CPH25
CPH25 waterborne pigment stain, mahogany
Waterborne pigment stain in mahogany. Evens out colour variation and hides wood defects, levels the tone well, good lightfastness. Supplied as a concentrate reduced with water; CFH1 binder is already partly included.
- colouring furniture in any wood species
- evening out mismatched timber (beech, birch, finger-jointed panels, veneer)
- tinting exterior coatings (per catalog)

Mixing matrix
- waterThinner% by weight: 400–600 %official% by volume: 400–600 %official
Standard reduction per the manufacturer's site: 4–6 parts water to 1 part stain.
More water = lighter, more transparent tone. Use clean soft (filtered/distilled) water at room temperature.
- waterThinner% by weight: 400–1000 %catalog
The 2025–2026 catalog states 'Water 400–1000 %' for the series without explanation. The high end (our interpretation) suits pale, see-through tones and roller application.
The catalog gives one range for the whole CPH series: 'Water 400–1000 %'.
- CFH1Additive% by weight: 0–200 %official% by volume: 0–200 %official
CFH1 binder is added for more even laydown and less grain raising, especially at high water reductions.
Per the dealer the stain already contains ~15–20 % CFH1, so extra binder is optional (hence the 0 % lower limit).
- CFH1Additive% by weight: 0–400 %catalog
The 2022 catalog allowed up to 400 % CFH1 (matches the CFH1 400 % ratio in the official schedule for CTH dyes).
Older catalog; the current product page says 0–200 %. Work to 0–200 %.
- CFH1Additive% by weight: 15–20 %dealer
Already added at the factory.
'For more even application and reduced grain raising, CFH1 binder (15–20 %) has been added to the stain.'
- % by weight: 0–100 %dealer
Colour matching: all CPH stains intermix in any ratio (bases CPH1 yellow, CPH3 red, CPH9 black, CPH10 white).
Blend the concentrates before adding water; always do a test panel on the same species.

- Don't sand the stain itself — it cuts through to bare wood easily. Knock the raised grain down after the first primer coat (P280–P320).recommended
Lay one even wet coat, 50 % overlap, gun 15–20 cm off; don't flood verticals — stain runs leave dark streaks.

Spray then wipe (2025–2026 catalog): spray on and immediately rub in with a sponge/rag or brushes to even the tone and bring out the grain.
Roller
- Consumption

Roller-coater for flat panels/flooring, 10–20 g/m² (2025–2026 catalog). The catalog gives 400–1000 % water for the series; tying the high end to roller use is our reading, not stated.
Airless
- Nozzle
- not recommendedrecommended
Not recommended for stain: delivers far too much material, uneven colour.
Process and compatibility
