How to Use
- Ensure all surfaces are clean and dry, free of wax, grease, dust andany other foreign materials. Metal substrates should be degreased first.
- Cut nozzle at a sharp angle slightly wider than the desired bead or joint width. If being installed as a joint sealant, always use a suitable backing rod to ensure the correct
depth is achieved. - Extrude sealant with a gun and tool with a round spatula within10 minutes to spread the sealant against the joint surfaces.
- Uncured sealant can be removed with mineral turps.
Handy tips
- Can be applied to clean, wet non-porous surfaces e.g. metals, glass, glazed tiles – not wet porous surfaces e.g. concrete, timber. Remove as much water as possible, preferably with acetone. Keep nozzle close to surface so sealant contacts surface immediately. Flatten immediately into joints.
- Adhesion improves on drying.
- Skins in 20 minutes, maximum toughness achieved over several days.
- Paintable with water-based paints after product skins. Pre-test paint over a small section of sealant before completing job. Some paints may require sealant to be lightly sanded before painting.
