Paint consumption rates for metal

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.

Consider the factors

To carry out independent calculations on the amount of paint used for metal, it is necessary to pay attention to such important factors:

  • quality of the coloring matter;
  • surface condition;
  • dyeing technology;
  • air temperature and humidity;
  • drafts or air currents;
  • other nuances.

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?

  1. Wide grip.
  2. Good thickness.
  3. Lack of a winding on a nylon basis.

Coverage of the composition is inversely proportional to the consumption rate.

Paint consumption parameters

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:

  1. Base color: to obtain light shades without gaps, you will need to paint in several layers. For example, on average the consumption rate per 1m 2 of white color is about 110 grams. and black - 60 gr.
  2. Method of application: the spray gun is the most economical and evenly distributed, but not suitable for every type of substance. When using a brush and a roller, the volume of consumption will be several times larger, and leakage may also occur.

Paint consumption rates for metal 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.

Losses

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:

  • up to 5% - in the open air with no wind;
  • 5% - in closed rooms;
  • 20% - in windy weather.

Assortment of paints for metal

Paint consumption rates for metal Assortment of paints

When choosing paintwork material for painting a metal surface should pay attention only to two large groups:

  1. Alkyd paints. In turn, there is a division into two subgroups - these are oil compositions (their base is linseed oil) and enamel.
  2. Acrylic Coatings.

The latter are leaders, since they have a greater number of advantages:

  • the applied layer is strong and durable;
  • do not fade or deform for a long time;
  • corrosion protection is present;
  • able to withstand high temperatures;
  • environmentally friendly and non-flammable.

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.

Popular brands of paints

Paint consumption rates for metal Popular paint

Assortment of paints by metal, presented in specialized stores, is wide, but three brands lead.

  1. Tikkurila. It has good wear resistance and perfectly tolerates the effects of all types of fats and oils. Designed for both internal and external works. In the first case, 1 l will be enough for coloring 8-10 m 2 , and in the second - 10-14 m 2 .
  2. Hamerayt. The difference is the possibility of painting surfaces with rust without prior priming and cleaning. 1 l of paint in 1 layer will cover 8-9 m 2 .
  3. Novbytchim. Modern primer enamel. In addition to the decorative features, the coating will create a protective layer. At 1 m 2 in 1 layer you will need from 80 to 120 ml.

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.
