What is a micron?
A micron is 1/1000th of a millimetre. It’s symbol is µ (Alt 230 or 0181 on a standard
How do I convert wet film thickness to dry film thickness?
Wet Film Thickness (µ) x Solids by Volume (%) = Dry Film Thickness (µ)
How do I convert dry film thickness to wet film thickness?
Dry Film Thickness (µ) x 100 = Wet Film Thickness (µ)
Solids by Volume (%)
What is the theoretical coverage of paint?
Solids by Volume (%) x 10 = Coverage (sqm/ltr)
Dry Film Thickness (µ)
How can I work out the amount of paint needed?
This calculation gives the theoretical requirement but this does not take into account
Area (sqm) x Dry Film Thickness (µ) = Litres Required
Solids by Volume (%) x 10
