Blue Slate Patio & Stair Restoration

This patio and the stairs beside it had been overtaken by moss and mold. We did a surface clean on it and cleaned off the old wooden retaining wall and the steps, then got all of the old polymer sand out and washed the dirt away. Professional-grade polymer sand went back into all of the open joints to finish it. The wood came out super clean, and you could see the color in the blue slate once again.
