For future reference regarding paint consumption, also see attached correct calculations for Ume Guard and Uny Marine, please save the sheet for future applications.
VOLUME SOLIDS: Volume Solids of paint is the ratio of the non-volatile components present in it
to the total volume. Also termed as Solid Volume Ratio (SVR) or SV%. This is the most important
factor which determines the coverage of paint, others being thickness at which paint is applied,
nature of surface being painted, method of application etc.
DRY FILM THICKNESS (D.F.T.): The thickness of the paint film is measured in microns when
it is dry. An adequate film thickness is mandatory for the success of any coating system. Under
application will result in premature failure of the paint system. Exceeding the specified film
thickness can be equally dangerous. The recommended D.F.T. depends on the type of paint system
and nature of surface.
WET FILM THICKNESS (W.F.T.): The thickness of the wet film is measured in microns
immediately after application. Measuring W.F.T. is essential to keep the D.F.T. at the desired level,
by applying the paint at a pre-judged W.F.T; calculated by the following equation:-
WFT = DFT x 100
SVR
THEORETICAL PAINT CONSUMPTION:
Theoretical Paint Consumption (litres) = AREA (M2)
T.S.R.
Please also keep in mind:
That achieving the correct thicknesses of 50μ and 100μ is very challenging with a brush or roller and over application can lead to high stress in the coating cause premature failure.
For conventional spraying a loss factor may vary between 20%-40% and for Airless spraying 10-20%
You also need to take into consideration how many lengths of hose you will need as this has a big impact on the volume of thinners required to flush the lines.
Just let me know if you have any further questions I can help with.
