Graffiti and spray paint on brick, concrete, and metal facades are a common headache. GBL rapidly penetrates alkyd and acrylic paint layers, dissolving organic binders without harming the underlying stone masonry.
Application on Mineral Surfaces
Apply GBL using a brush. After a 3 to 5 minute dwell time, loosen softened paint with a stiff brush and rinse thoroughly with high-pressure water.
Safety Tips
Always wear eye protection and gloves, and mask off adjacent sensitive plastic or painted trim to avoid accidental contact.
