Many friends lay a layer of cement in front of their homes for convenience. While cement floors are convenient, they can easily become sandy over time. If left untreated, the sanding will only worsen, ultimately hindering daily life. To avoid these issues, we should repair the cement floors promptly when sanding signs appear. So, how to repair sandy cement floors? How to prevent them from becoming sandy?

1. Depending on the degree of sanding on the concrete surface, different treatment methods can be chosen. If the sanding is minor and the affected area is small, you can purchase some cement slurry, mix it well, and apply it evenly to the sanded areas on the concrete. Don't apply too much; just ensure it's level. Once the cement dries, it won't affect daily life, though the surface color might appear uneven. This won't hinder our daily use, so if there's no special pursuit of appearance, this method can be used.

2. If the area of sanding is neither particularly large nor small, but at a moderate level, dealing with it using cement slurry is not very convenient. We can purchase some floor treatment agents, mix them with water in a certain ratio, stir well, then apply the mixture to the sanded spots. Keep the area moist for three hours after application. Once it dries, the area is ready for normal use.

3. If the area of the cement floor that has become sandy is large, repair mortar is required for restoration. Before applying the repair mortar, an interface agent should be applied to the sandy areas beforehand. After applying both the interface agent and the repair mortar, if possible, a smoothing and polishing process can be conducted to enhance the floor's luster.
