CQS44001 Patina, Copper (metallic)

Solvent-borne metallic copper patina for antique, decapé and grain-highlight effects. Leaves a copper shimmer in pores, recesses and on edges. Sprayed as one light coat over PU or acrylic primer or enamel; after 5–10 min the excess is cut back with Scotch-Brite or steel wool. Fast drying, easy to wipe back by hand, very low consumption. Must be locked in with a clear lacquer.

Stir before reducing and keep stirring while you work — metallic pigment settles. One light even coat, don't let it pool in recesses, 15–20 cm off the work. After 5–10 min cut back with Scotch-Brite (dealer: K600; decapé schedule: 07448 S UFN) or #2 steel wool (PU-foam schedule), leaving copper in pores, on edges and in the carving.

Not listed by Technocolor; production option — use a coarse (100–150 µm) filter so the metallic flake isn't stripped out.

Wipe-back

Catalog pictograms are '[Spray] + [Rub]': the patina is sprayed (80–100 g/m²) and then rubbed/cut back by hand with Scotch-Brite or steel wool. Rag application as a standalone method is not listed by Technocolor.

Process and compatibility

Substrate preparation: Dealer instruction: sand P80–120 → APS20 primer 120 g/m², dry 4 h at 20 °C → sand P280–320 → APL20 SM enamel 120 g/m², dry 3 h → patina.dealer
Goes over: APS20 / APL20 SM / APL20 / PPL20 / APL800XX / APL80093 / APL80094 / APL80048 / HTL10001 / ATL20 SM
Goes under: ATL20 SM / ATL20 / PTL500
Sanding: After 5–10 min dry, cut back: dealer — Scotch-Brite K600; oak decapé / open-pore (acrylic) schedules — Scotch-Brite 07448 S UFN; PU-foam schedule — #2 steel wool.dealer
Special effects: Metallic enamel (p.17): PPS50 → APL800XX → ATL20 SM → CQS → ATL20 SM. Desert Rose (p.19): PPS20 → PPL20 → HTL10001 → CQS 4XXXX → ATL20 SM.catalog
Temperature and humidity: 20–25 °Cschedule
Don'ts: Never leave it without a clear topcoat — lacquer is what fixes it
Don't lay it on heavy: one light 80–100 g/m² coat
Don't wait too long to cut back — after ~10 min it gets harder to remove
Not for exterior work — interior only
