5 step guide to successful paint removal

Required Tools

• Paint remover in a can can be applied with a brush, roller, or spray gun
• Scraper or similar tool
• Water spray, e.g., pressure washer
• Cardboard box for handling small items
• Protective equipment (mask, gloves, safety glasses)

1. Preparation:


• Ensure the paint remover is suitable for your object.
• Choose an appropriate place for processing.
• Cover areas you do not want to treat to protect them from spray mist.
• Note: The substance can damage plastic surfaces.
• Do not use a hot air blower simultaneously with the paint remover, as the flash point of the substance is low.


2. Application:


• Spray or brush the substance onto the surface to be cleaned and let it act for 5-15 minutes. Allow the substance to act longer if the paint surface is thick.
• Always perform a test removal in a small area first to determine the optimal time for paint removal.
• The product can be effective for 0.5-30 hours without the surface drying out.
• Apply the substance in a sufficiently thick layer to prevent the surface from drying out. Add more substance if you notice that the surface has dried out.


3. Removal:


• Spray the surface clean with water, e.g., with a pressure washer.
• Scrape off the paint with a metal spatula. Ensure the object can withstand the scraping.
• The waiting time typically varies from half an hour to eight hours but can last up to 30 hours. Washing must always be done before the 30 hours are up. If necessary, re-treat the surface to remove all the old paint.


4. Repainting the Surface


• Clean the stripped surface thoroughly with water or a suitable cleaning solution to remove any residue of the paint remover.
• Allow the surface to dry completely before applying new paint.


5. Safety


• Wear protective gloves, eyewear, and clothing.
• Avoid inhaling fumes and ensure proper ventilation.


Following these steps will help you effectively remove old paint and prepare the surface for a fresh coat. Paint removal is a cost-effective and relatively easy way to update an old, worn surface.
