Polymer modified asphalt waterproof coating is a commonly used building waterproof material. By mixing polymers (such as SBS, APP, etc.) with asphalt, its performance is improved, making it have better elasticity, weather resistance and waterproof effect. The following are its main features and applications:

Features
Good elasticity: The addition of polymers improves the flexibility of the coating and can adapt to the slight deformation of the base layer.

Strong weather resistance: UV resistance, high and low temperature resistance, suitable for various climatic conditions.

Strong bonding: It is firmly bonded to the base layer and not easy to fall off.

Easy to construct: It can be sprayed, brushed or rolled, suitable for complex parts.

Environmental protection: Some products are water-based, environmentally friendly and odorless.

Application
Roof waterproofing: used for waterproofing layers of flat roofs and sloping roofs.

Basement waterproofing: suitable for basement floors, side walls, etc.

Bathroom waterproofing: used for waterproofing treatment of bathroom floors and walls.

Bridge waterproofing: used for bridge deck waterproofing to prevent water from penetrating into concrete.

Construction steps
Base treatment: Make sure the base is flat, clean and crack-free.

Primer application: Enhance the adhesion between the paint and the base.

Paint application: Apply evenly to ensure no omissions, usually 2-3 layers are required.

Maintenance: Maintenance is required after construction to avoid damaging the waterproof layer.

Precautions
Environmental requirements: The temperature should be above 5°C during construction, and rain and snow should be avoided.

Material storage: Store in a cool and dry place, avoid direct sunlight.

Safety protection: Wear protective equipment during construction and keep ventilation.

Polymer modified asphalt waterproof coating has become an ideal choice for building waterproofing due to its excellent performance and wide application.
