Theoretical spreading rate per 1m2:
Indicates the amount of m2 that can be painted from one kilogram (m2 / kg) or one litre (m2 / l) of paint at zero losses and on an ideally smooth surface at the specified coating thickness.
Application losses when applying a coating:
Loss is the amount of paint that does not fall on the surface of material when the paint is applied. When calculating the real paint consumption for a given area, we use the method of application and the material on to which the paint will be applied. When applied by brush, or with a roller onto a smooth surface is the loss calculated is approx. 15-20%. With high pressure and airless spraying on a homogeneous smooth surface, a loss of 30-40% is normally expected. When spraying on a rugged surface (grilles, railings, structurally complex parts), depending on the complexity of the component and the spraying technique, it is necessary to calculate a loss rate of about 60-100%, since the spray gun beam often oversprays the material. In the case of application “from all sides”, the loss is multiplied proportionally.
Dead-coat:
is the amount of paint needed to fill a rough substrate that has been created by surface blasting. In the case where a DFT is specified, this is the thickness needed to be achieved regardless of the roughness of the substrate. Therefore, in order to determine the actual consumption of the coating material for a given area, it is necessary to calculate the amount of coating needed to level the area to level 0 combined with application losses when calculating. In the case of blasting to Sa 2.5, the average paint consumption for topping up this area is about 30-40 μm.
Recommended layer thickness
It indicates the maximum layer thickness applicable to a specific surface of a coating on a vertical surface in one operation. Exceeding the maximum thicknesses recommended by the manufacturer may result in significantly longer curing of the coating system. If exceeded, the coating may become inconsistent. Paint “Falls off”, respectively it can tear off.
Content of non-flowing components (dry matter) in % by volume:
Indicates the volume of coating remaining after application of the paint on the substrate after the paint has been completely cured under the prescribed conditions
The VOC or liquid organic substance
is any organic liquid that spontaneously evaporates at normal atmospheric temperature and pressure and has a boiling point below 250 ° C.
Calculation of the Steel Structure Area:
Depending on the profiles approx. 35-45 m2 per 1 ton of steel.
