When it comes to protecting your home or commercial property against harsh weather, water penetration, and UV damage, choosing the right waterproofing solution is essential. PRO-FLEX Liquid Rubber is a premium acrylic rubberised roof coating specifically formulated to provide outstanding waterproofing, flexibility, and long-lasting protection on virtually all roof types.
Whether you're maintaining an existing roof or protecting a newly installed surface, PRO-FLEX Liquid Rubber creates a seamless waterproof membrane that helps extend the lifespan of your roof while reducing maintenance costs.
What is PRO-FLEX Liquid Rubber?
PRO-FLEX Liquid Rubber is a pure acrylic emulsion that forms a highly flexible rubberised coating once cured. The product is non-toxic, UV resistant, weatherproof, and remains inert after curing, making it ideal for residential, commercial, and industrial applications.
Unlike rigid coatings that crack over time, PRO-FLEX remains flexible, allowing it to move with the natural expansion and contraction of roofing materials.
Why Choose PRO-FLEX Liquid Rubber?
Superior Waterproofing Protection
Water is one of the biggest threats to any building. Leaks can damage ceilings, walls, insulation, electrical systems, and structural components.
PRO-FLEX creates a continuous waterproof barrier that prevents moisture penetration while protecting your property against rain, dampness, and harsh environmental conditions.
Exceptional Flexibility
Roofs constantly expand and contract due to changing temperatures.
PRO-FLEX's advanced rubberised formulation provides:
- Excellent elasticity
- Crack bridging capabilities
- Long-term flexibility

This makes it ideal for areas exposed to extreme weather conditions.

South African roofs endure intense sunlight throughout the year.
PRO-FLEX is specially formulated to resist:
- UV degradation
