No, hairline cracks in concrete are generally not a problem as they do not impact the strength and longevity of the concrete. Generally, cracks less than 0.3 millimeter wide don’t impact the structure. Hairline cracks can grow over time and weaken the structure, such as in a home foundation. Some hairline cracks can also cause leaks in a foundation. It’s important to watch the cracks to see if they grow. Contact a concrete contractor if you notice cracks exceeding 0.3 millimeter wide.

You can use epoxy-based concrete fillers to repair small cracks and dents in the floor. For larger damages, remove any debris, then patch the cracks or holes with concrete repair products or resurface the entire floor. We recommend using fast-curing products that cure in four hours. You can also buy a pre-mixed concrete patch and leveler if you are only repairing parts of your floor.

Concrete resurfacing is the process of applying a new, thin layer of concrete over an existing concrete slab to enhance its appearance and durability. The terms 'concrete resurfacing' and 'concrete overlay' are often used interchangeably, though the exact meaning can vary between contractors. Generally, both refer to applying a layer of pre-blended concrete, typically between 1/4-inch and 1-inch thick. Some contractors may use 'overlay' to describe a thicker application that adds structural integrity, while 'resurfacing' might refer to a thinner, more cosmetic layer. This process is a cost-effective alternative to completely replacing the concrete, as it uses significantly less material than pouring a new 4-inch slab. Resurfacing also provides an opportunity to add new colors or stamped textures. Other names for this process include concrete restoration, concrete refinishing, and concrete rejuvenation.

You can dry pour concrete over existing concrete, but it’s best to use wet pour concrete instead. Dry pour concrete is easier to apply, but in order for new concrete to adhere to old concrete, it needs the right mixture for slow, uniform curing. Additionally, dry pour concrete is less durable and less resistant to cracking and concrete sinking, so dry pouring over an existing slab may result in surface imperfections appearing prematurely.
