How to Cement stones around your pond
To cement the stones around your pond, start by mixing up half of an 80 pound bag of Quick Crete. Pour the 40 pounds of concrete into a metal container, add water and mix it together. Add just enough water so that it is not too runny. Put down a base of cement around the pond where you will lay the stones. Lay the stones in the cement, then put some cement in between the stones, and smooth it out.
