ASBESTOS ROOF COATING
This is Asbestoseal, the BBA Approved asbestos roof coating system from Liquasil Ltd.
Made in the UK, Asbestoseal is a system comprising a corrosion treatment for the metal fixings, a sealer for any cracks and holes and of course, the roof coating itself.
Here’s a quick video showing Asbestoseal being applied by roller to an asbestos roof by a Liquasil Approved Installer.
Asbestoseal Installation Procedure
The Asbestoseal system is designed specifically for industrial and commercial roofing application and is for professional use only.
Made specifically for asbestos roofs, the system completely encapsulates the asbestos cement substrate to provide a highly water resistant and water repellent surface, that is impervious to fungal growth, meaning an end to unsightly moss and lichen.
The first stage is to change any defective roof lights if defective. This helps reduce water ingress during the cleaning process.
Each of the metal fixings is then treated with Liquasil’s SWT Corrosion Primer, a wet and surface tolerant rust treatment that can be applied directly to wet rust.
Each of the fixings, together with any small holes and cracks are then sealed with Liquasil Non-Sag Sealer, a highly thixotropic silicone compound that adheres to the treated metal and the asbestos cement to form a permanent seal against water ingress.
One roofs with shallow pitches that are susceptible to wind-blown water ingress, we recommend that all overlaps to the roof sheets (vertical and horizontal) are sealed with Non-Sag Sealer.
The final stage of the installation is to apply Asbestoseal to the entire surface of the roof.
The BBA Certificate for Asbestoseal confirms a life expectancy in excess of 25 years, so you can be assured that this coating system is robust and fully tested and certificated.
EXAMPLE ASBESTOSEAL INSTALLATIONS
We have many examples of Asbestoseal installations, but here a few images of recently completed projects using this system.
Asbestoseal is available in any RAL colour.
TYPICAL COATING COST
Done properly, with the correct product, an asbestos roof coating will last many years.
Asbestoseal is the first asbestos roof coating to gain certification from the only independent UK construction materials inspection body, BBA (British Board of Agrément).
Budget around £35 per sq metre for an installation of up to 1000 sq metres, with costs possibly reducing for larger installations.
