• Siliconised acrylic sealant that can be overpainted, unlike pure silicone
• Improved adhesion compared with conventional acrylic caulks
• Contains a fungicide to help prevent mould growth
• Permanently flexible, long lasting seal for frames and general decorating
• Interior and exterior use on timber and metal frames, plus internal PVCu frames
• Also bonds polystyrene coving, tiles and wood block flooring
• Single cartridge or trade box of 25

First, check the surface is clean, dry and sound. Super-Mate grips most building materials without a primer, but loose or dusty surfaces should be brushed down first.

Next, cut the nozzle to the gap width and gun an even bead into the joint. Then smooth it within a few minutes with a wetted spatula for a clean, paint-ready finish.

After that, leave the skin to form before overpainting. Water-based paints can usually go on within about an hour; oil-based paints need longer.

Finally, remember this is a decorators' sealant for joints with limited movement. For sanitary joints around baths and showers, use a silicone such as Xtreme or S3 instead.

Can I paint over Super-Mate?

Yes. That is the main reason to choose it over silicone. Let the skin form first, then water-based paints can usually be applied within about an hour.

What is the difference between this and a silicone sealant?

Super-Mate is a siliconised acrylic, so it overpaints and tools cleanly for decorating. Silicones like Ulti-Mate flex more and resist water better, but they cannot be painted. Pick acrylic for frames you will paint, silicone for wet or high-movement joints.

Is it suitable for bathrooms?

Only for dry decorating joints. For baths, showers and other wet areas choose a sanitary silicone such as Xtreme anti-mould or S3.

Can I use it on PVCu windows?

Yes, for internal sealing around PVCu frames. For external PVCu joints a neutral cure silicone usually performs better.

Will it stop draughts around a frame?

Yes, it is ideal for sealing gaps around timber and metal window and door frames with limited movement.

Does it need a primer?

No, it has improved adhesion to most common building materials. Just make sure the surface is clean, dry and sound.

How should I store it?

Keep cartridges cool and dry, ideally between +5 °C and +15 °C, and use within 24 months.
