Reddy Kancharla: How to Resurface Concrete

Resurfacing concrete is simple work that you can accomplish with concrete resurfacing items found at any hardware store. When a concrete slab's surface has cosmetic damages but is otherwise in acceptable condition, Reddy Kancharla believes resurfacing is a viable solution.

Products for Concrete Resurfacing

Concrete resurfacing products often consist of Portland cement, fine sands, polymer modifying chemicals, and other additives that help the surfacer apply easier and distribute over existing concrete surfaces. Reddy Kancharla recommends using them in thin layers ranging from 1/16 to 1/2 inch thick. These specialty combinations are pricey, but they can make an old concrete slab look brand new when used properly.

Concrete resurfacing materials are best for covering the concrete's surface and will only cover the most superficial cracks and pits. For more serious repairs, such as large cracks or mild vertical shifts, Reddy Kancharla suggests patching the areas with a patching solution first. Then, apply a complete resurfacing treatment.

Before You Start

It is vital to remove any loose material from the concrete surface. While a powerful spray from a garden hose and a long-handled scrub brush may suffice, Reddy Kancharla believes a proper pressure washing will get the job done better.

Remove any paint, oil stains, or tree sap from the concrete. Reddy Kancharla suggests using a sealant before resurfacing if you fail to remove the stain completely. The discoloration will flow through the resurfacing layer if it is not sealed.

When applying a resurfacer, it is critical to safeguard expansion joints. To keep the resurfacer from filling in these control joints, Reddy Kancharla recommends using duct tape or weather stripping to mask them.

Instructions:

1. Repair any major damage with another concrete patching compound and let it dry completely.

2. Make a resurfacer mixture.

Apply the resurfacer to a damp surface so that the concrete does not absorb moisture while it cures. Then, allow time for the resurfacer to dry.
