Polished Concrete: Realistic Expectations & Clarifications

Polished Concrete is a durable and easy-maintenance floor. But its presentation may be inconsistent and can offer a variety of appearances that need to be considered by the site's owner. Read the through the foloowing clarifications to understand the all the steps involved in the Polished Concrete process.

The current condition of the concrete slab will influnce the appearance of the finished product. Any Polished Concrete samples or presentations that you have seen can only offer a general idea of how your finished floor may appear. Stains, cracks, irregular aggregate patterns, floor patches, joints, various shades, and corrosion in the existing concrete will affect the appearance and may affect the finish of the Polished Concrete.

When grinding to achieve exposed aggregate, it is impossible to know the pattern, color and volume of aggregate imbedded beneath the surface of the concrete. The exposed aggregate may be irregular in color, shape and volume, and the final design and pattern is out of the control of PennCoat's installation team.

Dust Control
Excessive dust is an unavoidable by product of polishing concrete. Prior to polishing concrete, we will assess and suggest dust mitigation methods that will help contain and control dust from breaching into unwelcomed areas. Our dust mitigation methods will be limited to what is defined in the scope of work. The owner is responsible for any containment or mitigation that extends beyond the scope of work.

Concrete Repair
Penncoat, Inc. will repair damaged, cracked, pitted concrete and joints to fulfill a flush and level floor. We will make every attempt to match and blend the patches with the surrounding floor. These repairs can be polished with the floor, and offer the same sheen and luster. But they will be inconsistent in color and will appear as distinctive repair markings in the floor.

The polished concrete equipment has access limitations and is unable to serve areas less than 3' wide and 4' tall. Special requests made by the owner to polish areas beyond what is accessible will incur additional charges.

Any future cracking of the polished floor system due to movement of concrete slabs is out of the control of PennCoat, Inc. and therefore PennCoat, Inc. accepts no responsiblity for repairing cracks. Should the Owner/Contractor request PennCoat, Inc. to repair joints; all work will be completed at an additional charge.

Weekly Suggestions - Wet mop with a clean mop using clean water and a lithium silicate* cleaner. Allow the cleaner enough time to suspend the dust and dirt from the floor. Do not let the cleaning solution dry on the surface. If using an autoscrubber, use clean water and a lithium silicate* cleaner. be sure to equip the autoscrubber with nonabrasive polishing pads.
Every 3-6 Months Suggestions - Apply a surface-penetrating lithium silicate stain resistor with a pump spray, and spread with a microfiber mop. Burnish the floor with a high-speed propane Burnisher, equipped with a Diamond-Impregnated 3000 grit burnishing pad.
