Closed Loop Cooling Water System.Liquid-applied membrane LAM is a monolithic, fully-bonded, liquid-based coating suitable for many waterproofing and roofing applications.
The coating cures to form a rubber-like elastomeric waterproof membrane and may be applied over many substrates, including asphalt, bitumen and concrete. 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. 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 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's Expert Roof Knowhow. This temperature difference indicates that they are urban heat islands. The main cause of urban heat island effect is the modification of the land surface in cities. Natural vegetation is replaced by the built environment.
Most surfaces of new structures are characterized by low solar reflectance and high impermeability.It cures to form a seamless and durable waterproofing solution for exposed roof areas and structures.
Higher storage temperatures may reduce shelf life of product. Reference shall also be made to the storage recommendations within the safety data sheet.
Note: These figures are theoretical and do not include for any additional material required due to surface porosity, surface profile, variations in level and wastage.
Other substrates must be tested for their compatibility. If in doubt, apply a test area first. High temperatures combined with high air humidity will increase the curing process.
Thus, material in opened containers should be applied immediately. In opened containers, the material will form a film after 1 hour approx. Note: Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity. The surface must be sound, of sufficient strength, clean, dry and free of dirt, oil, grease and other contamination. Depending on the material the substrate must be primed or mechanically cleaned.
Grinding may be necessary to level the surface. Suitable substrates are such as: concrete, bituminous felts and coatings, metal, brickwork, asbestos cement, ceramic tiles, wooden substrates.
For detailed information regarding substrate preparation and primer chart please refer to Method Statement No. Stirring gently will minimise air entrainment.
Damageable areas handrails, etc have to be protected with tape or plastic wrapping. Please note, always begin with details prior starting with waterproofing the horizontal surface. For details follow step Clean all tools and application equipment with Thinner C immediately after use. Product Data Sheet Show all documents.
