Cleaner Hempel Pre-Clean 1 L — Hempel pre-cleaning liquid for surface preparation, 1 l

Hempel Pre-Clean 1 L is a pre-cleaning liquid formulated for surface preparation before painting or coating. This 1‑litre product removes grease, oil, dust and general contaminants from metal, wood and previously coated substrates, helping to optimise adhesion and ensure a consistent finish. It is intended for maintenance, refurbishment and new coating applications where a clean, degreased surface improves overall coating performance.

Advantages

Hempel Pre-Clean quickly dissolves and removes common surface contaminants without mechanical abrasion, reducing preparation time. The liquid is suitable for a range of substrates, enabling uniform surface condition across metal, wood and painted surfaces. Its formulation supports improved adhesion of subsequent primers and topcoats, contributing to longer-lasting results when used as part of a proper surface-preparation routine.

Suitable for

• Preparation of metal surfaces before priming or painting
• Cleaning wooden surfaces prior to sanding and coating
• Degreasing previously coated surfaces during maintenance or refurbishment
• Pre-treatment of areas where oil, grease or dirt may impair coating adhesion

Key specifications

• Form: liquid for wiping or spraying
• Volume: 1 litre
• Suitable substrates: metal, wood, previously coated surfaces
• Primary function: removal of grease, oil, dust and contaminants
• Application: surface preparation prior to painting or coating

How to use

Ensure the surface is cool and free of loose dirt or rust. Apply Hempel Pre-Clean to a clean cloth, sponge or low-pressure spray and wipe or spray evenly across the area to be treated. Allow the liquid to dissolve contaminants, then wipe off with a clean, dry cloth. For heavily soiled areas, repeat the procedure until contaminants are removed. After cleaning, allow the surface to dry completely before proceeding with sanding, priming or coating according to the coating manufacturer’s instructions.

Usage recommendations

Use appropriate personal protective equipment (gloves and eye protection) and ensure adequate ventilation during application. Test on a small inconspicuous area if compatibility with an existing coating is uncertain. Follow local disposal regulations for any used cleaning materials and empty containers.
