2K acrylic (acrylic polyol + aliphatic isocyanate AC40) over solvent-borne pigment glaze, patina and dye
Open-pore finish for oak kitchen doors (acrylic)
- Substrate
- Oak (solid or veneer) — kitchen cabinet doors, including profiled ones
- Result
- Toned oak with open pores picked out by glaze and patina, under a non-yellowing clear acrylic lacquer at 10–40 GU
- 01
Sanding the flat surfaces
Abrasive: P150, P180, P220
Work through P150 → P180 → P220 along the grain. Don't go finer than P220 on oak: the pores clog with dust and take the glaze less well.
- 02
Sanding the profiles
Abrasive: K60, K80
Profiles and routed edges are done with flexible abrasive mats K60 and K80 (designation as given in the official schedule; these are mat grades, not FEPA P60/P80 paper).
- 03
Applying the glaze (wiping stain)
CGS 100 %
Officially sprayed and then rubbed in, 80–100 g/m² (CGS21 page). Long open time, so large panels are workable. Stir thoroughly — the pigment settles.
- 04
Wiping off excess stain
Brush the excess out along the grain: the glaze stays in the pores and brings out the oak figure while the surface evens out in tone.
- 05
Drying
Drying: 20 °C, 10 min
10 min at 20 °C before priming (official schedule).
- 06
Priming
- 07
Drying
Drying: 30–35 °C, 1.5 h
Forced drying, 1.5 h at 30–35 °C. At 20 °C the dealer gives 4 h before sanding (ATS20).
- 08
Sanding the primer
Abrasive: P240, P280, P320
Light de-nib with P240 → P280 → P320, just enough to knock down raised fibres; don't cut through the primer into the glaze.
- 09
Sanding the profiles
Abrasive: K60, K80
Profiles with K60/K80 mats; go easy on edges where the primer is thinnest.
- 10
Applying the patina
- 11
Drying
Drying: 20–25 °C, 5 min
5 min at 20–25 °C (dealer gives 5–10 min before wiping back for CQS10).
- 12
Wiping back the patina
Abrasive: Scotch-Brite 07448 S UFN
Rub the patina off the flats by hand with the pad so it stays only in the pores and profiles. "07448 S UFN" is the 3M Scotch-Brite non-woven pad reference, not a Technocolor product.

Applying the lacquer
- 14
Drying
Drying: 30–35 °C, 1.5 h
1.5 h at 30–35 °C (numbered "11" by mistake in the official schedule). At 20 °C: touch-dry ~20 min, fully dry 8 h (dealer); full chemical resistance takes several days.

- Min cycle time: why
- Sum of the schedule's drying steps: 10 min + 1.5 h + 5 min + 1.5 h = 3 h 15 min with forced drying at 30–35 °C; excludes sanding/wiping labour. At 20 °C expect ~1 working day (ATS20 4 h to sand, ATL20 8 h full dry).
