Hard RR 500 ECO Waterproofing External area waterproofing membrane

RR 500 ECO is a high performance liquid membrane based on MS Polymer® technology, which provides greater application agility and ensures high durability. In addition, its composition does not dilute with water, ensuring perfect sealing on the roof.

Greater agility in application

Developed with MS Polymer® technology, a high performance raw material that ensures high adhesion power. This eliminates the use of primers and provides less time between coats.

High durability

The anti UVB additives present in the RR 500 ECO composition provide a waterproofing with high durability to weather and climate agents.

Don’t be afraid of raining

RR 500 ECO is composed of prepolymers, fillers, additives that cure with air humidity, forming a high strength rubber membrane that does not dilute with water.
