Basement concrete cracks as a house settles. Hopefully most of the cracks are minor but you should patch these cracks then apply a concrete sealer. Resurfacing concrete finish is not just for looks. Water and possibly radon gas will seep through these fissures. Remove any lose pieces of concrete and debris with the trowel hand tools. Pressure wash the concrete. You must get the area as clean as possible. Use concrete with at least 3,000 PSI and good adhesion. The concrete patch mix comes with its own bonding agent. Follow the manufactures instructions carefully. When these patches are cured you will be ready for resurfacing concrete for the floor.
There are a number texture resurfacing concrete material designed for resurfacing, overlaying and texturing stable concrete floors and surfaces. They are high strength, toppings that come as a “just add water” overlay mix for creating thin stamped overlays, patching or levelling and they give you a textured finish and serve as a concrete sealer. These are the thicker coatings. Then there are the thin topping material designed for resurfacing, overlaying and texturing stable concrete floors and surfaces of your basement concrete. These coatings come in standard colors but can be custom colored for additional highlighting effects. There is some texture to this coating. For a smooth finish use the super thin cementation materials that are designed for creating an extremely smooth finish to the top is a “just add water” overlay mix for creating smooth finishes. The good ones are polymer emulsion compositions and blends that when mixed with the correct ratios of white cement, various silica quartz aggregates and other components create permanent, not temporary coatings.
If your basement concrete is smooth but drab, there are spray-on or roll-on concrete sealers that will beautify as well as seal the concrete. Resurfacing concrete this way is relatively fast and easy and give you a nice finish. It is wise for health reasons to apply a concrete sealer even if you plan to erect finished walls and hide the basement walls.
