Paint stripping • Surface preparation • Technical consultancy

Industrial stripping

Paint removal and metal surface preparation with standardised procedures, a strong safety focus, and consistent results.

Our services

Tailored solutions for metalworking and industrial manufacturing — from prototypes to production batches.

Chemical paint stripping

Formulated chemical systems that remove paint while protecting the substrate, with operational safety, repeatability, and reduced environmental impact in mind.

Chemical paint stripping

Surface preparation and cleaning

Controlled, uniform finishes compatible with painting, coating, bonding and other downstream treatments.

Surface preparation and cleaning

Technical consultancy

Support on process selection, trials, acceptance criteria and hands‑on implementation.

Technical consultancy

Materials We Work With

Case-by-case assessment for mixed or sensitive alloys, including trials when needed.

Aluminium Iron and Steel Mixed or Sensitive Alloys

How We Work

A simple, controlled workflow designed to reduce risk, lead time, and rework.

Technical assessment

  • Substrate identification and alloy sensitivity screening
  • Coating type (powder, liquid, primer, clear coat) and thickness
  • Finish specification and downstream compatibility constraints

Output: a technical proposal with the safest and most predictable process route.

Trial (when applicable)

  • Test on a representative sample with controlled parameters
  • Fine-tuning of time, concentration, and washing sequence
  • Acceptance criteria definition (visual, adhesion, compatibility)

Output: validated parameters before scaling to a batch.

Process execution

  • Stripping using systems designed for safety and reproducibility
  • Cleaning and surface preparation to ensure uniformity
  • Operational records and SOPs to keep batches consistent

Output: a clean, predictable surface ready for the next step.

Control and delivery

  • Final inspection and surface condition verification
  • Packaging/storage conditions to prevent re-contamination
  • Clear handover notes and handling recommendations

Output: less rework, less variability, and more control in your process.

Frequently asked questions

Quick answers to the most common questions before starting a service.

We work with a broad range of coatings (e.g., powder coating, liquid paints, primers and clear coats). The initial assessment confirms the best solution and sequence for your parts.

Yes, provided the right chemistry and controlled parameters are used. For critical cases, we recommend a trial to validate compatibility and surface finish.

When risk is higher (unknown coating, sensitive alloy, strict finish requirements), a trial reduces variability and rework before scaling up.

It depends on part geometry, coating type, and volume. After assessment, we provide a clear lead time aligned with your urgency.

We prioritise controlled processes, safe handling practices, waste minimisation, and careful solution selection — maximising performance without compromising operational safety.
