Types of surfaces for spray painting
In spray painting, the choice of paint or lacquer depends heavily on the surface. Each surface – whether wood, MDF, metal, plastic or stone/concrete – has specific properties that determine which primer, pre-treatment and lacquer must be used. A wrong combination leads to poor adhesion, premature wear or aesthetic defects.
Correctly identifying the surface and applying the correct spraying technique and materials is therefore essential for a durable and even result.
Features
- Material-dependent: every substrate requires customized primers and coatings.
- Influence on adhesion: porous substrates such as MDF or concrete require more preparation.
- Durability: hard substrates such as metal and plastic often require extra protective layers.
- Risks: incorrect choice can lead to blistering, rust or discoloration.
- Furniture (wood, MDF, veneer).

Conclusion
The type of substrate determines the approach to spraying. Each substrate has specific requirements for preparation, primer, and paint selection. Wood and MDF require careful treatment against absorption, metal requires rust protection, plastic requires a special adhesion primer, and concrete or plaster must be fixed.
An incorrect approach leads to poor adhesion and high repair costs. Professional companies have the right knowledge and materials to treat each type of substrate correctly. Via jeofferte.nl clients can easily compare quotes and choose the right specialist for their specific project.
Primers and undercoats for spray work
A good spray finish starts with the right pre-treatment. Primers and undercoats form the connecting layer between the substrate and the final coat of paint. They ensure better adhesion, an even coverage and extra protection against external influences.
The type of primer or undercoat depends on the substrate (wood, MDF, metal, plastic, concrete/gypsum). Skipping or incorrectly applying this layer is one of the most common causes of poor adhesion and premature wear of spray work.

Price and quality differences in spray painting
The price and quality of spray work are determined by an interplay of factors: the chosen type of paint, the finish, the substrate, and especially the method of application. For consumers and professionals, it is often difficult to assess why one quote is significantly cheaper or more expensive than another.
This overview explains the main price and quality differences, enabling clients to make informed choices and understand which investment leads to the best balance between cost, durability, and aesthetics.
Features that affect price and quality
- Type of varnish or coating – PU varnish is more expensive but more durable than acrylic; epoxy is suitable for heavy industrial use.
- Gloss level and finish – High gloss and special effects (metallic, soft-touch) are pricier than standard satin gloss.
- Preparation – Sanding, priming, and dust-free work determine the lifespan and the smooth final result.
- Layer thickness and number of coats – Multiple thin coats increase quality but also costs.
- Application method – professional spraying in a spray booth is more expensive than brush or roller, but it provides a much more even result.
- Labor hours and experience – skilled sprayers work more efficiently and generally deliver higher quality.
Applications and price differences
- Kitchens: a complete kitchen in satin-finish PU lacquer is more expensive than the same kitchen in water-based acrylic, but much more scratch- and stain-resistant.
- Furniture: soft-touch or high-gloss finishes are more labor-intensive and therefore more expensive.
- Industry: powder coating is more expensive in installation costs, but often cheaper per part for large series.
- Walls/ceilings: sprayed acrylic paint is cheaper but less wear-resistant than 2K PU systems.
- Often 1K acrylic or alkyd paints.
- Low VOC content and easy to process.
- Less wear-resistant and more sensitive to scratches and chemicals.
- Suitable for walls and decorative furniture.
- Water-based 2K PU lacquers or high-quality acrylic systems.
