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

Arrived on time- haven't used it yet.

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.

Ok.

Good stuff

I used this product to seal a crack in a water butt for the garden, it did the job however it did take a number of coats to completely seal the butt

fixes leeks no prooblem

used to seal the insides and bottoms of wooden planters after drilling a few drainage holes in the bases.

Doing what’s it meant to do, just hope it lasts
