Useful for bricklayers
The best plastersiser. Using it years and never have problem. Making the muck soft and easy to use it. Of course recommend it.

Be Careful Storing It - Container Leaked
When I finally was ready to use this (a few months after getting it) I noted the floor where it was had turned brown and was still damp. On further investigation it seems the sealed container had contracted in size and the fairly rigid plastic had spilt and most of the contents had leaked out! Not enough left to use and I was left up with a clean up operation :(

Easy to use, goes a long way
Very Easy to use, good value for money, pointed a patio but only used a jam jar full. Shame they don’t do a smaller size. Just add to mix, makes using a gun easier. Functional.

Seems good but don't judge too soon
I wouldn't have the faintest idea how to do bricklaying but I had some work going on at the house and gave this to my builder - he was just slapping ordinary mortar on my garden walls which I suspect would have cracked and fallen off again just as the last lot did. He said this was a good product. The real test is how is deals with the worst weather and if it does a good job I will upgrade to 5 stars. Until then we can't be sure and unfortunately the same is probably true of all the 5 star reviews written a week after the stuff has been applied.
