Which eco-friendly paints are worth using?

It’s Not Just About Color

Modern interiors are no longer just about aesthetics—they're also about health and the environment. With a rising number of allergies, concerns over indoor air quality, and growing eco-awareness, choosing a paint is no longer only a matter of color. More and more clients ask, “Is this paint safe?”—and a professional contractor should know the answer.

What Are Eco-Friendly Paints?

Eco-friendly paint minimizes its impact on human health and the environment. Key features include:

• No VOCs (Volatile Organic Compounds) – or only trace amounts, compliant with strict regulations. VOCs are responsible for the characteristic "paint smell" and can cause headaches, irritation, and poor indoor air quality.

• Natural-based composition – lime, clay, chalk, plant oils, cellulose, and other renewable, non-synthetically processed ingredients.

• International environmental certifications, such as:

  • EU Ecolabel (European Union)

  • Nordic Swan (Nordic countries)

  • Blauer Engel (Germany)

  • French Emission Class A+ – especially relevant for children’s spaces, schools, hotels, and healthcare facilities.
    

Types of Eco-Friendly Paints and Their Uses

1. Mineral Paints (lime- and silicate-based)

Among the oldest known paints—now making a comeback in improved formulations. Key properties:

• Alkaline pH – inhibits mold and mildew growth

• Very high breathability – lets walls “breathe”

• No synthetic binders – based on lime or water glass (for silicates)
  

Applications: damp spaces, historic buildings, mineral plasters, heritage renovations.
Note: Require proper substrates—not suitable for gypsum surfaces or previously painted latex walls.

2. Clay and Chalk Paints

Increasingly chosen for styled interiors—rustic, boho, loft, or vintage.

• Natural composition – clay, chalk, potato starch, oils, mineral pigments

• Soft matte finish and color depth – create a cozy, diffused light effect

• Excellent breathability – supports a natural indoor microclimate
  

Applications: bedrooms, living rooms, nurseries, libraries, private interiors.
Limitations: lower resistance to scrubbing and washing—not recommended for wet zones or kitchens unless protected.

3. Low-VOC Latex Paints with Certifications

A balance between modern performance and environmental responsibility.

• Very low VOC content (under 30 g/l or even <1 g/l) – no irritating odor

• Free from ammonia, phthalates, formaldehyde, and solvents – ideal for allergy sufferers

• Highly washable and durable – suited for high-traffic areas
  

Applications: kitchens, bathrooms, hotels, offices, homes—anywhere durability and hygiene matter.
Examples: Caparol Indeko-plus, Flugger Dekso 5, Tikkurila Optiva Nature, Benjamin Moore Natura.

When Should You Use Eco-Friendly Paints?

Eco-friendly paints are gaining importance in the context of:

• Projects for children and seniors, or people with respiratory conditions

• Passive and energy-efficient buildings – where air circulation is limited, and emissions from finishing materials matter more

• Commercial and educational spaces where health certifications are required (e.g. BREEAM, LEED)

• Eco-conscious projects – where the investor deliberately chooses low-emission, biodegradable products
  

Why Recommend Eco-Friendly Paints?

1. Health of Occupants and Users

Eco-friendly paints do not emit harmful volatile compounds such as formaldehyde, phthalates, or ammonia.
This means:

• You can safely paint rooms even when occupants (including children or seniors) are present

• No need for prolonged ventilation – rooms are ready to use quickly

• Paints are odorless or have a very mild, non-irritating smell

• They're also safe for pets, who may be more sensitive to chemical exposure
  

2. Project Prestige and Compliance with Standards

In many investments—especially public or commercial—eco paints are becoming a requirement:

• Schools, nurseries, hospitals, and clinics demand A+ emission class or valid hygiene certification

• Investors expect documentation confirming no harmful emissions—impacting inspection results and building certifications

• Environmentally friendly materials align better with sustainable construction trends and earn extra points in LEED, WELL, or BREEAM systems
  

3. Contractor Image and Competitive Advantage

More and more clients expect not just quality work, but informed advice.

By recommending eco paints, you:

• Build trust and a professional image—not just focusing on the result, but also the users’ well-being

• Stand out from competitors offering only “standard hardware store paint”

• Win loyalty from clients who value solutions in line with their values—like slow living, ecology, or low-tox lifestyles
  

What to Look for When Choosing Eco Paint?

Not every paint labeled “eco” lives up to the claim.

Check:

✅ Certifications and Environmental Declarations

• Does the paint have an international mark (e.g. EU Ecolabel, Blauer Engel, Nordic Swan) or a Polish hygiene certificate?

• Does the manufacturer provide a technical sheet and a VOC (volatile organic compound) emission declaration?
  

✅ Ingredients and VOC Level

• Choose products with VOC below 30 g/l—ideally <1 g/l (ultra-low emission)

• Avoid paints with ammonia, formaldehyde, or isothiazolinone preservatives (MIT/CMIT), which may cause allergies
  

✅ Compatibility with Substrates

• Mineral paints (lime, silicate) are not suitable for previously painted acrylic or latex surfaces

• Clay paints need dry, clean substrates—preferably mineral plasters or resin-free fillers
  

✅ Application Conditions and Technique

• Check if the paint requires specific ambient temperature (e.g. min. 10°C) or humidity

• Some eco products don’t tolerate standard synthetic primers—use mineral or dedicated undercoats

• Verify if the manufacturer recommends a specific painting technique (e.g. crisscross rolling, two coats without sanding between)
  

Summary

Eco-friendly paints are not just a trend—they’re a response to real health and environmental needs.
As their popularity grows, more clients will expect you to know how to use and recommend them.
Stay informed, test new products, and educate your investors.

Because conscious painting creates better interiors—for people and for the planet.

❓Frequently Asked Questions

Are eco-friendly paints less durable than traditional ones?
Not at all. High-quality eco-friendly paints—especially low-VOC latex variants—offer comparable durability to traditional paints. When it comes to mineral or clay paints, it's crucial to match the product to the correct type of substrate.

What’s the difference between mineral and acrylic paints?
Mineral paints (such as lime or silicate) are highly breathable and have natural antifungal properties. Acrylic paints form a flexible film, making them better suited for surfaces prone to small cracks or movement.

Are eco-friendly paints truly odorless?
Yes. Most eco-friendly paints are free from solvents and ammonia, meaning they emit little to no odor. This makes them suitable for use in rooms occupied by children, the elderly, or allergy sufferers.

How can I tell if a paint is genuinely eco-friendly?
Look for third-party certifications like EU Ecolabel, Blauer Engel, Nordic Swan, or Class A+. Check that the VOC (Volatile Organic Compounds) level is listed—preferably below 1 g/l—and make sure the manufacturer discloses the full ingredient list.

Can eco-friendly paints be applied over previously painted walls?
Yes, but it depends on the type of eco paint. Low-VOC latex paints are generally suitable for repainting. Mineral paints, however, require properly prepared surfaces—old paint may need to be removed, and the wall might require priming with compatible products.

Are clay-based paints washable?
No. Clay and chalk paints create matte, soft-textured finishes that are not water- or scrub-resistant. They’re ideal for dry, low-traffic areas like bedrooms or living rooms, but not recommended for kitchens or bathrooms.

How much do eco-friendly paints cost?
They tend to be slightly more expensive than standard retail paints, but the price gap is narrowing. Certified eco paints typically start from around 80 to 120 PLN per 5 liters, depending on the brand and formulation.
