Roof Coat

Sissons Roofcoat is recommended for the protection and decoration of all unglazed, cementitous roof tiles, such as asbestos, cement cladding or other cement-composite roofing, where conditions demand better performance than that offered by conventional emulsion paints. This weather resistant paint dries to an exceedingly tough, lightfast ad durable film, yet remains sufficiently flexible to withstand the effects of climatic and temperature variations It is also highly resistant to alkali attack and algae or fungal growth.



Surface preparation should be properly carried out before application. All loose, flaking, chalking or friable materials should be removed. Make good any defects and ensure that the substrate is clean and free from contaminants, such as oil, grease, grime and fungal growth.

For new surfaces, ensure that the substrate is sufficiently dry (below 16% moisture) prior to paint application.

For redecoration, ensure that the previous coating is in good condition, otherwise remove via water-jet and/or scraping then treat as per new surface.

Unglazed tiles /Cement cladding /Cement composite (New / Redecoration)

If the substrate colour is uneven, or in the case of re-decoration there is a radical change in colour, an additional coat of finishing may be required



Theoretical Coverage Up to 14.2 square meters per litre per coat

Expected Practical Coverage

Based on 25% Loss Factor

Up to 10.7 square meters per litre per coat

Actual spreading rate will vary due to factors such as method and condition of application e.g. surface profile or roughness.
