Construction requirements

Base layer treatment: The base layer must be firm and firm, with a smooth, dry surface, free of sanding, scumming, and obvious water collapse. The corners of yin and yang are rounded. The defective base can be treated with BPE-203 epoxy resin base treatment agent. Thoroughly remove debris, dust and oil stains before applying the film.

Construction of waterproof layer of coating film: brush, roller or spraying method can be used, and the coating should be applied in layers, preferably 3 to 4 times. The next pass should be cured in the previous pass and formed perpendicular to the direction of the previous pass. The general interval is 4h ~ 7h (depending on temperature). The thickness of the coating is 1.0mmn, and the total amount of coating (2.2 ~ 2.6) kg / m2.


Before the concrete of the bridge deck is finally cured, it is better to perform regular and uniform brushing treatment on the concrete surface.

The construction of waterproof layer can only be carried out when the concrete strength of bridge deck reaches at least 70% of the design strength.

Waterproofing of bridge deck expansion joints, anti-collision wall expansion joints, bridge deck drains, etc. shall be handled separately according to the bridge structure waterproof design.

The construction temperature is preferably 5 ℃ ~ 35 ℃. When the temperature is less than 5 ℃, rainy days (including the expected rain within 6 hours after construction) are not allowed.

The waterproof layer is not completely dry. Do not allow people to walk and drive vehicles to prevent sharp objects from piercing the waterproof layer.

Storage and transportation

Products are packaged in clean, dry and closed plastic drums or iron drums lined with plastic bags. The volume is 25kg / drum, 50kg / drum, 200kg / drum.
