Sealing

When sealing a pond, you must first make sure of a few things.  You want to make sure that the pond is rid of any dirt and debris, as dirt and debris can cause a barrier between your seal and concrete, which can eventually cause cracks, and leaks, and allow bacteria and fungi to grow through your pond.  Along with ridding your pond of dirt and debris, you will also want to make sure that it is dry.

Once the pond is dry and clean, you want to apply a layer of sealer to a section of your pool.  We suggest not applying sealer to the entire pool at once, as you will have to smooth out the layers to avoid clumping and dips where cracks or imperfections may have formed.  It is suggested to use a paint roller to apply the sealer.  Use extension rods as needed, as you do not want to walk over any fresh sealant.

As you apply the first layer of sealant to sections of your pond, you will then want to cover the pond with a tarp, held down by stones or bricks or weights.  Tarping the pond will prevent any moisture, dust or debris from landing on the pool, resulting in an even, clean surface.  Allow the first layer of sealant to dry for at least 24 hours.

Once the sealant has dried, you will want to apply one more layer, following the same process.
