Good!
Does work. Had a leaking shower tray now it’s sorted

Really works and transparent. Great item
Used this to repair my leaky Cotswold stone bird bath which had multiple cracks. Gave it 4 coats over 4 days and it is now holding water and the repairs are good. It has a slight sheen to it but the sealant is transparent so doesn’t change the colour. Very pleased and will probably use again before I pack it away for winter. Comes with two brushes but if you wash residue off you can use it again, great item. Fast delivery.

Won’t mix to right consistency
Cannot work out how to use this. After having it for a couple of months finally got round to opening it. There is a massive lump of slightly soft stuff surrounded by fluid. Appreciate it says to mix it but it’s impossible. The fluid and the lump won’t mix. Useless!

Great stuff - Definitely keeps things dry.
Used this on a hairline crack in my bathroom sink and on a wooden unit where my cat litter tray is stored. It has dried with no smell and does exactly what it says on the tin. I think it's excellent and a little goes a long way. It dried quickly and I used 3 layers over a 6 hour period. Great stuff!

Done exactly what it was bought for.
Had a leak in the shower, it was going behind the tiles and into the kitchen. It did take five coats but it has definitely stopped the water from penetrating the area. We are now leak free.Does exactly what it was supposed to do, and it's completely transparent.

I recommend it
I had some minor leaks on the balcony and decided to try this sealant honestly, it worked well. It’s easy to apply, dries clear, and doesn’t leave any marks. I liked that the kit came with everything I needed, even gloves. It’s not a miracle fix, but for small jobs, it does the trick.
