High-end decorative paints: patinas, frescoes, signature effects

The framework

Three measurable criteria frame an office decorative paint, and only one truly makes the difference in operation:

• VOC content below 1 g/L, A+ emissions classification in accordance with the decree of 19 April 2011 on the labelling of construction products (JORF no. 0111, art. 1);
• film thickness between 200 and 600 microns depending on the technique;
• scrub resistance of level 1 or 2 according to standard NF EN 13300.

The VOCs emitted by wall paints weigh directly on indoor air quality, measured via standardised protocols for sampling and analysis in indoor environments. The environmental and usage-quality benchmarks for office buildings reward bio-sourced or mineral formulations, which significantly reduce VOC emissions.

In practical terms at Kytom: the profession over-values the scrub level in office specifications. On a signature wall in a management lobby, manual contact remains very limited. Requiring a scrubbable level 1 wrongly disqualifies deep matt finishes and mineral patinas, which are precisely the heart of the decorative range. Level 2 or 3 is sufficient in low-contact areas and frees up the colour trade-off.

Your gains

Three quantified benefits for CFO, HR Director and Asset Manager

We reframe decorative paint from the angle of budget arbiters, not from the aesthetic angle. Our feedback from projects of 850 sq m on average confirms three effects regularly observed by our HR Director and Asset Manager contacts: an improved perception of the work environment by employees, a positive contribution to retention, and an appreciation of the property asset, effects consistent with the conclusions of reference observatories on quality of life at the office.

• HR attractiveness (HR-QWL reading): employees positively perceive the improvement of their work environment after delivery, and our HR partners regularly observe a stabilisation of turnover in the months following move-in. For a 300-employee head office, each point of turnover avoided represents several fewer hires.
• Property appreciation (Asset Manager reading): quality works help support rental value and the capitalised valuation of the asset. The premium materialises on the headline rent and therefore in the capitalised valuation at a constant rate, not necessarily in the economic rent after incentive measures.
• Durability and OPEX (CFO reading): a properly executed lime patina lasts 15 to 20 years without a full repaint, versus 7 to 10 years for a standard acrylic, i.e., over a 20-year cycle, a significantly reduced maintenance cost. The initial extra cost tips into OPEX savings from the 8th financial year.

Honesty

When decorative paint is NOT the right answer

Three configurations disqualify the approach, and we tell you this before the costing rather than after.

Below 80 sq m treated on a floor, the fixed cost of mobilising a decorative painter (travel flat fee, sampling, colour validation) crushes the EUR excl. VAT/sq m ratio. A standard matt quality A finish remains more rational, and we steer towards a colour specification alone, without heavy craft mobilisation.

Beyond 1,500 people/day in footfall (station concourses, high-rotation receptions, public spaces), a non-scrubbable deep matt finish degrades in less than 24 months. You then need to switch to a technical vinyl wall covering or a sealed polished concrete, with a tighter maintenance specification.

In a rental project with a holding horizon of less than 5 years, the extra cost of 45 to 80 EUR excl. VAT/sq m versus a standard matt paint is recovered neither in appreciation nor in lifespan. We then recommend concentrating the image expense on signage and furniture, which are more easily reversible on exit.

Method

1. Substrate diagnosis
   We start with a moisture survey targeting a level below 4%, compliant with DTU 59.1 and FIPEC recommendations. A cohesion test and the identification of substrates (plaster, concrete, plasterboard) frame the technical constraints before any colour costing.
2. Colour specification
   We select from the 132 Farrow & Ball shades (2024 colour chart), the 240 Argile references or the 180 Ressource shades. Each chosen shade is validated using 50 x 50 cm samples placed on site, under the final lighting, to neutralise rendering discrepancies.
3. Technical choice
   Lime patina for reception lobbies, contemporary fresco for management rooms, copper or brass metallic effect for premium areas, mineral polished concrete for circulations. The specification rule is based on our 2018-2024 feedback.
4. Execution
   Mobilisation of craftspeople or 6113, with 3 to 5 coats depending on the desired effect and a drying time between coats of 12 to 24 hours (supplier specifications). The intervention integrates into the overall works schedule, within the average lead time of 12 weeks.
5. Handover
   Joint appearance report, clearing of any reservations and handing over of a detailed maintenance sheet to your operator. After-sales support open for 24 months, integrated into our portfolio arrangement.
