Icopal Elastoflex LWS Liquid Roofing & Waterproofing System

Icopal Elastoflex LWS Liquid Roofing & Waterproofing System

As part of Icopal’s range of liquid waterproofing systems Elastoflex LWS is designed primarily for use within the commercial refurbishment and new build sectors, Elastoflex LWS offers specifiers and contractors new solutions to previously frustrating and difficult problems.

Elastoflex LWS Coating is a single component polyurethane- based product applied in two layers in conjunction with a polyester reinforcing fleece. It forms a permanently elastic, seamless, yet highly vapour permeable membrane that is both durable and tear-resistant. The coating is suitable for use on both new build and remedial projects.  elastoflex liquid waterproofing system

  • Applications & Intended Use

    "Wet-on-Wet” Application

    "Wet-on-Wet” ApplicationSome liquid systems are installed by applying a base coat, which is then allowed to dry, often over night risking contamination of the surface, before adding the top coat. The system then relies upon the bond between two separate layers.

    Elastoflex waterproofing systems are applied in a “wet-on-wet” application. The top coat is applied while the reinforced base coat is still wet providing total integration of the two layers into a single, chemically bonded membrane. This application avoids the risk of failure from insufficient coverage, lack of inter-layer adhesion from contamination and even delamination.

    Since the Elastoflex coating is applied in one operation, it allows the installation to be completed more reliably and quickly than other methods.

    Intended Use

    Elastoflex Anti-skid Walkway The Elastoflex LWS liquid applied waterproofing system is suitable for use as an exposed membrane on roofs intended for use where normal maintenance foot traffic is anticipated, but may also be used in conjunction with the Elastoflex Anti-skid Walkway System on projects involving more heavily trafficked areas, such as balconies and terraces, for example.
