Before agreeing to a lease extension on these industrial premises, the tenant and landlord agreed to coat the roof using Liquasil’s metal roof coating system, Metalseal.
Survey, Specification & Enabling Works
Working closely with the Contract Administrator, Liquasil visited the site, conducted a thorough roof survey, and prepared a detailed, site-specific project specification.
D&D Industrial Coatings Ltd successfully tendered for the works and attended training with Liquasil to become approved installers.
Before starting the coating works, they carried out extensive enabling works before beginning the metal roof coating including;
- Installation of apron flashings to flues
- Replacement of ridge profile fillers
- Repairs to existing thermo-plastic gutter lining
- Replacement of defective fixings
Roof Coating Works
Cut edge corrosion had been treated historically, but this was now failing and needed replacement, particularly at the mid-lap joints which had been sealed with silicone and was trapping moisture.
The cut edge corrosion treatment was removed and the surfaces prepared back to ST3 standard before being primed with Liquasil SWT Primer.
Because the mid-lap joints had previously been sealed, they were sealed again, but this time with Liquasil’s HP Butyl Tape which is considerably stronger than silicone sealant.
The prepared cut edges of the roof sheets were then coated with Metalseal 20.
The final stage of the installation was to apply Metalseal 20 to the entire roof surface using airless spray equipment.
Three spraying teams were employed on the roof, each installing around 800-1000 sq metres per day. The total area of this metal roof coating project was a lottle over 10,000sq metres.
