Application
Brush
- Tool
- natural stiff-bristle brushdealer
- Coats
- 2dealer
- Sanding between coats
- normally not needed; if grain raises, knock back lightly with P180–P240 or a grey pad before coat 2 and de-dustrecommended
Work it evenly into the wood; leave no puddles or runs.
Roller
- Coats
- 2dealer
Apply by roller, working it in evenly; after 15–30 min wipe off the excess with a clean dry rag.
Cloth or pad
- Why ru
- Этап снятия излишков ветошью — по данным дилера; само нанесение ветошью стандартно для протирочных масел такого типа, но Technocolor этого не указывает.
Rag-off of excess 15–30 min after each coat is mandatory. Applying with a rag/pad is fine on small parts.
HVLP
- Recommended
- norecommended
Not recommended — the maker only lists brush/roller. Spraying is acceptable only for pre-finishing loose boards in a booth, followed by working in and wiping off.
Process and compatibility
- Substrate preparation
- degrease, sand to P100–P120, de-dustdealer
- Sanding
- P100–P120 before applicationdealer
- Temperature and humidity
- 10–35 °C, wood moisture 8–12 %, good ventilationrecommended
- Don'ts
- Don't use the sauna for bathing for 14 days after oiling (recommendation).
- Don't leave surplus oil — wipe off after 15–30 min.
- Don't just bin oily rags, clothing or sanding dust — spontaneous combustion risk: sealed metal container, covered with water.
- Don't pour down the drain.
- Don't work without gloves and ventilation.
Storage
- Conditions
- in the tightly closed original can, cool and dry, out of direct sun; keep the lid on during and after use to stop it drying and skinningdealer
Safety: Wear gloves and ventilate. Spontaneous-combustion hazard: put oily rags, clothing and sanding dust into a sealed metal container, cover with water and dispose of. Keep away from flames and sparks; avoid skin and eye contact, rinse with water if it happens. Keep away from children, do not swallow, do not pour down the drain.
