EVO-STIK Strong Stuff Waterproof Adhesive, Superior Strength, Can be used underwater, Colour: White

Amazing product! I was a but sceptical as I wanted to put mirrors on the landing. Was afraid they were going smash down the stairs. The product is a life changer. No way those mirrors are ever coming down.Don't put up anything you're planning to take down. This is a glue for life.

Beware this adhesive is white and drys white! It sticks well but if it's used somewhere it would be seen best stick with CLEAR ADHESIVE, having said that it stuck my wooden doorbar rock solid after 24 hours!!

strong stuff

I used this to attach weighty decorative curtain tie back hooks to the wall as I am unable to drill into the walls. This worked a treat unlike another very well known brand which I had used previously. They stayed on pretty quickly without having to stand and hold them for ages, it wasn't too messy to work with and they have stayed on and are used daily. I would recommend to anyone.

Used this to insulate the inside of a toilet cistern that was suffering with condensation, this stuff has stuck very well to the mat and the cistern.

Used to repair a bath plug fitting and eady to apply. Excellent adhesion.

Used it to hold side of bumble in place but doesn't hold

I used this to stick down a rubber washer on a broken plastic cistern mechanism. (The part is discontinued and my only other viable option was to purchase and install a new toilet.) For the most part, the washer is submerged. This has worked well and grips the washer firmly to the moving part despite the water resistance. This product has done everything that can be expected and I'm very happy with it. Highly recommended.
