### ⭐⭐⭐⭐⭐ Great quality and great colour

Great quality, perfect dark brown colour. We have dark wood panels on the kitchen ceiling with spotlights.

This brown sealant was perfect , exact brown colour i was looking for ,went on so smoothly and has no smell. Very happy with my purchase.

### ⭐⭐⭐⭐⭐ Very good product
*by B***Z on 5 February 2026*

Quality stuff for any job , easy to apply and smooth off. Sets perfectly , no complaints

### ⭐⭐⭐⭐ Seals and glues
*by D***R on 19 July 2024*

Use I got this to glue aluminium tread plate onto flat steel plate to avoid having to buy more expensive tread like stainless steel which I can't weld. Value This was on offer cheaper than certain DIY store with yellow and blue logos. I think it was £7/8 instead of £12 and it's a biggish tube compared to some smaller silicone sizes. Consistency It's somewhat sticky and I used a narrow bead which was quite hard to pump out. When I aligned the two pieces I had a bit of resistance trying to press them together and used clamps in the end. Hold/stick Once together and dry the pieces are held together very well. It's nice to have a seal as well as a glue. Colour I got Graphite colour which is quite nice and dark grey. Smell No noticeable smell. Overall I would recommend and will use again if I have the need for both a sealant and glue-like substance.
