LIQUID APPLIED MEMBRANES

Liquid-Applied Membrane Is a Popular Choice Because It Is...

• Ideal for exposed roofs with large number of complicated details and penetrations

• Cost-effective, especially for roof renovations and roof repair projects

• Seamless, fills in cracks, gaps and voids in substrate

• Easy and safe application

• Durable

• Rapid curing and excellent adhesion to all kinds of surfaces

• Applicable for a multitude of waterproofing needs, not only roofs

Water-based liquid applied membranes and roof coatings were one of the first technologies for liquid applied roof waterproofing, and still have significant importance in the market.

Due to their low hazards characteristics, excellent UV stability and ease of application, acrylic emulsions and polyurethane modified dispersions are becoming popular, particularly in warm and moderate climate regions.

One-component polyurethane based liquid applied membranes and roof coatings were invented in the 1960s and represent an indispensable technology in today’s roofing industry.

Due to their high mechanical properties and flexibility, particularly at lower temperatures, as well their capability to cure under a wide range of conditions, polyurethane based liquid applied membranes can also be used in climatically challenging environments.

The demand for two-component polyurethane/polyurea (PU/PUA) based liquid applied membranes has risen in the last decade.

The fast and efficient application method by two-component spray machines makes it particularly suitable for large surface application and industrial application. Once the product is mixed in front of the application nozzle and applied to the surface it cures within seconds, allowing a fast over coating or early pedestrian traffic.

Sika has adapted the two-component PU/PUA hybrid technology to cold applications and hand-applied systems, making it now possible to do installations where hot spray is not efficient, while maintaining the same performance characteristics.

Bitumen liquid-applied membranes are the perfect solution for seamless, fully-adhered and safe systems. They are polymer-modified bitumen emulsions which require no torch or flame to be applied. They are available as water-based or solvent-based coatings.

Main uses include :Below-ground areas facing ground moisture, such as foundations, Wet areas, Swimming pools, Renovation projects, Detailing, As an adhesive to bond lightweight thermal insulation boards & Typical for residential and industrial buildings.
