Keep traffic away from the patch until it has properly cured. When the new concrete has set, but before it fully hardens, smooth the surface or add texture to match the surrounding area. Smooth the repair with a trowel, and scrape away any excess, leaving behind a smooth surface. If the crack is large, use a trowel scoop up the concrete, and fill the hole. If the crack is narrow, use a masonry crack filler to squeeze the concrete mixture into it. Leaving air in the mixture will weaken the repair. Tamp the mixture down to bring any air bubbles to the surface. If you’re using regular concrete, add a bonding agent to the mix, or apply concrete adhesive to the sides of the crack. When filling in cracks and holes in your concrete, you need to use a vinyl patching compound that will adhere to your existing slab. Clean the space out again, and let it dry before you begin your repair. This will give your new concrete a firm hold so the repair will last longer. Hollow out the damaged area with a chisel, trying to make the opening a little smaller than space underneath.

There are many more advantages to a RenuKrete installation. Luckily, there is R enuKrete! RenuKrete works existing cracks into the resurfacing design of the new structure that resembles natural stone, while completely transforming the look of your deck, patio, walkway or even porch. Oftentimes a patched up crack looks just as bad - or worse - than the crack itself! Also, a 100% texture and color match is usually not possible, and so patching up cracks becomes very unsightly. However, further cracking due to soil and gravel shifting underneath can't be prevented by this method. This material - if used correctly - may prevent further cracking by keeping water and ice out of the crack. Most home and property owners are unhappy with traditional ways to "fix" cracks: mostly the cracks are patched up with filler material. Expansion joints reduce the likelihood of cracks, but cracks can't be completely avoided in most concrete patios or decks. If the slab can't carry its own weight in a section, a crack occurs.
