CTS4
CTS4 solvent-soluble dye toner, brown, for adding to lacquer
Solvent-soluble (ОР) brown dye toner that goes straight into the lacquer. Clear and bright: it doesn't hide the grain, it tints the film and gives the finish more uniform colour and brightness. Compatible with polyurethane, nitrocellulose and acrylic finishes. Dose 0.5–1 % into the lacquer, added just before use; applied by spraying.
- Toning clear PU, acrylic and NC lacquers at 0.5–1 %
- Evening out colour and adding brightness to the finish
- Toning the acrylic topcoat ATL20 + C40 + S80 + CTS 0.5 % over patinated oak (official schedule)
- Toning the PU topcoat PTL61 + C61 + S70 + CTS 0.5 % on veneered worktops (official schedule)
- Colour-matching a stained piece with light passes of tinted lacquer (workshop practice, not from a source)

Into PU, acrylic and NC lacquers. Add just before use and stir thoroughly.
Past 1 % the colour muddies fast and swings with film thickness; get the depth from a stain and just fine-tune with CTS.
Open-pore oak kitchen fronts (acrylic): topcoat over CQS patina, 150 g/m², dry 1.5 h at 30–35 °C.
The schedule doesn't name the CTS colour — pick it to suit (brown CTS4 for warm walnut-ish oak).
Beech-veneer worktops (PU; the page heading on the site is a copy-paste of the oak schedule): topcoat over PTS60 + C26 + S50, 150 g/m², dry 1.5 h at 30–35 °C.
Here the base colour comes from CTH water dye + CFH1 + water (80–100 g/m²); CTS in the topcoat evens it out.

- Coats
- 1 tinted coat, normally the last or second-to-last; build colour with extra light passes rather than more dyerecommended
Spray application (dealer). Don't sand through a tinted coat — edges go pale instantly. Keep any denib light (P320–P400), or do the sanding before the tinted coat.

Process and compatibility
- Substrate preparation
- per host lacquer system; base colour from a stain first (CGS glaze in the oak schedule, CTH water dye in the beech schedule), CTS only to fine-tune in the topcoatschedule
- Goes into
- ATL20, PTL61
- Sanding
- sand the coat before the tinted one; after the tinted coat only light denib P320–P400, never cut throughrecommended
- Temperature and humidity
- as host lacquer; schedule forced dry 30–35 °Cschedule
- Don'ts
- Don't go above 1 % — the colour muddies and swings with film thickness
- Don't add to water-borne lacquers — use the CTH series there
- Don't make up tinted lacquer in advance — add the dye just before use
- Don't spray unevenly: every extra overlap shows as a darker stripe
Storage
- Packaging
- 1 Ldealer
- Shelf life
- check label; typically 12 months in the sealed tinrecommended
- Storage temperature
- +5…+30 °C, sealed, away from heat and flamerecommended
Safety: Not published. Solvent-borne dye — flammable liquid: use in an extracted spray booth, wear an organic-vapour (A2) respirator and nitrile gloves, keep away from flame.
