At Pinturas DECOLOR, we know that the secret behind a perfect and long-lasting finish lies not only in the quality of the paint, but also in the preparation of the substrate before painting and that it is suitable for each surface.

Although it is often underestimated, surface preparation is a crucial step that can make the difference between a professional finish that lasts over time and a job that deteriorates quickly. Therefore, it is necessary that the surface on which we work, be it a wall, a ceiling, a terrace, a facade, a metal surface or any other type, is perfectly healthy and clean.

If proper preparation is not carried out, any material we apply, regardless of its quality, will not adhere properly and will eventually peel off over time. In addition, in cases where microorganisms or saltpeter are present, it is important to consider that their presence may be related to humidity problems. These problems not only affect the finish, but if not corrected, they will reappear, damaging both the support and the paint.

Benefits of properly preparing the substrate before painting

The correct one preparation of the support Not only is it an essential step, but it provides multiple benefits that optimize both the painting process and the quality of the final finish. By devoting time and effort to this preliminary step, you will not only guarantee a more aesthetic and quality finish, but also greater durability and resistance of the project to adverse conditions.

🔸  Better paint adhesion and performance

Paint, no matter how technologically advanced it is, needs a suitable base to achieve its maximum performance. If the surface is not properly prepared, the paint will not be able to adhere evenly, which can cause problems such as peeling, flaking, bubbling or staining. A clean, dry and blemish-free surface allows the paint to adhere optimally, achieving a more uniform finish with better coverage.

🔸 Helps bind calcareous surfaces

For chalky or porous surfaces, the use of a surface conditioner is essential, as it helps to create a solid and stable base on which the paint can adhere efficiently. This prevents the paint from degrading quickly on these types of surfaces, ensuring greater durability.

🔸 Improves adhesion in masonry paint
When preparing masonry surfaces, applying suitable products helps improve paint adhesion, ensuring that the paint remains firmly attached to the substrate, even under adverse conditions such as exposure to outdoor weather.

🔸 Surface sealing

Sealing the surface helps to even out the porosity of the substrate, preventing paint from being absorbed unevenly and causing cracks or imperfections in the finish. Sealing also acts as a barrier against alkali and efflorescence, which are common on substrates such as concrete or brick. This prevents salt and mineral deposits from damaging the finish and ensures that the result is more durable and uniform.

🔸 Preventing future damage and premature wear

By properly preparing the surface, you eliminate factors that can affect the durability of the finish. Dirty, damp, mouldy, efflorescent or cracked surfaces are prone to deteriorate quickly, regardless of the quality of the paint used. By ensuring that the surface is completely sealed and free of defects, you prevent external factors, such as moisture or dirt, from seeping through the paint, preserving its integrity for longer.

🔸 More uniform and professional finish

Removing imperfections and smoothing the surface allows for a smoother final finish, without visible stains or irregularities.

🔸  Optimizing paint usage

When a surface is well prepared, paint is distributed more evenly and efficiently, reducing the number of coats required and therefore less paint is needed to achieve optimal coverage. This means that not only is the aesthetics of the finish improved, but product waste is also reduced. A poorly prepared wall will absorb more paint in some places and reject in others, requiring more coats or touch-ups, which increases the overall cost and application time of the job.

🔸 Greater durability of the finish

A well-prepared substrate helps make the paint more resistant to external aggressions, such as weather, humidity or wear. This significantly prolongs the life of the finish, reducing the need for frequent touch-ups or repainting.

🔸  A more aesthetic and professional finish

As manufacturers, we understand that the final appearance is critical to our customers. Good surface preparation not only ensures the durability of the work, but also improves its final appearance. Uneven surfaces, holes, cracks, stains and traces of untreated contaminants will show through even the best paints. By preparing the surface well, a smoother and brighter finish is achieved, which highlights the properties, colour and texture of the paint.

🔸  Avoid long-term problems

Failure to properly prepare the surface before painting can lead to problems that become apparent over time. Paint may begin to peel, moisture stains may appear, or mold may develop in certain areas. On the other hand, a well-treated and sealed surface ensures that the paint will act as a protective barrier, prolonging the life of the finish and ensuring that the customer will be satisfied for many years to come.

Although it may seem like an additional task, as we have seen, the benefits far outweigh the effort invested in preparing the substrate before painting, ensuring that the finish of the paint job is not only optimal, but also withstands the passage of time and environmental conditions.

To ensure that all these benefits are obtained, at Pinturas DECOLOR, we offer a wide range of solutions, which help to optimally prepare according to the type of surface and the needs of the project, including Primer water based, ideal for interiors or sensitive surfaces, solvent funds, perfect for outdoors and surfaces exposed to more demanding conditions, such as metals or facades exposed to extreme conditions, and high quality putties, for repairing cracks and fissures, ensuring a completely uniform surface before applying the final paint.

Difference between water-based primers, solvent-based primers and putties in substrate preparation

The choice between Primer water based, solvent funds or the use of putties is essential in the preparation of the substrate, since each product offers specific characteristics and benefits depending on the type of surface and the conditions to which the final finish will be exposed. Below, we explain their differences.

 🔸  WATER-BASED BACKGROUNDS (preparation of the support)

They are perfect for applying surfaces interiors or in environments with little exposure to extreme weather conditions. They work very well on porous surfaces such as plaster, cement and masonry, where a quick seal is required without releasing harmful substances.

They are used in interior projects, where a quick application is sought, without strong odors, and on surfaces that require controlled porosity.

There are many benefits of water-based funds, among which we highlight the following:

• Quick drying, which speeds up the painting process.
• Easy to clean, as they only require water.
• Low toxicity and minimal odors, making them perfect for interior projects or inhabited areas.
• Good adhesion on plaster, plasterboard and porous materials.

At Pinturas DECOLOR we offer a wide range of water-based primer products that adapt to the different needs of professionals.

🔸  SOLVENT-BASED BACKGROUNDS (support preparation)

They are applied in exteriors or surfaces requiring greater protection, such as metals, wood, facades exposed to the elements or substrates with greater porosity and alkalinity. They are also useful when blocking alkali and efflorescence on substrates is required.

They are used on exterior surfaces, areas exposed to moisture, metal surfaces, masonry with high alkalinity, or projects that require a more robust and durable barrier.

There are many benefits of solvent-based funds, among which we highlight the following:

• Greater resistance to weather, moisture and wear.
• Excellent adhesion on difficult surfaces such as metals and wood.
• Greater sealing capacity to prevent problems such as efflorescence and cracking on porous surfaces.
• They provide a stronger, more durable finish in extreme conditions.

At Pinturas DECOLOR we offer different solvent-based base coat solutions that adapt to the different needs of professionals.

🔸  PUTTIES (preparation of the substrate)

Putties are essential in any type of painting project, as they allow you to fill defects in plaster, cement, wood or metal surfaces. They are applied before the primer and are key to ensuring that the surface is completely smooth.

Putties are used to repair surfaces in any type of project, both indoors and outdoors, where it is necessary to cover cracks in walls, seal joints in wooden surfaces, and fill imperfections in masonry and metal.

Among the benefits provided by putties we highlight the following:

• Effective repair of cracks and holes, leaving the surface ready for painting.
• Available for different types of surfaces, whether indoor or outdoor.
• They improve the uniformity of the support, reducing the appearance of imperfections in the final finish.
