CFH1

CFH1 Water-based stain binder for spraying

Water-reducible binder for spray-applied stains. It is added together with water to stain concentrates (CPH, CTH, and CLT/CTU when they are cut with water) to even out the colour, lock the dye onto the wood and reduce bleeding of the stain into the following primer. Solvent-borne counterpart: CFS1; dipping counterpart: CFH2.

  • Binder for CTH water stains applied by spray (CTH 100 : CFH1 400 : water 1000)
  • 0–200 % addition to CPH water-based pigment stains
  • 0–200 % addition to CLT and CTU stains when they are reduced with water (use CFS1 with solvent)
  • Open-pore veneer / solid wood finishing under PTS60 PU primer and PTL61 PU lacquer

Mixing matrix

  • waterThinner

    Working spray mix for CTH stain.

    Recalculated from the schedule recipe; reduce with water only. The schedule does not say whether parts are by weight or volume; with near-water densities the difference is minor.

  • CTH1 / CTH3 / CTH4 / CTH9Additive

    Open-pore oak/veneer, stain sprayed at 80–100 g/m².

    The schedule uses 4× more binder than dye — above the 0–200 % stated on the stain cards; it is a recipe for the transparent CTH dyes. The schedule does not say whether parts are by weight or volume; with near-water densities the difference is minor.

    Only when CLT/CTU are reduced with water. With S10/S12/S90 use CFS1 instead.

    Cards list 'CFS1/CFH1'; picking by thinner type is an engineering inference.

Don'ts
  • Don't add to stains reduced with S10/S12/S90 solvents — use CFS1 there
  • Don't sand the stain coat before priming — you'll cut through the colour
  • Don't exceed ~100 g/m²: raised grain and blotching
  • Don't reduce with tap water — deionised only (dealer note for water-reduced stains)

Storage

Safety: Water-borne material. Wear gloves and a respirator when spraying, ventilate. (No SDS found.)
