Undercoat paints are liquid products containing pigments, functional fillers, and binder particles. The primary purposes of these products are reducing the coating porosity and improving the adhesion and the anticorrosion functions of the painted surface. Thus, the correct approach to painting involves the undercoat application for the bottom layer to preserve the top layers' protective and decorative properties.

Using Undercoat Paint for Walls 

Primer undercoat paint is suitable for preliminary surface preparation for topcoat applications, helping to decrease decorating materials' expenses. However, the main advantage of primer undercoat paint is that this product will save you from the frustrations of peeling wallpaper, paint, tiles, and other annoyances that come with finishing. Moreover, undercoat paints perform several functions related to the specifics of coating selection:

  • increase adhesion, which is especially important when working with glues and plasters;

  • strengthen and bind loose surfaces such as plastered walls;

  • reduce decorating paint consumption;

  • create an additional protective layer that guards against the effects of negative factors.

Wide Range of High-Quality Undercoat Paints

Before you start exploring available products, pay attention to the purpose of undercoat paints. Whether you need products for outdoor or indoor use or a versatile solution, you will easily find the right item in our catalogue. The undercoat paint is usually a colourless or white liquid, allowing the finish coat to be more attractive and bright. The choice of metal primer also depends on the conditions of use of the coating and the surface material:  

  • adhesive undercoat paint improves the adhesion of the surface that does not absorb moisture, such as glass, tiles, steel;

  • industrial primer for metal protects against corrosion and improves adhesion of metal, plastic, ceramics, and glass;

  • antiseptic products for the protection and treatment of wooden surfaces save coating from mould and mildew;

  • specialised undercoat paints to fill cracks and hide stubborn stains;

  • universal undercoat paint to reduce application time and the number of consumables.

Besides, Paints4Trade offers ready-to-use coloured undercoat paint that makes it easy to interact with large areas. You will also find a chlorinated rubber compound here, ideal for surface sealing and wet applications.

Industrial Metal Primer Paint for Long-Term Protection

Primer undercoat paint defines the protection level of the finish coating for metal surfaces. It contributes to the excellent adhesion of the protective layer and the painted buildings. Moreover, metal primer paint has another essential function – protection against corrosion and rust, provoking natural material destruction. The resulting layer also has to withstand heavy-duty loads to extend the lifespan of the painted object.

The right use of industrial primer for metal is essential to minimise cover breakdown. You can use specific galvanised undercoat paints or purchase all-in-one metal primer. Paints4Trade professionals are always ready to help you choose undercoat products, depending on individual needs and preferences. 

How to Paint Surface with Undercoat Paint for Metal

After choosing undercoat paints, you can proceed to surface treatment. Check the existing coating and remove it. Eliminate rust, grease, and other contaminants from the surface. Apply primer undercoat paint in a few thin layers using a roller, brush, or spray. Glossy finishes sometimes need extra abrasive processing for better adhesion to the topcoat. The drying time of undercoat paint for wall is several hours. Nevertheless, we recommend applying the overcoating layer after 16-24 hours for long-lasting results.
