CQS8
CQS8 Patina, blue (solvent-borne)
Solvent-borne blue patina. Sprayed over PU or acrylic primers/enamels; after a short flash the excess is wiped back by hand with a Scotch-Brite pad or steel wool so the colour stays in the pores, profile recesses and on edges, giving an aged / decapé look. Fast-drying, easy to wipe back, very low consumption. Must be top-coated with a clear lacquer.
- Ageing (patinating) indoor furniture and wooden items
- Decapé effect on open-pore oak (colour left in the pores)
- Patina over enamel on profiled cabinet doors
- Finishing PU foam / polyurethane and polystone mouldings
- Special effects: 'stone' (CQS/CTU + S10 dripped); 'wash-out' and 'shabby chic' are specified for CQS 21–26 in the catalog — CQS8 by analogy

Standard reduction for spraying (official page and dealer).
S2000 is the dedicated patina thinner; S10 (listed by the dealer as the polyester thinner) makes the patina harder to wipe back.
- % by weight: 100–300 %catalog
Wider range per the 2025–2026 catalog — for a more transparent, lighter patina.

When the patina must wipe back more easily (subtle patina, large hand-wiped areas).
Dealer: reduced with ethyl alcohol the patina wipes off more easily, with S10 it is harder to remove. No ratio given — start at the same 100–200 %.
- S10Thinner
'Wash-out' effect (special-effects catalog p.20): neat S10 is sprayed at low pressure over fresh patina so it runs and blurs. The catalog specifies CQS 21–26; CQS8 by analogy.
Also the 'stone' effect: CQS/CTU and S10 are spattered as drops at minimum pressure. No ratios given.

Officially 'spray + rub': after spraying the patina is rubbed / wiped back by hand with Scotch-Brite or steel wool.
Process and compatibility
- Substrate preparation
- Apply over cured and sanded PU or acrylic primer/enamel (schedules: APS20/APL20 or ATS20 on oak after P240–P320 + K120 / K60–K80 pads; PPS20040 + PPL20 on PU foam after K120 pads).schedule
- Sanding
- Excess is removed by wiping, not sanding: Scotch-Brite 07448 / S UFN (oak), No.2 steel wool (PU foam). For shabby chic, selective sand-through with coarse abrasive after the patina. The special-effects catalog (p.12) words it differently: 'after drying it is sanded back, leaving the colour in pores, recesses and on edges'.schedule
- Temperature and humidity
- 20–25 °C for application and flash (schedules).schedule
- Don'ts
- Don't leave the patina without a clear lacquer — it is not a topcoat.
- Don't apply over uncured or unsanded primer/enamel — it grabs everywhere and won't wipe back.
- Don't wait too long before wiping back: past ~10 min it gets harder, especially when reduced with S10.
- Don't flood it — 80–100 g/m² is already the reduced wet amount.
