Unlike the CPH concentrates (400–600 % water), CPH23/1 is officially thinned only 0–100 %. More water = lighter tone. Use clean, ideally filtered water. Always do a test panel.

Application

Consumption: 80–100 g/m²official
Recoat: 4 h at 20 °C before primer/sealerdealer
Sanding between coats: Do not sand the stain itself — the pigment cuts through to bare wood instantly. Knock down raised grain only after the first sealer coat (P280–P320).recommended

Full fan, 50 % overlap, keep moving — stopping makes dark blotches. Stir before and during use; the pigment settles.
