HYPERDESMO®-2K-W is a two-component, solvent-free, thixotropic coating, based on high quality elastomeric polyurethane resins. After polymerization it produces a strong, elastic, hydrophobic membrane suitable for waterproofing and protection. It is recommended for waterproofing of water tanks. It has been certified for use in potable water tanks (more details available on request from our technical department).

Apply with roller in two coats with consumption per coat of 700 gr/m2. On the tank floor, a single coat of 1400 gr/m2 is sufficient.

On tank surfaces with direct exposure to sunlight, HYPERDESMO®-2K-W will discolor. This is purely visual, it does not affect the performance of the product.
