Film Thickness per coat: DFT: 35 - 45μm
Spreading Capacity per Coat
The spreading capacity per coat depends on the film thickness applied, type of texture, surface porosity, surface imperfections, temperature, and wastage during painting.
On smooth plaster, the spread rate ranges from 9–11.5 m² per litre. Wood-floated plaster covers approximately 7–9 m² per litre. Concrete blocks have a spread rate of 4–6 m² per litre, while rough and textured plaster covers between 2–4 m² per litre.
Maximum spread rate per coat is obtained at minimum dry film thickness and vice versa.
