Frequently Asked Questions

AI
White spirit is a mild solvent primarily used for thinning oil-based paints and cleaning brushes. Cellulose thinner is much stronger and faster-evaporating, designed specifically for nitrocellulose lacquers and primers. Using the wrong type can ruin the paint finish or fail to clean effectively.
Low-odor white spirits and similar products are formulated to reduce volatile organic compound (VOC) emissions, making them less pungent. However, they still require adequate ventilation. Always check the safety data sheet and wear appropriate protective gear when using any solvent indoors.
Used thinners become hazardous waste once contaminated with paint residues. Never pour them down drains or into general trash. Allow residues to dry in a well-ventilated area if possible, or take the sealed containers to a local household waste recycling centre for chemical disposal.
