CQS19872 Patina, red walnut

Solvent-borne patina in a red-walnut shade. Sprayed over polyurethane or acrylic primers (and enamels), then the excess is rubbed back with steel wool or a Scotch-Brite pad, leaving colour in the pores, recesses and on profile edges. Dries fast, wipes back easily by hand, very low consumption; used to give indoor furniture and joinery an aged look.

Antique/aged effect on indoor furniture and joinery
Decapé finish over enamel on oak kitchen doors
Open-pore oak: colouring the pores over clear acrylic primer
Ageing polyurethane-foam (PU/PPU) mouldings and decor
Special effects: wash-out ('razmytie'), shabby chic, faux stone (dripped)

Application

HVLP

Consumption: 80–100 g/m2official
Nozzle: 1.2–1.4 mm (1.3 typical)recommended
Pressure · air: inlet 1.5–2.0 bar with trigger pulled (cap ≈0.5–0.7 bar)recommended
Pressure · fluid: gravity cup, fluid knob 1–1.5 turnsrecommended
Spray viscosity: as diluted (very thin, ~11–14 s DIN4); adjust strength with dilution, not by thickeningrecommended
Wet film: ≈90–120 µm wetrecommended
Coats: 1 even coat; spot-mist only to deepen tonerecommended
Flash-off: 5–10 minschedule
Recoat: topcoat 10–15 min after wipe-backrecommended
Sanding between coats: Excess is removed by abrading back with Scotch-Brite 07448 S UFN (acrylic schedules) or steel wool No 2 (PU-foam schedule) after 5–10 min; the special-effects catalog describes this as 'sanding back after drying, leaving the patina in pores, recesses and on edges'. No separate sanding step between patina and lacquer in the schedules.schedule
Gun distance: 15–20 cmrecommended

Stir well before thinning and agitate the cup now and then – pigment settles. Check colour on a sample board with the same primer/enamel system.

Conventional spray

Consumption: 80–100 g/m2official
Nozzle: 1.2–1.4 mmrecommended
Pressure · air: 2.0–3.0 bar at gunrecommended

For the 'wash-out' effect, spray neat S10 over the patina with a low-pressure gun.

Airmix (air-assisted airless)

Consumption: 80–100 g/m2official
Nozzle: tip 07–09 thou (0.18–0.23 mm), narrow fanrecommended
Pressure · fluid: 6–12 barrecommended
Pressure · air: 1–1.5 barrecommended

Cloth or pad

The 2025–26 catalog shows 'spray' and 'rub-in' icons: patina can be rubbed in with a rag or stippling brush, useful on small parts and restoration.

Process and compatibility

Substrate preparation: Apply over cured, sanded acrylic or PU primer/enamel: decapé – APL20 enamel dried 1.5 h at 30–35 °C; open-pore oak – ATS20 primer dried 1.5 h at 30–35 °C and sanded P240–P320 / K60–K80; PU foam – PPL20 enamel dried 4 h at 20–25 °Cschedule
Goes over: ATS20 / APL20 / PPL20 / APL (RAL/NCS) enamel / PU (RAL/NCS) enamel / ATL20 SM
Goes under: ATL20 / ATL20 SM / ATL20 UM / ATL500 / ATL200 / PTL500
Sanding: Patina is not sanded as a separate operation; the excess is abraded back with Scotch-Brite 07448 S UFN or steel wool No 2 (schedules). For shabby chic, selective sand-through with coarse abrasive after the patina, before lacquer (special-effects catalog).schedule
Temperature and humidity: 18–25 °C, RH 50–70 %recommended
Don'ts: Don't leave it too long before wiping back – thinned with S10 it grabs and wipes unevenly
Don't apply over uncured or unsanded primer/enamel – the solvent can lift it
Don't leave patina uncoated – it is not a finish
Don't overload (>100 g/m²)

Storage

Storage temperature: +5…+25 °C, tightly closed, away from heat/ignitionrecommended
Packaging: 1 l and 5 l (dealer pack sizes); dealer price 990 ₽/l (2026-10-04)dealer

Safety: Contains organic solvents, highly flammable. Spray in a booth with extraction, wear an organic-vapour respirator (A2) and gloves; no smoking or sparks. Keep patina-soaked rags in a closed metal bin.
