PWO method

To maintain the long-term aesthetics of stone materials and to restore and preserve their impaired design quality.

Our company operates under the concept that "natural stone is alive and breathing!" We offer the 'PWO method,' which ensures that the design of natural stone is not compromised and that it continues to breathe during installation. We address issues such as erosion from acid rain, soot, and other aging factors, as well as the removal and prevention of stains, wet marks, yellowing, and efflorescence. Using our own cleaning agents, we restore the aesthetic appeal of the stone without compromising its texture, and with our proprietary coating agents, we can prevent recurrence and maintain long-term beauty. [Case] ■ When you are troubled by stains - Wet color stains (rising) - Aging weathering (loss of luster) *For more details, please download the PDF or feel free to contact us.
