Monument Cleaning – Historical

Structures large and small are an important part of our country’s great historical past and give knowledge and understanding to generations that follow. Over the years, pollution from the air plus moss and lichen build up on the stonework of monuments meaning that they will need cleaning at some point. The cleaning and restoration of these historical monuments is a vital part of preserving our UK heritage.

However, monument cleaning is a specialist area – much harm can be caused if stone cleaning is not carried out properly. As a manager needing to clean a scheduled ancient monument, one of the biggest problems you face is to decide whom you can trust to clean the monuments in your care without causing damage.

And that’s where APT come in…

Monument Cleaning Equipment And Techniques

To restore and preserve these structures we use the same cutting-edge stone cleaning and masonry restoration techniques and equipment as for listed building restoration and renovation including:

Doff and Hot Box Super-Heated Steam Cleaning
Soda Blast Cleaning
Torc Cleaning
Poultice Cleaning
• Chemical Cleaning (where required)

Having the right tools and the latest equipment at our disposal enables us to carry out restoration of all stone surfaces to pristine condition including delicate materials such as marble, limestone, sandstone, all masonry including historic bricks and all metals including bronze statues.

For all sensitive surface cleaning of stone and masonry to remove staining, dirt and other atmospheric pollution, surface contaminants (including unwanted paint coatings or graffiti) we use our Vortex II Spinning Blast Bead for either wet or dry applications. APT uses this on all brick and stone surfaces including York stone, sandstone, Portland stone, and all marble and terrazzo. We safely use Soda Blast Cleaning to clean all metal monuments including bronze and brass statues.

Doff cleaning, Hot Box and Torik Super Heated low water pressure high steam temperature cleaning systems are used to clean stone and masonry. They are particularly effective when used to remove organic growth, such as moss, algae and lichens from surfaces without the use of chemicals as the high temperatures kill any spores, inhibiting the start of re-growth.

Stone Restoration Using Chemical Methods

Stone and Poultice Cleaner is used for super sensitive cleaning applications to draw out the surface contaminants.

We have also developed an Eco friendly range of safe chemical cleaning solutions and treatments to assist where required on cleaning applications for all surface types here.
