CLT57

CLT57 Kromolux dye concentrate, cherry

Highly concentrated transparent dye (binder-free stain) from Milesi's Kromolux series in a cherry shade (warm red-brown; check the exact tone against a dealer sample). Very clear and even; at higher strength it goes dark while staying transparent. Dilutes with water or solvent, with or without a binder.

  • Staining all kinds of timber (dealer), veneer and solid (catalog 'Dyes' intro)
  • Spray staining of furniture, profiles, frames and wooden articles in general (Milesi TDS)
  • Evening out colour variation and toning (catalog general 'Dyes' intro); can be overcoated with PE, PU and NC lacquers

Mixing matrix

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

    Fast, strong thinner — for fine-pored timber (beech, birch, maple, alder) and short flash-off between operations.

    Thinner selection per the Technocolor 2025–2026 catalog thinner table. S10 is also the gun-cleaning solvent per its official page.

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

    Medium evaporation — medium-pored timber (cherry, walnut, tight ash); the default for a solvent-borne stain.

    S12 is the dye thinner per its official page, and it is the thinner used in the dye steps of the official schedules.

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

    Slow — open-pored timber (oak, ash), large panels, hot shop: stays wet longer, fewer blotches and lap marks.

    Dealer lists S90 as 'slow dye thinner'.

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

    Water dilution — less odour/VOC, raises the grain more and dries much slower (Milesi TDS: 8 h at 20 °C vs. minutes on solvent).

    Deionised (distilled) water only — tap water makes the dye flocculate and lose colour stability (dealer note). Before a water stain, raise the grain with a damp sponge, dry and denib at P180–P220.

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

    Listed by Technocolor as a thinner. The Milesi TDS uses LZC97 as a small-share co-solvent alongside the main thinner (see the TDS rows).

    LZC97's exact function is not documented by Technocolor; no product page.

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

    Binder for the solvent-borne stain (with S10/S12/S90): locks the dye in, less bleeding/lifting when the sealer goes on, more even colour on end grain.

    Role: binder. CFS1 = solvent-borne and CFH1 = water-borne follows from the schedules (CFS1 paired with S12, CFH1 with water); the dealer row 'CFH1 / CFS1' is labelled 'ОР / ВР' (solvent/water), i.e. the reverse mapping.

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

    Binder for the water-diluted stain.

    0 % = plain dye stain; with binder the colour holds better under the sealer.

  • LZC97 / LZC1000Thinner
    % by weight: CLT 1 : LZC97 0.5 : LZC1000 9.5 (≈ LZC97 50 % + LZC1000 950 %)datasheet

    Milesi's suggested solvent dilution. LZC1000 is a Milesi code; in the Technocolor line its place is taken by S10/S12/S90 per the official page.

  • LZC97 / WATERThinner
    % by weight: CLT 1 : LZC97 1 : water 14 (≈ LZC97 100 % + water 1400 %)datasheet

    Milesi's suggested water dilution.

  • LZC1000 / LZC1024 / LZC97 / LTC5 / WATERThinner
    % by weight: 500–800 %datasheet

    Milesi TDS: manual spray 5–20 g/m², fixed automatic airmix/airless and swinging-arm guns 10–20 g/m² — 500–800 % dilution; rotating carousel 5–20 g/m² — 700–1500 %.

    TDS thinner list: LZC1000 / LZC1024 / LZC97 / LTC5 / water (Milesi codes). Carousel: 700–1500 %.

  • CFS1 / S12Additive
    % by weight: CFS1 200 % + S12 500 %schedule

    Raised-panel doors (PU): stain 80–100 g/m², 5 min at 20–25 °C, then PTS20+C25+S50 sealer.

    The finishing schedule names the generic code 'CTU' (universal transparent dye). CLT57 sits in the same 'Universal dyes' section on t-color.ru, so the recipe is carried over as a guide; that mapping is our interpretation, not an explicit CLT57 instruction.

  • CFS1 / S12Additive
    % by weight: CFS1 150 % + S12 500 %schedule

    Mouldings and frames (UV): stain 80 g/m², 5 min at 25–30 °C, then VTS40041 UV sealer.

    The finishing schedule names the generic code 'CTU' (universal transparent dye). CLT57 sits in the same 'Universal dyes' section on t-color.ru, so the recipe is carried over as a guide; that mapping is our interpretation, not an explicit CLT57 instruction.

  • CFH1 / WATERAdditive
    % by weight: CFH1 400 % + вода/water 1000 %schedule

    Open-pore oak kitchen fronts: stain 80–100 g/m², 20 min at 20–25 °C, PTS60+C26+S50 sealer.

    This schedule is written for the water dye CTH, not CLT; 400 % CFH1 exceeds CLT57's official 0–200 % — stay within 0–200 % for CLT57.

Percentages are per 100 parts of component A.

Sanding between coats
do not sand the stain coat itself; denib the first sealer coat at P240–P320recommended

Hold the gun square at 15–20 cm, 50 % overlap. On profiles do edges and recesses first, then the field. Stir the mix before filling.

Consumption
80–100 g/m² (dealer prints 'Распыление: 80-100 г/м2'; ready mix assumed)dealer

Classic air spray — the mainstream method per the methods page (up to 40 % transfer).

Airmix (air-assisted airless)

Pressure · fluid
4–8 barrecommended
Pressure · air
0.8–1.5 barrecommended
Consumption
10–20 g/m² (TDS figure — appears to be concentrate, see notes)datasheet

The Milesi TDS states 10–20 g/m² for fixed automatic airmix — given the 500–800 % dilution this probably means concentrate (≈60–180 g/m² of ready mix, overlapping the dealer's 80–100 g/m²). Our interpretation.

Airless

Nozzle
0.18–0.23 mm (07–09 thou)recommended
Pressure · fluid
30–60 barrecommended
Consumption
10–20 g/m² (TDS figure, likely concentrate)datasheet

For hand work prefer airmix/HVLP — airless has a coarser fan and more blotch risk.

Automatic rotating spray

Consumption
5–20 g/m² (automatic rotating spray guns / carousel, TDS; dilution 700–1500 %)datasheet

Milesi TDS covers automatic rotating (carousel) spray guns at 5–20 g/m² and 700–1500 % dilution. This is not electrostatic application — the TDS does not mention electrostatic use for CLT.

Don'ts
  • Don't dilute with tap water — deionised only
  • Don't exceed 200 % CFS1/CFH1 binder
  • Don't flood the surface — make a second light pass instead
  • Don't sand the bare dye coat — sand the sealer
  • Don't seal a water-diluted stain before it is fully dry (TDS: overcoat after 8 h at 20 °C; dries in 20 min in an IR tunnel at 60 °C)

Safety: Composition and hazard class are not published (no CLT57 SDS found). Treat the concentrate and S10/S12/S90 mixes as flammable: spray in an extracted booth, no ignition sources, A2P2 respirator and nitrile gloves; keep solvent rags in a closed metal bin.
