GorillaWaterproof Black Coat & Seal Spray, 450ml – Flexible, Weatherproof Liquid Sealant | Seals out Water, Air & Moisture | For Roof Tiles, Brick, Wood, Metal, Concrete, Stone, Rubber, Plastics*

This is the stuff you want if you need a water tight seal on pretty much any surface.We had some conversions done on out new fleet of vans which left exposed wood on the bottom of the Luton bodies. Not ideal given the weather.Brought a can of this stuff to spray seal the exposed wood and it worked like a charm. One can did several vehicles. Goes on very easily, only a couple of light coats is more than enough. Touch dry in perhaps 20 mins and fully cured in less than 24h.Once its fully dried is hard rubber and fully water tight.Would highly recommend this for the price and also consider the paint on version if spraying isn't an option.

Worked perfectly in two isolated places,

Ok.

fixes leeks no prooblem

Not as good as I was expecting a bit too thin when it sprayed out

Excellent product can’t go wrong with gorilla products

Good stuff

We had a crack in our guttering and I really didn't want to replace it so did some research and found this waterproofing spray. I've bought many Gorilla products in the past so trust them and thought I'd give this a go - I haven't had to replace my guttering at all, it's sealed it incredibly and is so easy to use. I've already got another one for my parents to have in stock for sheds and their stable roofs. Such a fab product I'm really impressed!
