- Weatherproof
- Can be painted over
- Good all-round-performance with good adhesion to most building materials
Ideal For
- Concretes, PVC and metals
Blockade
How To Use
- Surface should be clean, dry (where possible), free of dust, loose particles and soap residues. If required, clean with mineral turpentine. (For wet application. Refer directions below.)
- Cut blind end off nipple on cartridge and pierce membrane inside base of nipple. Fit nozzle, trim at 45° angle to desired opening and place in a continuous steady flow, pushing sealant ahead of nozzle.
- For a neat finish, tool sealant surface immediately with a spatula dipped in turpentine.
- Skins immediately with maximum toughness achieved slowly over several days.
- Clean up before sealant cures with mineral turpentine or white spirits.
Handy Tips
- Wet Materials: Remove surface water as much as possible. Keep nozzle close to surface so the extruding sealant immediately contacts the surface. Flatten sealant into joint. Adhesion will improve on drying. Where adhesion is difficult, wipe surface with solvent acetone before applying sealant. Blockade will seal wet non-porous surfaces such as metal, glass, tiles. However, adhesion may be difficult on some wet porous surfaces such as concrete or wood.
- Not recommended for sealing water containment structures or for permanent water immersion.
- For best results in large joints use bond breaking backing material to limit sealant depth.
- Blockade may damage some plastics such as styrene foam – test a small area before proceeding.
- In cold weather store at room temperature for easier use.
