Promac Rubber Duck Liquid Rubber is a high-build, flexible acrylic waterproofing coating designed to protect surfaces from water penetration and environmental damage. It is applied as a thick liquid that cures into a seamless, rubber-like membrane, creating a durable barrier against moisture.
 
This coating is engineered for extreme conditions, offering resistance to UV exposure, temperature changes, and weathering, making it ideal for roofs, parapet walls, flashings, and other exposed surfaces.
 
Its flexible formulation allows it to expand and contract with the surface, helping to bridge hairline cracks and prevent water ingress over time.
 
Suitable for both interior and exterior use, Liquid Rubber adheres to a wide range of substrates including concrete, fibre cement, metal (primed), timber, and masonry, making it a versatile waterproofing solution.
