What Methods of Limestone Cleaning do you offer?

Soda Blasting – Cutting-Edge Limestone Cleaning

Our cutting-edge approach to limestone cleaning involves soda blasting, a method that sets us apart. Specially graded sodium bicarbonate crystals are propelled against the limestone surface using low-pressure compressed air. These crystals are significantly softer than limestone, ensuring zero scratching upon contact.

Soda blasting operates from the outside in. As the crystals impact the surface, they shatter, releasing energy that disrupts the contamination’s surface. This loosened contamination is effortlessly carried away by the stream of air and crystals.

This method ensures that successive layers of contamination are removed until the pristine surface of your limestone is revealed. In contrast, traditional methods often strip away the entire contamination layer at once, risking damage to the limestone surface.

Low-Pressure Super-Heated Steam Cleaning for Pristine Limestone

In the 1990s, low-pressure super-heated steam cleaning systems were introduced for limestone and other stone cleaning tasks. APT has taken this method to the next level, developing our proprietary low-pressure super-steam system, an ideal choice for cleaner limestone. This method offers several advantages:

Quick Drying: The superheated steam ensures rapid drying, leaving minimal residual water on the limestone surface.

All-Season Usability: Our method prevents water droplets from entering pores or flaws in the limestone, reducing the risk of freeze-thaw damage. It can be applied year-round.

Low Surface Pressure: Our low surface pressure approach safeguards your limestone from damage.

Moss and Algae Prevention: High temperatures effectively eliminate moss and algae spores, eliminating the need for chemical inhibitors before or after cleaning.

Cleaning limestone requires expertise and the right methods to ensure the stone’s longevity and beauty. When it comes to limestone cleaning, rely on APT’s decades of experience and advanced techniques.

Soda Blasting: APT employs soda blasting, an advanced method to clean limestone effectively.
