CLT56

CLT56 Kromolux dye, Apple

Highly concentrated transparent dye (binder-free stain) from Milesi's Kromolux series in Apple (named after the fruitwood, the tone itself is not described officially — check the exact shade 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, veneer and solid
  • Furniture, fronts, mouldings and frames, general wooden articles
  • Toning and evening out colour variation under 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.

    Use per the Technocolor 2025–2026 catalog thinner table (stains on fine-pored timber, PE primers, patinas). Also usable for cleaning equipment per its official page. Dealer labels it 'thinner for PE'.

  • 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 suitable for thinning dyes' per its official page, and it is the thinner used in the dye steps of the official schedules. Dealer labels it 'NC thinner'.

  • 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'; S90 has no official product page.

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

    Water dilution — less odour/VOC, raises the grain more and dries much slower (Milesi TDS: 8 h at 20 °C vs. 30 s on LZC1000 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. The dealer table also lists water ('…/ Вод[а]') among the thinners.

  • 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's ОР/ВР labels are listed in the opposite order.

  • 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, fixed automatic airmix/airless, swinging-arm guns — 500–800 %; rotating 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). CLT56 itself has no t-color.ru page; its sibling CLT4 sits in the 'Universal dyes' section, so the recipe is carried over as a guide; that mapping is our interpretation, not an explicit CLT56 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). CLT56 itself has no t-color.ru page; its sibling CLT4 sits in the 'Universal dyes' section, so the recipe is carried over as a guide; that mapping is our interpretation, not an explicit CLT56 instruction.

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

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

    This schedule (open-pore oak kitchen fronts, acrylic) is written for the water dye CTH, not CLT; 400 % CFH1 exceeds the CLT series' official 0–200 % — stay within 0–200 % for CLT56. The 20 min dry is for CTH; the Milesi TDS gives 8 h at 20 °C for water-diluted CLT.

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.

Conventional spray

Nozzle
1–1.2 mmrecommended
Pressure · air
2–3 bar at gunrecommended
Consumption
80–100 g/m² ready mixdealer

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
1–1.5 barrecommended
Consumption
10–20 g/m² (TDS figure — appears to be concentrate, see notes)datasheet

The Milesi TDS states 10–20 g/m² for automatic airmix — given the 500–800 % dilution this reads as concentrate, i.e. ~80–100 g/m² of ready mix.

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 carousel

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

Milesi TDS covers automatic rotating (carousel) spray machines at 700–1500 % dilution, 5–20 g/m². This is not electrostatic: the TDS does not mention electrostatic application (per the methods page electrostatic can be combined with any spray type; water dilutions need isolated equipment).

Safety: Composition and hazard class are not published (no CLT56 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.
