• Multi-purpose acetoxy silicone for most sealing jobs around the home
• Contains a fungicide to resist mould on the sealant surface
• Skins in minutes and stays permanently flexible for up to 20 years
• Excellent adhesion to glass, glazed tiles, many plastics and most paints
• Water resistant, so it suits kitchens, bathrooms and areas of high humidity
• Conforms to BS EN 15651-1, 3:2012
• Five colours, single cartridge or trade box of 25

First, clean the surfaces so they are dry and free from grease, dust and old sealant. Acetoxy silicone grips best on non-porous surfaces like glass and glazed tiles.

Next, cut the nozzle at 45 degrees to the width of the gap and apply an even bead with a standard sealant gun. Then smooth the bead within a few minutes, before it skins, using a wetted finishing tool.

Also note the vinegar smell while it cures is normal for acetoxy silicone and clears as it sets. Keep the room ventilated.

Finally, avoid acetoxy silicone on mirrors, bare metals, natural stone, marble and concrete, because the acid cure can corrode or stain them. For those, use our neutral cure Ulti-Mate instead.

Where should I not use acetoxy silicone?

Keep it off mirrors, bare metals, natural stone, marble and fresh concrete, because the acid released during cure can corrode or stain them. For those surfaces use our neutral cure Ulti-Mate.

Why does it smell of vinegar?

That smell is acetic acid, which is normal for an acetoxy silicone as it cures. It clears once the sealant has set, so keep the area ventilated.

Does the fungicide stop black mould?

It helps resist mould on the surface of the sealant. For permanently wet areas like shower trays we recommend Xtreme anti-mould silicone, which is guaranteed mould-free for up to 10 years.

Can I paint over it?

No, silicone will not accept paint. If you need a paintable joint, use Super-Mate siliconised acrylic instead.

Is it suitable for aquariums or pools?

No. This is a general purpose household silicone, not a specialist tank or pool sealant.

How soon can it get wet?

Allow it to cure fully before heavy water exposure. A surface skin forms in minutes, but full cure through the bead takes around 24 hours per 2 to 3 mm.

Single or box of 25?

Buy one cartridge for a small job, or the trade box of 25 for regular sealing work.
