Things You Didn’t Know About Parking Lot Epoxy Flooring Construction

The two most common construction methods are self-leveling and thin-coat.

The thin-coat type has a relatively shallow surface layer, about 0.5~1 mm thick.

Self-leveling epoxy flooring is thicker, at around 2~4 mm. In terms of performance, self-leveling offers a much brighter finish, better flatness, and crucially, far superior wear resistance. For these reasons, self-leveling construction is the mainstream choice for most parking lot projects.

First is base treatment.

It must ensure full bonding between the epoxy coating and the cement base, with consistent color and overall uniformity. The cement base must be level, with a height deviation no more than 3 cm, so that the epoxy material can spread evenly. In addition, the spreading quantity must be well controlled. Normally the material is applied in two passes, with a dosage of about 6~8 kilograms per square meter.

Second is moisture and oil contamination removal.

Proper treatment of moisture and oil on the base is critical to the floor’s service life. Residual moisture will easily cause cracking in the later stage. Oil stains will directly weaken adhesion between the coating and cement base. Some constructors use open flame burning to remove oil, but this can easily damage the cement layer.

Jinfeng Coatings adopts professional detergent emulsification technology to completely decompose and remove oil molecules. This method thoroughly cleans grease without damaging the original base structure.

Third is intermediate coat and topcoat construction.

The intermediate coat should be applied at least twice. This ensures overall structural integrity and allows inspection for defects after each application. Many construction companies skip one intermediate coat to speed up the project. Even if they apply a thicker single coat and pass initial inspection, the risk of hidden defects remains much higher. The topcoat can be well finished by adopting standard self-leveling construction techniques.
