Application
Brush
- Consumption
- 10–15 m²/L per coatdealer
- Consumption
- 60–90 g/m²recommended
- Coats
- 2dealer
- Flash-off
- 5–10 mindealer
- Recoat
- ≥ 12 hdealer
Natural stiff-bristle brush; work the oil in evenly. Wipe off the excess with a dry clean rag after 5–10 min. Second coat no sooner than 12 h later, wipe off again after 5–10 min. Full dry at least 24 h.
Roller
- Consumption
- 10–15 m²/L per coatdealer
- Coats
- 2dealer
- Flash-off
- 5–10 mindealer
- Recoat
- ≥ 12 hdealer
Roll on thin and even, then wipe off the excess with a rag after 5–10 min. Clean the roller with S60.
Cloth or pad
- Flash-off
- 5–10 mindealer
The rag step is mandatory: wipe off excess 5–10 min after every coat. Rag/pad application on small parts also works (our suggestion).
HVLP
- Nozzle
- 1.3–1.5 mmrecommended
- Pressure · air
- 1.5–2 barrecommended
- Pressure · fluid
- 0.3–0.8 barrecommended
NOT an official method (maker lists brush/roller only). If you do spray: one thin coat, then always wipe off the excess after 5–10 min. Good extraction needed — oil mist settles on nearby work.
Process and compatibility
- Substrate preparation
- Degrease, sand to P100–P120, remove dust.dealer
- Sanding
- P100–P120 before oiling; between coats not specifieddealer
- Sanding between (derived)
- if the grain raises after coat 1, a light pass with P240–P320 or a fine non-woven pad, then de-dustrecommended
- Temperature and humidity
- 10–35 °Cdealer
- Maintenance
- refresh as needed once a year with one coatdealer
- Don'ts
- don't leave excess oil on the surface more than 5–10 min — it goes tacky and blotchy
- don't recoat sooner than 12 h
- don't thin more than 5 % S60
- don't tint more than 5 % CL paste
- don't apply below 10 °C or above 35 °C
- don't leave oily rags balled up — lay flat to dry outdoors or soak in water in a closed metal can (spontaneous combustion risk)
- Rags: fire risk
- oily rag spontaneous-combustion warningrecommended
Storage
- Storage temperature
- tightly closed original container, cool dry place, out of direct sunlightdealer

Safety: Keep away from flames and sparks. Wear gloves, avoid skin and eye contact; rinse with water if exposed. Keep out of reach of children, do not swallow, do not pour down the drain.
