If you are doing a pond this stuff is what you need. It will seal almost anything. Great around lights,skimmers and bottom drains. It’s the best you can use to put windows in your pond. It drys like a tuff rubber and sticks like sh** to a blanket. It’s only down side is it’s price. It is expensive. But in my opinion it is the best on the market

Did not expect it to be so easy to use and to work so well. Patch and adhesive made an excellent repair which looks permanent. Would definitely recommend and use again.

Excellent fish safe product sticks like .... to a blanket, used in outdoor applications around a new pond installation, holding decorative pebbles and edging gaps around slabs. Also stabilised small unevenness. So much cheaper than my local garden centre £23.45 a tube there!!

This product does exactly what it says, it will stick under water and sticks to most surfaces, sets hard and firm. I used around my swimming pool because other mastic products did not last. Used this product before and it has a long life.

I bought the product before. It is of good quality and easy to apply. I needed more to complete the all circumference of my pond. I would buy again if needed. It does what it says on the label.
