The primer value of
surfaces When building residential and non-residential premises, it is very important to use additional building materials, such as a primer. In addition to protecting metal and wood in the premises, a quick-drying compound is also used for vehicles, but the main area of its application is construction.
Practice shows that the additional protection provided by the primer helps to prevent rust formation, to keep repair for years to come.
Anticorrosive surface treatment is one of the mandatory conditions for high-quality repairs. Processing does not take much time, but the result can be seen over time - the buildings retain their original appearance, the iron structures are not subject to rust formation and corrosive changes.
Anticorrosive primer is a characteristic of
Thanks to a specially developed composition, which includes active chemical elements, the primer can penetrate into microcracks and form a protective layer. Its advantage is that it is very easy to apply, in order for the work to go right, you do not need to specially prepare the surface.
One coat of primer helps ensure a reliable grip of the surface with subsequent layers, be it paints or varnishes. When carrying out construction work, surface treatment with a primer is mandatory in the event that the structure or parts are exposed to sediments, and also experience temperature changes.
As a rule, anticorrosive primer is sold in iron cans, the volume of which can vary. The primer can be applied by a special roller, or by a spray, in the latter case the worker must ensure a reliable protection of the respiratory tract.
What do I need to know for successful work?
Depending on the composition, the primer should be diluted with water or simply stirred before applying to the surface. According to the test results, the primer dries at a temperature of +20 degrees for 45 hours under the condition of a single-layer application.
The normal application thickness is 18 to 23 μm. The primer provides protection of the surface from 2 to 5 years, after which the procedure can be repeated again without washing the old composition. The primer may have a gray or brown tinge, but on the surface it does not leave a colored trace and does not affect the color of the next layer of varnish or paint.
Before proceeding to the process, it is necessary to ensure the optimum room temperature, from work in the winter in the open air at temperatures below 0 degrees is better to abandon. According to the principle of priming, the composition penetrates into the surface layers, the process passes more actively at plus temperature.
The quality primer PF is manufactured in accordance with the standards, buying such a composition, you can be sure of its operation. If there are any crevices or voids on the surface, the primer is poured into them using a small brush or a small roller. The best option in this case is spraying the composition.
If the viscosity of the primer is too high, it can be diluted with water. Before applying the second layer, you need to make sure that the first one is completely dry. The drying time depends on the temperature indoors or outdoors. The work in the warm season passes, respectively, much faster.
