By using a similar process to our internal treatments we can provide a service for your external stone that can both deep clean your stone whilst also protecting your stone going forward. By using weighted rotary machines equipped with abrasive cleaning pads we can strip the floor of any previously existing sealants whilst also providing a deep clean of the area to remove algae and organic growth residues present on the surface. Instead of using high pressure equipment we clean all pointing/grout lines by hand. This will prevent any loose pointing from being displaced whilst also cleaning the pointing/grout lines though aggitation. Once we have given the stone a deep clean and allowed the area to dry, we can then move onto the sealing of the stone. It is vitally important to seal your natural stone once restoration is complete, here at Stonelab we have a wide range of sealants specifically designed to suit and protect your stone going forward. For more information on our different sealants, you can find a breakdown of our sealing products on our Sealing and Surface care page.
