CLT12

Kromolux brown wood dye (concentrate)

Concentrated transparent wood dye (stain) without binder, Kromolux series. Very even colour and high clarity; at higher strength gives deep dark tones while staying see-through. Reduce with water or solvent, with or without binder. Can be overcoated with polyester, polyurethane and nitrocellulose lacquers.

  • Staining any timber, veneer or solid
  • Furniture, mouldings, frames, general joinery — spray
  • Mixing/matching shades with the other CLT dyes
  • Deep dark tones that stay transparent

Mixing matrix

  • S10Thinner
    % by weight: 500–1000 %dealer% by volume: 500–1000 %dealer

    Fast, strong thinner — for close-grained timber (beech, birch, maple, alder), small parts, cool shop.

    The Technocolor catalog gives the same 500–1000 % and the same S10/S12/S90 set for its universal dyes.

  • S12Thinner
    % by weight: 500–1000 %dealer% by volume: 500–1000 %dealer

    Medium evaporation — for medium-pore timber; the all-round choice for hand spraying. Technocolor's stain schedules use S12.

    The Technocolor catalog gives the same 500–1000 % and the same S10/S12/S90 set for its universal dyes.

  • S90Thinner
    % by weight: 500–1000 %dealer% by volume: 500–1000 %dealer

    Slow — for open-pore timber (oak, ash, anegre), big panels, hot weather; gives the stain time to soak into the pores, fewer stripes and lap marks.

    The Technocolor catalog gives the same 500–1000 % and the same S10/S12/S90 set for its universal dyes.

  • WATERThinner
    % by weight: 500–1000 %dealer% by volume: 500–1000 %dealer

    Water-borne stain: raises the grain more and pops the figure, but dries slowly (about 8 h at 20 °C per TDS).

    Deionised water only — tap water makes the dye flocculate and hurts colour stability (dealer note).

  • LZC97Thinner
    % by weight: 500–1000 %official% by volume: 500–1000 %official

    Milesi slow thinner (per the Milesi LZC sheet — for roller stains, CIT series). In the TDS recipe it is a small fraction mixed with the main thinner, slowing drying and evening the colour.

    Dealer does not list LZC97 for CLT12; it appears on the series' official page (CLT1) and in the TDS.

  • LZC97 / LZC1000Thinner

    Manufacturer's (Milesi) suggested solvent dilution.

    LZC1000 is Milesi's fast acetone thinner (LZC sheet: spray stains, polyesters, gun cleaning); not in the Technocolor range — nearest by purpose is S10 (fast, for stains).

  • LZC97 / WATERThinner

    Manufacturer's suggested water dilution.

    Deionised water.

  • CFS1Additive
    % by weight: 0–200 %dealer% by volume: 0–200 %dealer

    Solvent-based spray binder: less grain raising, the primer doesn't drag the dye, more even colour on end grain.

    Can be used with no binder (0 %). Official (CLT1 page): CFS1/CFH1 0–200 %.

  • CFH1Additive
    % by weight: 0–200 %dealer% by volume: 0–200 %dealer

    Water-based spray binder — when CLT12 is reduced with water.

    Don't put CFH1 into a solvent-reduced batch.

  • CFS1 / S12Additive
    % by weight: CLT12 100 : CFS1 150–200 : S12 500 parts (schedules print '%' without weight/volume basis)

    Working dye+binder mix under a PU/UV system, mirroring Technocolor's schedules for the CTU transparent dyes.

    The 'panel doors PU' (CTU 100 : CFS1 200 : S12 500) and 'mouldings/frames UV' (CTU 100 : CFS1 150 : S12 500) schedules name CTU, not CLT; CLT12 is the same class (transparent concentrate, same thinners and spread rate).

Percentages are per 100 parts of component A.

Process and compatibility

Substrate preparation
Sand veneer P150–P220, solid P150–P180 (Technocolor stain schedules); de-dust. Coarser grit = more uptake and a darker tone, finer = lighter; end grain always goes darker (CFS1 binder helps). For water-reduced stain, raise the grain with water first and knock it back at P220.schedule
Goes over
bare, sanded wood (veneer or solid)
Goes under
polyester primers/lacquers / PU primers/lacquers / acrylic (2K) primers / NC lacquers / UV primers (per Technocolor UV schedules for analogous dyes)
Sanding
Never sand the dye coat itself — you'll cut through the colour. Knock down the fibres on the first primer coat.

Don'ts
  • Don't reduce with tap water — deionised only
  • Don't put CFH1 (water binder) into a solvent-reduced batch
  • Don't prime over water-reduced stain until dry (8 h at 20 °C minimum)
  • Don't sand the stain coat
  • Don't spray the neat concentrate — blotches and stripes

Safety: Solvent-based concentrate: flammable; spray in a booth with extraction, wear an A-filter respirator and nitrile gloves. Stains skin and clothes badly. (general practice — no SDS found)
