Preparation work
Preparation is very important when painting your fibro or asbestos roof! First of all you will have to remove all down pipes. Next, you will need to clean down your roof with Mouldshield C diluted 5:1 with water, apply with a soft broom and wash off with hose water, do not use a pressure washer. Caution: By law Fibro or Asbestos roofs are not to be water blasted or cleaned excessively. Refix loose sheets with roofing screws. Repair any minor cracks and holes with Shieldcoat’s Roofbond Flexible Pointing.
Preparation coatings
If the valleys are lightly rusted, wire brush them down and apply a coat of Rustshield W. If they are heavily rusted then you will need to apply Rustseal and allow at least 24 hours drying time before applying your sealer coat. Apply a coat of Shieldseal W plus to the whole fibro or asbestos roof. If the condition of the roof is poor then you can apply one coat of Fillabond which will help to encapsulate all fibres to produce a better sheen level on top coat.
Finish coatings
Next, apply your two finish coats of ROOFBond Roofing paint to your fibro or asbestos roof, the colour of your choice.
Important Information
Remember, roof safety is very important and often overlooked by inexperience tradesmen or DIY. When doing roof restoration work and it is advisable to wear a respirator and use fall arrest equipment (safety harness/scaffolding).
Final word
After 7 days you can re fit the down pipes and the water you collect is safe for drinking.
