What primer selected for perfect compatibility with the base ?

What is priming?

To begin with we shall understand, what is needed primer, and what constitutes the mixture.Primer consists of film-forming materials (glue, resin, oil), drying accelerators, pigments and other substances.A building compositions produced acrylic, mineral, alkyd based.

primer used to strengthen the surface (especially for the loose and weak bases), as well as for better grip and then finishing material (plaster, paint or wallpaper glue).And no matter your walls are made of metal, concrete or wood, they somehow have to be subjected to priming for further high quality painting works.

To determine which primer is best and what is right for you, you need to know the type of the base.For example, if you loose the foundation, it is better to buy a first coat of deep penetration (to strengthen), if the metal surfaces - the corrosion, and at the risk of moisture penetration - insulation compositions.More details below describe types of primers.

Types primers: for different surfaces

  • primer concrete is divided depending on the purpose of the concrete base (it is written on the package), it is often epoxy or polyurethane compounds.
  • Alkyd formulations used for wood (especially well suited for untreated wood) and metal surfaces.The only caveat - the mixture should not be applied to the plaster and plaster base.
  • Acrylic made of water-based, is used for almost all types of walls (particleboard, fiberboard, wood, brick, concrete, asbestos cement, plaster, foam).Not recommended for metal substrates (to prevent rust).
  • shellac mixture made on the basis of the milky juice of insects.Mainly used for wood (insulation knots).

Plus is also versatile primer , which can be applied to very different surfaces.It is a good primer and its use in cases where there was no or a mixture of the desired base to hand consists of several materials (brick and metal).

Types primers: for the desired effect

Depending on what is required for future surface, you can choose a variety of formulations for treatment.For example, in order to strengthen the weak and loose the walls (with crumbling plaster) to be applied primer deep penetration .It nourishes the base, making it more durable and reliable.

In the case where it is desirable to prevent the development of mold or mildew (in wet rooms) using a mixture of antiseptic .Their main effect is that they promote better adhesion (strong bonding material, and subsequent surface).The bond is so strong that the "infection" can not simply slip through the connection.

to protect the metal from rust corrosion use compositions.They are used not only for the pre-treatment of the walls during construction work, but also at home (with the appearance of rust on the pipes in the bathroom).Plus, for many drivers, it is simply irreplaceable in the garage.

We have listed the most popular compositions.There are, of course, and some other compounds, but they are chosen, one way or another, in the shop at the advice of experts.Therefore, if you have a question - how to choose the primer, - consider all the properties of your base and go to the store.

Primer consumption is always different for different surfaces.However, the average consumption is indicated on the packaging.There's also given instructions for use and safety precautions.Be careful!
