CLT48

CLT48 Kromolux dye concentrate, American walnut

Kromolux (made by MILESI) concentrated transparent dye stain with no binder, American walnut shade (going by the name, a warm dark-brown walnut). Very even colour and high strength, so you can go dark and still keep the wood clear and the grain visible. Cut 500–1000 % with solvent thinner (S10/S12/S90) or deionised water, with or without CFH1/CFS1 binder (0–200 %). Mixes with every other dye in the range in any ratio. Per the series TDS it takes polyester, polyurethane and nitro topcoats.

  • Colouring all kinds of wood, veneer or solid
  • Walnut tones that keep the grain visible
  • A base for mixing your own shades with other Kromolux dyes

Mixing matrix

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

    Catalog: fast, strong solvency, for stains on fine-pored timber (beech, birch, maple, alder, cherry are our examples). The dealer calls it 'thinner for PE'.

    500–1000 % means 5 to 10 parts thinner to 1 part concentrate. More thinner = lighter, more transparent shade.

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

    Catalog: medium evaporation, for stains on medium-pored timber. The sensible default (our call). The dealer calls it 'thinner for NC'.

    500–1000 % means 5 to 10 parts thinner to 1 part concentrate. More thinner = lighter, more transparent shade.

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

    Catalog: slow evaporation, for stains on open-pored timber (oak, ash are our examples). On big panels or in hot weather it leaves fewer stripes and blotches (our advice).

    500–1000 % means 5 to 10 parts thinner to 1 part concentrate. More thinner = lighter, more transparent shade.

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

    Listed as an approved thinner on the official pages of the other Kromolux dyes (CLT1–CLT10).

    The CLT48 dealer page doesn't list LZC97. The data comes from sibling pages in the same series (same chemistry). LZC97's own properties are unpublished. Tagged official because the sibling CLT1–CLT9 official pages list it, not because a CLT48 page does.

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

    Water dilution, when you want a solvent-free stain. Deionised water only.

    Dealer note: use only deionised water, or the dye can flocculate and lose colour stability in the can. Water raises the grain, so wet, dry and sand the wood before staining (official wood-prep page).

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

    Spray binder for the solvent-borne system: use it when the concentrate is cut with S10/S12/S90.

    0 % = straight dye, no binder. The binder locks the dye in, cuts bleed into the next sealer coat and evens out absorption. The solvent/water pairing comes from the dealer table (CFH1 / CFS1 = 'solvent-borne / water-borne spray binder').

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

    Spray binder for the water-borne system: use it when the concentrate is cut with deionised water.

    Solvent/water pairing per the dealer table. The official CLT10 page lists CFS1 only.

  • LZC97 / S10Thinner

    MILESI's own suggested solvent cut. Technocolor doesn't sell LZC1000; the nearest swap is fast S10 (our substitution, not MILESI's).

    About 1:10, which gives a light, clear tone. For darker go to 1:5 (dealer minimum 500 %).

  • LZC97 / WATERThinner

    MILESI's water cut: LZC97 acts as a co-solvent, then deionised water.

    Deionised water only (dealer). 8 h before sealing (TDS).

Percentages are per 100 parts of component A.

Sanding between coats
Never sand the stain itself. You cut through the colour on edges. Denib only after the first sealer coat.recommended

15–20 cm from the work, 50 % overlap, gun square to the surface, steady speed. Back off the fluid on vertical panels. Do edges and ends first, then the face.

For production runs (the TDS covers fixed airmix/airless and carousel guns). Skip hand-held airless for stain: too much material, and it blotches.

Process and compatibility

Substrate preparation
Sand solid wood or veneer to P150–P180 (open-pored up to P180, fine-pored P180–P220) and de-dust. If you dilute with water, pre-wet, dry and knock back the raised grain first.recommended

Sanding
Don't sand the stain. The first denib goes on the first sealer coat.recommended
Temperature and humidity
15–25 °C, RH 50–70 %; above ~25 °C use slow S90recommended
Don'ts
  • Don't cut it with tap water. Deionised only (dealer).
  • Don't lay it on in one heavy coat. You get blotches and runs.
  • Don't seal before the solvent or water has fully gone.

Safety: (Generic advice, not from an SDS.) Once cut with S10/S12/S90 it's highly flammable. Spray in an extracted booth, wear an A2-filter respirator and nitrile gloves, keep it away from ignition sources. No SDS found for CLT48.
