews the surface of the roof and gives it one guarantee from ridge to eaves.
- Used for
- Full roof coating over prepared and sealed sheets
- Applied by
- Airless spray
- Cures
- Single component, air curing
- Finish
- Matt or satin, colour matched or changed
- Specify when
- The factory coating is failing across the sheets, not only at the cuts
PolyureaFast-cure spray coating
Whole roofsA two-component spray system that cures within minutes of application, so a roof can be coated and back in service the same day, and rain later that afternoon does no harm. The hardest wearing finish in the range, for roofs with heavy foot traffic, plant, or an exposed position.
- Used for
- Full roof coating where speed of cure or wear resistance matters
- Applied by
- Heated plural component spray
- Cures
- Within minutes of application
- Finish
- Colour matched or changed
- Specify when
- The roof has to be back in service quickly, or takes foot traffic and plant
