SIGMA GPS LIQUID GAS BARRIER (£-POA)

SIGMA GPS Liquid Gas Barrier may be applied by brush, roller or airless spray. A minimum dry coated thickness of 1.0mm is needed to provide a gas barrier. To achieve 1.0mm thickness, a total of 2kg/m2 is required, therefore a 15kg tub will cover an area of 7.5m2. 

The background surface should be smooth or have a light even texture, and masonry should be flush pointed and defects in the surfaces made good prior to application. The surface should be clean, sound and free of dust, loose material or free surface water. SIGMA GPS Liquid Gas Barrier should not be applied in wet conditions or where inclement weather is expected before the membrane has dried. The membrane should not be applied in temperatures below 7°C.  Where multiple coats are applied, it is recommended that the coats are applied at right angles to each other. Before application of secondary coats it is necessary to let the first coat become touch dry.  The time required to reach touch dry condition will vary dependant on site conditions within the working area, but will typically be in the order of 1-2 hours in favourable conditions. It is preferable that secondary coats are applied within 24 hours. 

Material is supplied in tubs of 5 & 15kg weight.  Appropriate care must be taken with handling. Clean tools with water immediately after use.

Store tub in conditions between 5°C and 30°C; Shelf life 12 months unopened. 

SIGMA GPS Liquid Gas Barrier is compatible with loose laid membranes supplied by Sigma 360 Ltd such as Sigma GPS Total Gas Barrier.
