Asbestos Roofs:

 

Asbestos Roofing Recommendations for roofs that have heavy layers of Algae build-up:

It costs as much to remove the asbestos roofing as to replace it with a New roof.

Some 7 years ago we were asked to supply a quote to apply Solacoat to an asbestos roof in Ballina NSW.

Upon inspecting the roof we found it covered in mould. As pressure spraying is forbidden on asbestos roofing we applied a mould remover. This did not work. Our Engineer took a small sample of the asbestos to the Physics Department at the Southern Cross University in Lismore. They put it under their Electron microscope and found that it was algae not mould.

We then sprayed the roof with a mixture of copper sulphate and water. Mix 200 grams of copper sulphate to 1 litre of water. Spray the roof thoroughly and repeat again the next day.

Leave to dry - minimum of 2 days so as to allow the copper sulphate to kill the algae. Stir the same mixture into the Solacoat, i.e. at no more than 50ml per litre. This should ensure that any remaining algae will be killed.

Copper sulphate is available through most Rural Suppliers outlets.

 

NOTE:  Facial Masks should be used during the First application of our Solacoat Asbestos Primer.  The Product is not Hazardous, but uncoated Asbestos Fibres are.

The Process:

 

Having first attended to any Algai issues as per above, you can now apply Coolshield's new "Solacoat Absestos Primer", which eliminates the need to apply our Solacoat Clear Varnish Asbestos Sealer, unless you have some small cracks in the roofing. Our new Solacoat Asbestos Primer has excellent properties which inhibits any new growth of fungi & mould for a minimum period of five years, and kills any existing mould and fungi on the asbestos once applied. You require 2 x coats of the primer, and 2 x coats of our topcoats. The primer is also an excellent sealer.

We still provide our minimum 10 year warranty performance on our Solacoat Topcoats.
