Patching Adhesive to get a Pond Liner

Using flexible pond liner allows you produce a water feature in any form and depth you would like. The thick liner is powerful, but it is not impervious to damage from the components or encroaching plant roots. When holes appear on your pond liner, there are lots of products that work jointly adhere the stain to the damaged region. If you have fish in your pond, then pick products that are nontoxic to fish.


Before it is possible to apply any type of pond liner adhesive, you must wash the region. The adhesive will not stick nicely if the area is dirty. Drain the pond below the amount of the damaged region, which may mean draining it entirely when the hole is at the bottom of the pond. Jagged pieces of liner can make wrinkles on your area, so cut around the edges of the damage, making the edges as neat as possible. Acetone works well to wash the area because it removes dirt and residue. It also dries quickly, letting you move on to this patching faster.


Most pond liner adhesives require an activator, also referred to as a seam primer, to work properly. When you cut a bit of extra liner to cover the hole, lay it in place and trace it using a slice of chalk so you know where to put the activator. Activators are usually implemented using a paintbrush or foam brush, and you must apply the activator to the existing liner inside the chalk line along with the stain. Allow it to sit for about 15 minutes before the activator gets tacky so it can enable the glue securely.

Tape or Glue

Pond glue comes in the form of tape or glue. For double-sided liner tape, cut it to fit, using small, overlapping bits to go around a circular mend. Peel off one side of the backing and press it in place on the liner, addressing the activator. Once the area around the damage is covered over the liner, peel the upper layer of covering the double-sided tape and then press the patch in place, going over it with a hand roller to be certain it’s fully stuck. If you are using glue, spread it over the activator using a paintbrush or squirt it from zigzag lines.

Seam Cover Tape

To completely protect the stain, top it with sloping cover tape. This tape is similar to the double-sided seam tape, however, it is glue on only 1 side and usually wider than the double-sided seam tape. Paint the activator and press the seam cover tape on securely once the activator gets tacky. The opposite roller can make sure it’s evenly pasted, removing any air bubbles.


For the last glue that creates the very first line of defense against a leaking patch, coat the outer border of the seam cover tape with rubber sealant, which usually comes from caulk form. Squeeze a wax along the tape edges. Rubber sealant for ponds is usually dark, but you can find it in clear, green or other colors to match your liner and help the stain blend in.
