Is your limestone cladding looking jaded?
Are your limestone architectural features in need of cleaning?
If so, you should call APT to benefit from the best limestone cleaning.
Our fully trained cleaning technicians will first assess your needs across the whole project. They will put together a cleaning plan that will leave your limestone façade sparkling clean with minimum disruption to your daily routine. All cleaning at both high and low level is carried out to stringent Health and Safety standards. Now you can benefit from one of the most advanced methods of revitalising any exterior stone including limestone – soda blasting. Specially graded sodium bicarbonate crystals are fired 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 the contamination until the surface of the limestone is reached. Traditional methods rip the entire layer of contamination off in one fell swoop, will cause damage to the limestone surface.
During the 1990s, doff low pressure steam cleaning systems were developed for cleaning limestone and other stone cleaning tasks. Here at APT, our operatives, working with engineers, took this method to the next level, developing our proprietary ‘Hot Box’ low pressure high steam system. As well as being highly controllable, it is significantly labour-saving so you can benefit from quicker and lower cleaning costs. The Hot Box method of limestone cleaning has other advantages too:
Quick drying as the steam is super heated 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
Can be used in all seasons as no water droplets enter any pores or flaws in the limestone surface reducing the chances of freeze-thaw damage
Low surface pressure prevents damage to your limestone
High temperatures kill the spores of mosses and algae meaning that no chemical inhibitors need to be used either before or after cleaning to retard re-growth
Case studies coming soon…
“I would like to thank the team at APT for the hard work and flexibility in delivering this project on time and in overcoming some of the abnormalities suffered with recent weather and on-site movements of contractors. The result was outstanding, and I look forward to working with you in the future on similar projects.”
