Safer indoor stripping - with a non-toxic water-based formula

Formulated as a thickened, water-based solution that avoids traditional chlorinated solvents and reduces hazardous fumes; low odour further cuts nuisance smells. The paste consistency concentrates active ingredients on the painted layer rather than running away.

Lower ventilation and handling concerns compared with solvent-based alternatives, making it suitable for small workshops and indoor work. Safer chemistry also simplifies storage and cleanup routines.

Neater application - with a thickened no-drip paste

Thickened consistency prevents runoff and dripping, so the remover stays where applied and acts directly on the coating. Coverage guidance states around 2–3 square metres per 500ml when used as directed.

Precision application reduces waste and mess, useful when working on trim, frames or furniture. Economical performance suits patch repairs and detailed restoration tasks.

Easy cleanup and low odour - with a water-rinse formulation

Water-based chemistry allows residues to be removed with water rather than solvents, and the low odour formulation limits strong smells. User feedback highlights easy wash-off after the stripping process.

Simplifies finishing steps and avoids lingering solvent fumes in enclosed spaces. Useful for hobbyists stripping miniatures and small parts where strong smells would be a problem.
