ISOFLEX-PU 650

ISOFLEX-PU 650 is a one-component, transparent, aliphatic, polyurethane, liquid waterproofing membrane with high solids content. It forms a watertight, elastic and  UV-stable membrane that does not turn yellow over time, while providing excellent mechanical and chemical resistance. Thanks to the high-quality elastomeric and hydrophobic resins it contains, it features long-lasting transparency and elasticity while offering the following advantages:

  • Easy and cost-saving application, since no removal of the old substrate (tiles etc) is required for waterproofing.
  • Effective waterproofing and protection of surfaces with old tile layers, wood, glass bricks, plastic materials, etc.
  • Continuous membrane, without seams or joints.
  • Exceptional resistance to UV radiation and weather conditions (rain, frost).
  • Resistance to detergents, oils, sea water.
  • Resistance to pedestrian traffic.

ISOFLEX-PU 650 is ideal for waterproofing and protection of:

  • Flat roofs, terraces and balconies covered with glazed tiles, ceramic tiles, natural stone, wood, microcement coating, sloped cement screeds, etc.
  • Walls made of glass blocks, natural stone, etc.
  • Sky light domes, artiums and greenhouses made of glass, plastic materials (polycarbonate sheets), etc.

It is also used as a transparent resin binder for decorative stone carpet flooring. Providing high flexibility, it is ideal for applications to balconies and terraces, indoors or outdoors. Moreover, it can be used as  transparent sealing membrane over decorative flake flooring.

Substrate
The substrate must be completely dry, clean, free of grease, loose partivles, dust, old paints, etc. Surfaces with trapped moisture must be left to dry completely prior to the application of ISOFLEX-PU 650.

Application
ISOFLEX-PU 650 should be slightly stirred before application. Prolonged stirring should be avoided to prevent air entrapment. ISOFLEX-PU 650 is applied by roller in two-three layers. Each next layer follows after 12-18 hours, depending on the weather conditions, and not later than 24 hours. Consumption: 0,8-1,2 kg/m2, in two-three laers, depending on the type of the substrate.

Finish
ISOFLEX-PU 650 creates a glossy final surface. If a satin-matt finish is desired, apply one layer of VARNISH-PU 650 MF over ISOFLEX-PU 650.

  •  Surfaces that have been treated in the past with hydrophobic impregnations might cause adhesion problems. It is recommended to test a small area for compatibility prior to full-scale application.
  • If a slip-resistant surface is desired to avoid slipperiness during wet days, broadcast the appropriate type of quartz sand on the final wet coating of ISOFLEX-PU 650.
  • Exceptional resistance to UV radiation and
    weather conditions (rain, frost)
  • Resistance to detergents, oils, sea water
