Fortunately, you don't have to live with flaking concrete, or tear up a damaged yard and pour a new one. Please prepare the surface well before use. Believe it or not, that's all it takes to deal with splinters in the driveway or yard, walkway or garage floor slab. In fact, you can use the respaver to revive almost any worn concrete surface.
Splinters can appear because the rebar has been exposed and moisture and water have started to rust the rebar or because the concrete joints were built incorrectly. As the climate changes, concrete expands and causes it to flake, leading to further deterioration. One technique that can prevent concrete from flaking is to apply a good water sealant to the finished surface to prevent water from entering the concrete. Over the course of a winter, or over the years, as internal pressure increases and decreases, the surface layer of concrete is stressed, which leads to flaking.
Splinters can also be avoided if concrete is handled with care and appropriate techniques are used when pouring, such as providing adequate concrete coverage (embedding) of rebar and placing joints in the right places and at the right distances. If you ignore the flaking, it eventually spreads, compromising the integrity of the surface until it can't be repaired, leaving no recourse other than to tear it off and start over. If you try to coat the concrete without first fixing the deep areas, the facing material will end up lower than the rest of the concrete. Repeating this process over and over again during the winter causes a lot of stress on the concrete and the surface splinters, flakes or pits.
In a bucket, bathtub or wheelbarrow, combine the resurfacing with water in the proportion recommended by the manufacturer. You have undoubtedly seen many concrete sidewalks, floors and patios that have been sprinkled with de-icing salt for years and yet it doesn't splinter. The facing material is simply spread over the existing and chipped concrete surface to create a fresh and flawless finish. Repairing a pitted or peeling garage floor is only intimidating because most people don't know what to use or how to start.
Specially formulated to restore lackluster concrete, resurfacing products like Rapid Set NewCrete (available from The Home Depot) make it quick and easy for homeowners to tackle chipping on their own, without having to hire a contractor. The remedies for chipping vary depending on the severity of the problem, the type and location of the concrete structure and other factors. In order for this stucco to permanently adhere to chipped concrete, the old concrete must be clean and solid, with all the loose concrete detached. In general, the depth of damage is usually less than ¼ for peeling and ½ for some bites.
Concrete peeling occurs mainly in areas where concrete is exposed to freezing and thawing conditions. This type of surface failure, known as chipping or flaking, is more common in colder climates where freeze-thaw cycles and thawing chemicals are prevalent.
