FEATURE
Product characteristics
◆The construction process is simple. Mechanical spraying or manual brushing can be used for construction, with fast drying and short construction period.
◆The cost of the waterproof layer is cheap, and the construction achieves the waterproof effect of the bridge deck.
◆The waterproof layer is firmly bonded with the base course and the commercial port asphalt concrete.

Matters needing attention
◆Before painting, the barreled paint shall be stirred evenly.
◆Coating dosage: 1.5kg ~ 3kg/m2, and the film thickness is generally 0.5mm-0.7mm.
◆The construction temperature should be 0-35 ℃, and it is not suitable for construction in rainy days and freezing periods.
◆Machine spraying or roller coating.
Packaging and storage
Packed in barrels, the weight of each barrel is 20kg/barrel, and the storage period is 6 months under normal storage and transportation conditions.
