    • HYPERDESMO® (CLASSIC VERSION)

    HYPERDESMO® (CLASSIC VERSION) is a one component, low viscosity, polyurethane fluid that cures with the humidity in the atmosphere to produce a highly elastic membrane with strong adhesion to many types of surfaces. For over 30 years, it has provided a simple solution for waterproofing and protection. It is based on pure elastomeric hydrophobic polyurethane resin plus special inorganic fillers, which result in excellent mechanical, chemical, thermal, UV and natural element resistance properties.

    As the main waterproofing membrane in car park waterproofing systems.

    TYPICAL SPECIFICATIONS

    HYPERDESMO® Liquid Applied Membrane having a CE mark certification for expected 25 years’ service life shall be applied in 2 coats over a primer coat of MICROSEALER-50 on the prepared surface. The cured membrane shall have tensile strength >8 MPa, adhesion to the substrate >2 MPa and elongation>500%.

    SURFACE PREPARATION

    All waterproofing treatment performances are based on the soundness and suitability of the surface. The surface shall be cleaned from all loose materials, oil, laitance and any other construction debris. The surface shall be free from spalling and unevenness, if in case the surface is very uneven, then it shall be resurfaced using polymer modified repair mortars

    APPLICATION OF PRIMER

    AQUASMART® -DUR shall be mixed well and applied using roller /brush over the prepared RCC surface as a primer that shall be self-cured.

    JOINT FILLING

    Joints and inner angles should be treated with polyurethane based sealant HYPERSEAL®-EXPERT-150 or HYPERSEAL®-25LM-S.

    APPLICATION OF WATERPROOFING MEMBRANE

    Since the exposed terrace area is subjected to thermal stress, it is strongly recommended to provide highly elastic (Having High Elongation property) PU Based seamless coating (HYPERDESMO® Liquid Applied Membranes) also having CE Certification for 25 Years’ Service Life. HYPERDESMO® CLASSIC is mixed well and applied using roller/airless spray in two successive layers over the primed surface. For abrasion resistance and colour protection, the aliphatic pigmented protective top coat is highly recommended (HYPERDESMO® -ADY-E).
