To treat scaling on concrete floors, first clean the surface using a high-pressure water jet to remove loose particles. Repair cracks and damaged areas with a concrete repair mixture, ensuring a smooth finish. Apply a penetrating sealer or epoxy coating to prevent future scaling. Regular maintenance, including periodic inspections and reapplying sealants every 1-3 years, is critical for long-term protection.

Scaling on concrete floors occurs due to the erosion of the surface layer caused by chemical reactions, weathering, or mechanical wear. The top layer, rich in cement and sand, dissolves or disintegrates, exposing reinforcing steel and weakening structural integrity. A 2021 study by the American Concrete Institute (ACI) found that scaling reduces concrete’s compressive strength by up to 30% and increases permeability, accelerating corrosion. High-pressure cleaning effectively removes scaling by dislodging loose material without damaging the underlying substrate, as recommended by ACI 561.1R-14. Repairing damaged areas with a polymer-modified concrete mix enhances durability, with ASTM C946 specifying minimum compressive strength of 4,000 psi. Sealants create a hydrophobic barrier, reducing water absorption by 90% or more, as shown in a 2019 Journal of Materials in Civil Engineering study. The study also noted a 70% reduction in scaling recurrence when sealants were applied after proper surface preparation. Regular maintenance aligns with OSHA guidelines for workplace safety, minimizing downtime and repair costs. For example, the U.S. Department of Transportation reported a 25% decrease in scaling-related maintenance costs for infrastructure using sealant treatments. In summary, combining mechanical cleaning, targeted repairs, and sealant application addresses scaling’s root causes and extends concrete lifespan.
