MS300 Marine Sealant, Window Sealer, Pond Sealer for Leaks Concrete Glass Metal, MS Polymer Adhesive 4x Stronger than Aquarium Silicone Caulking, Black Pond Liner Marine Adhesive Sealant, 300ml

Good product

Quite awkward to work with, it sticks like mad to anything it touches, other than where you want it to stick or course. Cleaning it off your skin and nails afterwards is a challenge! But it cures very quickly even in cold weather and underwater and cured my leaky pond problems.

Great product. Really does what you hope it will. It is very good at fixing pond liners BUT I have to take off a star because No matter how careful you are it will get on something that you don't want it too. And anything that touches that, or touches the thing that touched that And it's impossible to get off.

As described

Easy to apply, Nice & sticky (wet finger before touching) and invisible on black liner. Most importantly, pond no longer leaks!! Would definitely recommend

Seams like decent stuff, but would not adhere to a pond liner and concrete seam and had all fallen off by the following day.

Good product

The advertising says this product is suitable for all pond liners. The product itself clearly says that is is not suitable for plastics liners - such as HDPE I assume. This may explain why some of the reviews say that it does not stick

Our rubber lining seam had come open below the water line due to drought and the ground moving. When we realized that we needed help fast. This stuff worked perfectly. Caulked the open seam right in the water and pressed it closed with some rocks. The next day we could refill and the waterline didn't drop. We'll be buying more.

Other than only available in black, this is an excellent sealant.

The item did not come with the screw on nozzle

Arrived with no top. Several other reviews mention same issue.
