The brick shell is now complete, now I need to finish the project.  Bricks do not hold water very well so I will need to seal the bricks and paint.  I was a bit concerned with types of materials to use for sealing the pond because of toxic chemicals leaching into the water.  It is really hard to seperate the hype from facts here because everyone want to seperate me from my money or protect themselves from lawsuits.  I wound up going to the local paint store and spent a day reading labels.  I chose Dry-Lock sealer (water base) and a plain old outdoor paint for a top coat.

Step by step

After the shell is built you need to clean everything up before you seal.  I cleaned and washed the interior before I painted.  I waited about 10 days for the mortar to cure before I sealed the interior.  Dry-Lock does not go far on bricks and mortar.  I used about 6 gallons on two 10X3 foot walls, two 3X3 foot walls and the 10X3 foot base.  When I bought my sealer, I had them add a tint to make the sealer a pretty auqa color.  I did not realize that murky pond water would not look very nice with the bright background and that algae growth would make it look even worse.  I put on about 3 to 4 coats of sealer, washed, allowed to dry then top coated.  I top coated with a brown tint to match the color of the pond water, you can choose any color you like.

I choose to use a pipe in the side of the pond with a skimmer to keep the pond clean.  My 1 1/2" pipe did not have enough head pressure to keep the filter pumps primed, so I had to add another layer of bricks.  While I was adding the bricks, I decided I wanted to have a wider boarder around the pond for leaning on and holding plants and fish food.  To hold the boards on, I drilled holes in the bricks and put bolts through them before I mortared them in.  I then drilled holes in the boards to go over the bolts and held them down with fender washers and nuts  I then painted the outside of the pond to cover up most of my brick laying errors..
