Interior Painting

Mineral and plant-based paints applied with technical precision. No lingering smells, no toxins, certified at the end.

Kitchens & Bathrooms

Mineral finishes for humid spaces. Breathable, moisture-resistant, and built to last daily life.

Work Spaces

A healthier environment where work flows better. Non-emitting paints, focus-supporting colours, finishes that last.

Furniture & Details

The difference is in the details. Doors, mouldings, fixtures and singular elements treated with the same care as the walls.

300+possible toxins in conventional paints

Why should you care?

Acrylic paint is essentially plastic on your walls. These chemicals (formaldehyde, benzene, toluene) are continuously released into your home's indoor air for weeks or months.

Common symptoms:Headaches, asthma, eye irritation and itchy throat in enclosed spaces.

Especially at risk:Babies, pregnant women and people with MCS.

The Gelur difference: VOC-free — for real

Brands talk about "low emissions" (greenwashing) but allow toxic margins. We only use mineral chemistry where VOCs simply do not exist.

✓

No petrochemical derivatives

Living materials based on lime, silicates, clay, and plant oils and resins.

✓

Breathable and anti-mold home

Without plastic, the wall regulates moisture naturally, preventing condensation and mold proliferation.

✓

Ingredient-by-Ingredient Certification

VOC-free isn't a marketing slogan. When we finish, we hand you the 'Certified Natural Paint' seal — a document with the technical data sheets for every product used, ingredient by ingredient.

Your apartment should be the place where you breathe the easiest.

From Idea to Wall

Real projects where eco-friendly paint transforms both health and aesthetics.

Calç Natural

01

Living Room Intervention

Situation

Old house under renovation. The main space—living room, dining room, and kitchen—is painted entirely in white. The visual reading is homogeneous and flat.

Opportunity

Darkening this wall breaks the white uniformity and builds a richer spatial reading. The dark green establishes a natural continuity with the village exterior.

Material & Technique

Lime paint: a mineral material that breathes, regulates humidity, and offers a matte finish with a slight vibration that scatters light, creating nuances.

Argila Natural

02

Transformation of a Degraded Hallway

Situation

Access hallway to the staircase in a degraded state: cracks, irregular areas, and worn surfaces. The space felt tired and lacked cohesion.

Opportunity

Clay mortar is applied to level the support without losing its character. A soft ochre activates the space, adding warmth to the transition to the stairs.

Material & Technique

Clay paint: a material that regulates humidity and reduces ambient dryness. The finish is completely matte, absorbing light and providing vibration.

03

Wooden Window Restoration

Situation

Eixample apartment with wooden windows showing signs of time and weather exposure: dried-out areas and aged paint layers.

Opportunity

The original white is kept to respect the heritage and shared landscape of the Eixample courtyard, accompanying the light without imposing.

Material & Technique

Water-based enamel for wood: moisture and temperature-resistant, allowing breathability, with a soft satin finish for easy maintenance.

Interior Woodwork Update

Situation

Built-in wardrobe doors in an old apartment. The original dark brown felt visually heavy and darkened the space.

Opportunity

Painting the doors in a rosy gray lightens their presence and integrates them into the room, updating the look without losing history.

Material & Technique

Water-based enamel: scuff-resistant and easy to clean. Creates a uniform layer that regularizes the surface with great chromatic sensitivity.
