Installation guidance

Installation is to be carried out by Bauder Approved Contractors in accordance with the specification and guidelines. Installation Ensure surfaces are clean, dry, and free from debris, grease, fungal growth and any other contaminants before use. Ensure any cracks in the surface are sealed.

LiquiTOP General Purpose Primer should be stored unopened in a dry condition at a temperature of 5-25°C. When stored correctly as detailed above, the shelf life is a minimum 6 months. When manufactured, the product is protected with a layer of nitrogen prior to despatch. This ensures a storage life of six months, provided that the container is left unopened in a dry condition at a temperature of 5-30°C. The layer of nitrogen will disappear and the product will have a limited life once the container is opened. It is also important to note that carbon dioxide will be given off if water enters the container, which can cause pressurisation.
