Hyperdesmo Polyurethane Liquid Membranes.
Polyurethane Liquid Waterproofing Systems: Liquid Polymer applied systems like polyurethane waterproofing membranes offer conclusive advantages over traditional waterproofing systems particularly where seamless systems are desired that are either structurally or aesthetically and for geometrically complicated connections with ventilation outlets or upturns.
Midas Paints Tygervalley and Midas Paints Strand Somerset West Directors, Sean and Ryan Rack have more than 25 year’s experience in all types of waterproofing systems, we consult to a number of leading Architectural practices in specifying the correct waterproofing systems, we assist in technical drawing and designs, we are both founding members of RAWI (Roofing and Waterproofing Institute).
The importance of contractor training cannot be stressed enough, we teach and show. We don’t just sell waterproofing products, we often assist architectural practices with principle details, drawings and specifications for the project to ensure that the contractor awarded the work applies in strict accordance with our specifications. We know and understand the building regulations as we have sat on the SABS subcommittee to assist in rewriting part of SANS10400 part L perusing pertaining to roofing and waterproofing. Our experience in the waterproofing industry is almost unrivalled. We have also attended training on product chemistry and product applicator training with Prof. Weibo Huang at (Qingdao Technological University) an internationally respected polymer scientist.
We stock a whole range of high quality waterproofing products and systems, from the traditional Cementitious Waterproofing, Bituminous Coating Membranes to Polyurethane Liquid Polymer Membranes.

HYPERDESMO® Polyurethane liquid membrane for waterproofing & protection
HYPERDESMO® is a 1 component polyurethane fluid that cures with the humidity in the atmosphere. It produces a highly elastic membrane with strong adhesion to many types of surfaces. It contains a small percentage of xylol, and may be thinned with SOLVENT-01 if necessary. 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. Apply with brush, roller or airless spraying in two, at least, coats with minimum total consumption of 1.5-1.8 kg/m2 .
Waterproofing and protection of:
- gypsum and cement boards,
- polyurethane insulation foams,
- verandas and balconies,
- light roofing made of metal or fibrous cement,
- asphalt membranes,
- EPDM membranes,
- stadium stands,
- car parks,
- bridge platforms
- irrigation channels.
FEATURES & BENEFITS
• Excellent adhesion to almost any type of surface, with or without the use of special primers.
• No thinning is required but SOLVENT-01 may be used.
• 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 90 oC, max shock temperature 200 oC.
• Resistance to 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 any substrate.
• Special additives, like ACCELERATOR-3000A, are available.
• Over 30 years of positive feedback worldwide

Hyperdesmo – The Worlds Leading Polyuerthane Waterproofing System
Alchimica has been providing solutions to waterproofing problems for over 35 years with its extensive range of polyurethane liquid membranes which are the most versatile and long term performing of the liquid applied membrane waterproofing category of products. Our vast product range contains one and two component polyurethane liquid membranes, bitumen extended polyurethanes that can solve any type of waterproofing problems. The systems are applicable to new builds as well as renovation projects. Our products have been applied successfully to numerous applications such as:
- Flat Roof waterproofing
- Wet Rooms/Balconies/Bathrooms
- Water/sewage treatment plants
- Stadium stands or Car Parks
- Bridge decks under asphalt
- Foundation walls and retaining walls
We have a full a full range of primers available to suit different substrates:-
Microsealer 50 is a low viscosity primer that can be used as primer for: Concrete structures (Humid, damp or wet concrete),ceramic tiles, non-porous substrates like glass, marble & metals. Also, for use as concrete sealer.
Geodesmo is a same day primer that can be used on humid, damp or wet concrete, and non-porous substrates.
Aquasmart DUR is an epoxy based primer. Developed specifically for the AQUASMART® range of polyurethane dispersion products as well as Hyperdesmo® and Epoxy range. This primer is used when a humidity barrier is required, sealing coat for concrete, adhesive layer between old and new concrete, Anti-Dust Floor coating, Protective coating for old metal based structures. Also, for use as concrete sealer.
The waterproofing membranes are suited to different applications. The bitumen polyurethane combination products are ideal for below surface applications such as foundations and retaining walls. They are highly elastic and easy to apply.
The Hyperdesmo HAA is a unique single component polyurethane liquid membrane, based on the successful combination of Hyperdesmo and Accelerator 3000 which throughout the years has provided applicators with a solution for a fast curing, bubble free thick layer membrane. Due to its unique formulation, it cures rapidly to form a completely defect free membrane with excellent mechanical and elastomeric properties. This product is ideal for use during the winter months or in climates with relatively low humidity.
Furthermore, the fact that the minimum consumption can now be achieved in only one coat, reduces labor cost and eliminates previous drawbacks of the Hyperdesmo® + Accelerator system such as short working time or problems associated with using Hyperdesmo on its own in multilayer coats adhesion failure. There are over 600 products in the range and we are constantly in R&D formulating advanced solutions.
