Removing old paint from a wall or other surface is a process that requires the right approach and tools. Here are the main methods that can be used:
1. Mechanical method
Suitable for most types of surfaces, such as wood, metal or concrete.
What you need:
Spatula or scraper;
Abrasive paper or sander;
Metal brush (for rough surfaces).
Steps:
Use a putty knife to remove loose paint.
If the paint is very strong, use a sander or sandpaper to remove the paint to the base.
For metal surfaces, use a wire brush or a drill with a brush attachment.
2. Chemical Method
Suitable for complex or large surfaces. Use special paint strippers.
What you need:
Chemical solvent or paint stripper;
A brush for applying the stripper;
Gloves and safety glasses.
Steps:
Apply the chemical solvent to the surface with a brush.
Wait 15-30 minutes (the time is indicated on the package) for the paint to soften.
Remove the softened paint with a putty knife.
After work, wash the surface with water or a solution to remove chemical residues.
Important: Work in a well-ventilated area or outdoors.
3. Heat method
Effective for wooden surfaces.
What you need:
A hair dryer or heat gun;
A spatula.
Steps:
Direct hot air to the surface area to soften the paint.

Important: Be careful not to overheat the surface, especially if it is wooden.
4. Combined method
If the paint is very old or the surface has a complex texture, several methods can be used.
First, treat the surface with a chemical solution.
Then use a mechanical method to remove the remaining paint.
Recommendations
Always use protective equipment: gloves, a mask, and glasses.
Prepare the work area by covering the floor with plastic.
If the paint contains lead (old coatings), avoid sanding to avoid inhaling toxic dust.
