The first step is pounding the concrete, based on the homeowner’s chosen degree of the exposure uniformity. The finished floor’s level of consistency depends on the aggregate distribution in the concrete. The next step after achieving the specified level of aggregate exposure is using finer grinding pads to polish the concrete. Finally, a sealer is applied after smoothly polishing the concrete.

Non-slippery polished concrete floors can also be achieved for outdoor areas, such as pools. Homeowners who don’t want to the exposed aggregate appearance can choose a final finish that doesn’t reveal any stone. This is made by controlling the degree of grinding.

When working on old concrete slabs, the concrete is usually ground and polished depending on the floor’s condition and the amount of damage. For new concrete slabs, concrete suppliers typically offer a variety of cement colors. Homeowners can also choose from a selection of aggregate types, colors sizes and minerals for the topping mix, or they can choose to have their polished concrete floors colored if they plan to lay new slabs.
