How to Remove Paint and Graffiti from Stone and Concrete

Paint spills and graffiti can seriously harm the look and value of stone and concrete surfaces. Their strong pigments penetrate deep into the porous structure, making them difficult to remove with standard cleaning methods.

Why Paint and Graffiti Are So Difficult to Remove

Stone and concrete are naturally porous, allowing paint to bond firmly and embed into micro-pores. Simple scrubbing or common cleaners usually only remove the top layer, leaving behind stubborn shadows or color traces that ruin the appearance of the surface.

Dangers of Mechanical and Aggressive Methods

Techniques such as sandblasting or harsh mechanical scrubbing can permanently damage sensitive stone and concrete surfaces. High-pressure washing can also push paint pigments deeper into the pores, making future removal even more difficult and potentially weakening the material.

Advanced, Eco-Friendly Solution: Logic Clean BT

Logic Clean BT is an advanced bio-based liquid developed specifically for removing paint and graffiti from stone and concrete. Its innovative formulation penetrates deeply into fine pores, dissolving tough pigments and adhesives without harming the underlying material.

Unlike harsh chemical strippers, Logic Clean BT works effectively at the root level — breaking paint bonds from within. It softens even heavy layers of paint and graffiti while preserving the strength and texture of your surfaces. The result is a clean, natural finish that maintains both beauty and integrity.

Step-by-Step Paint & Graffiti Removal with Logic Clean BT

  • Prepare: Remove any surface dust and ensure the area is completely dry.
  • Apply: Spray or brush Logic Clean BT evenly over the paint or graffiti.
  • Dwell: Let it sit for several hours (or longer for thick layers) so the liquid can break down paint bonds thoroughly.
  • Rinse: Rinse the area thoroughly with clean water until all residues are gone. Repeat the process if needed for deep or multiple layers.

After Cleaning: Keep Surfaces Protected

Once the surface is fully cleaned, you can keep it easier to maintain by sealing it with a breathable coating. For exterior areas such as façades and concrete walls, use Logic EX. For indoor areas like decorative stone, kitchens, or bathrooms, use Logic S. Both are eco-friendly, water-repellent coatings that preserve the clean result for a long time.

Case Example: City Wall Restoration

A public stone wall covered with graffiti was cleaned using Logic Clean BT. The paint layers were completely removed without surface damage, revealing the natural texture of the stone. After cleaning, the wall was sealed with Logic EX to make future graffiti removal easier and faster.
