How do I apply Ceratech to smaller areas?

Application to smaller areas is simple and straight-forward. All the rules that apply to painting a normal roof apply to Ceratech, except that each coat is applied at twice the normal thickness to achieve a coverage rate of 500 µm - ½ mm. When preparing the surface to be painted, besides removing all dirt and loose paint by wire-brushing or high pressure water blasting, it is advisable to kill off all fungus spores by washing with a bleach solution (sodium hypochlorite) - buy in bulk from your local industrial chemicals supplier.

Do I need a primer?

Applying a primer is recommended in most cases - the primer vastly improves the life-expectancy of the coating.
For IBR or corrugated iron, abrade red-rust spots to bright metal and apply a rust-converting primer. Prime entire surface with a galvanised-iron primer. Asbestos and cement-based tiles should be primed with a bonding primer. Polycarbonate sheeting should be thoroughly abraded. No primer required.

What are the best times of day for application?

Apply CERATECH only on a warm, dry day for best results. Wait until after 10am if there is any sign of dew.
Do not apply after 4pm.

How thick should the coating be?

CERATECH is a barrier and therefore the film thickness is important. It is better to go on thicker. Spreading it too
thinly defeats the purpose of the the application. See our Coverage Calculation page.
