Installation guidance

Installation is to be carried out by Bauder Approved Contractors in accordance with the specification and guidelines.

Preparation of Metals: Return metal to a clean, bright condition. Ideally steelwork should be prepared in accordance with ISO 12944-4 or BS 7079. Where blasting is not applicable, wire brushing or grinding etc. may be acceptable, although it will be more difficult to obtain the desired condition by these methods. All loose scale or rust must be removed. Galvanised surfaces may be primed after suitable preparation and adhesion testing, especially where the surface is weathered or dull. Bright galvanising will need to be degreased and treated with a proprietary mordant solution before priming. Remove any dust or oxidisation from non-ferrous metals and abrade before priming. Lead should be prepared in accordance with health and safety guidance.

Preparation of Non-Metallic Surfaces: Plastics, coatings, volatile bitumen, etc. should be clean, dry, sound and free from grease. Hard materials should be abraded to provide a key. Adhesion and compatibility tests should be carried out on all non-metal substrates to confirm compatibility. Adhesion tests should be conducted on all non-ferrous and non-metallic surfaces to ensure the suitability of LiquiTOP Epoxy Primer and the subsequent LiquiTOP PU system. Ensure surfaces to be primed are clean and dry and free from stripping agents, grease, dirt, debris or any other contaminants. Pour the contents of the Part B tin into the Part A tin and mix thoroughly for 2-3 minutes until streak free and completely mixed. Apply by brush or lambs-wool roller. Leave the primer to dry for 2-4 hours before the area is overlaid or adhered too, depending on ambient temperature.

LiquiTOP Epoxy 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 12 months provided that the containers are left unopened in a dry condition at a temperature of 5-25°C.
