Recently, many customers have reported that the floors of their parking lots suffer from surface sanding and dusting. Although the loose sand can be washed away with water, the problem reappears once the ground dries up under repeated vehicle rolling. So how should we deal with this issue effectively?
We should always solve problems from the root cause. When choosing an epoxy flooring construction company, it is advisable to select one with rich construction experience and reliable construction quality. Such professional contractors can formulate targeted solutions according to the actual site conditions.
For example, underground parking lots usually have high ground moisture content and must be equipped with waterproof treatment. By contrast, parking lots on the second floor have much lower moisture content, and waterproofing can be almost omitted, which helps enterprises save project costs.
In addition, we should consider the usage of the parking lot. If large vehicles are allowed to park and drive on site, the floor will require much higher hardness, and the selection of floor coatings must be stricter. Ordinary cement flooring will definitely fail to meet such load-bearing requirements.
Then how to repair floors that have already suffered sanding and dusting?
Experts from Jinfeng suggest that the first step is to judge the severity of sanding, namely the thickness of the loose surface layer.
If only a thin surface layer is sanded while the underlying concrete still meets hardness standards, simply grind off the loose top layer and then apply curing agent for hardening treatment.
If the sanded layer is thick and the overall hardness fails to reach the standard, it is necessary to use epoxy intermediate coating for reinforcement and curing. Only after the base treatment is qualified can the topcoat construction be carried out.
Secondly, refer to the location of the sanding area.
However, if the sanding appears on driveways and frequently used areas, full and standardized construction repair is mandatory.
Finally, different types of flooring materials require different repair methods.
Grind off the unqualified surface layer with a floor grinder to expose the fresh concrete base, then apply concrete hardener for hardening and strengthening.
Reprocess structural joints and cutting joints, level the surface with high-strength cement, grind the whole floor evenly, and apply concrete hardener for consolidation treatment.
Clean, dust and grind the original floor first, then directly construct concrete hardener on the surface.
Remove the original floor layer completely, re-pour new concrete, and then construct concrete hardener and wear-resistant materials.
