Polished concrete is a multi-step process where the concrete floor is mechanically ground, using heavy-duty machinery equipped with progressively finer grits of steel, semi-metal, and diamond-impregnated pads that rotate in a multi-vortex pattern. Dual rotors beneath the machinery rotate the diamond pads in a multi-orbital planetary rotation, meaning they revolve the opposite way on their own axis, gradually grinding the surface down to the desired degree of shine and smoothness.
The process is as follows:
GRIND: First, we grind the top layer of concrete, stripping and removing minor pits, blemishes, stains, or light coatings from the floor.
HONE: Next, we hone the surface using several passes of finer grit diamond pads. Each grit level passes 3-4 times before moving on to a finer grit. Grit levels range from 30, 50, 70, 100, 150, 200, 400, 600, 800, to 1800. The finer the grit, the higher the shine.
POLISH: Finally, an integral impregnating sealer is applied to protect, the porous concrete from spills and other chemical intrusions. Using non-diamond polishing pads, we perform several passes over the floor to burnish away the final layer of porosity and reveal the beautiful colors and textures of the concrete underneath.
Routine maintenance consists of daily dust mopping with a microfiber pad to remove dirt and grime. Wet mopping is also needed, using clean water and a neutral floor cleaning solution to loosen and remove dirt particles.
