Effective hot paint stripping – Maximum power for perfect surfaces!
Do you want to remove old layers of paint effortlessly? With our proven hot paint stripping technology, you'll achieve professional results – quickly, thoroughly, and efficiently.
Efficient secure Process stable
Why hot paint stripping?
This method uses high temperatures to dissolve paints and coatings – with less aggressive chemicals. This means less effort, high precision, and a sustainable alternative to traditional paint stripping.

Frequently Asked Questions (FAQ)
What paint stripping processes does WT-DIRECT offer – and when is hot paint stripping the best choice?
We offer solutions for hot paint stripping (thermochemical), cold/chemical paint stripping, and special processes. Hot paint stripping is ideal when dealing with thick coatings , hard/chemical-resistant paints , or time-critical processes – e.g., in industrial cleaning cycles.
What is the difference between hot and cold/chemical paint stripping?
Hot paint stripping: higher temperatures accelerate the degradation of the coating – fast, reproducible, ideal for series production. Cold/chemical paint stripping: operates at lower temperatures, is suitable for more sensitive substrates, but is often slower.
Which materials are suitable for hot paint stripping?
Very good: steel. Suitable with appropriate formulation: aluminum, precious metals, magnesium. For thin-walled or complex geometries, we recommend a preliminary technical inspection .
Which coatings can typically be removed?
These include powder coatings, stoving enamels, 2K systems, kata or wet coatings. For special coatings (e.g., high-temperature or chemical protection), we test material/coating combinations individually.
Which process parameters are important (temperature, time, motion)?
Guideline values: 15–45 minutes – depending on material, layer thickness, and type of paint. Select temperature ranges according to the PDF work instructions ; optionally, movement/circulation supports the exchange of the active ingredient.
How long does a paint stripping bath last? Maintenance & service life
The service life depends on loading, contamination, replenishment , and filtration . Regular checks (pH, conductivity, visual inspection) and separation/filtration of paint sediments increase the service life.
What equipment do I need?
A suitable paint stripping tank/oven , temperature control, possibly circulation system, basket/product carriers, draining zones, and a washing station. We recommend media-resistant baskets for small parts.
What PPE and safety measures are necessary?
Mandatory: Heat-resistant gloves, safety glasses/visor, suitable clothing, and sturdy footwear. Ensure: adequate ventilation , fire protection , temperature limits , and work only according to the manufacturer's instructions.
How do I dispose of residues and rinse water?
Paint sludge and rinsing media are generally considered hazardous waste . Disposal must be carried out in accordance with local regulations via certified waste disposal companies. Safety data sheets (SDS) must be observed.
Does hot paint stripping affect the surface?
With correct parameterization, the geometry is preserved. After paint stripping, we recommend rinsing, neutralizing, and drying to obtain a clean, adhesive surface.
What are typical sources of error – and how do I fix them?
Incomplete paint removal: Adjust time/temperature, check bath maintenance. Residues: Optimize rinsing/neutralization step. Discoloration: Check material compatibility, choose an alternative formula.
Are there any environmental and legal regulations that I need to comply with?
Yes. Relevant environmental, occupational safety, and waste management regulations must be observed. Check site requirements (ventilation/emissions), hazardous material storage, and maintain operating instructions .
How do I start a project – testing & consulting?
The quickest way is with a free consultation and, if necessary, a sample inspection of your parts. We recommend a scale-up check of time/temperature/material before starting series production.
