Fantastic product
Got this to seal ancient mill stone to make it into a water feature for my pond,(the mill stone held no water previously and leaked like a sieve) This cement stopped all leaks. Easy to put on , brilliant product. Highly recommended

Fixed a leak in my fish pond
Plenty left over to use on other repairs. Difficult to mix with water to get the correct consituency.

Ok but awkward to use
I've used lots of different fillers and cements but never anything as fine as this. Needs very careful mixing to get the right consistency (as other people have said). Seems to harden effectively and I can't yet speak for how waterproof it is.

Does what it says on the bag
Filled cracks around door and door step where water seeped in when there was heavy rain and strong wind. Really happy. So far no water in house and we have had some really wet and windy days. I have never done anything like this before and am really pleased with results and how easy it was to do. Highly recommend

Ideal for ponds.
Bought this to cover cracks in brickwork of a very very large pond - very easy to use ( I am a 68 year old female and I did it myself.) Do not see any leaks. Would recommend.
