AsbestosSafe™ Primer Coating for the Encapsulation of Weathered Asbestos
"Treatment of asbestos-containing materials (ACM) with a sealant material that surrounds or embeds asbestos fibers in an adhesive matrix to prevent the release of fibers. A bridging encapsulant creates a membrane over the surface. A penetrating encapsulant penetrates the material and binds its components and any other unstable material together."
Asbestos Africa Heritage
Asbestos Africa is the leading South African specialists in Asbestos safety systems, giving high levels of success in the encapsulation field providing quality and innovative products to the commercial construction industry.
All Asbestos Africa products are specifically engineered to perform in conjunction with South Africa's construction materials and under the harsh South African environmental conditions.
Specifications
All project requirements and site conditions are unique. Asbestos Africa actively partners with customers to provide product and specification information individually suited for each job.
Customised product development, specifications, education, application, and on-site technical advice are just a few areas in which Asbestos Africa can support your project every step of the way.
Empowerment
Asbestos Africa is pioneering a drive across South Africa to assist communities that have been exposed to Asbestos for many decades. We have an initiative in place whereby the communities are being empowered to become fully accredited applicators with intensive training on asbestos, the encapsulation process as well as health and safety.
Job creation especially for women and school leavers alleviates the unemployment crisis currently on the ground in many communities.
Innovation
Asbestos Africa is at the forefront of technical advancement within the Asbestos Encapsulation Field. Our chemical Engineers continue to develop cutting-edge solutions for the Asbestos problems in Africa with Great success, raising the standards of consistency, performance and reliability.
Service and Support
Asbestos Africa customers are supported by a highly trained team of commercial business development professionals. Products are available nationally, with Provincial service centers located in Gauteng, KZN, Eastern Cape & Western Cape with large expansion on the cards.
Effect Of Coating On Reducing Roof Cavity Temperature
The Problem
Asbestos surfaces undergo a weathering process after many years of exposure and a loose surface layer develops which, on roofs becomes colonized with dark-coloured lichen. The lichen attacks the cement causing exposure of the Asbestos fibers. The surface becomes unstable and the Asbestos sheeting is weakened and the darkened color causes a substantial increase in roof cavity temperatures. The traditional process for coating Asbestos roofs was to clean the roof with high-pressure water to remove all lichen and loose Asbestos fibers. This procedure was eventually banned on health grounds, creating a need for a system that could be applied straight to the degraded Asbestos without disturbing the surface. The unstable nature of weathered Asbestos surfaces is a cause of some concern in the community and the AsbestosSafeTM System has been developed to minimize the danger of hazardous airborne fibres and provide an attractive durable finish.
The Solution
Years ago, Asbestos Africa addressed this problem and developed the AsbestosSafe System to achieve the following:
• The binding and encapsulation of Asbestos fibers
• Avoiding costly downtime associated with the replacement of asbestos roofs
• A significant reduction in roof cavity temperatures (up to 20 degrees) resulting in savings in building cooling costs
• An extension of the service life of asbestos structures
• A completely water-based and truly environmentally friendly system
• Provides a rejuvenated appearance in a range of decorative colours
The System
Through necessity and concern for the safety of our fellow people, Asbestos Africa developed AsbostosSafeTM primer. The primer soaks through the lichen and degraded Asbestos down to the sound base material, binding these unstable elements.
Application and Warranty
Recommended Application Procedure
An application with training and support from Asbestos Africa should undertake the following:
• An assessment of the state of the existing Asbestos
• Provide a specification to encapsulate the assessed Asbestos
• Application of the specified number of coats of AsbestosSafeTM primer
• An assessment of the complete binding of the Asbestos fibers by the Asbestos primer (future AsbestosSafeTM primer may be required)
• Application of the specified number of coats of AsbestosSafeTM topcoat
Warranty
The AsbestosSafeTM system of primer and topcoat will give many years of protection to all asbestos surfaces. When quality assurance procedures are followed and the asbestos safe is applied by an experienced applicator a certificate of compliance warranty may be issued ensuring the integrity of the system for a period of up to 7 years. A maintenance inspection must be undertaken every 2 years.
The Management and Control of Asbestos in the Workplace
It is the duty of care of the person with control of a premises to develop and implement a management plan. The purpose of an Asbestos management plan is to assist with the control of premises to comply with the Asbestos legislation and prevent exposure to airborne Asbestos fibers while Asbestos remains in the workplace. The ultimate goal should be to have all Asbestos materials removed from the site. Where removal is not viable, safety measures should be put in place to reduce the risk of Asbestos fibres by enclosure or encapsulation. The AsbestosSafeTM system provides building owners with a proven alternative to roof replacement that assists in addressing the duty and requirements relevant in each province.
Encapsulation using the AsbestosSafeTM system is both effective and an economic alternative to roof replacement.
