SIGMA GPS Liquid Gas Barrier can be used to protect most building surfaces form the effect of liquid and water vapour, carbonation and as a gas barrier to prevent the ingress of Methane, Carbon Dioxide and Radon. As the product is a barrier to moisture it can be used as a DPM on floors and walls.
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.
