Dry ice blasting for building facade restoration involves using compressed air to propel small pellets of dry ice (solid CO2) at high speeds onto the facade's surface.

Upon impact, the dry ice pellets undergo sublimation, transforming directly from a solid to a gas.

This creates micro-explosions that effectively remove contaminants like dirt, paint, graffiti, and pollutants without damaging the building's surface.

It is a non-abrasive, eco-friendly, and efficient method, preserving the facade's integrity while achieving a thorough clean.
