Acrylic Elastic Roof Waterproof Coating

A high-performance water-based elastic coating based on pure acrylic emulsion; the film flexes with the substrate to resist cracking and offers good low-temperature flexibility, specially designed for waterproof and crack-resistant intermediate coats on flat/sloped roofs; breathes but stays watertight, eco-friendly and non-toxic.

Recommended Coating System

For concrete substrates, apply epoxy sealing primer first, then the waterproof layer; details matched to site conditions.

Sealing Primer

Epoxy sealing primer (H53-1) to seal and enhance adhesion on concrete substrates.

Elastic Intermediate

Acrylic Elastic Roof Waterproof Coating, applied in 2 coats to design thickness.

Topcoat Protection

Acrylic polyurethane topcoat as needed to improve weather resistance and decoration.

Note: Specific surface preparation grade, number of coats, DFT, overcoating interval and drying time are subject to the official JIANBANG Coatings TDS; we will match a dedicated system one-to-one based on your substrate and working conditions.
