Stone, Marble & Concrete Coatings

7620 Stone Coating (penetrative)

Unlike our standard coating for stone 695 (which is a water based topographical coating) this coating is designed to penetrate deep into the structure of the stone. After it has become established in the stone it provides strong hydrophobic and oleophobic protection. Specifically developed for natural stone and cementitious surfaces such as sandstone, limestone, travertine, concrete, pavers and brickwork.

This coating will remain highly effective for approximately 10-20 years. (Top up coatings for areas subjected to high abrasion or repeated cleaning, can be completed in minutes) This coating can be used on floors and on work surfaces including hybrid stone. As the coating becomes enmeshed within the surface structure of the stone it also provides excellent anti-weathering characteristics which significantly impede degradation and water ingress. Testing is always recommended before large scale application. It should not be applied to wet or moist stone. Optimum performance is established after curing for 48 hours at 20°C, however, functionality is established within 2-3 hours.

Case Study

CCM was happy to solve a problem for the town of Penzance, Cornwall / UK where a huge oil stain ruined the newly refurbished Penzance Promenade. An article in Cornwall Live highlighted the problem, noting that all attempts to clean the area had failed so far.
