Hyperdesmo is a one-component, spreadable, elastic polyurethane-based, fast curing, thick layer membrane. It consists of a pure elastomeric hydrophobic polyurethane resin plus special inorganic fillers, which result in excellent mechanical, chemical, thermal, UVA - UVB and natural element resistance properties. Because of its unique composition, it cures quickly and forms a rigid and waterproofing membrane with strong adhesion to many types of surfaces.
Remove all loose mortar, clean the surface and smooth out with cement grinder.
Clean the surface using a 200 bar high-pressure washer and special robotic machine.
Fill joints or cracks with polyurethane mastic Hyperseal 50 FC or Sikaflex 11 FC.
Apply Aquadur, a two-component epoxy coating or Universal Primer 2K-4060, a two-component polyurethane coating to the entire surface and the edges for a height of up to 18 cm, to achieve excellent anchorage of the polyurethane system.
Install the reinforcement, Geotextile 50 Pressed, a polyester textile, to vulnerable areas, where necessary, to reinforce the insulation.
Application of two coats of Hyperdesmo Classic polyurethane membrane with 800% elasticity and a total consumption of 1.5 kg/m2 to 1.8 kg/m2 for complete waterproofing.
The insulation is further reinforced by applying a coat of Hyperdesmo-A 500 or Ady-E fully aliphatic polyurethane fluid to increase resistance to solar radiation and protect the paint.
To achieve the maximum result in the long run, even in the most demanding conditions, we recommend total reinforcement with the Geotextile 50 Pressed membrane on the entire surface.
For better walkability, it is recommended that ADY-E with colour and quartz sand is applied to the entire surface and a second ADY-E coat is applied.
Not recommended for:
Loose substrates like lightweight concretes (perlite, foamed concrete, etc.).
Waterproofing of swimming pool surface that come in contact with chemically treated water.
The benefits of insulating rooftop buildings with Hyperdesmo:
Offers long-term waterproofing.
Has excellent adhesion to concrete.
Cures quickly, i.e., it creates final film in two hours.
Offers vapour permeability
Is resistant to hydrolysis, microorganisms and chemicals.
It forms a continuous waterproofing membrane without joints.
It is extremely resistant to UV radiation as well as thermal and mechanical strains.
The white colour reflects the sun and in the summer months reduces the building’s interior temperature by 3oC to 5oC.
