How to properly dilute the primer and what is needed for this
Most primer mixes are sold ready-made form for application. It will be enough to stir the composition well and it will be possible to apply it to the processing surface. But how to dilute the concentrate primer?
You will learn this later, but one thing is for sure - you cannot use the product undiluted. A number of products are presented in the form of a dry soil agent, which must be diluted before starting work. How and how can this be done? To answer this question, you will first need to know the composition of the mixture, and what specific solvent (that is, a diluent) is important to use to perform the work.
For example, a water-dispersion mixture, as a rule, must be diluted with clean cool water. In other cases, a certain organic solvent is used. The choice of diluent may also depend on the type of base. By the way, to work on very porous types of surfaces, the concentrate is practically never diluted.
So, what is it for?
Now consider what is important to use as a dilution agent.
Primers can be distinguished by their properties, composition, and also the method of application. Moreover, they can all be divided into two types - increasing adhesion (that is, adhesion) and strengthening.
Acrylic concentrates can be diluted with water. The substance is non-toxic, odorless. Acrylic can be an adhesion type primer, and even deep penetration.
It is used under enamel and for work on metal surfaces.
But it is not recommended to use it for wall surfaces made of concrete, stone and other types of minerals. This will include anti-corrosive alkyd compounds with a rust modifier. The concentrate can be reduced with similar organic solvents as in the mixture, or white alcohol, solvent, xylene and their mixtures are used.
Separate mixtures are also intended for work on metal (against corrosion) with further enamel coating. The primer can be diluted with xylene (5 to 10% of the total volume) with further enamel coating. This is necessary to simplify application and increase the time for the start of polymerization.
It will be safest to use the product in the intermediate finishing of external building walls.
Priming of metal structures in several layers is obligatory under enamel, painting or in conditions of constant moisture. These are insulating agents that protect against moisture and rust - glyphthalic and phenol-formaldehyde compounds. They help form a strong and waterproof film. There are also protective (that is, passivating), which make iron immune to the effects of negative environments, namely, increases its isolation. And the third type is converting, which convert rust into a difficult-to-dissolve or rapidly disintegrating compound, and also increase the adhesion properties of materials
The primer mixture, which is diluted, lays down much better and sets faster.
And, nevertheless, deeply penetrating compounds show themselves better in undiluted form.
Experts strongly recommend that when carrying out intermediate construction, as well as repair work, priming is mandatory. In turn, the manufacturers of construction types of mixtures took care that customers could use the material without any problems, providing the packaging with instructions for use.
