1. The ground near the ground is not treated with moisture, and the underground moisture will push up the epoxy coating.
2, the base surface treatment is not complete, the base layer is left with the epoxy resin coating immiscible dirt, such as oil, other one-component paint, glue, etc.
3. During the construction of solvent-based materials, the primer or the solvent-based middle coating is not completely dry, ie, the next step of the process is carried out. As a result, the solvent cannot be emitted, and the accumulated pressure reaches the top of the coating.
solution:
1. Completely remove the original coating, use a moisture-proof primer, or apply a water-based epoxy floor coating; or use a rigid waterproof mortar to apply epoxy coating after construction.
2. Remove the damaged part coating, remove the dirt by grinding or organic solvent cleaning, and then repair according to the design process
3, remove damaged parts, according to the design process partial repair
