Are you facing problems with humidity and the appearance of mold? Follow the application tips of high quality waterproofing products lasting over time and get rid of this unsightly image once and for all! Read how you can seal your roof, balcony, bathroom and basement easily, quickly and efficiently, saving time and money!

HYPERDESMO® - LV is a narrow molecular weight distribution/ low polymer viscosity material and can be applied by airless spray with minimum or zero % solvent addition. Based on pure elastomeric hydrophobic polyurethane resin plus special inorganic fillers, it displays excellent mechanical, chemical, thermal, UV and natural element resistance properties.

It is recommended for waterproofing and protection of:

  • gypsum and cement boards, 

  • bathrooms, 

  • verandas and balconies, 

  • roofs, 

  • light roofing made of metal or fibrous cement, 

  • asphalt membranes, 

  • EPDM membranes, 

  • stadium stands, 

  • car parks, 

  • bridge platforms,

  •  irrigation channels.


The advantages and benefits it provides vary:

  • Excellent adhesion on almost any surface, with or without the use of special primers. 

  • No thinning required.

  • Excellent weather and UV resistance. The white colour reflects much of the solar energy and so reduces the internal temperature of buildings considerably.

  • Excellent thermal resistance, the product never turns soft. Max service temperature 80 oC, max shock temperature 200 oC. 

  • Resistance in the cold: The film remains elastic even down to -40 oC. 

  • Excellent mechanical properties, high tensile and tear strength, high abrasion resistance. 

  • Good chemical resistance. 

  • Non-toxic after full cure. 

  • Water vapor transmission: The film breathes so there is no accumulation of humidity under the coat. 

  • Special primers available for almost every substrate. 

  • Special additives, like ACCELERATOR-3000A, are available. 


Application: 

Product can be successfully applied on: concrete/steel reinforced concrete or otherwise, fibrous cement, mosaic, cement roof tiles, old (but well adhered) acrylic and asphalt coats, wood, corroded metal, and galvanized steel. For information about other substrates, please contact our tech department. 

Concrete substrate conditions (standard):

  • Hardness: R28 = 15MPa

  • Humidity: W < 10%

  • Temperature:  t=5°C-35°C

  • Relative humidity: < 85%

Step 1: Clean the surface using a high-pressure washer, if possible. Remove oil, grease and wax contaminants. Cement laitance, loose particles, mould release agents, cured membranes must be removed. Fill surface irregularities with appropriate products. 

Step 2: Apply the required primer following the guidelines above.

Step 3: Use a low speed (300 rpm) mixer for 2-3 minutes.

Step 4:  Apply the material with roller or brush in two, at least, coats. Do not exceed 48 hours between coats. If more time passes (for example more than 4 days) or if you are unsure of the interlayer adhesion, please contact our technical department.

Consumption: Minimum total consumption: 1.5-1.8 kg/m².

Shelf life – Storage: Can be kept for minimum 12 months in the original unopened pails in dry places and at temperatures of 5°C - 25°C. Once a pail has been opened, use as soon as possible.

Tips: 

Clean tools and equipment first with paper towels and then using SOLVENT-01. Rollers will not be re-usable.

Not recommended for: 

  • unsound substrates (in some cases, application is possible with the use of geotextile reinforcement; please contact our technical department for consultations). 

  • waterproofing of swimming pool surfaces in contact with chemically treated water.

When used in dark colours for exposed use, a protective topcoat of HYPERDESMO®- ADY-E (always pigmented at the desired colour) or HYPERDESMO®-ADY 500 is required. In order to maintain long-term solar reflectance and better colour protection, it is beneficial to apply the aforementioned topcoat layers even when HYPERDESMO® CLASSIC is applied in light colours.
