CLT5

CLT5 Kromolux wood dye concentrate, medium walnut

Concentrated transparent wood dye (stain) without binder, Kromolux series, medium-walnut shade. Very even colour and high strength: goes dark while staying see-through and keeping the grain. Reduce with water or solvent, with or without binder. Overcoat with polyester, polyurethane or nitro lacquers.

  • Walnut-toning any species — veneer and solid
  • Furniture, mouldings, frames, general joinery — spray
  • Shade matching with other CLT dyes (with CLT4 to go darker, CLT6 lighter)
  • Evening out sapwood/heartwood colour under a walnut tone

Mixing matrix

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

    Catalog: fast, strong solvency — stains on fine-pore timber (beech, birch, maple, alder etc.). Dealer calls it 'thinner for polyester'.

    More thinner = lighter shade. For medium walnut on pale timber 700–1000 % is usually plenty; on darker timber or for a richer tone go nearer 500 %.

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

    Catalog: medium evaporation — stains on medium-pore timber. Dealer calls it 'thinner for NC'. Technocolor's schedules for the CTU transparent dye use S12.

    More thinner = lighter shade. For medium walnut on pale timber 700–1000 % is usually plenty; on darker timber or for a richer tone go nearer 500 %.

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

    Catalog: slow evaporation — stains on open-pore timber (oak, ash, anegre). Dealer: 'slow dye thinner'. A slow thinner also helps on big panels and in heat — fewer stripes and lap marks (shop practice).

    More thinner = lighter shade. For medium walnut on pale timber 700–1000 % is usually plenty; on darker timber or for a richer tone go nearer 500 %.

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

    Water-reduced stain: raises the grain more (official wood-prep page: raise the grain beforehand), dries slowly — TDS: 8 h before overcoating.

    Deionised water only — tap water makes the dye flocculate and hurts colour stability (dealer note). Per TDS, CLT10 (white) cannot be water-reduced — keep it out of a water batch.

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

    Listed on the official CLT5 page alongside S10/S12/S90/water. In the Milesi TDS LZC97 is in the thinner list and in both suggested dilutions goes in WITH the main thinner (0.5 part with LZC1000, or 1 part with water, per part of dye), never alone; calling it a coupling solvent is our interpretation.

    The dealer table does not list LZC97.

  • LZC97 / LZC1000Thinner

    Manufacturer's (Milesi) suggested solvent dilution.

    LZC1000 not found in the Technocolor range; TDS also lists LZC1024 and LTC5. Nearest Technocolor equivalent by purpose is S10/S12.

  • LZC97 / WATERThinner

    Manufacturer's suggested water dilution.

    Deionised water.

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

    Binder for solvent-reduced batches (S10/S12/S90). Adds film-former to the stain so the primer drags less dye and end grain colours more evenly (shop practice).

    Zero binder is fine too. The dealer writes 'CFH1 / CFS1 — binder ОР (solvent) for spray / binder ВР (water) for spray': read positionally that makes CFH1 solvent and CFS1 water, but Technocolor schedules show the opposite (CFS1 + S12 with CTU; CFH1 + water with water-borne CTH), so CFS1 = solvent, CFH1 = water is assumed. Confirm on the can label.

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

    Water-based spray binder — when CLT5 is reduced with water.

    Don't put CFH1 into a solvent-reduced batch. The schedule at otdelka-stoleshnits-oblitsovannyh-shponom-buka-pu (page actually shows 'Open-pore finishing of oak kitchen fronts (Acr.)') uses CTH 100 : CFH1 400 : water 1000 — CLT5's official CFH1 cap is 200 %.

  • CFS1 / S12Additive
    % by weight: CLT5 100 : CFS1 150–200 : S12 500 parts by weight %

    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, 80–100 g/m², 5 min at 20–25 °C) and 'Mouldings and frames (UV)' (CTU 100 : CFS1 150 : S12 500, 80 g/m², 5 min at 25–30 °C) schedules name CTU, not CLT; CLT5 is the same class (transparent concentrate; the catalog gives CTU the same S10/S12/S90 500–1000 % and 80–100 g/m²).

  • CLT4 / CLT6 / CLT7 / CLT1..CLT19Additive
    % by weight: any ratio %dealer

    Shade matching: all dyes in the series intermix in any ratio.

    Blend concentrates before thinning; test on an offcut of the same timber under the same topcoat. CLT10 (white) cannot be water-reduced (TDS).

Percentages are per 100 parts of component A.

Process and compatibility

Substrate preparation
Sand flats P150–P180–P220, profiles with K60–K80 mats/pads or brushes (Technocolor stain schedules); de-dust. Coarser grit = more uptake and darker, finer = lighter (official wood-prep page). End grain goes darker (CFS1 binder helps — shop practice). For water-reduced stain, wet the wood, dry and fine-sand to raise the grain first (official wood-prep page).schedule

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: No SDS found. The concentrate is presumably solvent-based (density ~0.965, takes solvent or water) — treat as flammable: spray in a booth with extraction, A-filter respirator, nitrile gloves. Stains skin and clothes badly. (general practice)
