Facade primer consumption

Priming of walls is an obligatory stage of work before painting walls, gluing wallpaper or finishing the facade. Some may think that priming the walls is a useless exercise, or rather, a waste of money. However, the primer has such a composition that allows the walls to get rid of dust, it fills all the existing pores, as a result, the wall ceases to absorb paint. To achieve this result, it is important to make the correct calculation of the primer consumption. If you make too weak a solution, then it will not fulfill its main purpose. In another case there will be a very large expense.

Application

After leveling the walls of the facade on the surface must be applied primer. The primer is applied with a brush. As a rule, it is diluted and make a concentrate. Dilute the primer with water. The ratio of water is measured according to the manufacturer's instructions.

Note! When working, it is important to protect your eyes. The primer solution can get into them, so you should be very careful.

The primer must be applied to the surface of the facade evenly. For greater effect, it is applied in two layers. Complete drying of the primer is achieved after four hours at a temperature of + 20 ° C.

Consumption

Primer requirements are high. It should have the following characteristics:

• color matching
• sufficient viscosity
• required covering ability.

Based on these indicators, you can accurately determine the consumption of the primer per 1 m². Primer consumption also depends on the nature of the facade surface, for example, some primers have established standards for consumption:

• Concrete Contact – 350 мл/м².
• Deep penetration primer - 0.1 kg / m².
• Decorative primer - 200 ml / m².

For example, the primer "Optimist", which is directly used for the facade has a flow rate of 250 ml / m².

Note! Primers do not emit any harmful chemical compounds and odors, so their use is safe for the environment.

Consumption некоторых грунтовок может отличаться, так как одни разбавляются в соотношении 1:2, а другие 1:5. Будет различаться и масса покрытия на один квадратный метр.

It is important to note that the final consumption of the primer for the facade may differ from the norm set by the manufacturer. Why? First, the flow will depend on the type of surface, since some surface will absorb more, and some less. Secondly, the expense will depend on the skill of the master. Some may carelessly use a primer, spilling it or applying an uneven layer. The specialist knows exactly how much primer must be applied to the surface of the facade. Moreover, today there are many tools that can minimize the consumption of this solution.
