Review: This is a very good product provided that you follow the mixing instructions which are on the container TO THE LETTER. I used it to install a protective cover over an existing water meter manhole. This was done on a damp day at a temperature of 12 degrees Celsius. The mixture has a very creamy consistency but you only have about 20 minutes before it starts to set. Very good for filling in cracks on flat surfaces, but a bit too runny to lay bricks.
Review: Great product. Easy to use and solid once dry. I bought this to fill some cracks and holes on a doorstep. The repairs varied, with some being quite deep holes and others just thinner surface cracks. The cement was simple to mix and ready to use within seconds. Once in position, the instructions said it would set in 20 minutes. In reality, it took a bit longer, even on the more shallow areas, but after about 40 minutes to an hour it was solid and ready to be sealed and painted. If you don’t need the full tub in one go, I’d recommend mixing in a separate container so you can keep the rest for later. The cement has now been in place for over three weeks and it seems strong and durable.

Easy to mix and apply. I used it on an external wall where a previous owner had rendered the wall, but not it's past it's life. I filled it with this and then painted it to match.
