Strong and quick drying
I make chess pieces and tried with plaster but too light and soft. Used this and great results really strong and tough cement

Excellent product
I was able to cement my waterfall with this product, over a few days. As long as it is kept moist it can be smoothed and flattened and looks good. I would highly recommend it particularly as it doesn't have lime in it and is safe to use with ponds.

Excellent performance.
Excellent value and performs exactly as described if you follow the instructions. Dries very quickly and can be left with a smooth, hard finish. Ideal for small jobs where speed is a priority.
