Boat varnish is best, but not sure how easy it is to get:0)

Thank u sandy much appreciate ur help and advice let's hope someone comes on who uses it and can give me the name also how do attach the pond liner to the sides of enclosure at the mo in his old box i used gorilla tape

Staples would work, or double sided tape. I used the tape used for parcels:0)
But the heat does affect the parcel tape.

Oksandy thanks I may try the heavy duty tape and staple gun

Yacht varnish is the varnish used. Can be bought at most DIY stores. Just give time to cure.
