By buying any paintwork material, you can quickly calculate the required quantity, as the manufacturer indicates all the necessary information on the packaging. But, it is worth noting that the volume will be individual for each type of surface. Only professionals can make an accurate calculation and calculate paint consumption rates for metal. Detailed information can be found in the article below.
To carry out independent calculations on the amount of paint used for metal, it is necessary to pay attention to such important factors:
You should also pay attention to another series of indicators, from which paint consumption will depend on. It is primarily about the hiding power of the composition, which is most often expressed in g / m 2 . This indicator will indicate how much paintwork material can cover the previous layer. Most modern products are able to give the desired result in the first layer of staining, the maximum - the second.
An important in this question is the instrument itself, which is used for staining. Cost-effective and even paint application to metal can be ensured by a properly selected brush. The ideal option for most types of paints should be called a brush with natural bristles. But for paints and varnishes on a water-dispersed basis, it is not suitable. What criteria influence the quality of the staining instrument?
Choose the right brush
Coverage of the composition is inversely proportional to the consumption rate.
The item to be painted can be made of different metals, for example, colored, black or galvanized iron. This parameter is especially important when using oil and alkyd substances. The condition of the surface also matters: a smooth and even surface with no obvious signs of deformation will automatically increase the quality of coloring.
Note a few more important points:
Consumption depends on the color
When using the spray guns, a measuring jar is purchased, through which to determine the volume of matter per 1 m 2 will be much easier.
To reduce consumption, the surface is pre-primed or puttied. This will avoid dripping and uneven application of the layer.
In closed rooms, consumption is less than
Not worth forget that when working you should also take into account possible loss of paintwork material, which will also affect the amount of paint needed. For convenience, you can use such average indicators depending on the place where the dyeing is carried out:
Assortment of paints
When choosing paintwork material for painting a metal surface should pay attention only to two large groups:
The latter are leaders, since they have a greater number of advantages:
For carrying out internal coloring choose acrylic structures as they are safer for health and have no caustic smell. If you need to carry out outdoor work, you can opt for enamels.
Alkyd paints withstand a temperature of not more than 80º C. While for acrylic types this figure reaches 120º C.
Assortment of paints by metal, presented in specialized stores, is wide, but three brands lead.
Pay attention to the figures that the manufacturer indicates, but do not forget about the factors that affect the consumption.
Dyeing should be carried out in accordance with the technology, otherwise you can get a poor-quality coating with drips and gaps.
