APT have been providing professional limestone cleaner services for over 30 years, offering their services nationwide. Our fully trained cleaning technicians assess the entire project and create a cleaning plan that ensures minimum disruption to daily routines while leaving the limestone façade sparkling clean. All cleaning, at both high and low levels, is carried out to stringent Health and Safety standards.
APT employs one of the most advanced methods of revitalising any exterior stone, including limestone, which is soda blasting. This method involves firing specially graded sodium bicarbonate crystals against the marble surface using low-pressure compressed air. The crystals are much softer than limestone, so when they come in contact with it, there is no scratching.
Soda blasting works from the outside in. As the crystals impact the surface to be cleaned, they shatter. The energy from this shattering disrupts the surface of the contamination, which is simply blown away in the stream of air and crystals.
This removes successive layers of contamination until the surface of the limestone is reached. Traditional methods rip the entire layer of contamination off in one fell swoop, which can cause damage to the limestone surface.
During the 1990s, low-pressure super-heated steam cleaning systems were developed for cleaning limestone and other stone cleaning tasks. APT’s operatives, working with engineers, took this method to the next level, developing their proprietary low-pressure super-steam system. The super-heated steam cleaning method of providing cleaner limestone has several advantages, such as:
Quick drying: The steam is superheated, and the low volumes of water needed to produce that steam mean that very little water remains on the surface of the limestone after cleaning.
Suitable for all seasons: No water droplets enter any pores or flaws in the limestone surface, reducing the chances of freeze-thaw damage. This method can be used in all seasons.
Low surface pressure: The low surface pressure prevents damage to the limestone.
Kills spores of mosses and algae: High temperatures kill the spores of mosses and algae, meaning that no chemical inhibitors need to be used before or after cleaning to retard re-growth.
In conclusion, APT’s professional limestone cleaner services have been delivering exceptional results for over 30 years. Our experienced cleaning technicians use advanced methods like soda blasting and the heated steam cleaning method to ensure that your limestone facade is left sparkling clean without any damage.
