The importance of priming before painting

09 agosto 2022

Priming is a vitally important step prior to paint application. The difference between a pre-primed finish and a surface where the paint has been directly applied is not only noticeable in the result, but also in the strength and durability of the paint. It is the difference between a good result and an excellent result.

Primer is a coating that prepares the surface for subsequent painting. Its function is to seal the pores of the surfaces and provide the substrate with greater adhesion. 

Advantages of applying a primer before painting 

Priming before painting does not have to be time-consuming or costly and has great advantages, whether you are a professional or undertaking a DIY project at home:

  • It reduces paint consumption, as fewer coats will be needed to ensure an excellent result.
  • It allows you to change the colour of the decoration of any surface. If you wish to change from a dark colour to a lighter one which provides more luminosity, the primer will facilitate this process, resulting in a uniform finish without irregularities in the colour.
  • It adheres better to the substrate, allowing the paint and colour to remain good-as-new for much longer.
  • It prevents the appearance of possible issues such as humidity, condensation or oxidation on surfaces exposed to the elements.

Types of primers 

There are a wide variety of primers with different functionalities, but like topcoats, primers can be divided into the following types:

Water-based primers: these are water-based, fast-drying, non-flammable and virtually odourless. Moreover, they are environmentally friendly coatings.

Synthetic primers: these are solvent-based and consist of synthetic resins. They have a stronger odour.

However, the most important thing when choosing a primer type is to take into account the nature of the substrate and the capabilities required.

Universal Primer 

Pinturas MONTÓ offers a universal primer that’s suitable for most surfaces and very easy to use:

Montoprimer total acqua: this universal, water-based, multi-adhesive, single-component primer suits most substrates. It's rustproof, fast-drying and can be repainted with plastic paints, enamels, polyurethanes, epoxies, etc.

Montoprimer total: this universal synthetic, multi-adhesive, single-component primer suits most substrates. It’s also rustproof, fast-drying and can be repainted with plastic paints, enamels, polyurethanes, epoxies, etc.

Metal primer 

Impripol: A dual-component, white polyurethane anticorrosive primer that adheres very well to metal. Ideal for demanding applications such as marine environments or galvanised surfaces and structures.

IMPRIEPOX M-10: a dual-component white epoxy anticorrosive primer that adheres very well to metal and other substrates such as polyester.

Imprimación sintética: an anticorrosive primer based on alkyd resins. Fast air drying.

Façade primer

To ensure maximum durability and to protect façades from the appearance of issues such as damp or saltpetre, it is advisable to use a façade primer:

Fijamont: a solvent-based fixative primer that guarantees maximum penetration on porous, painted or newly constructed surfaces. It is an anti-humidity product with maximum adherence that avoids salts and glazes.

Fijamont acqua: this is also a water-based fixing primer for façades, which offers maximum adhesion and penetration and prevents the appearance of damp and saltpetre.


Floor primer 

Imprimación Epoxi Suelos: a clear, water-based product for application on a wide variety of substrates, based on epoxy resin and modified polyamide. It is designed to act as a bridge between difficult-to-bond substrates and other finishing products.
