How to Use
- Ensure all surfaces are clean and dry, free of wax grease, dust and any other foreign materials. Metal substrates should be degreased first.
- Cut nozzle at a sharp angle slightly wider than the desired bead or join with. 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 within 10 minutes to spread the sealant against the joint surfaces.
- Uncured sealant can be removed with mineral turps
Handy tips
- *Wet Surfaces: 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. For oil-based paints undercoat first with a water-based paint.
- Store in cool dry conditions, below 30°C
Clean Up
