- Cover the treated section with plastic film or sheet to keep the paint stripper from drying too quickly.
- After some hours, remove the plastic and try to scrape the paint with a bladed paint scraper.
- If the paint is still stuck fast, allow more time for it to work.
- If you are able to lift the paint off, move ahead and begin applying paint remover on the next section.
- Collect the scraped paint material in a bucket and make sure to dispose as hazardous waste.
- Use a scrubbing pad for places that are hard to reach.
- Repeat the procedure if needed.
After successfully stripping the paint you can:
- Wash residue off carefully, wash it down with detergent, and dry the surface.
To prepare it for following steps, ensure it will not corrode, and completely remove all the paint and solvent:
- Go over the part with an abrasive pad/ steel wool or electric sander.
Depending on the type of metal and the intended follow-up coating, abrasive sandblasting is the next step of treatment to ensure ideal adhesion before applying paint or powder coating in the colour and finish of your choice.
