Good sealant
Had a leak in my porch, so got this to fix it. Had tried other things, but they eventually stopped working.Up to now this is working well. Easy to apply too.

Defo leave good drying time of a few days between repouring and then adding water
This was used to mend a large water feature that sadly cracked over the years. I poured some of the solution in and left for 2 days then repeated a couple of times. It’s worked perfect would defo recommend.

Not for severe water leaks.
This product didn't solve the water leak, however it may help with a minor damp problem.

Easy to use
Being plagued by damp caused by driving rain (by the sea) I painted the wall with this. It's really easy to apply because of its consistency, and is completely transparent. Hard to say yet how effective it is, but time will tell
